Abstract
The present invention relates to a system and a method of protecting a battery, and particularly to a system and a method of protecting a battery, which compare current state information of a battery with reference state information and control an operation of a power supplying unit that supplies power supplied from the battery to a load based on a result of the comparison in order to block power supplied from the battery that is in a problem state, thereby protecting a load from the battery in the problem state.
Claims18
A system for protecting a battery, the system comprising a battery management system coupled to the battery, to a load, and to a main control unit, the battery management system further comprising a second control unit, wherein the battery management system is further configured to:
- generate reference state information of the battery;
- compare current state information of the battery with the generated reference state information;
- output a comparison result signal to each of the main control unit and the second control unit based on the comparison of current state information of the battery with the generated reference state information;
- at the second control unit, set the battery management system to a stop state;
- and
- block a power output from the battery to the load based on the comparison result signal until a signal releasing the stop state is received from the main control unit.
A method of protecting a battery, the method performed by a battery management system coupled to the battery, to a load, and to a main control unit, the battery management system further comprising a second control unit, the method comprising:
- generating reference state information of a battery;
- comparing current state information of the battery with the generated reference state information and outputting a comparison result signal;
- outputting a comparison result signal to each of the main control unit and the second control unit based on the comparison of current state information of the battery with the generated reference state information;
- the second control unit setting the battery management system to a stop state;
- and
- blocking power output from the battery to the load based on the comparison result signal until a signal releasing the stop state is received from the main control unit.
