The big difference is whether you have a Hybrid or 100% electric car. A Hybrid car will have a charging capacity of 3.7kW or 7.4kW (1-phase, with the exception of some cars even 2-phase) and a fully electric car will have a charging capacity of 11kW or 22kW (3-phase).
To find out what charging capacity your car has you can use our car brands page. Choose your brand, select the correct model and at the bottom of the page you will find the charging capacity of your electric or hybrid car.
