PROBLEM TO BE SOLVED: To prevent deterioration of secondary battery when the cooling performance of cooling means deteriorates, in a charge and discharge control system of secondary battery.SOLUTION: A charge and discharge controller 50 in a charge and discharge control system of secondary battery changes the allowable charge and discharge power of a secondary battery 20, according to the cooling performance of a cooler 30 cooling the secondary battery. The charge and discharge controller 50 includes a cooling performance calculation unit 52 for calculating the cooling performance of the cooler 30, a cooling performance determination unit 54 for determining whether or not the cooling performance is equal to or below a specified performance, and a cell temperature determination unit 56 for determining whether or not the cell temperature is equal to or above a prescribed temperature. The controller 50 further includes an allowable charge and discharge power change unit 58 for changing the allowable charge and discharge power.SELECTED DRAWING: Figure 1
