CAN bus

The serial network over which a BMS talks to the vehicle or inverter: a two-wire differential bus, defined in ISO 11898, carrying short prioritised messages at up to 1 Mbit/s, or faster with CAN FD. Every node hears every message, and a dominant bit wins arbitration without any collision.

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.

DIN 70121

The German specification for the digital communication between an electric vehicle and a DC charger in the Combined Charging System, the forerunner of ISO 15118. Most DC chargers in Europe still speak it, so vehicles support both.

EVCC and SECC

The two ends of high-level charging communication: the electric vehicle communication controller in the vehicle and the supply equipment communication controller in the charger. They exchange limits, schedules and authorisation over power-line communication on the control-pilot wire.

ISO 17409

The standard for the safety of a vehicle’s conductive connection to an external electric power supply — charging. It sets the electrical-safety requirements the vehicle side of an AC or DC charging connection must meet.

Vehicle-to-grid

Discharging a vehicle’s battery back into a house or the grid through a bidirectional charger, so parked cars act as storage. Vehicle-to-load and vehicle-to-home are the simpler forms that power appliances or a house directly.
