Charging options forth e high-voltage battery
(mode 2, 3 or 4):
R Charging through recuperation while theve hi-
cle is in motion
R Charging with alternating cur rent when sta-
tiona ry:
- at a mains soc ket (mode 2)
- at a wallbox or charging station (mode 3)
R Charging with direct cur rent when stationary
(vehicles with combo vehicle soc kets):
- at a fast charging station (mode 4)
Depending on the count ry-speci/c vehicle equip-
ment and your vehicle's charging cable, single
phase ACcharging is also possible.
