CHARGING CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a charging control device capable of preventing a discharge phenomenon of a battery which can occur at the time of reverse connection of the battery with a simple circuit configuration.SOLUTION: A charging control device which can be applied to a motorcycle 1 having cranking means 71, 72 for cranking an engine 32 without using power of a battery 17 includes an on signal invalidating circuit part 80 for invalidating an on signal at the time of reverse connection in which a minus terminal 61 is connected to a positive electrode terminal 17a of the battery 17 and a plus terminal 64 is connected to a negative electrode terminal 17b. The on signal invalidating circuit part 80 includes a transistor 81 which is turned into an opened state at the time of positive connection of the battery 17 and turned into a closed state at the time of reverse connection of the battery. The transistor 81 is connected to a bypass circuit part 97 which is branched from a charging control signal line 82 and connected to the plus terminal 64.
