Why does the battery drum? What is the cause of the drum bag

Cause 1. The previous lead-acid battery is generally used in the traditional cadmium formulation and the application of the process technology. The cadmium-containing lead-acid battery has anti-high temperature and large current, but the environmental pollution is relatively large; and the current lead-acid battery Cadmium is strictly prohibited, charged during high temperature and large current situation, the battery drum bag is inevitable.

Cause 2, summer, charger charges 48V battery, general voltage is 55V, while the voltage charged in winter is generally 61V, temperature can be controlled between -22 ¡ã C and 55 ¡ã C. If the charging voltage set by the charger exceeds this value, it means that the battery will be overchaled; overcharge will cause the battery to lose water until the heat is out of control. Generally, the battery is overcharged, and the phenomenon of summer drums is much more serious than in winter! Cause 3.

Cause 4 Drum. Cause 5, often using the fast charging station charging causes the battery to be dried to account for about 5%. The fast charging station is charged with a large current period, which will cause the battery to be severely lost, and long-term use is an important reason for the battery drum.

Cause 6, if the charger mixed with different models can also cause the battery to be drumped. Different models of batteries, the charger is different, but some electric car users are in the process of use, they often mix, take 60V charger, charge 48V, take 20ah charger charge 12AH battery , Charging voltage and current do not match, it will cause the battery to be drumped. Cause 7,‍‍‍In general, electric car batteries will have a safe valve, which will release too much pressure through this valve, but some batteries are not normal because the safety valve is not good, so that the drum bag is deformable.

Cause 8 Cause 9: Although the charger is good, but long-term bumps in the car, the components may cause demondering, resulting in poor contact, causing the current instability and protection function when charging, causing the battery to be drummed. Cause 10, summer high-temperature exposure battery or charging ambient temperature is too high, and it will also cause deformation of the battery shell. Depending on the battery power, the charger can be floated after 2 hours.

After the ambient temperature is high, the surface temperature of the battery should be naturally cooled, and charging is charged to prevent charging in a high temperature environmen.
