Abstract

The invention relates to an energy storage lead-acid battery charging technology. The charging technology is divided into five phases, namely an activating phase, a deep discharging phase, a reactivating phase, a capacity detection phase, and an electricity supplementing phase. A battery is manufactured through the charging technology mentioned above, the circulation service life of the battery is prominently prolonged, the capacity is large in the primary period, the battery can be charged for 1600 times or more in a cyclic charging mode of insufficient charging and sufficient charging, and overcharging and insufficient discharging, and no white spot or mud appears on the electrode plate surface. The technology is an ideal charging mode for energy storage battery.

Description

technical field [0001] The invention relates to the field of accumulators, in particular to a charging process for lead-acid accumulators suitable for energy storage, which is suitable for charging and discharging cycles at various ambient temperatures and has a high cycle life of the batteries. [0002] Background technique [0003] Lead-acid battery (Lead-acid battery) electrodes are mainly made of lead and its oxides, and the electrolyte is a battery of sulfuric acid solution. Since the French G.Plante invented the lead-acid battery in 1859, it has experienced nearly 150 years of development. Great progress has been made, whether it is in transportation, communication, electric power, military or in various economic fields of navigation and aviation, lead-acid batteries have played an indispensable and important role. In recent years, with the acceleration of urbanization and the expansion of city limits, the traffic flow has increased dramatically. Although automo...
