I'm very interested in this subject.
I read about Coulomb Tech. that owns such product and wanted to ask something about it please.
Each Charging Station comprises a RFID reader (Smart Card Reader), as part of the authentication process of allowing only permitted cars to use the Charging Station for charging.
Is this Smart Card installed on the car itself, meaning the car itself is being autherized, or is the Smart Card given to the driver, which will allow the driver to charge any vehicle he desires (not only his own vehicle).
Yeah, but if the Charging Station authorizes the driver, and not the vehicle, then a driver who receives such vehicle from the company he works for (for example) could use the card in order to charge its private vehicle.
There are two charge levels on the right column: the low level uses only the 120V/16A line (level 1: 1.9kW). The higher level 2 uses a 208/240V@30A three phase power for 7.2kW charge power. The 120V uses two wires (line and neutral) and the 240V three phase uses two lines and neutral. Total of five wires: Line(120), Line (240), Line (240), neutral, earth ground. Each 240Line is rated for 30A, the 120 Line is 16A.
You would use slow charge if you have the time and fast charge only if you must. fast charge will likely be less efficient because it pushes the power converter harder. It also increases peak power usage.
