On average, a car battery can maintain about 5amps for ten hours. That makes such a battery a 50amp hour battery. That is equal to around 600-watt hours. If you take the 20-hour rate, then the battery might give you about 2.7amps.

An electric vehicle's battery capacity is measured in kilowatt-hours (kWh), the same unit your home electric meter records to determine your monthly electric bill.

Watts is amps x volts. So if you have say a 600CCA (cold cranking amps) car battery, then it can provide about 600amps x 12volts = 7200 watts for a few seconds needed to start the car. But how much power can it actually store?

This is a measure of how much power they need to be continuously supplied with in order to run. Letâ€™s say you have an electric motor rated at 200 kilowatts (kW) at peak power output.

Therefore, a new 40kWh battery in 2016 would have cost just shy of Â£10,000. Some predictions estimate that prices are set to fall below \$100/kWh by 2030, around the same time as the government are aiming for 50% of all new vehicles sold in the UK will be electric.

While a battery's kilowatt-hour help to determine the distance you can travel on one charge, it's important to remember that an electric car's management system prevents the vehicle from doing ...

The 300-volt, 50-kilowatt controller for this electric car is the box marked "U.S. Electricar." In this car, the controller takes in 300 volts DC from the battery pack. It converts it into a maximum of 240 volts AC, three-phase, to send to the motor.
