SOLAR BATTERY CONTROLLER

摘要

A solar battery controller includes: a solar battery module including a plurality of solar battery clusters and a bypass portion, the plurality of solar battery clusters being arranged side by side in a direction that intersects with a traveling direction of a moving object, the plurality of solar battery clusters being connected in series, the bypass portion being configured to bypass the solar battery cluster to which a light intensity applied has decreased; a light intensity detecting unit configured to detect a light intensity that is applied to a corresponding one of the solar battery clusters, the light intensity detecting unit being arranged ahead of the corresponding one of the solar battery clusters in the traveling direction of the moving object; and a control unit configured to determine a maximum power point of the solar battery module.

1. A solar battery controller comprising:
a solar battery module including a plurality of solar battery clusters and a bypass portion, the plurality of solar battery clusters being arranged side by side in a direction that intersects with a traveling direction of a moving object, the plurality of solar battery clusters being connected in series, the bypass portion being configured to bypass the solar battery cluster to which a light intensity applied has decreased; a first light intensity detecting unit configured to detect a light intensity that is applied to a corresponding one of the solar battery clusters, the first light intensity detecting unit being arranged ahead of the corresponding one of the solar battery clusters in the traveling direction of the moving object; and a control unit configured to determine a maximum power point of the solar battery module, wherein the control unit is configured to acquire a change in the number of bypassed solar battery clusters based on a change in an output of each first light intensity detecting unit, the control unit is configured to shift a start voltage to a first start voltage corresponding to the changed number of bypassed solar battery clusters, and the control unit is configured to determine the maximum power point of the solar battery module by calculating an electric power while changing a voltage from the first start voltage.
