目前,很少有专供大型客车(简称大客车)使用的交流发电机。虽然这并不影响大客车的行驶,但却易造成大客车蓄电池的早期损坏。这是因为,大客车一般行驶在市区,而市区人多车多路口多,使得大客车车速低、启动频繁,这样,蓄电池常处于大量放电状态。同时,由于车速低,发电机转速低,发电量不足, At present, there are few alternators specially designed for large buses (referred to as buses). Although this does not affect the bus’s driving, it can easily lead to the early damage to the bus battery. This is because buses run in the urban area, and many people in the downtown area have many cars and many intersections, making the bus low in speed and frequently in operation. In this way, the battery is often in a state of heavy discharge. At the same time, due to low speed, low speed generator, generating capacity is not enough,
