LED
LED lights up red when the interlock between plug and vehicle is
active.
A special feature of the CHAdeMO plug is an interlock button above the handle. After the
charging process ends, the button has to be pressed to remove the plug from the vehicle
inlet.
An LED (11) on the handle lights up when the interlock between plug and vehicle is active.
AC charging socket
The AC charging socket provides a third charging port on the charging station. The charging
socket was already described in detail in section 3.3 (Page 23).
Interlock
To guarantee secure charging, the charging plug and charging socket cannot be
disconnected under load. After plugging in and initiating the charging process, an
electromechanical actuator automatically locks the plug-in connection in the vehicle inlet or
the AC charging socket. The connection is released again when the charging process is
complete.
