CHARGE CONTROL DEVICE AND CHARGE CONTROL METHOD

摘要

A charge control device provided with: a first battery (20) which supplies power to a first load of an auxiliary machine system; a second battery (14) which supplies power to a second load; a first power converter (21) which is used when the second battery (14) is charged from the first battery (20); a second power converter (13) which is used when the power is supplied to the second load; and a control unit (7) which performs start determination control in which the first power converter (21) is not started when the charging rate of the second battery (14) is determined to be larger than a predetermined charging rate threshold value, and the first power converter (21) is brought into a startable state when the charging rate is determined to be less than or equal to the charging rate threshold value.
