To understand the reason for the boost explosion, we must first understand a noun for the battery, that is, the side reaction. What is a side reaction? If the charging voltage of the battery is too high or the charging time is long, there will be a lot of bubbles, and the important components of a large amount of bubbles are hydroxide mixed gases. Once the hydrogen-mixed gas will explode, once the fire will explode.
In addition, the electrolyte temperature in the battery will also increase, so that the water is largely evaporated, and this is the side reaction that occurs when the battery is charged. 1, the ventilation hole clogging. The vent hole remains unblocked, such as the venting pores on the battery pack cover or not smooth, the gas that occurs in the case of too long or high charging time will gradually accumulate, resulting in a growing pressure in the battery shell, and finally leads to Battery tumble.
2. The charging time is too long. It should not be too long.
When the battery charging current is too large or the charging time will have a lot of gas. In addition, the current is too large or the charging time will also cause the electrolytic liquid temperature to increase rapidly, and this is easy to cause the battery to rise. 3, the battery polar plate has a vulcanization battery polar plate without vulcanization, such as vulcanization of the polar plate of the battery, then in the charging process, the single voltage and the electrolyte temperature will rise rapidly, and the appearance of the bubble is earlier, and the reaction is dramatic.
It is easy to cause battery torch at this time. 4, the continuous start-up motor time is too long, the start-up motor time should not be too long, the battery should supply a large current to the motor in a short period of time, while large boot currents will inevitably cause the internal intenses of the battery. The chemical reaction will accompany the appearance of the gas.
When the launch motor is too long, it will increase the emergence of the gas, which increases the possibility of battery cracking. 5, the bundle of the battery is not firmly welded to the welding point of the battery, and the welding joint is not firmly welded. When the polar panel of the battery is not firm, if the high current discharges, the welding is in contact with the contact.
Detten or in contact with poor contact, caused fire, ablation, this will have sparks, ignite the hydrogen-mixed gas of the battery, resulting in battery explosion. 6, the electrolyte viscosity of the electrolyte is too high or the viscosity is large, such as the electrolyte viscosity is large, and it is easy to cause a slow speed of the penetrating plate pore, which will increase the internal resistance, so that the discharge is consumed in the discharge The voltage drop on the upper voltage increase. This will cause the electrolyte temperature rise rapidly, and there is a large amount of gas, so that the gas pressure inside the battery increases, resulting in the battery drums.
7, the amount of electrolyte liquid too little electrolyte is too small to believe that everyone knows that the battery will cause the electrolyte to reduce the electrolyte or distilled water after the battery is used. After the electrolyte is reduced, the charge over charge will occur, and it will even cause an explosion. 8, the charger damage the charger damage When the charger is damaged or the generator on the engine is damaged, the current or voltage is likely to be large, which is likely to cause a dramatic reaction in the battery, thereby appearing a large number of gases.
Battery tumble. How to prevent battery drums rose above what causes the battery can cause the battery to grow up. So how do we prevent battery boosts in daily work? Let's take a brief talk about it.
1, control the voltage, current. Said above, too large voltage or current is easy to cause the battery to be rising, so control the voltage, current. 2, try to control the charging time, do not let the charging time too long, prevent over charge.
This is also very important. I often see posts related to the boom of the battery in the forum. 3.
Use a better charger or frequently check the generator on the engine. Once the problem is found, it is observed or replaced, preventing the battery to rise. 4, during the charging process, to ensure that each of the terminals is firm, because the wiring point is loose, there will be sparks, which has caused hidden dangers to the battery.
5, ventilation hole guarantee timely smooth. In normal maintenance, clean up the impurities around the battery in a timely manner. 6, check whether the battery housing has cracks, whether the electrolyte leaks.
Because the electrolyte is leakage, it may penetrate into the cable or circuit, thereby causing connectivity, spark. 7. Timely exclude internal short circuit and electrode plate vulcanization in the battery.
Spark in the internal short circuit in the battery, thereby detonating the hydrogen oxygen mixing gas, and the electrode plate vulcanization will cause a large amount of gas inside the battery. Therefore, usually we should check if there is a short circuit inside the battery, whether there is a vulcanization. 8.
It is forbidden to fire on the positive and negative pillars of the battery such as cables such as cables, which is easy to cause explosion of the aerobic hydroxide gas, and severe people will even harm personal safety. 9. When maintaining electric equipment, the flammable gas inside the battery should be excluded.
10. Timely check the amount and density of electrolytic liquid. This will protect the battery to prevent battery drums from.
11. When starting the engine, try to prevent long-term continuous start. .
