Electrical circuit based voltage control of electric vehicle batteries

A method, comprising:

• connecting a contactor of an electric vehicle to a first driver and a second driver;
• energizing, by a set of power supplies of the electric vehicle, the first driver and the second driver to cause the contactor to connect a voltage from a battery of the electric vehicle to a plurality of parts of the electric vehicle;
• receiving, by a switch, an indication corresponding to actuation of an emergency safety feature of the electric vehicle;
• and
• causing, by the switch in response to the indication, an electric circuit to disconnect the first driver from the set of power supplies to reduce the voltage from the battery to a first subset of the plurality of parts below a threshold voltage, while maintaining, by the electric circuit, the voltage from the battery to a second subset of the plurality of parts.

An electric vehicle comprising:

• a contactor of the electric vehicle connected to a first driver and a second driver;
• a set of power supplies of the electric vehicle to energize the first driver and the second driver to cause the contactor to connect a voltage from a battery of the electric vehicle to a plurality of parts of the electric vehicle;
• and
• a switch configured to, in response to an indication corresponding to actuation of an emergency safety feature of the electric vehicle, cause disconnection of the first driver from the set of power supplies to reduce the voltage from the battery to a first subset of the plurality of parts below a threshold voltage, while maintaining the voltage from the battery to a second subset of the plurality of parts.
