The utility model relates to electrical equipment acting by receiving power supplied from a battery set having a built-in battery. In the electrical equipment, even if a normal detection signal is not outputted from a temperature sensor inside the battery set, the charging control of the battery still can be conducted properly. A thermistor (28) used for unit temperature detection is arranged in the battery set (20). A thermistor (58) used for substrate temperature detection is arranged on a control circuit substrate (30) of the electrical equipment. If a charging condition of the battery (26) is satisfied, a control circuit (40) sequentially reads a unit temperature (TM1) and a substrate temperature (TM2) which are detected by using the respective thermistors and determines whether the temperatures are respectively within a first temperature range and a second temperature range for allowing the charging of the battery; and if the temperatures are within the temperature ranges respectively, the battery is determined to be allowable for changing and the battery is allowed to be charged, or the battery is forbidden to be charged. |
