How to Extend EV Battery Life

Electric vehicles (EVs) are becoming an increasingly popular choice for drivers who want to reduce their carbon footprint and make a positive impact on the environment. However, while the technology has improved significantly over the years, EV battery life is still a concern for some drivers and this article addresses how to extend EV battery life with a few tips.

By following these tips for charging, driving and maintenance, you can help extend the lifespan of your EV battery and maximise the efficiency of your vehicle.

How long does an EV battery last?

Lithium-ion batteries are widely used in electric vehicles due to their high energy capacities and ability to hold a charge for a long time. These batteries were first introduced in electric vehicles in the 1990s, and they are rechargeable by plugging them in. However, as they pass through cycles of charge and discharge, they can degrade over time, resulting in a decrease in the car's range and the time between charging sessions.

Industry estimates that electric vehicle batteries will last between 100,000 and 200,000 miles, or approximately 15 to 20 years. However, due to their high initial capacity, drivers barely notice any degradation of these batteries, even as they age. A typical electric vehicle loses 2.3% of its battery life every year.

Charging tips to extend EV battery life:

1. Avoid charging your battery to 100%

Charging your battery to 100% can cause stress on the cells and reduce its overall lifespan. Instead, aim to charge your battery to around 80%.

2. Avoid letting your battery level drop too low

While it's important to avoid overcharging your battery, it's also important to avoid letting it get too low. Try to keep your battery level above 20% for optimal battery health.

3. Use a level 2 charger when possible

Fast charging is convenient, but it can also harm your battery. The high current and voltage used in fast charging generate heat, which can degrade your battery's performance over time. If possible, stick to slow charging or level 2 charging, which uses a lower voltage and current.

Driving tips to extend EV battery life:

1. Avoid rapid acceleration

Rapid acceleration can put a lot of strain on your battery, which can decrease its lifespan. Try to accelerate smoothly and gradually.

2. Keep it light when travelling

Just like a petrol or diesel vehicle, the weight of your belongings can affect your electric car's range. To maximise efficiency, try to minimise the weight of your goods and avoid carrying unnecessary items. This can help you travel further on a single charge and reduce wear and tear on your electric car's components.

3. Use regenerative braking

A regenerative braking system works as a generator whenever you brake. It retains energy that would otherwise escape as heat and stores it in a battery so you can travel further.

The energy generated varies based on the system, but typically increases range by a few miles. You can maximise the benefits of the regenerative braking system by driving smoothly, avoiding sudden braking and unnecessary idle time.

Maintenance tips to extend EV battery life:

1. Keep your battery cool

High temperatures can damage your battery and decrease its lifespan. Park your car in the shade whenever possible and avoid exposing it to high temperatures for extended periods of time.

2. Keep your battery clean

Dirt and debris can damage your battery and decrease its lifespan. Clean your battery regularly to keep it in good condition.

3. Keep your tyres inflated

You might think it's a minor thing, but checking your tyre pressure can have a big impact on your EV's range. Tyres with low air pressure create more resistance, which makes batteries work harder.

The type of tyres you use can also affect your electric car's range. Low-rolling-resistance tyres are designed to reduce friction and improve efficiency, which can help you drive further on a single charge.

Make the most of your EV battery

By following these tips, you can help extend your EV battery life and get the most out of your investment. Remember to take care of your battery, avoid fast charging, and keep it at a moderate temperature, and you'll enjoy years of eco-friendly, cost-effective driving.
