Planning to buy a used electric vehicle? Smart decision — but only if you check the Electric Vehicle Service History first.
The used EV market in India is growing rapidly, with prices becoming more accessible every month. In 2024 alone, sales crossed 99,000 units, and many early EV owners are now selling their first cars to upgrade to newer models.
However, unlike petrol or diesel cars, an EV’s service history tells a very different story — especially about battery health, software updates, and long-term reliability. Ignoring it can turn a “good deal” into a costly mistake.
But here’s what most first-time buyers miss: checking service history on an electric car is completely different from what you’d do with a petrol or diesel vehicle. I’ve seen too many people get excited about a good deal on a used Tata Nexon EV or MG ZS EV, only to discover later that the battery’s been hammered or critical maintenance was ignored. That’s lakhs of rupees down the drain, and it’s entirely preventable.
Let me walk you through exactly what you need to look for in those maintenance records. This isn’t rocket science, but you do need to know what actually matters.
Here’s something that surprises most people: electric vehicles need less maintenance than traditional cars, but what they DO need is absolutely critical. There’s no oil to change or timing belt to worry about, true. But the battery alone can cost anywhere from ₹2 lakh to ₹8 lakh to replace, depending on the model.
Think about it this way. With a petrol car, if someone skipped a few services, you might face a ₹50,000 engine repair bill. Annoying, but manageable. With an EV, neglecting the cooling system or regularly fast-charging to 100% in Delhi summer could mean replacing a battery that costs more than many used cars.
The maintenance records tell you whether the previous owner treated this vehicle like a long-term investment or just another gadget. And trust me, you can spot the difference pretty quickly once you know what to look for.
Battery Health Records: Your Number One Priority
Let’s start with what actually matters most: the battery. This is the heart of any electric vehicle, and its condition determines whether you’re buying a solid car or an expensive mistake waiting to happen.
What You Need to See
When you’re going through service records, you want documented battery health checks. Most manufacturers recommend annual diagnostics, especially given India’s varied climate conditions.
Look for these specific details:
State of Health (SOH) percentages – This number tells you how much capacity the battery retains compared to when it was new. Anything above 85% is generally excellent for a used EV. Between 80-85% is acceptable depending on the age and kilometers driven. Below 80%? You need to negotiate aggressively on price or simply walk away.
Degradation patterns – Battery capacity doesn’t drop in a straight line. You want to see gradual, consistent decline, not sudden drops. If the records show the battery went from 95% to 82% in just six months, something’s definitely wrong. That’s a major red flag.
Warranty status – Tata offers lifetime battery warranty for first owners and 8 years/1.6 lakh km for second owners. MG provides 8 years or 1.5 lakh km warranty. Check if this is still active and transferable. Some warranties only cover complete failure, while others guarantee minimum capacity of 70%. The paperwork should spell this out clearly.
Warning Signs That Scream “Problem”
Missing battery health reports are the first red flag. If someone’s owned a Tata Nexon EV for three years and there’s not a single battery diagnostic in the service history, ask yourself why. Either they never serviced it properly, or they’re hiding something concerning.
Another major concern is excessive fast-charging. While modern EVs handle DC fast charging better than earlier models, constantly charging to 100% at high speeds in places like Bangalore or Mumbai traffic does accelerate degradation. If the service notes mention battery conditioning treatments or thermal management issues, that’s your hint the battery’s been stressed beyond normal use.
Brake Service Records: Yes, EVs Still Have Brakes
People think electric vehicles don’t need brake service because of regenerative braking. That’s partially true but also dangerously misleading, especially on Indian roads.
Regenerative braking does most of the stopping work, which means brake pads can last 80,000 to 1,20,000 km or more. Brilliant, right? Not so fast. Because the brakes are used less frequently, they’re actually more prone to corrosion, especially during monsoon season in cities like Mumbai, Chennai, or Kolkata.
What Good Brake Maintenance Looks Like
You want to see annual brake inspections in the service records, even if no work was performed. The inspection should note:
- Pad thickness measurements
- Rotor condition and corrosion level
- Caliper operation
- Brake fluid condition
Brake fluid is the sneaky one here. It absorbs moisture over time. In an EV where the brakes aren’t used as much, this moisture can sit there causing internal corrosion, especially in humid coastal cities. Manufacturers typically recommend brake fluid changes every two to three years. Make sure this was actually done.
