Abstract
A method is provided. The method is executable by a processor of a battery management system. The method includes sending a first command signal to a multiplexer to cause the multiplexer to select a cell of a battery. The method also includes sending a second command signal to a current source to apply a current to the cell of the battery. The method also includes receiving measurement information based on the application of the current to the cell from a measurement circuit.
Claims20
A method executable by a processor of a battery management system, the method comprising:
- sending, by the processor, a first command signal to a multiplexer to cause the multiplexer to select a cell of a battery;
- sending, by the processor, a second command signal to a current source to apply a current to the cell of the battery;
- and
- receiving, by the processor, measurement information based on the application of the current to the cell from a measurement circuit,
- wherein the measurement information comprises a cell voltage.
A battery management system comprising a processor configured to:
- send a first command signal to a multiplexer to cause the multiplexer to select a cell of a battery;
- send a second command signal to a current source to apply a current to the cell of the battery;
- and
- receive measurement information based on the application of the current to the cell from a measurement circuit.
A system comprising:
- a multiplexer configured to select a cell of a battery;
- a current source configured to apply a current to the cell of the battery;
- a measurement circuit configured to output measurement information based on the application of the current to the cell;
- and
- a microcontroller configured to control the operations of the multiplexer and current source via sending command signals.
