马股庄321860V充电器输出75Ⅴ正常的吗
项刚才19838783064 ______ 正常,电动车充电器60伏输出电压75伏,输出的电压基本上属于正常电压,因为只有电压高的才可以输出到电压低的电瓶里.但是在充电过程中始终不转灯,我认为是充电器里面的保护板接触不良或者被烧坏造成的原因,希望找一个专业人士去维修一下自己因不懂所以不会修理. 60V充电器输出75Ⅴ正常的吗 60v充电器的额定电压为60v,当60v的充电器给与其匹配的电池充电时的实际输出电压要大于其额定电压,在65一70v之间,所以60v充电器的实际输出电压在65一70v之间为正常值,如果60v的充电器输出75v的电压则是不正常的,可能是充电器的限压继电器损坏了.
