What could impact the longevity of your EV's battery?

15 practical tips that could help your EV battery stay in good shape

Your EV does most of the hard work when it comes to managing its battery, but there are still some simple things you can do to help it perform consistently over time. Every EV is slightly different, so your vehicle manual is always the best place for specifics – but these general principles apply across most modern lithium-ion batteries.

1. Keep your everyday charge between 20% and 80%

Like your mobile phone or laptop, most EVs have lithium-ion batteries, which generally prefer being kept in the middle of their charge range. Staying between about 20% and 80% during day-to-day use could help reduce the stress caused by repeated full charges or deep discharges. Many EVs let you set an automatic charging limit, and some pause charging around 80% by default. You can always lift the cap when you need more range — but for most days, midrange charging keeps things simple and stable.

2. Charge to 100% when you need the range

Occasionally, a full charge can still be effective – when you’re getting ready for a long journey, for example. Most modern EVs also use a Battery Management System (BMS) that can manage charging safely all the way to 100%.

If your car has a “charge to full by departure” feature – often labelled ‘Scheduled Departure’ or ‘Next Departure’ – it’s worth using. It times your charge so your car reaches the level you need just before you unplug, which helps avoid the battery sitting at 100% for longer than necessary.

3. Protect the battery from extreme temperatures

Lithium-ion batteries are sensitive to heat and cold. High temperatures can increase stress on the cells, and very low temperatures can reduce range and slow charging. You can’t control the weather, but small choices help — like parking in the shade on hot days, using covered parking in winter, or letting the car precondition before you set off if it supports it.

4. Expect different charging behavior in very hot weather

When you plug your EV into a charger, it usually charges quickly at the start – before slowing down as your battery fills up. In very hot weather, your EV’s Battery Management System (BMS) might step in to reduce charging speed earlier in your charging session to protect from overheating.

To make charging easier in hot weather, try plugging in during cooler times of day, like the evening or overnight. This reduces the amount of heat the car has to manage and helps the battery stay closer to its ideal temperature. Your vehicle manual will also explain how your specific model handles high temperatures and any settings that can help.

5. If you don’t drive often, use the car occasionally

EVs don’t need daily use, but if your car spends long periods parked, taking it out now and then helps keep the battery and other systems in regular operation. You don’t need long trips — just normal use every so often is enough.

6. Smooth driving reduces short-term load on the battery

Hard acceleration and heavy braking demand more energy from the battery in a short burst. A smoother driving style spreads that load more evenly, which helps your battery operate in a more predictable and consistent way. Efficiency modes can help with this too.

7. Keep your software up to date

Software plays a key role in how an EV manages its battery. Updates often include improvements to charging, temperature control, efficiency, or algorithms the car uses to look after the battery. Installing updates promptly ensures your vehicle is running with the latest manufacturer guidance and protections.

8. Stick to the recommended service schedule

Routine servicing helps technicians spot issues early, check cooling systems, update components, and monitor battery health. Using an authorized service center means your car is being looked after by people trained on its specific systems, including high voltage and thermal management.

9. Don’t store the car at 100% or near empty for long periods

If your EV is going to be parked for a long time, leaving the battery completely full or almost empty isn’t ideal. Most manufacturers recommend storing the car at a midrange charge level — often around 40–60%. Many EVs have a storage or long-life mode that sets this automatically.

10. Precondition the battery before rapid charging (if your car supports it)

Preconditioning warms or cools the battery so it’s at the ideal temperature before you arrive at a charger. When your car supports it, preconditioning helps the battery charge more smoothly and efficiently. Most EVs trigger it automatically when you set up a charging station as your destination in your car navigation.

11. Use scheduled charging

Scheduled charging lets you finish charging shortly before you leave, which avoids the battery sitting at a high state of charge for long periods. It also helps you charge at cooler times of day in summer, which naturally supports battery temperature management.

12. Keep tires inflated

Tire pressure affects efficiency. Underinflated tires make the car work harder, meaning the battery must supply more power for the same trip. Checking pressures regularly — especially when the weather changes — keeps your car running more smoothly and reduces unnecessary energy use.

13. Use cabin heating and cooling efficiently

Climate control is one of the biggest energy users in an EV. Using features like heated seats or steering wheels, preconditioning the cabin while plugged in, and managing cabin temperature sensibly can reduce the amount of power pulled from the battery, especially on very hot or very cold days.

14. Keep cooling intakes and vents unobstructed

EVs rely on airflow and coolant systems to regulate battery temperature. If cooling paths around the underbody or vents become blocked with debris, thermal systems must work harder. Routine servicing usually includes checks for this, but if you often drive on dusty or muddy roads, staying aware of it helps.

15. Use any built-in “battery care” features

Many EVs include tools designed to protect the battery, from long life charging modes to adjustable charge limits, thermal management settings, and scheduled departures. These features are designed to help the battery operate in a stable, predictable way — and they’re worth using.
