Claims17
A vehicle system, comprising:
- a battery pack;
- and
- a controller configured to charge and discharge the battery pack based on a power capability of the battery pack defined using a modified open circuit voltage (OCV) adjusted based on a nominal OCV and a voltage differential between a measured terminal voltage and a modeled terminal voltage, the power capability being different from a nominal power capability defined during an electric current pulse using the nominal OCV at the time of the electric current pulse.
A vehicle system comprising:
- a battery pack;
- and
- a controller configured to charge the battery pack based on a power capability of the battery pack defined using a modified open circuit voltage (OCV) adjusted based on a voltage differential between a measured voltage and a modeled voltage.
A control system for an electrified vehicle having a battery pack, comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium comprising programming instructions that are configured to cause the processor to implement a battery control method, wherein the programming instructions comprise instructions to:
- discharge the battery pack according to a power capability that is defined using a modified open circuit voltage (OCV) that is adjusted according to a differential between a measured voltage and a modeled voltage.
