Abstract
A battery includes a plurality of battery cells connected in series between a positive terminal and a negative terminal and a resistor connected in series with the battery cells. The battery also includes a plurality of cell voltage detection units which each include a plurality of voltage measurement inputs connected to a respective group of the battery cells. The battery is configured to determine cell voltages of the battery cells connected to the respective cell voltage detection unit. The cell voltage detection units are connected to each other by a communication bus and are configured to transmit, via the communication bus, the determined cell voltages to a microcontroller which is galvanically decoupled from the cell voltage detection units by an electrical isolation device. The resistor includes a first connection connected to a selected voltage measurement input of one of the cell voltage detection units.
