- CHAdeMO – One of three DC Quick Charge “standards.” Currently used by Nissan, Mitsubishi and KIA.
- Charger – A charger converts AC supply power to DC and uses it to charge the vehicle batteries. Modern plug-ins have their own on-board charger. This can be it’s own discrete unit, or the electronics can be integrated into the drivetrain or another component. Chargers can also exist off the vehicle, as in the case of DC quick chargers. Note: Although the Level 1 cordset that comes with every PEV and Level 2 units are commonly referred to as “chargers” they are not actually chargers. They are actually “Electric Vehicle Supply Equipment (EVSE.)”
- DC Quick Charger – An offboard charger that connects directly to a vehicle’s high-voltage battery. Allows for high power transfer and can charge a battery to 80% or so in minutes instead of hours. Quick charging should be done according to vehicle manufacturers specifications, as this charge method can be damaging to the battery if done too often.
- Electric Vehicle Supply Equipment (EVSE) – Not to be confused with chargers, this term refers to any off-board equipment used to supply charging energy to the vehicle. EVSE can’take the form of a cord, a station mounted to a wall, pedestal or pole, and even the different outlets and plugs that make up the circuit. This equipment should prevent energizing of the charge plug until it is seated in a vehicle port. It should monitor for safety hazards. It communicates to the vehicle the amount of current that can be provided by the circuit and gets information about area ventilation requirements.
- Nationally Recognized Testing Laboratory (NRTL) – Testing facility that provide product safety testing and certification services to manufacturers.
- SAE J-1772 – A Society of Automotive Engineers (SAE) standard that covers AC Level 1 and 2 and DC Level 1 and 2 charging. J-1772 is the standard for AC charging in the United States. The latest revision was published in October of 2012.
