You needn’t have written your thesis on electrolytes in order to understand how an electric car battery works. Size, unit of measure, energy consumption: these are the basics for understanding a battery’s machinery.

Have you always wanted to know how an electric car battery works, but been afraid to ask?  In reality, the operation of an electric car battery is similar to that of a smartphone. The size of the battery is simply proportional to the size of the object it powers.

The capacity of an electric car battery is given in kilowatt hours (kWh). For an electric vehicle’s consumption, we refer to kWh per 100 km. The relationship between the two is simple: the higher a battery’s capacity, the longer it takes to charge and the more the car’s range increases. It’s simply common sense!

An electric car battery’s energy consumption: between 12 and 20 kWh/100 km

Luckily, your electric car’s battery doesn’t run out as quickly as your smartphone’s! The average energy consumption of an electric car battery is between 12 and 20 kWh per 100 km travelled. So, for a Renault ZOE equipped with a Z.E. 40 battery, which has a capacity of 41 kWh, the range will be about 300 km.

Note, however, that the range may vary depending on your driving style. Adopting eco-driving techniques, in other words favouring smooth driving without sudden stops and starts, will significantly boost your range! There’s no need to blast off like a rocket as soon as the light turns green!
