Title:
SOLAR PHOTOVOLTAIC POWER GENERATION SYSTEM, VEHICLE, SOLAR PHOTOVOLTAIC POWER GENERATION SYSTEM CONTROL METHOD, AND COMPUTER READABLE RECORDING MEDIUM HAVING RECORDED THEREIN PROGRAM FOR CAUSING COMPUTER TO EXECUTE THAT CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2008/018250
Kind Code:
A1
Abstract:
A charge control ECU (40) halts a charge converter (20) periodically or at a predetermined timing,
and uses a voltage sensor (50) to determine an open-circuit voltage of a solar
battery (30). The charge control ECU (40) then uses a predetermined relational expression
or map to decide, based on the determined open-circuit voltage, an operational
voltage such that the output power of the solar battery (30) becomes its maximum
one. The charge control ECU (40) sets the decided operational voltage, as a target
voltage (VR), to the charge converter (20) and then causes the charge converter
(20) to resume its operation.
