Abstract
A vehicle system includes a battery, and a charge controller configured to, for a first 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 cycle.
Claims13
A vehicle system comprising:
- a battery;
- 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.
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.
