Research on the Charging Regime of Intelligent Charger of Automotive Valve-regulated Lead-acid Battery

Abstract

Charger has a great impact on the performance and service life of battery and charging regime is significant for intelligent charger. Researchers usually combine two or three charging methods to get a good performance charging regime, but the effect is still less than satisfactory and cannot charge and renovate the battery at the same time. This article studies on charging regime of intelligent charger based on normal charging methods character analysis of VRLA battery and references to some charger products regimes, and gives a seven phases regime including Resonant composite pulse charging, soft start, bulk charge, absorption, battery test, recondition and float. From the result shown in experiments, this charging regime resolves the problem of failing to charge and renovate batteries simultaneously, implementing a high performance charging.
