Electric vehicles have now become an indispensable travel tool for every household. They must be charged when they are in use. So, should I plug in the power plug first or the battery interface first? I believe it is vague to many people, let’s follow the charger manufacturer to understand it!
1. When charging electric vehicles, the current is relatively large. If the plug of the power source is plugged in first, the battery charger is in the starting state, so that once the battery is inserted, a large surge current will be generated. Excessive impact current is not only easy Damage to the charger will also affect the service life of the battery.
2. The correct method should be to plug in the battery interface first, then plug in the plug on the power end, observe the charging status, the red light is always on, and the whistling of the fan is normal, when unplugging, first unplug the power end plug, then unplug the battery end plug . This can make the charger high voltage disappear quickly, use more reasonable, and it is not easy to damage the charger
Warm reminder: In daily life, some people like to use up the battery before choosing to charge it. Some people like to charge immediately after every ride. In fact, both of these methods are wrong. If the battery is used up and then recharged, it is easy to accelerate the vulcanization of the battery, which will eventually cause the battery to be unusable. Charging every time you ride will reduce the battery life, because the number of charging and discharging of cadmium-free batteries is generally about 350 times. Excessive consumption will also cause the battery to be unusable. The correct method should be to charge the battery immediately when it is less than one-third of its capacity. This will reduce the vulcanization speed of the battery and increase the battery life.
After plugging in the electric vehicle charger, there was abnormal noise and a pile of liquid appeared. In this case, the charger can no longer be used. So what is the reason for the liquid from the charger? Let's follow the charger manufacturer to understand it!
1. There are electrolytic capacitors in the charger, usually liquid. If the capacitor is broken and exploded, the liquid will flow out, it is corrosive and cannot be touched.
2. If the capacitance is broken, it is easy to heat up, so the charger cannot be used without electricity. When the electricity is known to be cold, it may be better. There may be a little electricity, the current is small, and the charging will not enter.
3. The quality of the capacitor channel is very low, and it is easy to be damaged. Replace the electrolytic capacitor when repairing it. However, it is also possible that the charger itself is not very professional, and the self-heating temperature is too high, which damages the capacitors and is not worth repairing. Just change the charger.
