AUTOMOBILE CHARGING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an automobile charging device which needs no incorporation of a cooling device therein and nor does cause a breaker tripping or stop charging even when an internal temperature of the automobile charging device increases.

SOLUTION: An automobile charging device 1 charges a charging automobile 2 via a charging cable 3. The automobile charging device 1 includes: a breaker 7 for shutting off a charging path when detecting an excess current on the load side or an earth leakage current; a temperature sensor 20 for detecting an internal temperature of the automobile charging device; and a charge controlling part 10. The charge controlling part 10 includes a pulse output circuit 12 for outputting information of an allowable current value to the charging automobile by a pulse signal, a determination circuit 22 for determining an allowable current value according to the measured internal temperature, and pulse width changing means (current limitation means) 15 for changing the pulse output according to the allowable current value.
