For speed of charging an electric vehicle, homeowners are considering to install a three-phase power supply to charge their car up to 22Kw instead of up to 7Kw on single phase. If this was the case, are there any safety precautions that need to be considered, by the homeowner, assuming that a power company would be supplying and connecting the three-phase power supply to a high-power electric vehicle charger?
Hi how are you ?
charging is the result of a charging station with low electrical power (about 3.5 kilowatts) while fast charging is possible when the charging station has a higher electrical power (on the range between 7 and 22 kilowatts).
All electric vehicles can be charged with slow and fast charging but not in all cars the connection to the same position.
When it comes to slow or fast charging, the connections in electric vehicles are divided into two groups:
Cars with a type 1 connection or type J1772.
Cars with a type 2 connection (type 2) which is sometimes called Mennekes.
The differences are in the form of the connection itself (think of the difference between a European socket and an American socket, for example) and in geography: for the most part, cars manufactured in the Far East and the United States have a Type 1 connection, while European vehicles have a Type 2 connection.
A type 1 connection looks like this:
A type 2 connection looks like this:
