  • Patent number: 12214673
    Abstract: Voltage control of electric vehicle batteries is provided. A system can include an electrical circuit of an electric vehicle that can include a plurality of power supplies and a driver component that can be configured to be energized by the plurality of power supplies and provide a voltage greater than a threshold from a battery of the electric vehicle to a motor of the electric vehicle. The electrical circuit can include a switch module that connects the driver component with the plurality of power supplies. The switch module can detect that the electric vehicle generated a signal to actuate an element of the electric vehicle and disconnect, in response to the detection, the driver component from the plurality of power supplies to reduce the voltage provided to the motor below the threshold.
