There are primarily four types of EV charging, distinguished by the speed at which they can charge an EV battery:
1. Slow charging (3-6 kW):
This is the most basic type of charging, often used for overnight charging at home. Slow chargers typically deliver up to 3-6 kW power, fully charging an EV battery in 6-12 hours. Slow charging can be carried out using a standard plug socket, however, for optimised charging, it is recommended that a dedicated charging unit is installed by a dedicated installer.
2. Fast charging (7-22 kW):
Fast charging delivers a power output between 7 kW and 22 kW, charging an EV in 3-4 hours. You can typically find these chargers in public car parks and workplaces. A dedicated circuit is needed for this level of charging, requiring professional installation.
3. Rapid charging (43 kW AC and 50-100 kW DC):
Taking the lead from fast chargers, rapid chargers provide power output from 50 kW to 100kW, and depending on the EV model and battery capacity, can charge an EV up to 80% in just 20-30 minutes.
4. Ultra-rapid charging (100+ kW DC):
Ultra-rapid charging delivers power above 100 kW to 350 kW. For vehicles that accept 100 kW or more, these powerful stations can charge a battery from 20% to 80% in roughly 20 minutes. If an EV isn’t capable of accepting over 50 kW, these charge points can still be used, but the power will be restricted to the level the vehicle can handle.
