All high-end electric cars have two batteries. Automakers are pouring money into battery technologies in order to increase the range and capability of future electric vehicles. If you open the bonnet of a modern electric car, you will find a standard 12-volt automobile battery with the high voltage main battery.
An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.
Two types of batteries are used in electric vehicles – lithium-ion batteries and lead acid batteries. The lithium-ion battery is used to power up the engine, and it is the larger battery. It is located on the floor inside of the vehicle, and because of that, that configuration of the car is called the skateboard.
All electric car batteries have a usable capacity that's slightly less than the total capacity because this helps extend the life of the battery pack since that buffer prevents it from ever being completely charged. For example, the BMW iX's battery pack has a total capacity of 111.5 kWh, but its usable capacity is 106.3 kWh.
The majority of electric vehicles are powered by a lithium-ion battery pack, the same type of battery that powers common electronic devices like laptop computers and cellphones. However, the units powering EVs are massive and usually span the area of the vehicle's floor between the front and rear wheels.
We wrote a separate article about electric cars and backup batteries. Electric cars don’t have backup battery packs to take you further in case you run out of power. This would be too expensive and also add unnecessary weight to the vehicle. What are the reasons for using two batteries in electric cars?

How do Electric Vehicles, Cars Work
Battery Electric Vehicles (BEVs): These battery powered vehicles are all-electric cars that are powered exclusively by electr i city. BEVs need to be plugged into an outlet or charging station to recharge. This type doesn''t use petrol or diesel to run so doesn''t produce any emissions like traditional cars. The information on this page will mostly relate to this type of EV.
