Zhengzhou conley of electronic power co., LTD., founded in 2000, professional development, production, sales of 2 v, 4 v, 6 v, 12 v four series and maintenance-free lead-acid battery, gel battery and electronic charger, etc. Products are widely used in security alarm system, fire alarm system, building intercom system, elevator emergency evacuation system, emergency lights, antenna, power sprayers, electronic said, children, cartoon gas mould, washing machine, rotary table, parking lock, flashing lights, traffic lights, dc panel, solar energy, wind energy, UPS, EPS, etc for electrical system.

　　The time it takes for an engine to charge a battery has little to do with time. Normal engine idle speed, charging indicator light goes out, then began to power generator, the higher the engine speed, the greater the capacity to, after the generator capacity meet the on-board electrical power, would show the rest of the accumulator.

　　Car motor, ac motor, storage battery and electrical load is an interconnected system, which means the engine idle speed, according to the power of the car, the electric currents generated by generator can give the accumulator is not many, but can promise not to let battery power.

　　The energy balance on the car also need to consider, after engine shutdown restart must want to consider the state of charge of battery, the battery can be thought of as an accumulator, for a variety of load power supply, in turn, alternator must give battery charging, as its energy provider. If the battery charge exceeds the charge, then how much capacity of the battery will be discharged step by step until it is empty. So a lot of people say that the ideal state is to have a balance between the input and the output of the battery.

　　In fact, the charging indicator light on the vehicle does not tell whether the battery is charging or not, nor does it tell what speed the engine is charging. When the ac generator is under heavy load, the charging indicator lights will go out. The battery is not charging but discharging. It is also important to note that if the charging indicator light does not go off at high speed, then the ac generator, voltage regulator, circuit or transmission belt will fail.
