The best car charging station or EVSE (electric vehicle supply equipment) for your home depends on several things. The type of plug-in vehicle you have, plans for future plug-in vehicles, garage layout, current electrical service and when you want to charge the vehicle.
Select Electric can help you decide things like the size of the circuit and costs involved with the installation of the car charging station. The EVSE is a vital piece of the charging system. It is a communications and safety device. It provides a point for anchoring the charging cord between the car's onboard charger and the building's electrical service. It also controls the charging current to keep the car's batteries from overheating. It can shut down the charging in the event of an electrical short, power surge, charging software meldtdown or any other malfunction. This will protect your vehicle as well as the charging station.
Level 1 and Level 2 chargers and connectors:
All electric vehicle manufacturers have standardized their charging equipment with the exception of Tesla. However, there is an adaptor for the Tesla. If you look into the J1772 (the standard nozzle connector) nozzle's open end, you will see five prongs with open centers, or ports. The top two are for carrying power. The large port in the bottom or 6 o'clock position is the grounding port. The smaller one in the 4 o'clock position is the communications port. The fifth port, in the 8 o'clock position, is the safety systems port.
