Abstract

The invention discloses an intelligent start-stop lead-acid storage battery formation method. The method mainly includes the following five steps: acid adding and standing, first stage of inner formation, second stage of inner formation, third stage of inner formation, fourth stage of inner formation and the like. By means of acid circulation, the intelligent start-stop lead-acid storage battery formation method provided by the invention can maintain the high temperature formation temperature of an intelligent start-stop lead-acid storage battery precisely at 70-80DEG C in the formation process, and realizes formation of the intelligent start-stop lead-acid storage battery under a high temperature condition. The high temperature condition can accelerate the transformation of active substances at the initial stage of formation and shorten the formation time, also alpha-PbO2 can be generated in the formation process, and the cycle life of the intelligent start-stop lead-acid storage battery can be increased. Moreover, in the process of formation, the heat and gas generated by charging current can be taken away by acid cycle, and the charging current can be increased to realize largecurrent charging in the formation process, thus greatly shortening the formation time.

Description

technical field [0001] The invention relates to the field of lead-acid storage batteries, in particular to an intelligent start-stop lead-acid storage battery formation method. Background technique [0002] Smart start-stop lead-acid battery is a special lead-acid battery, which is developed for cars equipped with smart start-stop system. This system has the characteristics of environmental protection and energy saving, which will be the development trend of automotive energy saving and emission reduction applications in the next 3-5 years. For vehicles equipped with a start-stop system, when the brakes are suspended, the fuel engine stops working, and the battery supplies power to the vehicle; when the accelerator is stepped on to start, the battery drives the engine to start at high speed. The start-stop system effectively solves the exhaust pollution and unnecessary fuel consumption caused by the insufficient combustion of fuel at idle speed. However, due to the frequent...