If the service history shows the brakes were ignored for five or six years because “EVs don’t wear brakes,” you’re potentially looking at seized calipers or corroded components that’ll need immediate replacement.
Cooling System Maintenance: The Unsung Hero
Most EVs use liquid cooling for the battery, inverter, and sometimes the motor. This system is absolutely vital, especially in India’s extreme temperatures – from 45°C summers in Delhi to cold Himalayan winters.
The cooling system prevents your battery from overheating during fast charging or when stuck in Mumbai traffic. When it’s not working properly, the battery management system will limit performance to protect the cells. You’ll end up with slower charging speeds and reduced power output.
Critical Cooling System Checks
Service records should show:
Coolant level inspections – Should be checked at every major service, typically annually or every 10,000-15,000 km.
Coolant replacement – Manufacturers usually recommend replacement every 50,000 to 1,00,000 km. The important thing is that it was actually done according to schedule, not delayed because “it looked fine.”
Leak inspections – Any mention of coolant leaks, even small ones, should make you investigate further. These systems are under pressure, and leaks can lead to catastrophic overheating, especially on highways.
Pump operation – Some authorized service centers will test the coolant pump operation. If this is documented, excellent. If it’s never been checked on a 3-4 year old vehicle, that’s concerning.
Watch out for service notes mentioning “low coolant level” multiple times. Once could be normal evaporation. Three or four times? There’s definitely a leak that was never properly fixed, just topped up repeatedly.
Tire Rotation and Alignment Records
This might seem basic, but tire maintenance tells you a lot about how the car was driven and maintained, especially on Indian roads with their potholes and speed breakers.
EVs are heavy because of their batteries. A Tata Nexon EV, for instance, weighs about 200-300 kg more than the petrol version. This extra weight, combined with instant torque delivery, means tires wear faster than most new EV owners expect.
What the Records Should Show
Regular tire rotations every 7,500 to 10,000 km keep wear even and extend tire life. If you see this in the service history, it suggests the owner followed manufacturer guidelines and probably took care of other things too.
Alignment records are equally important. If the car needed multiple alignments, especially with notes about hitting potholes or road damage, you’re looking at a vehicle that might have suspension issues. Given Indian road conditions, one alignment is normal. Three or four? That’s excessive.
Uneven tire wear noted in inspection reports is a red flag. It could indicate alignment issues, but it might also mean the previous owner had a heavy right foot and was constantly launching the car hard at every signal. That kind of driving accelerates battery degradation as well.
Software Updates: The Digital Service Record
Here’s something unique to EVs that you won’t find in traditional car maintenance: software update history.
Electric vehicles are essentially smartphones on wheels. Manufacturers regularly release software updates that can improve range, fix bugs, enhance safety systems, and even upgrade charging capabilities. These updates are crucial for models like the Tata Nexon EV, Punch EV, or MG ZS EV.
What You’re Looking For
Most manufacturers like Tata Motors and MG Motor keep update records in their systems, accessible when you provide the VIN at an authorized service center.
You want to see that the vehicle received regular updates, especially any critical safety recalls or battery management system improvements. If the software hasn’t been updated in years, you might be missing out on performance improvements and important bug fixes.
Some updates address specific issues like battery charging limitations, range optimization, or thermal management problems. If the car had any of these issues and the software was never updated, those problems likely still exist.
Recall Completion Documentation
EVs, like any vehicles, sometimes have recalls. The difference is that EV recalls often involve software fixes or battery-related hardware issues that are absolutely critical to address.
Check the manufacturer’s website or dealer for any open recalls on the specific VIN you’re considering. Then verify in the service records that all recalls were completed at an authorized service center.
Battery recalls are particularly important. Some early models across different brands have had battery-related concerns that required software updates or hardware modifications. If that work wasn’t done, you’re inheriting a potentially problematic vehicle.
Software recall fixes should also be documented. These might address charging system bugs or battery management issues that could affect your ownership experience significantly.
