Patent ID: 8369067

Claim:
An electricity feeding control device, controlling power feeding from an external power source to an electrical automobile comprising a battery and a charge circuit for charging the battery, comprising a housing case as an outer bailey, wherein the housing case is provided in a part of its peripheral wall with an air hole formed by penetrating the part, the housing case provided with an inner pressure adjusting sheet, which is formed with a breathable and waterproof member and is arranged so as to cover the air hole from the inside of the housing case, wherein a channel of the air hole, led from the inside to the outside of the housing case, is formed into a nonlinear shape, wherein the electricity feeding control device further comprises a relay opening and closing a power feeding channel leading from the external power source to the charge circuit; a leakage detection means detecting a leakage based on a current flowing in the power feeding channel; and a control means being configured to switch off the relay to block thereby the power feeding channel when the leakage is detected by the leakage detection means, wherein the housing case houses the relay, the leakage detection means and the control means, and wherein the air hole comprises a long recess formed in an outer surface of the housing case, a communicating hole consecutively formed in one end of longitudinal direction of the recess and communicated with an inner surface of the housing case, and a shielding plate attached in the outer surface of the housing case so as to cover a region other than the other end of the longitudinal direction of the recess, in a region of an opening section of the recess.
