A voltage conversion control apparatus is a voltage conversion control apparatus which controls a voltage converter having an upper switching element and a lower switching element, and has a calculating device which calculates duty ratio such that output current of an electricity storage apparatus reaches target value and the duty ratio is within predetermined allowable range; a limit relaxing device which relaxes at least one of upper limit value and lower limit value of the allowable range on the basis of magnitude relationship between predetermined threshold value and current deviation which is obtained by subtracting the output current from the target value; and a controlling device which controls the upper switching element and the lower switching element to perform a switching control on the basis of the duty ratio which is calculated by the calculating device.
