Abstract:
A method for determining an internal ohmic resistance of a first battery module includes measuring a first voltage intensity of the first battery module. The first battery module is connected to at least a second battery module. The at least second battery module is under a load current. A second voltage intensity of the first battery module is measured. The first battery module is disconnected from the at least second battery module to enable the measurement of the first voltage intensity and the connection of the first battery module.
