Abstract
This invention discloses a method of performance analysis for VRLA battery which applies the method of using the float voltage dispersion ratio of the battery to evaluate the battery performance from a new perspective, and it is an online real-time test which applies several ways to evaluate the performance of the VRLA battery. According to the relevance between the dispersion of the float charge voltage of the battery and its performance, the method gets the result of the battery performance through calculating the battery float charge voltage dispersion ratio and making it relevant with the battery performance. It has small workload, convenient operation and no danger to the system when doing online testing. It also won'"'"'t affect the cycle life of the VRLA battery.
