Battery management system and method thereof
First Claim
1. A battery management system, comprising:
- a switch module;
a power supply module, electrically coupled to a load or a charging power source via the switch module;
a measurement module, configured to measure a plurality of operation signals from the power supply module; and
a processing module, configured to determine an operation status of the power supply module by cross comparison between the operation signals, and activate a safety protection item according to the operations signals and the operation status, wherein the processing module determines to activate a global protection process to turn off the switch module or activate a local protection process to turn off the switch module after a buffer time.

Abstract
A battery management system is provided, which may include a power supply module, a measurement module, a switch module and a processing module. The power supply module may be electrically coupled to a load or a charging power source via the switch module. The measurement module may measure a plurality of operation signals from the power supply module. The processing module may determine the operation status of the power supply module by cross comparison between the operation signals, and activate a safety protection item according to the operations signals and the operation status; the processing module may determine to activate a global protection process to turn off the switch module or activate a local protection process to turn off the switch module after a buffer time according to the danger level of the safety protection item.
