What You Need to Bear in Mind When Installing a Charging Station at Home. We Have Put the Most Important Tips Together for You.
When installing a charging station for your electric car, consideration must be given to various safety criteria. Our check-list includes all the key points you need to remember when installing your charging station. For electricians and specialists, we have also created an electricians’ check-list , based on the technical requirements defined in the German standard DIN VDE 0100-722.
Two Components Needed for Installing a Charging Station:
Select your charging station model from the table and we will show you which residual current device and circuit breaker you need for the fuse box.
|Charging station model||RCD||Circuit breaker|
|Charging station without integrated RCD or DC fault current sensor (e.g. KEBA P20)||RCD type A EV||Characteristic C|
|Charging station with integrated DC fault current sensor (e.g. KEBA P30)||RCD type A||Characteristic C|
|Charging station with RCD type A and DC fault current sensor (e.g. ABL)||-||Characteristic C|
You may also require a separate electricity meter if you wish to measure the charge received by the electric car and the charging station does not already have its own meter, or a Z.E. READY certified charging station for Renault electric cars.
Six Points Which Have to Be Complied With When Installing a Charging Station:
The Charging Station Must Be Connected Via Its Own Cable.
No additional appliances should be connected to the cable leading from the fuse box to the charging station. Further appliances would include e.g. garage sockets, lights, washing machine.
For charging stations, a simultaneity factor of 1.0 applies. The simultaneity factor takes account of the fact that not all devices within a system are operated at the same time or at full power For charging stations, however, this is exactly what must be assumed. The connected load of the charging station must therefore be 100% respected.
The Cables Must Be Of Appropriate Dimensions For The Connected Load Required.
If cables are too thin, they become hot, and there is a danger of the cables burning. If the charging current is of 16 A or above we recommend a cable diameter of 2.5 mm2 or more. In order that the vehicle can be charged with a charging power of 11-22 kW, and in three phases, a 5-conductor supply cable must be used.
The inner diameter of the cable depends on factors such as cable length, potential drop, environmental temperature and type of installation. It is therefore best to get a qualified electrician to determine what diameter cable you require. We recommend preparing cables where possible for a three-phase connection, in order to be future-proof. The electric cars of the future will have higher charging powers and larger battery capacities.
The Residual Current Device (RCD) Avoids Electric Shocks and Must Be Appropriate for the Charging Power of the Electric Car.ORDER NOW YOUR RCD
The Circuit Breaker (CB) Protects the Cable from Being Overloaded by Excessive Currents, Must it Correspond to the Charging Power of the Electric Car.
When Installing a Charging Station with a Charging Power of Over 12 kW, You or Your Electrician Must Obtain Approval from the Grid Operator.
When charging power is over 12 kW, an electric car will draw an unusually large amount of power at one time from the power grid. Therefore the grid operator should be informed, in order to avoid power outages. The approval process varies from operator to operator. Our best advice is to make a quick phone call to the grid operator and ask them to send you the necessary documents.
