Abstract
An apparatus for a vehicle may comprise a processor and a memory storing at least one instruction that, when executed by the processor communicating with the memory, is configured to cause the apparatus to determine, via at least one sensor of the vehicle and based on a state of health (SOH) of a battery of the vehicle, a degradation state of the battery, output a signal indicating the determined degradation state of the battery, and control, based on the signal, at least one of charging or discharging of the battery by expanding at least one of a charge prohibition region or a discharge prohibition region of a state of charge (SOC) control strategy of the battery.
Claims20
An apparatus for a vehicle, the apparatus comprising:
- a processor;
- and
- a memory storing at least one instruction that, when executed by the processor communicating with the memory, is configured to cause the apparatus to:
- determine, via at least one sensor of the vehicle and based on a state of health (SOH) of a battery of the vehicle, a degradation state of the battery,
- output a signal indicating the determined degradation state of the battery, and
- control, based on the signal, at least one of charging or discharging of the battery by expanding at least one of a charge prohibition region or a discharge prohibition region of a state of charge (SOC) control strategy of the battery.
A method performed by an apparatus, the method comprising:
- determining, via at least one sensor and based on a state of health (SOH) of a battery, a degradation state of the battery;
- outputting a signal indicating the determined degradation state of the battery;
- modifying, based on the signal, a state of charge (SOC) control strategy by expanding at least one of a charge prohibition region or a discharge prohibition region of the SOC control strategy;
- and
- controlling, based on the modified SOC control strategy, at least one of charging or discharging of the battery.
A vehicle comprising:
- a battery of the vehicle;
- at least one sensor configured to detect at least one of a voltage, a current, or a temperature of the battery;
- a processor;
- and
- a memory storing at least one instruction that, when executed by the processor communicating with the memory, is configured to cause the vehicle to:
- determine, based on data from the at least one sensor, a state of health (SOH) of the battery,
- expand, based on the determined SOH, at least one of a charge prohibition region associated with state of charge (SOC) control of the battery or a discharge prohibition region associated with SOC control of the battery, and
- control, based on the expanded charge prohibition region, charging of the battery or control, based on the expanded discharge prohibition region, discharging of the battery.
