When you think of batteries, you probably imagine the things you used to stuff in the back of a portable radio or inside your watch. Modern lithium-ion-based electric car batteries aren’t too different, they’re just much, much bigger. EV battery size is measured in kWh, or kilowatt hours. But what is that? A kilowatt hour is.

AI Customer ServiceFor instance, consider a battery with a capacity of 50 kWh. If it’s charged at a 1C rate, it’s charged at a rate that fills the battery’s full capacity in one hour, so 50 kW. Charging at a higher rate, like 2C, would mean it charges in half the time, i.e., 30 minutes, with a power output of 100 kW.
Charging power, measured in kW, is critical when considering how long it will take to “refill” your electric vehicle. Charging stations can range from slow home chargers that might only deliver 2-7 kW, up to ultra-fast public charging stations that can deliver 350 kW.
A kilowatt refers to how much power a charger has in order to deliver the energy – essentially how quickly the charger can transfer energy to the car. The higher the kW power rating on a rapid charger, the faster the output of the charger to deliver the kWh.
Charging stations can range from slow home chargers that might only deliver 2-7 kW, up to ultra-fast public charging stations that can deliver 350 kW. Keep in mind that your EV’s onboard charger also has a maximum charging rate it can accept.
Let’s say we’re charging a 75 kWh EV from a 22 kW wall box. If the car’s battery was completely flat, it would take about 3.5 hours to fully charge — 75 divided by 22 equals 3.4. That’s assuming the charger works at peak power the whole time, which it probably won’t.
kWh (kilowatt hour) is a unit of energy and is used when talking about electric car battery capacity and the ‘amount’ of energy put into the battery from the charger. With so many different acronyms floating around when it comes to electric cars (BEV, PHEV, RFID, CCS – the list goes on!) it can start to get overwhelming.
