A control device comprises: a first identification information acquiring unit configured to acquire first identification information which is identification information for identifying the power accumulation device; a second identification information acquiring unit configured to acquire second identification information which is identification information for identifying the power device; and a determining unit configured to determine, when the first identification information and the second identification information do not match, (i) to prohibit or limit power exchange between the power accumulation device and the power device, (ii) to output an identification abnormality signal indicating that the first identification information and the second identification information do not match, or (iii) not to output an identification normality signal indicating that the first identification information and the second identification information match.

In a battery charging system (100), a charger (110) and a smart battery (160) enhance safety in recharging a cell (180) in the smart battery (160) by a power supply (130) of the charger (110). The smart battery (160) is communicable with the charger (110). If a communication failure occurs, the charger (110) disconnects the power supply (130) from the smart battery (160). The smart battery (160) and the charger (110) share the same symmetric encryption key for encrypting and decrypting message data, allowing one party to determine if the other part is an authentic one. When the smart battery (160) finds that the charger (110) is not authentic, or vice versa, the power supply (130) and the cell (180) are disconnected. When the smart battery (160) finds that a no-charging condition occurs due to abnormality in the cell (180), the smart battery (160) requests the charger (110) to stop charging, and also disconnects the cell (180) from the charger (110) even if the charger (110) fails to stop charging the smart battery (160).
