of the high-voltage battery is further
optimized. Incorrect calculation of the
state of charge is avoided
•
At-home charging is improved. Stability
during charging is improved and the timer
charging function is further optimized.
•
The calculation of the battery capacity is
optimized further
•
Home charging with third-party charging
equipment is improved. Discharge of the
12-volt vehicle electrical system battery
during charging is prevented.
•
The Charging Planner functions are
extended. For example, it is now possible
to set the charge level at which your
