PROBLEM TO BE SOLVED: To provide a charge control apparatus which is applied to a charge system that charges generation power of a solar panel 18 to a main battery 14 and which can improve charge efficiency at the time of charging the generation power to the main battery 14.SOLUTION: The generation power of the solar panel 18 is once charged to a sub-battery 22. When the sub-battery 22 is charged and the main battery 14 is not charged, charging rate of the sub-battery 22 is estimated on the basis of output current and output voltage of a step-down chopper circuit 24a. On condition that the estimated charging rate exceeds a prescribed value, charge of the main battery 14 is started. At this time, power feeding is controlled to a plurality of electronic devices so that a plurality of electronic devices in which power is supplied when the main battery 14 is charged and which include an MBECU 16 or the like may include an electronic device in which power supply is interrupted when the sub-battery 22 is charged and the main battery 14 is not charged. |
