| 摘要 |
The invention relates to a battery, comprising a plurality of battery cells connected in series between a positive terminal and a negative terminal, and comprising a plurality of cell voltage detection units (20-1,..., 20-n). Each cell voltage detection unit (20-1,..., 20-n) comprises a plurality of voltage measurement inputs connected to a respective group of the battery cells (10-1,..., 10-n) and is designed to determine cell voltages of the battery cells connected to the respective cell voltage detection unit (20-1,..., 20-n). The cell voltage detection units (20-1,..., 20-n) are connected to each other by a communication bus and furthermore are designed to transmit, via the communication bus, the determined cell voltages to a microcontroller (40), which is galvanically decoupled from the cell voltage detection units (20-1,..., 20-n) by an electrical isolation device (30). According to the invention, the battery comprises a resistor (50), which is connected in series to the battery cells and at least one first connection which is connected to a selected voltage measurement input of one of the cell voltage detection units (20-1,..., 20-n). The invention further relates to a motor vehicle comprising an electric drive motor for driving the motor vehicle, and to a battery according to the invention which is connected to the drive motor. |
