Fast chargers are not as high-powered so not as quick as Rapid (or Ultra Rapid chargers). Fast chargers are AC powered and go up to 22kW in power, while Rapid chargers are DC powered and units start at 50kW and go up to 350kW. Not all cars can charge beyond 150kW.
To find out how quickly your EV can charge go to https://electrictogether.com/evs and select your car.
Note:
Your EV's battery capacity is measured in kilowatts (kW). EV charging speed is measured by the number of kilowatts (kWh) that are transferred from the electricity source to your EV’s battery, per hour. Therefore, a 50kWh charge point transfers more electricity into your battery during an hour than a 22kWh charge point.
