PROBLEM TO BE SOLVED: To facilitate regenerative control employing CVCC control while reducing cost and enhancing stability and reliability. SOLUTION: A CV controller 50 generates a current command value (Icv) for controlling the voltage of a discharge path 60 to a target level based on a voltage command value (Eref=upper limit charging voltage value OV) designated by a host controller 30. A comparison processing section 52 compares the current command value (Icv) designated by the CV controller 50, a current command value (Iref) designated by the host controller 30, and a preset upper limit current value (Iccmax) and a lower limit current value (Iccmin) and then determines a current command value (Icc) fed to a CC controller 54 based on the comparison result. The CC controller 54 controls the current amount of the discharge path 60 based on the current command value (Icc) determined at the comparison processing section 52. COPYRIGHT: (C)2005,JPO&NCIPI |