Charging Cable and Port Records
This might seem minor, but it matters, especially given the dust and humidity we deal with in India. Check whether the service records mention any charging port repairs, charging cable replacements, or connector issues.
Frequent charging port repairs suggest the previous owner wasn’t careful when plugging in, which could indicate generally careless ownership. Replaced charging cables due to damage rather than normal wear is another hint.
If there are notes about slow charging speeds or the car not accepting a charge properly, investigate further. This could be a simple software issue or a more serious electrical problem that’ll cost you lakhs to fix.
Getting Service Records: Where to Look
Right, so you know what you’re looking for. But how do you actually get these records in India?
Authorized Dealer Service History
The gold standard is authorized dealer service history from Tata Motors, MG Motor, Mahindra, or whichever brand you’re considering. Dealers use manufacturer-specific diagnostic tools and usually keep detailed digital records.
Call the dealer’s service department with the VIN, and they can pull up everything done at their locations across India. For cars that moved between cities or states, most manufacturers’ systems sync this information. You should be able to see service history from any authorized dealer in the network.
Independent EV Specialist Records
Many EV owners use independent specialists, especially in metro cities like Bangalore, Pune, or Delhi NCR. These shops often provide excellent service at better prices than dealers after the warranty expires.
Ask the seller for contact information for any independents they used. Good specialists keep thorough records and are usually happy to verify service history for potential buyers. If the seller can’t provide this contact information, that’s immediately suspicious.
Owner-Maintained Logs
Some owners keep meticulous personal records, especially for work done at smaller garages or at home. While this isn’t as verifiable as dealer records, detailed logs with bills, receipts showing VIN numbers, and photos are better than nothing at all.
Look for photos of work being done, GST invoices with VIN numbers matching your car, and detailed descriptions. If someone’s kept this kind of documentation, it usually indicates they actually cared about the vehicle.
Digital Service History Apps
Modern EVs often include connected services that log maintenance through smartphone apps. Tata EV owners can see service history through the Tata EV app. Similar systems exist for MG Motor and other manufacturers.
Ask the seller to show you this digital history during your inspection. It’s difficult to fake and provides real-time accuracy. This is one of the best verification methods available.
Red Flags That Should Make You Walk Away
Some warning signs are absolute deal-breakers, especially in the Indian used car market:
No service history at all – If someone claims they’ve owned an EV for two or three years but has zero documentation, something’s seriously wrong. Either the car was barely driven, was completely neglected, or they’re hiding expensive repairs.
Gaps in maintenance – If regular annual services suddenly stop for two years, what happened during that time? Were costly repairs needed? Was the car sitting unused in some parking lot, which brings its own set of problems?
Flood or accident damage – This is crucial in India where we have annual flooding in many cities. Even if repaired, water damage to battery systems creates ongoing nightmares. Battery replacement alone can cost ₹2-8 lakh depending on the model. Always check vehicle history reports and look for any unusual electrical work.
Multiple battery conditioning attempts – If service records show repeated attempts to recover battery capacity through conditioning cycles, the battery health is definitely poor and declining faster than normal. This is a money pit waiting to happen.
Commercial registration – If the car was registered as a commercial vehicle (cab, fleet, etc.), run away. Warranty terms are significantly different for commercial vehicles, and they’ve typically been driven much harder.
What About EVs Without Much Service History?
Electric vehicles genuinely need less maintenance than traditional cars. So what if you find a two-year-old Tata Punch EV with minimal service history?
This is where battery health reports become absolutely critical. If the owner can provide recent battery diagnostics from an authorized service center showing good health (above 85% SOH), and the vehicle history report is clean, minimal service history might be acceptable.
However, you should absolutely insist on a pre-purchase inspection by an EV specialist who can run proper diagnostics. This typically costs ₹2,000-5,000 in major cities but could save you lakhs.
Look at tire condition and remaining tread depth. If the original MRF or CEAT tires are still on the car with plenty of tread after two years, the vehicle probably wasn’t driven aggressively or excessively. If it’s on its third set of tires already, someone was either doing serious kilometers or driving very aggressively.
