怎么判断电瓶有没有电,请问怎么判断电动车电瓶存不存电?
据和记百科网站「荔莞少年。」消息,近日,怎么判断电瓶有没有电,请问怎么判断电动车电瓶存不存电?引发热议,怎么判断电动车电瓶存不存电同样引起许多争议,对此众网友各抒己见。但到底是怎么回事呢?和记百科为您解答。
1、用万用表检测,检测需要在冷车状态下进行,把万用表测量档调至直流电压20V,红色表笔与电瓶正极接头相连,黑色表笔与负极接头相连,如果电瓶电压低于12V,且高于10V,说明电瓶没电了;如果电瓶电压低于10V,说明电瓶已经报废了。
2、如果车辆出现照明灯光变弱、喇叭声音无力、启动拖泥带水等现象,则说明电瓶电量不足。
1、判断电瓶存不存电方法是用电压表或者比重计测测量蓄电池电量。
2、 在发动机正常温度下,如果12的蓄电池电压高于或等于9.6V时,是无异常情况,电瓶可以存电;低于该电压值则有亏电现象,难以存电。
3、 一般来说,电瓶如果不能存电,是有亏电现象,这种电瓶最好是更换,否则容易影响车辆的使用寿命。
【英文介绍/For English】:
1. Use a multimeter to test, the test needs to be carried out in a cold car state, adjust the multimeter measurement range to DC voltage 20V, the red test lead is connected to the positive terminal of the battery, and the black test lead is connected to the negative terminal. If the battery voltage is lower than 12V and higher than 10V, the battery is dead; if the battery voltage is lower than 10V, the battery has been scrapped.
2. If the vehicle has the phenomenon of weak lighting, weak horn sound, and muddy startup, it means that the battery power is insufficient.
