ELECTRIC VEHICLE
First Claim
1. An electric vehicle comprising:
- a first power storage unit;
a second power storage unit having a voltage higher than that of the first power storage unit;
an output detector that detects an output of the first power storage unit;
a collision detector that detects a vehicle collision;
an information recorder to which the first power storage unit is connected as a power supply and which records collision information from the collision detector;
a circuit opening/closing unit that is provided between the second power storage unit and the information recorder and is switched between a first state in which the second power storage unit and the information recorder are separated from each other and a second state in which the second power storage unit and the information recorder are connected to each other; and
a controller that switches the circuit opening/closing unit from the first state to the second state in a case where the vehicle collision is detected by the collision detector and a reduction in the output of the first power storage unit is detected by the output detector, whereinthe information recorder records the collision information from the collision detector by using the second power storage unit as a power supply in the case when a vehicle collision is detected by the collision detector and the reduction in the output of the first power storage unit is detected by the output detector.

Abstract
An electric vehicle includes: a low-voltage battery, a high-voltage battery having a voltage higher than that of the low-voltage battery; an output detector that detects an output of the low-voltage battery; a collision detector that detects a vehicle collision, an information recorder to which the low-voltage battery is connected as a power supply and which records collision information from the collision detector; a power supply relay unit that is provided between the high-voltage battery and the information recorder and switched between an opened state in which the high-voltage battery and the information recorder are separated and a closed state in which that are connected; and a controller that switches the power supply relay unit from the opened state to the closed state in the case when a vehicle collision a reduction in the output of the low-voltage battery are detected.
