A charge and discharge control device is provide. The charge and discharge control device includes a determination circuitry configured to determine an ion diffusion rate associated with electric conduction in a secondary battery, and determine a time integrated value of an overcharged amount of an active material based on the ion diffusion rate and a charge condition; an evaluation circuitry configured to evaluate the charge condition of the secondary battery based on a determination result obtained by the determination circuitry; and a charge and discharge controller configured to control state of current application and voltage application to the secondary battery at a time of charging or discharging the secondary battery based on an evaluation result obtained by the evaluation circuitry.
