Abstract
A wireless cell array tracker includes a daisy chain connecter and processor each supported on a circuit substrate. The circuit substrate is attached to a battery array. The daisy chain connector physically interfaces with a battery sensing module of the battery array. The processor retrieves data from the battery sensing module via the daisy chain connector, and commands wireless transmission of the data.
Claims19
A wireless cell array tracker for an automotive battery array, comprising:
- a circuit substrate carrying
- a transceiver,
- a daisy chain connector configured to physically interface with a battery sensing module of the battery array, wherein the battery sensing module is configured to measure data of cells of the battery array via sensors, confirm correct operation of the sensors, and apply an ohmic load to the cells for balancing, and
- a processor programmed to retrieve voltage data from the battery sensing module via the daisy chain connector, and transmit the voltage data via the transceiver.
A battery pack comprising:
- a cell array;
- a battery sensing module carried by the cell array, and configured to measure data of cells of the cell array via sensors and to apply an ohmic load to the cells for balancing;
- and
- a wireless cell array tracker carried by the cell array and including a daisy chain connector configured to physically interface with the battery sensing module.
