Vice versa, if the I01 was parked outside for example for several days at temperatures below 0 °C, it
makes sense to heat the battery cells before departure and/or to their optimal temperature level. They
then deliver their full power before the journey commences. The customer can use this option if the
vehicle is connected to the power network using the charging cable and the function for the interior
air temperature control of the vehicle was selected. In order to warm up the batteries, the high-voltage
system is activated and electrical current is sent through a network of heating wires.This network of
heating wires is arranged along the coolant ducts. As the coolant ducts and the cell modules touch,
the heat generated in the heater coils is transmitted to the cell modules and therefore the battery cells.
