Functional description
The battery management electronics supply the cell supervision circuits with a supply voltage of 5 V. In addition, the cell supervision circuit can be directly supplied by the cell block. A cell supervision circuit monitors the state of the 12 lithium-ion batteries:
- Measuring and monitoring the voltage of each individual battery cell
- Measuring and monitoring the temperature at several points of the cell module
- Communication of measured variables to the battery management electronics (SME)
- Carrying out the adjustment process for the cell voltage of the battery cells
