Vehicle collision safety protection system and method, and vehicle and medium

A vehicle, comprising a vehicle collision safety protection system,

• wherein the vehicle collision safety protection system comprises:
• a first protection switch unit disposed in a high-voltage circuit of a power battery;
• a second protection switch unit connected in series to a positive electrode of the power battery;
• at least one collision detection unit configured to detect whether the vehicle is involved in a collision;
• and
• a control unit configured to control the second protection switch unit to be disconnected and the first protection switch unit to be disconnected when the vehicle is involved in the collision, to provide dual protection.

A vehicle collision safety protection method, wherein:

• a vehicle comprises a first protection switch unit, a power battery, and a second protection switch unit, wherein the first protection switch unit is disposed in a high-voltage circuit of the power battery, and the second protection switch unit is connected in series to a positive electrode of the power battery;
• and
• the method comprises:
• detecting whether the vehicle is involved in a collision;
• when it is detected that the vehicle is involved in the collision, controlling the second protection switch unit to be disconnected, and controlling the first protection switch unit to be disconnected, to provide dual protection.
