摘要： To accurately estimate an internal temperature of a chargeable battery by simple calculation. A chargeable battery temperature estimation apparatus that estimates internal temperature of a chargeable battery includes: a current acquiring means for acquiring a detected current value output from a current sensor configured to detect a current flowing in the chargeable battery; a calculating means for calculating a heating value on the basis of the detected current value, with the heat being generated, according to a current, inside the chargeable battery; a temperature acquiring means for acquiring a detected temperature value output from a temperature sensor configured to detect an external temperature of the chargeable battery; an estimation means for estimating an internal temperature of the chargeable battery according to a current and an external temperature, based on the heating value and the detected temperature value; and an output means for
