One of the best things about owning an electric car is the ability to charge it in your own backyard. If you can charge your own car, you can avoid most of the hassle of charging on a public charging network, while saving money at the same time.
Your decision is quite simple. Home charging is a choice between L1 and L2 charging. Level 1 charging is simple, but also slow. If you decide that charging at a few kilometres of range per hour is simply not enough, L2 charging is the only option.
L2 mode charging
L2 charging is a method of connecting an electric vehicle to a standard AC mains socket using AC electric vehicle charging equipment with a cable and plug, with a control function and a personal electric shock protection system installed between the standard plug and the electric vehicle.
The current and voltage ratings for charging L2 shall not exceed:
32 A and 250 V AC – for single-phase connection,
32 A and 480 V AC – for three-phase connection.
Checking available power
Before deciding on the type of charging station, it is important to check the total connected power in the electricity network. The next step is to find out the energy consumption during peak load. This calculation is important because the charging station will be the biggest consumer in your home when it is in operation.
Example of calculation of available power for a three-phase connection:
Check the amperage of the main fuses (you can check this on your electricity bill) and multiply by 690 (3×230). Example: 20A x 690V = 13.8kW. Then subtract from this the maximum power you use during the scheduled charging period (most likely at night). Example: heat pump and washing machine = 5kW. This leaves you with about 8kW for your charging station. In this case, we recommend buying a charging station with a maximum power of up to 11kW.
Connecting to the network
The charging station must be connected to the mains using a dedicated cable equipped with its own fuse and a differential current protection switch. To connect a 16A charging station over a maximum distance of 100m, you need a connection cable with a minimum cross-section of 2.5mm2.
All of the charging stations in our range are in the 22kW range. Such charging stations not intended for public use and connecting to the low-voltage network downstream of an existing metering point do not require an additional Connection Consent.
Filling speed
The charging stations in our range offer a complete solution for charging electric vehicles at home or at your business premises. These chargers ensure safe and comfortable charging and give you full control of the system via a control app.
