Battery car fire prevention tips

Battery cars are favored by more and more people for convenience and environmental protection. However, there is also a small potential for fire hazards in small battery vehicles. Recently, there have been many cases of battery charging to ignite cars to strengthen the maintenance of daily batteries. In order to extend the service life of the battery car.

The reasons for the spontaneous combustion of a battery car mainly include two. One is that the external fire burns to the battery, resulting in melting of lead piles with low ignition points; the other is that the wire connectors on the positive pile head are not fixed tightly, or the conductivity is poor due to corrosion, when large current flows At that time, local high heat was generated due to the large electrical resistance, and lead pile heads were melted.

The culprit that causes the corrosion of the car battery pile head is the sulfuric acid in the battery fluid. Once the engine is started, the generator will charge the battery and hydrogen bubbles will be generated in the battery. Some sulfuric acid components will be discharged along with the hydrogen gas, especially in the When the charging system goes wrong, for example, if the voltage of the generator is too high, or the charging is not controlled, resulting in excessive charging, etc., it will lead to a lot of sulfuric acid components running up to the battery panel, and then the two pile heads will be brutally corroded.

How to remove the sulfuric acid corrosion on the battery pile head? First, open the battery car hood, remove the pile head, and then use alkaline decontamination detergent to spray wash pile head and wire joints, wait until wiped clean, on the top Apply a thin layer of thin butter or Vaseline oil, and then use a wrench to tighten the wire joints on the pile head. To avoid sparking, turn off all interior electrical appliances and ignition before removing the battery pile head, and must first remove the negative Pile head, and then remove the positive pile head. And when you replace the pile head, then install the positive pole and then install the negative pole. In addition, if you are not sure, it is best to consult in advance the original operating process which safety precautions.
