Abstract
In a power supply system, a plurality of voltage converters have chargeable/dischargeable batteries connected to the respective primary sides and have respective secondary sides connected in parallel to each other. For each of the voltage converters, a voltage transformation rate is set such that the current measured by a primary side current measuring instrument is maintained within a first range between the discharge current maximum value of the batteries connected to the primary sides and the charge current maximum value of the batteries.
Claims8
A power supply system comprising:
- a plurality of batteries that are rechargeable and dischargeable;
- a plurality of voltage converters each having a primary side connected to one of the plurality of batteries, the plurality of voltage converters having respective secondary sides connected in parallel to each other, each of the plurality of voltage converters being configured to convert a voltage of the battery connected to the primary side thereof at an arbitrary transformation ratio and to output the converted voltage to the secondary side;
- and
- a plurality of current measuring devices connected respectively to the primary sides of the plurality of voltage converters, and configured to measure currents flowing on the primary sides,
- wherein, for each of the plurality of voltage converters, the transformation ratio is set so that the current measured by the current measuring device connected to the primary side falls within a first range between a discharge current maximum value of the battery connected to the primary side and a charging current maximum value of the battery.
