Electric car battery is more expensive then combustion engine battery. Cause there`s a big difference. Therefore, a regular car battery doesn`t drive the car. Because, regular car battery starts the car and electric car battery drive the car.
The main different between regular car battery and electric car battery
- Size;
- Capacity;
- Purpose;
- Chemistry.
The main purpose of the battery for an electric car is using as the primary energy source for propulsion. It needs a high energy density. The regular battery is used to start an internal combustion engine provides a large amount of current for a short period and will be immediately recharged.
You would need 75 of the ICE car batteries to replace electric car battery.
The EV battery has a significantly higher power capacity to give both a higher voltage and greater power over sustained periods.
A regular car battery is about 500 watt-hours in comparison with an electric car battery, which has up to 100,000 w hours. This 24kW battery is near $3,600.
What is really only thing for these batteries is that they are batteries. However, they are incompatible and incomparable.
