Battery charging
The smart battery management enables dynamic adjustments, such as setting the optimum
charging current or ensuring temperature-dependent charging voltage for all detected battery
modules with “Battery Control”.
Temperature-dependent charging voltage
By using “Battery Control” to measure the actual temperature directly inside the battery mod-
ule, charging can take place in a temperature-compensated manner. The operating life of the
installed accumulators is thereby sustainably extended. Setting additional charging parame-
ters is not necessary due to automatic detection.
An IU charging characteristic is the basis for charge regulation. This is a 2-level charging
process as depicted below.

Alternatively, in the event of communication cable interruptions between the charge and con-
trol unit and the battery module, the temperature recorded in the charge and control unit can
also be used to guarantee temperature compensation.
Note:
Temperature compensation for battery modules without “Battery Control” is treated like a
communication interruption.
