CHAdeMO

The Japanese DC fast-charging standard, with its own connector and CAN-based communication rather than power-line signalling. It was the first widespread DC system and natively supports bidirectional charging, but in Europe and North America it has given way to CCS.

Control pilot

The signal wire in an AC or CCS charging connector: the charger puts a ±12 V square wave on it whose duty cycle tells the vehicle the maximum current, and the vehicle answers by switching resistors. The proximity pilot beside it tells the vehicle a plug is inserted.

DC fast charging

Charging from a station that supplies DC straight to the pack, bypassing the car’s onboard charger, at 50 kW to over 350 kW. The BMS, not the charger, sets the current from moment to moment, which is why the charge curve tapers as the pack fills.

ISO 15118

The communication standard between an electric vehicle and a charging station: identification, authorisation, charge scheduling and, in the −20 edition, bidirectional power transfer. It is what lets a car authenticate itself and start charging with no card or app.

NACS

The compact AC and DC connector introduced by Tesla and standardised as SAE J3400, now adopted by most carmakers in North America in place of the CCS1 plug. The communication underneath is the same as CCS.

Onboard charger

The converter inside the vehicle that turns AC from a home or public socket into DC for the pack, typically rated 7–22 kW. DC fast chargers bypass it, which is why they can be so much more powerful.
