Abstract: Based on analysis to the reason of failure and concerning problems of VRLA battery, the key technolo-gies of the BMS (battery management system) were studied. They are：（1）reasonable structure of BMS; (2) battery monitor and data analysis; (3)internal resistance measurement; (4)accident record; (5)capacity and time prediction; (6)remote management. Combined with the experience of BM-6500 battery management system, the related problems were discussed. The system was suitable for VRLA battery used in telecommunica-tion, electric power, railway engine and UPS for back-up and staring.
Key words: VRLA battery; monitor; management; internal resistance measurement
近十几年来，VRLA铅酸蓄电池首先在电信领域得到推广应用，继而在电力、铁路等其它领域逐步取代传统蓄电池。与富液型铅酸电池相比，VRLA具有体积比能量大、放电性能好、维护工作量小等优点。根据现场实际使用情况，由于多方面的原因，VRLA电池在运行过程中出现漏液、变形、短时间内容量衰减以至失效的现象，严重影响了电源系统的运行可靠性。 本新闻共 6页,当前在第 1页 1 2 3 4 5 6 |
