Battery control unit system
First Claim
1. A battery control system that detects a state of a battery used for driving a vehicle and monitors the state of the battery on the basis of the detected information by use of calculation, so as to control a circuit device surrounding the battery according to a result of the monitoring, the battery control system comprising:
- an internal power source that is connected directly in parallel with the battery, which used for driving a vehicle, without any switch intervention,wherein the internal power source is supplied with power from the battery, andwherein the internal power source supplies power to the battery control system; and
a microcontroller that operates using the internal power source and detects, by a software process, an on/off-state of a battery pack switch that is provided in a battery pack including the battery and the battery control system, all components of the battery pack switch being located along a path distinct from the direct parallel connection between the battery and the internal power source.
