Abstract
A battery charger, which can be configured as a charger or docking station (300), includes one or more control circuits (105). A charging circuit (302) can charge one or more rechargeable batteries (118). A thermal management device (305) can alter a thermal condition of the one or more rechargeable batteries. The one or more control circuits can receive, with a communication circuit (309) an indication of a thermal state of an electronic device (100). The one or more control circuits can cause the thermal management device to alter the thermal condition of the one or more rechargeable batteries such that when the one or more rechargeable batteries are coupled to the electronic device, a thermal mass defined by the electronic device and the one or more rechargeable batteries transitions from the thermal state toward a predefined thermal mass temperature.
