and a charge controller configured to, for a first charge cycle, initiate charging of the battery at a first start time identified from a defined charge complete time and a first energy estimate of non-charging loads, and, for a next charge cycle and same defined charge complete time, initiate charging of the battery at a next start time, later than the first start time, identified from the same defined charge complete time and actual energy consumed by the non-charging loads during the first charge cycle, wherein the non-charging loads include loads created by parameters external to the battery during the first charge cycle. ### Claim 2 (depends on 1) The vehicle system of claim 1, wherein the charge controller is further configured to charge the battery for the first charge cycle at a first rate identified from the defined charge complete time, and charge the battery for the next charge cycle at a next rate, different than the first rate, identified from the same defined charge complete time and the actual energy consumed. ### Claim 3 (depends on 1) The vehicle system of claim 1, wherein the charging during the first and next charge cycles is performed at a same rate. ### Claim 4 (depends on 1) The vehicle system of claim 1, wherein the charge controller is further configured to identify the first and next start times based on ambient temperature or humidity. ### Claim 5 (depends on 1) The vehicle system of claim 1, wherein the charge controller is further configured to identify the first and next start times based on calendar date or time of day. ### Claim 6 (depends on 1) The vehicle system of claim 1, wherein the charge controller is further configured to identify the first and next start times based on available charging power, a measured traction battery state-of-charge (SOC), a measured auxiliary battery SOC, or a target traction battery SOC. ### Claim 7 A method comprising: by a controller, for a first charge cycle, charging a battery at a first start time identified from a predefined complete time, and, for a next charge cycle and same predefined complete time as the first charge cycle, charging the battery at a next start time, later than the first start time, identified from the same predefined complete time and actual energy consumed by non-charging loads during the first charge cycle, wherein the non-charging loads include loads created by parameters external to the battery during the first charge cycle. ### Claim 8 (depends on 7) The method of claim 7, wherein the charging for the first charge cycle is at a first rate identified from the predefined complete time, and the charging for the next charge cycle is at a next rate, less than the first rate, identified from the same predefined complete time and the actual energy consumed. ### Claim 9 (depends on 7) The method of claim 7, wherein the charging during the first and next charge cycles is performed at a same rate. ### Claim 10 (depends on 7) The method of claim 7, wherein the charging during the charge first cycle is at a first rate and the charging during the next charge cycle is at a next rate, greater than the first rate. ### Claim 11 (depends on 7) The method of claim 7, wherein the first and next start times are further identified based on ambient temperature or humidity. ### Claim 12 (depends on 7) The method of claim 7, wherein the first and next start times are further identified based on calendar season or period of day. ### Claim 13 (depends on 7) The method of claim 7, wherein the first and next start times are further identified based on available charging power, a measured traction battery state-of-charge (SOC), a measured auxiliary battery SOC, or a target traction battery SOC.
