Charging of high-voltage battery
NOTICE
When fast charging with direct current (DC), the charging proc-
ess is carried out using a very high charging current. Frequent
rapid charging (DC) can permanently reduce the charging ca-
pacity of the high-voltage battery.
Charge the high-voltage battery predominantly with alternat-
▶
ing current (AC) in the charging range of 7.2 to 11 kW.
NOTICE
Long periods with the vehicle left standing with a fully charged
high-voltage battery for several months can lead to a permanent
reduction in the charging capacity of the high-voltage battery.
Avoid prolonged vehicle downtimes when the high-voltage
▶
battery is at a high state of charge.
At very low and very high temperatures, there may be re-
strictions when charging the high-voltage battery. The charging
time may be longer.
As the state of charge of the high-voltage battery increases,
the ability of the high-voltage battery to absorb energy decrea-
ses. This slows down the charging process.
