DYNAMIC TARGET STATE OF CHARGE FOR HYBRID VEHICLE CAPACITY ESTIMATION

A vehicle includes a system that performs a method of calculating a capacity of a battery of the vehicle. The system includes a processor configured to operate the vehicle to deplete the battery to reach a target low state of charge, measure a resting low state of charge after allowing the battery to rest for a first rest period after the battery reaches the target low state of charge, operate the vehicle to charge the battery to reach a target high state of charge, measure a resting high state of charge after allowing the batter to rest for a second rest period after the battery reaches the target high state of charge, and calculate the capacity of the battery from the resting low state of charge and the resting high state of charge.
