Abstract: A vehicle in one exemplary embodiment of the present invention includes a power control unit, a first control unit, and a second control unit. The first control unit further acquires collision prediction information indicating whether there is a possibility that the vehicle will collide and executes the discharge control if (i) the collision information is received, (ii) an abnormality occurs in the communication with the second control unit and, the collision prediction information indicates that there is a possibility that the vehicle will collide, or (iii) a voltage of an auxiliary power supply becomes lower than a threshold voltage and, the collision prediction information indicates that there is a possibility that the vehicle will collide.

Abstract: A battery system for a vehicle includes an auxiliary battery, first electric loads electrically connected to the auxiliary battery through first relays, a first electronic control unit electrically connected to the auxiliary battery through a second relay, the first electronic control unit being configured to turn on and off at least the first relays and the second relay, and a collision detection device configured to transmit a collision detection signal to the first electronic control unit when detecting a collision of the vehicle. The first electronic control unit is configured to switch the first relays from on to off, while keeping the second relay turned on when receiving the collision detection signal.
