摘要： A method includes implementing an inverted degradation model to determine an optimal battery core temperature. The inverted degradation model receives as inputs one or more of a power state value indicating whether the battery is currently in a high-power state or a low power state, a battery temperature value representing a current battery core temperature, a battery degradation value representing a battery degradation status, a battery age indicator representing a current age of the battery, a state of charge value representing a remaining battery charge and a battery current load value representing a current draw from the battery by the electric vehicle. The inverted degradation model outputs a desired battery core temperature value. The method includes operating the battery thermal system in order to achieve the desired battery core temperature.

摘要： A power supply system includes a power conversion circuit that is connectable to a power storage unit. The power supply system includes a control unit and a heat transferring unit. The control unit supplies a current between the power storage unit and the power conversion circuit by performing on-off control of a switch that configures the power conversion circuit. The heat transferring unit absorbs heat that is generated in the power conversion circuit in accompaniment with the on-off control of the switch and transfers the heat to a temperature-increase target element. The control unit performs temperature-increase mode control in which the switch is on-off controlled such that an amount of heat that is generated in the power conversion circuit is increased when a temperature-increase request for the temperature-increase target element is present, compared to when the temperature-increase request is not present.
