Claim:
1. A storage status adjusting circuit including two or more modules to control energy accumulation in, and energy release from, plural respective coils to plural assembled electric storage devices respectively, each assembled electric storage device including plural component electric storage devices connected serially to each other, each of the two or more modules comprising: plural switching units to selectively connect respective component electric storage devices of a corresponding assembled electric storage device to a corresponding coil; a voltage detection circuit to detect voltages of the component electric storage devices of the corresponding assembled electric storage device; a controller to set a reference voltage based on comparison amongst the detected voltages of the component electric storage devices of the corresponding assembled electric storage device; and a coil voltage adjusting circuit to control an amount of energy accumulated in the corresponding coil based on the reference voltage set by the controller, wherein each of the modules further comprises a first switching unit to switch between energy accumulation and energy release of the corresponding coil, wherein the plural switching units connect or disconnect the respective component electric storage devices with the coil, wherein the plural switching units disconnect the respective component electric storage devices from the corresponding coil when the first switching unit is switched to energy accumulation of the corresponding coil, and wherein any one of the plural switching units connects the corresponding component electric storage device with the corresponding coil when the first switching unit is switched to energy release of the corresponding coil.
