Abstract
A system and method is provided for determining a target state of charge (SOC) to charge a storage battery in an electric vehicle using electric power from an external power source. Charging the storage battery to the target SOC occurs prior to starting a drive cycle of the vehicle. The target SOC is determined based on a profile of regenerative braking energy expected to be recovered and a profile of energy expected to be used from the battery during a portion of a future drive cycle.

A method of charging a battery in a vehicle prior to beginning a drive cycle, the method comprising:
- controlling, by a controller, battery charging from a power source external to the vehicle based on a profile of regenerative braking energy expected to be recovered during a portion of a future drive cycle of the vehicle and a profile of energy expected to be used from the battery during the portion of the future drive cycle.
A method of charging a battery in an electric vehicle using electric power from a power source external to the electric vehicle, the method comprising:
- controlling, by a controller, prior to a drive cycle, charging of the battery to a target state of charge based on a profile of regenerative braking energy expected to be recovered during a portion of a future drive cycle of the electric vehicle and a profile of energy expected to be used from the battery during the portion of the future drive cycle.
A system comprising:
- at least one logic device configured to charge a storage battery in a vehicle prior to starting a drive cycle of the vehicle using electric power from a power source external to the vehicle to a target state of charge based on a profile of regenerative braking energy expected to be recovered during a portion of a future drive cycle of the vehicle and a profile of energy expected to be used from the battery during the portion of the future drive cycle.
