Battery monitoring and protecting device and system and method thereof

Abstract

Provided are a battery monitoring and protecting device and system and method thereof. The battery monitoring and protecting device is used in coordination with a battery module and comprises a sensing module and a control module in electric connection with the battery module and the sensing module. The sensing module comprises an acceleration sensing unit for sensing changes of inclination angle and acceleration of the battery module, a temperature and humidity sensing unit for sensing changes of the temperature and humidity of the battery module, and at least one gas sensing unit for sensing changes of gas of the battery module. The control module controls the battery module to be charged or discharged according to the sensing result of at least one sensing unit to sense the temperature, humidity, voltage and currents of the battery module, achieve battery capacity calculation and short circuit detection and sense whether the battery module is in states of intense impact, tilting, turnover, dropping-down, immersion and the like, and immediately cuts off power output of the battery module when abnormal conditions occur.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a battery monitoring and protection device. Background technique [0002] With the rapid development of the technology industry, various fields have been integrated with the application of electronic technology to further enhance the value and advantages of competition. [0003] In terms of automotive electronics technology, automotive batteries are the power source that mainly supports related auxiliary equipment such as light-emitting diodes (LEDs), multimedia audio and video, and global positioning systems (GPS). However, the battery management system in today's vehicles can only sense The charging and discharging status of the battery (for example: overcharge or overdischarge) cannot be properly monitored and monitored when the vehicle is hit hard, overturned, dropped, burned, etc., or the electrolytic tank of the battery leaks, etc. Protection, so that when these special conditions oc...

[0003] In terms of automotive electronics technology, automotive batteries are the power source that mainly supports related auxiliary equipment such as light-emitting diodes (LEDs), multimedia audio and video, and global positioning systems (GPS). However, the battery management system in today's vehicles can only sense The charging and discharging status of the battery (for example: overcharge or overdischarge) cannot be properly monitored and monitored when the vehicle is hit hard, overturned, dropped, burned, etc., or the electrolytic tank of the battery leaks, etc. Protection, so that when these special conditions occur, the battery will continue to supply power to the main system circuit in the vehicle, resulting in the risk of short circuit, fire or even explosion
