Patent number: 11498443Abstract: A system comprises an EVSE and an electric vehicle having a precharge mode. To charge a battery, the vehicle is connected to the EVSE. In some cases, the battery is unable to energize power buses. For example, if the battery is too cold and has insufficient charge, then the battery will not energize the power buses. If the battery cannot energize the power buses, then a precharge mode is enabled. During the precharge mode, charge is pumped onto two power buses until a setpoint voltage is reached. For example, a precharge circuit pumps charge onto one power bus and a power converter pumps charge from that bus onto a second bus. Once the setpoint voltage is reached, a current source charger is enabled, and energy stored on both buses is used to facilitate the turn-on of the charger, the precharge mode is disabled, and the EVSE charges the battery.Type: GrantFiled: December 13, 2020Date of Patent: November 15, 2022Assignee: Motiv Power Systems, Inc.Inventors: Sowmya Akella, James Michael Castelaz, Venkatesh Prasad Hanglur Narasimha, Joshua Sealand

Patent number: 11465575Abstract: An increase in the capacity of a power storage unit is effectively suppressed. An in-vehicle backup power source control apparatus includes a discharge unit, a control unit, and a temperature obtaining unit. The control unit controls a discharge operation such that an output voltage of the discharge unit reaches a target voltage. The temperature obtaining unit obtains the temperature of a power storage unit. When the temperature obtained by the temperature obtaining unit is within a predetermined first temperature range, the control unit sets the target voltage to a first target voltage, and when the temperature obtained by the temperature obtaining unit is within a predetermined second temperature range that is higher than the first temperature range, the control unit sets the target voltage to a second target voltage that is higher than first target voltage.Type: GrantFiled: August 1, 2019Date of Patent: October 11, 2022Assignees: AutoNetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventors: Hisanori Kambara, Yuuki Sugisawa
