通过对失效铅蓄电池的拆解及蓄电池与整车匹配性分析,找到了这批换件铅蓄电池早期失效的综合原因。鉴于多种因数都会导致蓄电池早期失效,建议在新车开发的过程中充分考虑电池和整车耗电系统的匹配,并在电池生产、储存环节控制其硫酸盐化现象发生。 相似文献

It is estimated that about 80% of all photovoltaic (PV) modules are used in stand-alone applications. Continuous power is obtained from PV systems by using a storage buffer, typically in the form of a lead acid battery. Batteries used in PV applications have different performance characteristics compared with batteries used in more traditional applications. In PV applications, lead acid batteries do not reach the cycle of lead acid batteries used in other applications such as uninterruptible power supplies or electric vehicles. The shortened battery life contributes significantly to the costs of a PV system. In some PV systems the battery accounts for more than 40% of the life cycle costs. An increase in the lifetime of the battery will result in improved reliability of the system and a significant reduction in operating costs. The life of a lead acid battery can be extended by avoiding critical operating conditions such as overcharge and deep discharge. This paper presents a battery management system for such applications 相似文献
