BATTERY ASSEMBLY WITH CONTROLLABLE VOLTAGE AND METHOD RELATED THERETO

A battery assembly and a control unit for aiming at outputting a target voltage during charging or discharging and a method, a battery assembly and a control unit for maintaining a target voltage of a battery assembly during charging or discharging are disclosed. The battery assembly () comprises a first battery module () configured to receive a first signal representing a first voltage to be output over the first battery module (), wherein the first signal is configurable to represent a range of voltages capable of being output over the first battery module (). Moreover, the battery assembly () comprises a plurality of second battery modules (-). Each second battery module () of the plurality of second battery modules (-) is configured to receive a respective second signal, representing a respective configuration, which indicates whether said each second battery module () is to be switched-on or bypassed.
