It is recommended to stop charging immediately and replace the battery with a new one. Lithium battery aging, internal resistance increases, electrolyte drying, internal short circuit and other battery problems caused by heat.
With the increase of the number of times the battery is used, including discharge and charging, the water molecules in the battery are gradually lost, resulting in the battery heating in the electrochemical reaction; In addition, the battery solution forms sulfuric acid crystals during the charging and discharging process, which precipitates and sticks on the plate, resulting in increased battery resistance and heating; If the battery is due to short circuit caused by the battery heat, the best way is to replace the new battery.
It is recommended to stop charging immediately, and then start charging again with a smaller current after cooling.
48V lithium battery charging, the battery will certainly have a certain temperature rise, but as long as the reasonable charging current, this temperature rise will not lead to high temperature.
When the battery temperature is too high during charging, power off in time, check whether the charger current is too large, and whether the battery is damaged, and confirm that there is no anomaly before charging again.
