HOW TO INSTALL A CHARGING STATION FOR AN ELECTRIC VEHICLE?

A IRVE certified installer

To install your charging station, We need a certified professional electrician (Recharge Infrastructures for Electric Vehicles). Wallbox already works with a network of certified electricians, accessible here . More and more electricians are certified, and the simplest is often buying the terminal of your choice on our site , then ask the licensed electrician of your choice to install it near you.

B Checking Available Power

It is important to check the total power of your electrical installation, and to deduce the maximum power consumption during peak consumption. You will then get the available power that will power your terminal. This step is important because the terminal will surely be the element that will consume the most in your home: a terminal of 11kW is equivalent to 11 small electric heaters. If the power is insufficient, it will be necessary to ask your energy supplier an increase of this one.

Example of calculation of available power:

• Single Phase Installation: Look at the amperage of your main breaker, and multiply it by 230V. Ex: 40A x 230V = 9.2kW. Then deduce from this total the max power you consume in instantaneous. Ex: 3 electric radiators of 1kW, 1 microwave oven 1kW, 1 washing machine1kW, (lighting is negligible). So you have about 4kW left for your terminal.
• Three Phase Installation: Look at the amperage of your main breaker, and multiply it by 690 (3×230) V. Ex: 17A x 690V = 11.7kW. Then deduce from this total the max power you consume in instantaneous. Ex: 3 electric heaters of 1kW, 1 microwave oven 1kW, 1 washing machine 1kW (lighting is negligible). So you have about 7kW left for your terminal.

C Dedicated Line and Mandatory Electrical Protections

A charging station must be installed on a dedicated line, with its own breaker coupled with its own differential switch . A release with current release is additional security not required, but allows you to obtain ZE Ready certification. Below are the specifications of these elements to be in good standing:

• Single phase installation:
  • Differential switch : Type A Hi, 30mA, 2P or 1P + N, 40A max
  • Breaker : Min. C curve, 3kA min., 2P or 1P + N cutoff, 16 to 40A (choose 3 to 8A in addition to the rated current of the terminal)
  • Current-Release Triggers : No special specifications
• Three-phase installation:
  • Differential Switches : Type B, 30mA, 4P, 40A Max (One Type A is Enough , instead of type B, if the terminal is equipped with a DC leakage current detector, this is the case for terminals BESEN and DUOSIDA )
  • Breaker : Min. C curve, 3kA min., 2P or 1P + N cutoff, 16 to 40A (choose 3 to 8A in addition to the rated current of the terminal)
  • Current-Release Triggers : No special specifications

To make it easier for you to choose electrical protections, Wallbox already offers packs compatible terminals and protections .
