EV Charging Terminology

Backend refers to the software platform or server-side system that manages charger communication, user access, transactions and reporting. Often used as an accessible term alternative to CPMS. It is normally considered alongside charge point management systems, OCPP support, firmware updates, reporting and remote diagnostics.

Backend support means a charger can connect to a management platform for monitoring, control, data reporting or commercial operation. It is normally considered alongside charge point management systems, OCPP support, firmware updates, reporting and remote diagnostics.

Bidirectional charging allows energy to flow both into and out of an EV battery through compatible charging equipment. It is normally assessed alongside vehicle compatibility, export permissions, grid connection requirements and the supported communication standards.

Bluetooth is a short-range wireless technology used for local charger setup, commissioning or user control. It is normally considered alongside site connectivity, router/modem configuration, signal availability and ongoing remote support.

BS 7671 is the UK national standard for electrical installations, covering the design, erection, inspection, testing and verification of low-voltage electrical systems. Section 722 contains specific requirements for supplies to electric vehicles.

Built-in overcurrent protection means the charger includes internal protection against excessive current under specified conditions. It is normally assessed during product selection, circuit design, installation verification and maintenance of EV charging equipment.
