Firmware

EV charger firmware is embedded software stored on charge point hardware that controls how the device behaves and communicates. It can handle functions such as protocol messaging, hardware control, diagnostics and local configuration. Firmware sits close to the electronics, so an update can affect far more than the user interface. Changes can alter communications, security behaviour or how peripherals are controlled. Connected charge points therefore need a controlled firmware-update process. Version management, rollback planning and update authentication all affect field reliability.
