Analysis of the cause of battery inflation
Battery manufacturer Kanglida Electronic Power Co., Ltd., on the cause of battery drum rise:
a) The vent hole on the battery filling cap is blocked or not clear. During the charging process, especially at the end of charging, a large amount of explosive gas will be generated inside. If the vent hole on the battery filling cap is blocked or not at this time Smooth, these gases can not be discharged in time, so that they accumulate in the battery case, the pressure is getting bigger and bigger, and finally the battery is pumped up.
b) If the battery current is too large or the charging time is too long, when the battery charging current is too large or the charging time is too long, the electrolyte temperature will increase rapidly, and a large amount of gas will be generated, causing the active material on the battery plate to loosen and fall off, resulting in The battery is rising.
c) During the charging process of the high-current charging of the battery in which the vulcanized plate of the battery plate is vulcanized, the single-cell voltage and the electrolyte temperature will rise rapidly, and the bubble generation is early and intense, which easily causes the battery to rise.
d) Continuous start motor time is too long When starting the electric motor, the battery should supply a large current (usually 20~40A) to the motor in a short time, so the large starting current will inevitably cause severe chemical reaction inside the battery. If the battery plate is accompanied by mild vulcanization, it will inevitably lead to a sudden rise in electrolyte temperature and a large amount of gas. Once these gases are not discharged in time, they are prone to explosions. If the starter is used for a long time, it will increase the generation of gas and increase the possibility of battery rise.
e) The inner pole of the battery and the pole and the bus bar are not welded firmly. When the poles and poles of the inner plate of the battery are welded to the busbar, they must be welded firmly and integrated to meet the needs of the battery during high-current discharge. . Otherwise, in the case of large current discharge, the welding site may cause sparking or ablation due to too small contact points or poor contact, thus causing sparks, which will ignite the explosive gas generated by the battery, causing the battery to explode.
f) If the viscosity of the electrolyte is too high, the viscosity of the electrolyte is too high, the rate of penetration into the pores of the plate is slow, the internal resistance is increased, and the voltage drop on the internal resistance during discharge is large, which will cause the electrolyte temperature. It rises rapidly and generates a large amount of gas, which increases the gas pressure inside the battery. If the battery is over-discharged at this time, the temperature of the electrolyte rises faster, the gas is generated more, and the gas pressure inside the battery is larger, and the battery is likely to rise. In addition, if an explosive gas is generated during the charging process of the battery, it will immediately cause an explosion, causing the battery to rise. Therefore, the charging room must be well ventilated and fireworks are strictly prohibited.
