Do you know what are the important reasons for the explosion of lead-acid batteries?

The internal pressure of the battery is too high: It is known that in the battery charging process, especially at the end of charging, due to overcharging, water is decomposed into hydrogen and oxygen, short circuit, severe sulfidation, and sharp rise in electrolyte temperature during charging will cause a large amount of water to evaporate. If the vent hole of the filling hole cover is blocked, the pressure inside the battery will rise very high due to too much gas to overflow, which will cause the battery tank to deform first. When the internal pressure reaches a certain pressure, it will be from the joint of the battery tank cover or other weak points. burst. ●Explosion due to clogged vent: As the vent of the battery is blocked, the battery will burst first, and the burst will cause the battery to vibrate, and sparks will occur when the pole wiring is not strong, thereby causing an explosion. ●Hydrogen encounters an open flame to cause battery explosion: The explosion limit of H2 and O2 mixed gas is 4%~96% of the volume of the mixed gas, and the explosion limit of H2 and air mixed gas is 4%~74% of the volume of the mixed gas. When the hydrogen content generated by the battery accumulates to the explosive limit, it will explode when it encounters an open flame, which is a chemical reaction. From the explosion mechanism of the above lead-acid batteries, it can be seen that in the use process, it is necessary to prevent the explosion of the battery from two aspects: preventing the formation of explosive gas mixtures and putting an end to open flames. The specific measures are as follows: a) The battery charging room is well ventilated and there is no open flame; b) Use matching charging equipment, but charge; c) The cable connection should be firm and reliable to prevent sparks due to looseness; d) The air vents of the battery are kept unobstructed; e ) Whether the output voltage of the regulator is within the specified range, the general gasoline vehicle does not exceed 14.4V, and the diesel vehicle does not exceed 28.8V.
