Electric Vehicle Batteries

Understanding EV batteries and their lifespans.

How do EV batteries work?

Similar to mobile phones, electric vehicles use lithium-ion batteries. Lithium-ion batteries are rechargeable with a power supply connection, which allows it to replenish its power. Once an EVs battery has charged, it uses the energy to power the EV motor and wheels.


EV Battery Lifespan

Electric vehicle batteries tend to have a warranty of 8 years, and some EV batteries can last up to 10 years before a replacement is necessary.

EV batteries degrade through charging cycles over time, and there is plenty you can do to protect your battery’s life span. 

Protecting your EV's battery

Prevent Overcharging

Never let your battery go down to 100% completely, and try not to charge over 80% on a regular basis.

Overnight Charging

Fast charging is not always the best solution. If possible, charging overnight with a 7kW EV charger can protect your battery. 

Mindful Acceleration

Practice smooth acceleration after a stop. Taking off after a stop too quickly and harshly makes an impact on your battery’s lifespan.

Learning about EV batteries can help reduce your range anxiety. As battery capacity increases, range concerns will disappear.

EV battery (lithium-ion) capacity is measured in kWh. Most EVs have a 40kWh capacity, but 100kWh is on the way. Battery kWh is related directly to EV range.

The higher the kWh of an EV the more miles you get on a full battery. For example, if an EV has a 40kWh battery it can travel 168 miles when charged completely.
