the charging current charging voltage
Second,?the choice of transformer rated power, voltage, electric current
Three, the necessary rectification, current limiting, voltage regulator circuit element must achieve the biggest indicator of the load voltage and current.
Battery charger?charger was among the first to use the transformer type charger.But due to the large volume of transformer charger, bulky, low cost, low charge efficiency, rarely used.Electronic charger is widely used.Around the charger input ac voltage is 220 v, output termination of battery, the charging ways;
First, the large current pulse charging intermittent discharge, compensation;
Second, with constant current, constant voltage floating remain to be rechargeable battery charger?to provide stable voltage and current.Charger with output output short circuit protection, over voltage, over current protection and overshoot protection function, ensure the service life of the battery.
Due to the development of quick charge technology, the concept of traditional lead-acid battery quick charging performance is bad there is a new change.Experimental results show: most valve control type lead acid battery can withstand fast charge, and the reasonable quick charge to extend battery life not only harmless and beneficial.
