Abstract
A system includes a traction battery and a controller. The traction battery includes first and second arrays of battery cells. The controller is programmed to implement first and second filters, such as first and second bar-delta filters, configured to respectively generate output indicative of a state-of-charge (SOC) of the first and second arrays from models of the first and second arrays. The controller is further programmed to charge and/or discharge the traction battery according to power limits defined by the SOC of the first and second arrays.
Claims10
A system comprising:
- a single traction battery pack including a plurality of arrays of battery cells disposed within an enclosure of the traction battery pack and electrically connected to one another within the enclosure of the traction battery pack, each array of the traction battery pack including a group of the battery cells with a first group of the battery cells being arranged in a first array of the traction battery pack and a second group of the battery cells being arranged in a second array of the traction battery pack, the traction battery pack being connected to an electric machine;
- and
- a controller programmed to, while the traction battery pack is connected to the electric machine,
- implement first and second bar-delta filters configured to respectively generate output indicative of a state-of-charge (SOC) of the first and second arrays from models of the first and second arrays, and
- charge and/or discharge the traction battery pack according to the SOC of the first and second arrays.
