Abstract
A device and method of input/output control capable of exhibiting the battery performance by nature by rapidly raising the temperature of the secondary battery by the regeneration at a low temperature. A temperature rise controller controls the temperature rise of the battery pack based on the battery temperature, thereby determining a central value of the state-of-charge control in the range of the state of charge. A battery input/output controller voluntarily controls the state of charge based on the central value of the state-of-charge control from the temperature rise controller and the state of charge at the point of time from the state-of-charge operator, and controls charge and discharge based on the charge and discharge request from the outside to the battery pack.
