A hybrid electric vehicle (HEV) and method of operation, which include a battery and a communication unit, which are configured to periodically respond to a charge signal, and to adjust a charge time and battery recharge profile, according to a charge time estimate received from a remote fleet server. The charge time estimate is received in response to periodic operating conditions that are generated and communicated to the server. The operating conditions include one or more of charge station, environment, and location data, vehicle data, and battery performance data, among other data. The controller further configured to respond to a charge complete signal, and to generate and store as one of the battery performance parameters, an estimate error as a difference between the charge time estimate and an actual charge time. The controller readjusts a charge time and battery recharge profile, responsive to the estimate error.
