The chemical principle of drum bag first we must understand that any model of battery is not a lead-acid battery. There will be some hydrogen during charging, so the battery manufacturer will reserve the stamp during the generation process so that hydrogen is in the process of charging in the future. discharge.
If the gap is too small or if there is no gap, there is no gap, then the hydrogen will get more, and finally the battery shell. The reason for the drum bag in electric vehicle battery 1. First of all is that the production and manufacturing process is unqualified.
If the electric car market is mixed, many companies are not uniform due to the limited manufacturing level of the battery, and the electrode coating is uneven, and there is no stitches to the battery. Such a battery is extremely easy to happen. 2.
Battery overshoot. The battery overshoot is easy to cause fire, and on the other hand, it will also cause battery drums. The battery overshoot will cause a lot of heat, causing electrolyte to decompose gasification, and the battery is drumping.
Electric vehicle charging 3. The charging current is too big to change the battery and electric cars, and the other owner is cheap to buy cheap mismatched charger, and the different sized batteries have a specified voltage current. If the charging current is too large In order to cause excessive precipitation on the electrode plate, thereby causing the chemical reaction, the temperature is too high, the exhaust gas is not in time, there will be a battery drum.
4, the safety valve pressure is high, the electric car battery has a safety valve in order to ensure safety, when the pressure in the electric vehicle battery rises, the safety valve will automatically open, perform pressure to ensure battery Internal and external air pressure balance. When the pressure is rising in the battery, the safety valve cannot be opened normally. For a long time, since the pressure in the battery is too high, the internal and external gas pressure is unbalanced, there will be a phenomenon of drums.
Drums are one of the many phenomena. Of course, it is also a common battery problem. In addition, the battery of electric vehicle will have lost water, imbalance, sulfate, and polar plate softening, etc.
How to prevent battery drums, extend the life? Aspect is guaranteed. 2. Regularly check the battery's consumable product, the longer the cycling time, the more mileage, the life will gradually decrease, if you pay attention to maintenance, regular maintenance, find problems in timely, then the battery life will have new.
Electric vehicle battery 3. Please handle the battery in time, please repair or replace the new battery in time, on the one hand, the drum bag, the performance of the battery decreases, as the owner, you will also find the electric car without heart, and during the charging process, Extremely dangerous, so regularly check the battery, observe whether the battery is working properly. Some users, after returning to their own riding, they like to immediately charge the electric car.
And this charging method will accelerate battery loss, and even cause drum bags. Why does this happen? Because suddenly stopped after driving for a while, the battery will still maintain a high temperature, and at this time, the temperature will make the temperature higher. So wait for half an hour, then the battery is cooled and then charging, so it can prevent electric vehicle battery drums, extend battery life.
