Introduction of smart fortwo electric drive (3rd Generation) • Model Series 451
The charger feed-in socket (charge socket) is
located on the right rear B-pillar under a flap.
The socket is fitted with a folding protective
cover. Different versions are installed depending
on the national version of the vehicle (ECE,
USA/Canada).
ECE version
The 7-pin socket has 5 high-voltage contacts (L1,
L2, L3, N and PE) for the alternating voltage feed
and 2 signal contacts for Control Pilot (CP) and
Proximity (PP). The CP contact is used for data
exchange with the charging station and the PP
contact allows the vehicle to detect when the
charging cable is plugged in. On vehicles with the
3 kW on-board charger, only high-voltage
contacts L1, N and PE are used. There are 2 indi-
cator lamps above the socket which indicate
locking of the charging connector and the status
of the charging process.
