IT Home April 12 news, the State Intellectual Property Office information shows that today, Xiaomi Automobile Technology Co., Ltd. announced the "electric vehicle and its control power circuit" patent. The patent application was filed on February 21 this year under the publication number CN114337263A.
IT House understands that the patent abstract shows that the application provides an electric vehicle and its control power circuit, which belongs to the field of electronic technology. It ensures that in the event of a low-voltage battery failure, it will still operate normally under low-side loads and high-side loads.
Control power circuitry is used in electric vehicles that include low-side loads and high-side loads.
The control circuit in the control power supply circuit can provide a low-voltage battery supply voltage within the voltage range, that is, when the low-voltage battery does not fail, the control first control power supply circuit is based on the supply voltage provided by the low-voltage battery to supply power to the low-side load, and the control of the second control power circuit based on the supply voltage provided by the high-voltage battery to the high-voltage side load power supply.
The control circuit can provide the supply voltage of the low-voltage battery outside the voltage range, that is, when the low-voltage battery fails, the control of the first control power supply circuit and the second control power supply circuit are based on the supply voltage provided by the high-voltage battery to the low-voltage side load and the high-voltage side load respectively.
