    摘要： [Subject Matter]
    To provide a vehicle power supply device capable of balancing the upper battery and the lower battery.
    [Solution(s)]
    The vehicle power supply device has an upper battery E1 on the high voltage side, a lower battery E2 connected to the earth side, a connection point CP between the upper and lower batteries, and FET 1 and FET 2 that supply electric power to the upper and lower batteries E1 and E2 by PID control 50. And furthermore, a feedback control 60 with a longer time than the I (integral control) 38 of the PID control 50 is added.

    摘要： The invention relates to an electronically controlled door latch (1) for a motor vehicle (2), the electronically controlled door latch (1) being configured for operating in at least three different operation conditions including a normal operating condition, a sleep operating condition and a crash operating condition, and comprising
    a system basis chip (3) configured for receiving a main supply voltage (Vbatt) from a main power source (6) of the motor vehicle (2) during the normal operating condition and a backup supply voltage (Vsc) during the crash operating condition,
    an electric motor (4) configured for actuating the electronically controlled door latch (1) based on the main supply voltage (Vbatt) during the normal operating condition and on the backup supply voltage (Vsc) during the crash operating condition, and
    an electronic control unit (5) configured, when being triggered by the system basis chip (3), for falling asleep during the sleep operating condition and for being wakening up during the normal operating condition and the crash operating condition and configured for controlling the electric motor (4) during the normal operating condition and during the crash operating condition.

    摘要： An auxiliary power supply unit (1) includes an auxiliary power supply device (71) and a downstream power supply line group (72) connecting the auxiliary power supply device to motor units (13, 32). The auxiliary power supply device (71) includes: an auxiliary power supply (111) provided on a power supply path to assist with power supply from an external power supply (45) to the motor units; and a switching circuit (114) configured to switch the connection state of the auxiliary power supply to the power supply path. The connection state of the auxiliary power supply includes a boost state in which the auxiliary power supply is connected in series with the external power supply between the external power supply and the motor units. The downstream power supply line group (72) includes branch first downstream drive lines (161, 162) and branch second downstream drive lines (163, 164). Each of the upstream ends of the branch first downstream drive lines and the branch second downstream drive lines is connected to the power supply path at a position downstream of the auxiliary power supply.

    摘要： Embodiments of this application propose a low-voltage redundant power supply system, including: a high-voltage battery pack, configured to provide a first voltage and including a number of power supply units sequentially connected in series, each of the power supply units being at least one battery in the high-voltage battery pack or an equivalent power supply formed by connecting a number of batteries in series/parallel; and a relay array, with relays in the relay array connected to the power supply units in the high-voltage battery pack based on a specified connection relationship, where in at least one on/off state combination of the relay array, at least one power supply unit in the high-voltage battery pack is reused in a time-division manner to provide a second voltage to supply power to a low-voltage load; and the first voltage is higher than the second voltage. The system can resolve the problems of a conventional low-voltage power supply solution failing to implement active balancing for batteries and a redundant power supply function for a low-voltage load, thereby improving power supply reliability, and avoiding power derating of a high-voltage power system caused by an SoC imbalance of batteries.
