An internal condition detection system (5) detects a charging and discharging current and a terminal voltage of a charge accumulating device (1 ), and learns the internal condition quantity of the charge accumulating device (1) through a neural network (52) based on the current values and the terminal voltage values. The current values and the terminal voltage values are stored in a buffer (51) and supplied as time-series data so that historical information is included. Further the neural network (52) is fed with type information of the charge accumulating device (1). The type information is stored in a memory (53). <IMAGE>
