  • Patent number: 11774507
    Abstract: A method for estimating a power limit of a battery pack is disclosed, including: obtaining an actual minimum cell voltage of an electrical core with a minimum voltage in the battery pack; obtaining a static discharge power limit of the battery pack; calculating, based on the actual minimum cell voltage, an estimated discharge voltage of the electrical core with the minimum voltage for use when the battery pack is discharged based on the static discharge power limit; determining whether the estimated discharge voltage falls between a discharge voltage control threshold of the electrical core with the minimum voltage and an undervoltage threshold of the electrical core with the minimum voltage; and determining a target discharge power limit of the battery pack through a discharge interpolation algorithm when the estimated discharge voltage falls between the discharge voltage control threshold and the undervoltage threshold.

  • Patent number: 11745615
    Abstract: A power system includes a charge circuit connecting a low voltage circuit to a high voltage circuit; a charge control unit configured to execute an auxiliary charge control to charge a low voltage battery; a BCM configured to accept an ON operation or an OFF operation; and an auxiliary charge timing setting unit configured to set an auxiliary charge timing at which the auxiliary charge control is to be executed during a standstill period, the standstill period starting from acceptance of the OFF operation and ending at acceptance of the ON operation. If a soak time is shorter than an auxiliary charge-allowing period, the charge control unit executes the auxiliary charge control at the auxiliary charge timing set by the auxiliary charge timing setting unit, whereas if the soak time is longer than the auxiliary charge-allowing period, the charge control unit does not execute the auxiliary charge control.

  • Patent number: 11738657
    Abstract: A vehicle includes an electric-device temperature acquisition unit, a charging controller, and a predicted charging time deriving unit. The electric-device temperature acquisition unit acquires a temperature of an electric device disposed in a current path for external charging for supplying electric power from a power supply external to the vehicle to a battery mounted in the vehicle. The charging controller pauses a supply of electric power to the battery in response to the temperature of the electric device becoming greater than or equal to a first threshold during the external charging, and resumes the supply of electric power to the battery in response to the temperature of the electric device becoming less than a second threshold lower than the first threshold. The predicted charging time deriving unit derives a predicted charging time predicted to be taken for the external charging in accordance with an instruction for the external charging.

  • Patent number: 11731530
    Abstract: A 12 volt automotive battery system includes a first battery coupled to an electrical system, in which the first battery include a first battery chemistry, and a second battery coupled in parallel with the first battery and selectively coupled to the electrical system via a first switch, in which the second battery includes a second battery chemistry that has a higher coulombic efficiency than the first battery chemistry. The first switch couples the second battery to the electrical system during regenerative braking to enable the second battery to capture a majority of the power generated during regenerative braking. The 12 volt automotive battery system further includes a variable voltage alternator that outputs a first voltage during regenerative braking to charge the second battery and a second voltage otherwise, in which the first voltage is higher than the second voltage.

  • Patent number: 11697350
    Abstract: A hybrid powertrain system and method includes a prime mover driving a generator/motor to produce an AC power output. The AC power output is applied to a rectifier which is controlled to transform the applied AC power to DC power to supply a DC Power bus at a selected voltage and current. An energy storage device is also connected to the DC power bus and the current flow between the energy storage device and the DC power bus is monitored and compared to preselected values and the results of that comparison are used to alter the operation of the rectifier to increase or decrease, as needed, the current provided to the DC power bus as electrical loads on the DC power bus change.
