LOAD DRIVE DEVICE, VEHICLE USING THE SAME, AND LOAD DRIVE DEVICE CONTROL METHOD

摘要

An ECU estimates an output-enabled power (Pmax) which can be outputted by an accumulation device according to the temperature and SOC of an accumulation device (B) (S40). Moreover, the ECU calculates a threshold power (Pth) according to the power required for engine start (S50). When the ECU judges that output-enabled power (Pmax) is lower than the threshold power (Pth) (Yes in S60), the ECU controls a boosting converter (S70) so as to limit the boosting ratio of the boosting converter below a predetermined value.
