What caused the explosion of the UPS battery?

Reasons for UPS battery explosion ● UPS battery is charged to the end, after the two poles are converted into effective substances, and then continue to charge, a large amount of hydrogen and oxygen gas will appear, and excessive internal pressure will cause an explosion. In the case of overcharging, if there are virtual solder joints at the internal poles, through-wall welding, etc. of the UPS battery, the battery has a higher probability of explosion. If the battery vent is blocked, the battery will burst first, and the burst will cause the battery to vibrate. If the pole wiring is not secure, sparks will also cause an explosion. ●Excessive internal pressure of the battery may cause the battery shell to explode. The pressure inside the UPS battery will rise very high, causing the battery tank to deform first. When the internal pressure reaches a certain pressure, it will burst from the joint of the battery tank cover or other weak points. This is a physical process. When the internal pressure of the battery is higher than 0.25MPa, the battery will burst, and the burst location is located at the hot air junction of the tank cover or the corner where the stress is concentrated. ●The explosion limit of the battery formed by hydrogen encountering open flame is that the explosion limit of H2 and O2 mixed gas is 4%-96% of the volume of the mixed gas, and the explosion limit of the mixed gas of H2 and air is 4%-74 of the mixed gas volume of H2 %. If 80% of the overcharge is used to electrolyze water, the H2 content inside the battery is greater than the explosion range. When the hydrogen content in the UPS battery or in the air accumulates to the explosion limit, it will explode when exposed to an open flame. ●Because the vent of the battery is blocked, the battery burst first, and the burst will cause the battery to vibrate, and sparks will appear when the pole wiring is not strong, thus causing an explosion.
