随着汽车电子技术的不断发展,汽车电器元件日益增多,经常有驾驶人抱怨车辆放置一段时间就会出现蓄电池亏电,无法起动的故障。笔者结合维修实践,总结出导致斯柯达轿车蓄电池亏电的原因一般有3点:蓄电池充电不良;蓄电池自身故障;静态放电过多。其中第3种情况较为常见,下面逐一进行分析。1蓄电池充电不良故障原因发电机到蓄电池之间的线路存在虚接;发电机发电量不足。排除方法起动发动机,关闭所有电器,测量发电机正极与其外壳之间的电压(发电机的输出电压),应在13.5 V以上,
With the continuous development of automotive electronics technology, increasing the number of automotive electrical components, drivers often complain about the vehicle placed for a period of time there will be battery power loss, can not start the fault. The author combines the practice of maintenance, concluded that the cause of the Skoda car battery power loss generally has 3 points: poor battery charging; battery itself fault; static discharge too much. The third case is more common, the following one by one for analysis. 1 bad battery charging problem generator-to-battery line exists between virtual connection; generator generating capacity is not enough. Exclusion method Start the engine, turn off all appliances, measuring the voltage between the generator positive and its housing (generator output voltage) should be above 13.5 V,
