摘　　要：后备电池的浮充工况不同于循环充放电工况,后备用磷酸铁锂电池沿用了与循环充放电工况相同的电池管理方法,造成电池组管理不当,引起电池寿命衰减严重、电源供电故障、甚至是安全事故,论述了磷酸铁锂电池浮充工况特性及管理方法,对提升后备磷酸铁锂使用性能具有重要意义。The floating charge condition of the backup is different from the cycle charge-discharge condition,but the backup lithium iron phosphate battery used the same battery management method of the cycle charge-discharge condition.It resulted in a lot of management problems,such as serious battery life degradation,power supply failure,and even safety accidents.The resreach analyses the characteristics and management methods of floating charge condition of lithium iron phosphate battery,and promotes the development and performance of the backup battery.
