NEVA has also supported EVITP to help train instructors for its workshop program, who are skilled in training electricians within the International Brotherhood of Electrical Workers (IBEW) about NEC considerations for EVSE installations.
There are competing standards based on a power source of 480 VAC, three-phase power that can provide 400 Volts DC with an electrical current delivering 100 Amps or more.
The Society of Automotive Engineers International has been working to define this standard as SAE J1772 DC Level 2 but has not finalized a universal configuration and protocol at this time.
The Nissan LEAF and Mitsubishi i-series electric cars both use just lithium-ion battery packs to store the electrical power they use to drive their vehicles’ electric motors for a range of 80 to 100 miles before they need to be recharged.
Both companies chose to use a standard DC Quick Charge system and connector protocol defined by the Tokyo Electric Power Company (TEPCO) as Chade Mo.
Both the connector plug on today’s electric vehicles as well as the EVSE provided by different automotive manufacturers and third party equipment suppliers are subject to standard specifications defined by the Society of Automotive Engineers (SAE) International.
