EV battery basics : All you Need to Know in 30 Secs
Batteries in modern lithium-ion-based electric vehicles aren't all that different, only much larger.
EV battery size is measured in kWh,
A kilowatt-hour is a measure of the energy consumed by a device when it operates for one hour. It is not the number of kilowatts used per hour.
You want one with a large kWh rating as this will be able to power the car for the most amount of time.
The downside of large EV batteries is that they take longer to charge when powered from a standard outlet.
However, EVs with larger batteries typically support faster charging standards as well. .
