The invention discloses a railway vehicle lithium battery safety protection system. Compared with the prior art, redundancy setting is carried out on the whole monitoring line, and the reliability and safety of fault alarm are improved. And on the other hand, the second battery state monitoring unit performs fault judgment and identification through a pure hardware circuit, so that the reliability of fault alarm is further improved. When the lithium battery works, the first fire detector and the second fire detector work at the same time and are mutually redundant. When the lithium battery does not work, the second fire detector can still extinguish fire through the temperature sensing magnetic power generation device when the battery is overheated. According to the invention, adhesion fault detection can be carried out, main contact fault detection can also be carried out, and fault early warning can be carried out when a fault is detected, so that maintenance and replacement can be carried out in time, and the safety of a lithium battery system is improved.
本发明公开了一种轨道车辆锂电池安全保护系统。与现有技术相比,本发明对整个监控线路都进行了冗余设置,提高了故障报警的可靠性和安全性。另一方面,第二电池状态监控单元通过纯硬件电路进行故障判断和识别,进一步提高了故障报警的可靠性。当锂电池工作时,第一火灾探测器和第二火灾探测器同时工作,相互冗余。当锂电池不工作时,第二火灾探测器仍可在电池过热时通过温感磁发电装置进行灭火。不仅能进行粘黏故障检测,还能进行主触头故障检测,并在检测到故障时进行故障预警,以便于及时进行维护和更换,提升锂电池系统安全。
