Power storage system and control device of power storage device

A power storage system mounted on a vehicle, the power storage system comprising:

• a power storage device configured to perform charging and discharging;
• a voltage monitoring unit configured to detect a voltage of the power storage device and output first identification information;
• a memory unit configured to store in advance second identification information, the second identification information being identification information about the voltage monitoring unit corresponding to control information predefined for the power storage device;
• a motor generator configured to receive power from the power storage device to generate kinetic energy used for a travel of the vehicle;
• an inverter configured to convert a direct power of the power storage device to an alternating power and output the converted alternating current power;
• a voltage sensor configured to detect a voltage of the inverter, and
• a controller configured to
• (a) control charging and discharging of the power storage device,
• (b) perform consistency determination processing, the consistency determination processing determines whether the first identification information and the second identification information are consistent,
• (c) perform the consistency determination processing again, when the controller determines that the first identification information and the second identification information are consistent and when the power storage device is started by a user, and
• (d) control charging and discharging of the power storage device using the voltage of the inverter, the voltage of the inverter being detected by the voltage sensor, when the consistency determination processing is performed again and when the controller determines that the first identification information and the second identification information are not consistent.
