1 The rise, it will evaporate the water, when the vent hole cover is blocked, because the gas is too late to overflow, the pressure inside the battery will rise high, first causing the soldier battery cell to deform, when the internal pressure reaches a certain pressure It will burst from the battery slot cover or other weakness, this is a physical process. When the internal pressure of the battery is higher than 0.25 MPa, the battery is burst, and the burst position is located at the edge of the tank hot air bond or the edge angle of stress aggregation.

2. Hydrogen is meticulous, and the explosive limit of the battery explosion H2 and O2 mixed gas formed by H2 is H2 4% -96%, H2 and air mixed gas of H2 and air is a 4% -74 of the mixed gas volume. %.

If 80% of the charge amount is used in electrolytic water, the H2 content inside the battery is larger than the explosion range. When the amount of hydrogen in the battery or the amount of hydrogen is accumulated to the explosion limit, it will form an open fire to form an explosion, this is one Chemical reaction. Studies have found that the explosion of the battery belongs to the branched explosion reaction.

There are too many such explosions that occur in the case of overcharge. A qualified battery does not have a self-heating explosion in normal use conditions. When the battery charging voltage gasoline car is higher than 14.

4V, the diesel car is higher than 28.8V, and the explosion may occur under the conditions of the simultaneous existence. Through the vehicle inspection of the battery explosion, it is found that most of the voltage regulators have defects, and the battery is in a serious overcharge.

3. Due to the blocking of the battery exhaust hole, the soldier battery burst, burst causing the battery vibration, the pole column wiring does not have a spark, thereby forming an explosion. .
