Do not replace the original charging head casually: most of the main parameters of lithium battery chargers in different vehicle lines are different. Do not replace the charging head casually without mastering it. If you need to install a new charging head, please go to the pure electric vehicle store to buy a special charging head.

Do not use the charging head with cooling fan: many customers think that the charging head with cooling fan is very simple to discharge heat and charge the battery well. In fact, this kind of understanding is also incorrect. On the one hand, the lithium battery charger with cooling fan is very simple and bad; On the other hand, the heat dissipation electric fan is very simple to accumulate dust in the whole process of use, which is likely to cause uneven internal heat discharge and damage the charging head.

Do not buy low-cost fake and shoddy charging heads: when the lithium battery is saturated, the heat discharge of the centrifugal fan of the fake and shoddy charging head will be terminated during operation. When the rechargeable battery is overcharged, if the heat exhaust fan stops working again, the temperature of the charging head may double, which will not only burn the charging head seriously, but also continue to cause short-circuit fault and fire.
