Battery condition monitoring device
First Claim
1. A battery condition monitoring device for monitoring conditions of a battery capable of supplying electric power to a vehicle driving source mounted to a vehicle,the battery condition monitoring device comprising:
- a battery condition detecting section configured to detect conditions of the battery and output detection signals indicating the detected conditions of the battery;
a main control section configured to receive the detection signals transmitted from the battery condition detecting section, and detect whether or not the battery is in an abnormal condition on the basis of the received detection signals, and control an electrical connection state between the battery and the vehicle driving source on the basis of a detection result of the battery; and
a sub-control section configured to detect whether or not the main control section is in an abnormal condition, and control the electrical connection state between the battery and the vehicle driving source, the sub-control section, detecting whether or not the battery is in an abnormal condition on the basis of the detection signals transmitted from the battery condition detecting section when the detection result indicates that the main control section is in an abnormal condition, and control the electrical connection state between the battery and the vehicle driving source on the basis of the detection result of the high voltage battery;
wherein the sub-control section has a self-diagnostic function for the detecting a condition of the sub-control section, andthe sub-control section does not execute a control of the electrical connection state between the battery and the vehicle driving source when the detection result of the self-diagnostic function indicates that the sub-control section is in an abnormal condition even if the ection result indicates that the main control section is in an abnormal condition.

Abstract
A battery condition monitoring device has a control section for monitoring conditions of a high voltage battery on the basis of detection signals detected and transmitted by monitoring ICs. The control section has a main control section and a sub control section. When the main control section is in an abnormal condition, the sub control section detects the conditions of the high voltage battery, and instructs SMRs to turn on and off an electrical connection between the high voltage battery and a vehicle driving electric motor. The SMRs are arranged on connection lines through which the high voltage battery is connected to the vehicle driving electric motor.
