Several factors can contribute to a battery becoming excessively hot while charging. Some common causes include using a charger with the wrong specifications, overcharging the battery, charging at a high current rate, or exposing the battery to extreme temperatures during the charging process.
Batteries can be discharged over a large temperature range, but the charge temperature is limited. For best results, charge between 10°C and 30°C (50°F and 86°F). Lower the charge current when cold. Nickel Based: Fast charging of most batteries is limited to 5°C to 45°C (41°F to 113°F).
If you notice the temperature exceeding the recommended range, stop charging and allow the battery to cool down before continuing. – Choose the Right Charging Method: Select the appropriate charging method based on the battery type and manufacturer recommendations.
This results in self-heating and a possible explosion. While subjecting batteries to extremely high temperature (>50°C) is risky, low temperature is equally harmful. At very low temperatures, that battery degrades faster than it should. Hence, it is crucial to maintain the homogeneity of the temperature distribution within a battery pack.
Batteries do not perform well when it is too hot or too cold. Poor thermal management will affect the charging and discharging power, service life, cell balancing, capacity, and fast charging capability of the battery pack. For instance, with just a 10-degree rise in the temperature, the battery life will reduce by 50%.