The Pre-Purchase Inspection: Your Safety Net
Even with perfect service records, always get a pre-purchase inspection from someone who knows EVs. Many traditional mechanics in India aren’t qualified to properly assess electric vehicles – they simply don’t have the diagnostic equipment or training.
A good EV inspection should include:
- Battery health diagnostics with complete SOH reporting
- High-voltage system inspection for any damage or corrosion
- Charging system functionality tests (they should actually plug it in and test charging speeds at both AC and DC)
- Brake system condition assessment including corrosion checks
- Coolant system inspection for leaks
- Tire and suspension evaluation (critical given Indian roads)
- Software version check and update status
- Comprehensive test drive including highway speeds and regenerative braking tests
This typically costs ₹3,000-8,000 depending on the city and thoroughness. In places like Mumbai, Bangalore, or Delhi, specialized EV inspection services are becoming common. It’s absolutely worth every rupee for the peace of mind.
Common Electric Vehicle Service History Red Flags to Watch For
When reviewing an Electric Vehicle Service History, certain warning signs should immediately raise concern — especially in the Indian used EV market.
If the service records show frequent battery-related complaints, repeated software recalibrations, or unexplained system resets, it may indicate deeper electrical or BMS issues. A missing record of manufacturer-recommended software updates is another red flag, as outdated firmware can affect both range and safety.
Pay close attention to gaps in service intervals. Unlike petrol cars, EVs rely heavily on preventive checks rather than breakdown repairs. Long gaps often suggest neglected maintenance. Finally, always verify whether major components like the high-voltage battery, inverter, or onboard charger were repaired or replaced under warranty, and if those replacements were done at an authorized service center.
Using Service History to Negotiate
Good service records give you serious leverage when negotiating price. If everything checks out and maintenance was done properly, you know the car’s worth closer to asking price. But if you spot issues, you’ve got solid grounds to negotiate downward.
Missing coolant services or overdue brake fluid changes? That’s upcoming maintenance you’ll need to pay for immediately. Factor those costs (typically ₹5,000-15,000) into your counter-offer.
Battery health declining faster than average? That might mean earlier replacement than typical. A battery at 82% SOH versus 90% SOH could mean ₹50,000-1,00,000 difference in your offer.
Needed repairs noted in recent inspections but not addressed? Those are immediate costs you can deduct from your offer. Don’t be shy about this – it’s your money.
Just remember that well-maintained EVs with complete service history from authorized dealers often command premium prices for good reason. If you find one, it might be worth paying ₹20,000-40,000 more rather than gambling on a cheaper vehicle with questionable history.
Final Thoughts
Checking electric vehicle service history isn’t complicated, but it is very different from traditional cars. Focus on battery health, cooling system maintenance, and regular authorized service center inspections rather than oil changes and engine servicing.
Take your time reviewing the records. Ask questions about anything that seems off. Visit the authorized dealer with the VIN and verify the history yourself. And if you can’t get satisfactory answers about maintenance history, there are plenty of other used EVs in the market right now.
The used EV market in India is still relatively young, which means well-documented cars stand out. With brands like Tata Motors holding over 62% market share and MG Motor growing rapidly to 21%, finding a good used EV from these reliable manufacturers isn’t difficult – you just need to know what to look for.
The right used EV with proper service history can give you years of low-cost, reliable motoring. The wrong one with hidden problems can turn into an expensive nightmare that makes you regret not buying a petrol car. Those maintenance records are your window into which kind of vehicle you’re actually buying.
Do your homework, ask the right questions, verify everything with authorized dealers, and you’ll find a great used EV that serves you well for years to come.
Frequently Asked Questions About EV Service History
Q: What is the average battery replacement cost for popular EVs in India?
Battery replacement costs vary significantly by model. For Tata Nexon EV, expect ₹4.50-5.50 lakh, Tata Punch EV costs ₹4.50-5.00 lakh, and MG ZS EV ranges from ₹6.62-8.50 lakh. However, most owners won’t face this expense due to comprehensive warranties. Tata offers 8 years or 1.6 lakh km warranty, while manufacturers typically replace batteries free if capacity drops below 70% within the warranty period.
Q: How long do EV batteries actually last in Indian climate conditions?
