Abstract

An apparatus includes a battery having a battery monitoring unit (BMU) and an outer casing, and a resistance measuring device coupled to the outer casing. The battery monitoring unit and the resistance measuring device monitoring a change in surface temperature on the casing of the battery during a charging or discharging of the battery, compare the change in surface temperature with an expected change in surface temperature during the charging or discharging of the battery, and determine that a swelling of the battery has occurred when the change in surface temperature is less than the expected change in the surface temperature.
