摘要
蓄电池是汽车的重要电源,起动发动机时,给起动系统、点火系统、电子燃油喷射系统及其他电气设备供电。汽车上的蓄电池,必须满足起动发动机的需要,即在5~10s的短时间内,提供汽车起动机足够大的电流。汽车蓄电池一旦自放电过大,就会影响到汽车的启动,因此,必须查出放电的原因,彻底排除故障。
As vital power supply of automobiles, battery provides power to starting system, ignition system, electric fuel injection system and other electrical equipments of automobiles. To meet the requirements of starting the engine, the battery have to provide sufficient electric current in 5 to 10 seconds. Meanwhile, excessive self discharge of the battery will also impact the starting of automobiles. So the causes of battery self-discharge must be found out.