Indian EV owners can typically expect their lithium-ion batteries to last between 8 to 12 years in real-world use, depending on local climate, charging habits, and driving patterns. India’s hot summers and temperature fluctuations can accelerate degradation compared to moderate climates, but modern thermal management systems help protect batteries. With proper care, most batteries will outlast the typical car ownership period of 7-10 years.
Q: Is it safe to buy a used EV without any service history?
Not recommended at all. Without service history, you have no way to verify battery health, whether recalls were completed, or if critical cooling system maintenance was performed. If you must consider such a vehicle, insist on a comprehensive pre-purchase inspection from an authorized service center that includes battery diagnostics. Even then, the lack of documentation is a major red flag that should significantly lower the price you’re willing to pay.
Q: What should the battery State of Health (SOH) be for a used EV?
For a used EV, anything above 85% SOH is excellent. Between 80-85% is acceptable depending on the vehicle’s age and kilometers driven. Below 80% means you should either negotiate aggressively on price or walk away. Research shows that EV batteries typically degrade by 2-3% per year, so a three-year-old car should ideally be around 90-92% SOH.
Q: How often should EV coolant be replaced?
Most manufacturers recommend coolant replacement every 50,000 to 1,00,000 kilometers, though some newer EVs have longer intervals. The important thing is checking that it was actually done according to the manufacturer’s schedule. Given India’s extreme temperatures, this maintenance is absolutely critical and should never be delayed.
Q: Do EVs really need less maintenance than petrol cars?
Yes, significantly less. EVs have no oil changes, no timing belts, no spark plugs, and fewer moving parts overall. However, what they do need – battery health checks, cooling system maintenance, brake inspections, and software updates – is absolutely critical. The maintenance is less frequent but each item is more important. Think of it as quality over quantity.
Q: What’s the warranty coverage on Tata EV batteries?
Tata Motors offers a lifetime battery warranty for first owners and 8 years/1.6 lakh km for second owners on select models. The standard warranty across most Tata EVs covers 8 years or 1,60,000 km. This typically guarantees at least 70-80% battery capacity retention during this period. Always verify the specific warranty terms and transferability when buying used.
Q: How much does a pre-purchase EV inspection cost in India?
A comprehensive EV pre-purchase inspection from a qualified specialist typically costs ₹3,000-8,000 in major cities like Mumbai, Bangalore, or Delhi. This should include battery diagnostics, high-voltage system inspection, charging tests, brake condition assessment, coolant system checks, and a thorough test drive. It’s absolutely worth the investment before spending lakhs on a used EV.
Q: Can I check service history online for my EV?
Yes, most modern EVs offer digital service history through their smartphone apps. Tata EV owners can check history through the Tata EV app, while MG Motor has similar systems. Additionally, you can call any authorized dealer’s service department with the VIN number, and they can pull up the complete service history from their network database.
Q: What happens if the previous owner used too much fast charging?
Excessive fast charging, especially regularly charging to 100% at DC fast chargers in high temperatures, can accelerate battery degradation. This shows up as faster-than-normal capacity loss and may be documented in service notes as thermal management issues or battery conditioning treatments. If you see multiple mentions of this, expect the battery to have shorter remaining life than average.
Q: Is commercial registration a deal-breaker for used EVs?
Yes, absolutely. Commercial registration (for cabs, fleet vehicles) means completely different warranty terms, significantly harder use, and likely much higher kilometers than shown. Additionally, these vehicles were probably fast-charged multiple times daily and driven aggressively. Commercial EVs should be priced much lower than private vehicles, and even then, they’re risky purchases.
Q: What if the car has been in a flood?
Walk away immediately. Water damage to battery systems and high-voltage components in EVs is extremely serious. Even if repaired, you’re looking at potential ongoing electrical issues, corrosion problems, and safety concerns. Battery replacement alone can cost ₹4-8 lakh depending on the model. Flood-damaged EVs are simply not worth the risk, regardless of how good the price seems.
Q: How important are software updates for EVs?
Very important. Software updates can improve range, fix bugs, enhance safety systems, upgrade charging capabilities, and address battery management issues. Missing years of updates means you’re potentially missing out on significant performance improvements and important safety fixes. Always verify that the vehicle received regular software updates, especially any critical recalls.
