A monitoring device 10 for an at least partially electric vehicle comprises: a housing 14 arranged on the vehicle to accept high voltage input connections 22a, 22b; an access door 16 to provide access to a user interface; an electric circuit, for monitoring the presence of high voltage provided by the high voltage input connections; and a high voltage interlock protection circuit provided in the housing. A microcontroller controls the monitoring circuit, the high voltage interlock, and an indication on the user interface to display when high voltage is present. The access door may have a door switch to break continuity in the interlock when the door is opened. There may be first and second monitoring circuits for high voltage. If the first circuit indicates no voltage, the second circuit may be activated to confirm this. The absence of high voltage may thus be ensured before e.g. maintenance on the vehicle.
