Problems solved by technology

[0004] The purpose of the present invention is to overcome the technical problems that the existing battery protection system cannot provide protection for such situations as water ingress in the battery pack, bulging of the single battery, and serious heating of the single battery, and provides a battery protection system with multiple protection functions. When the battery pack is flooded, the single battery is swollen or the single battery is seriously overheated, it can send an alarm to remind the user to check and repair in time to protect the battery pack

Abstract

The invention discloses a battery protection system with multiple protection functions. The battery protection system with the multiple protection functions comprises a battery pack arranged in a battery box, wherein the battery pack comprises a plurality of single batteries, a central processing unit, an alarming module, a water sensor arranged in the battery box, pressure sensors and temperature sensors; each pressure sensor is arranged between adjacent single batteries in the battery box; the temperature sensors are respectively arranged on each single battery; the central processing unit is respectively electrically connected with the battery pack, the alarming module, the water sensor, the pressure sensors and the temperature sensors. The battery protection system can give an alarm to remind a user of overhauling in time and the battery pack is protected when water enters the battery pack and the single batteries swell or severely heat.

Description

technical field [0001] The invention relates to the technical field of electric vehicle battery protection, in particular to a battery protection system with multiple protection functions. Background technique [0002] At present, the battery packs in electric vehicles are equipped with a battery protection system, but the protection system only has basic protection functions such as overcharging, over-discharging, short circuit, and over-current for the battery pack. In addition to overcharge, overdischarge, short circuit, and overcurrent, many other abnormalities often occur, such as water ingress in the battery pack, bulging of the single battery, severe heating of the single battery, and many other safety issues. The protection system currently used Basically, there is no protection related to the above-mentioned battery safety issues. [0003] Chinese Patent Publication No. CN101207276, published on June 25, 2008, the name of the invention is a series lithium battery p...
