  • Patent number: 12263744
    Abstract: An electric vehicle charging plug that comprises at least one temperature sensor for monitoring an internal temperature of the electric vehicle plug. The electric vehicle charging plug further comprises a data cable conveys temperature data to a physically separate controller. The electric vehicle charging plug further comprises a housing or holder for receiving the at least one temperature sensor, wherein the housing is capable of being embedded within an inner-mold of the electric vehicle plug. A first seal seals a junction between the at least one pin/blade and a faceplate or bridge plate. A second seal seals both a junction between the at least one pin/blade and a faceplate or bridge plate and the inner-mold. A third seal provided by the inner-mold seals the entire interior of the electric vehicle plug.

  • Patent number: 11258209
    Abstract: A sealed electrical plug comprises at least one temperature sensor for monitoring an internal temperature of the electrical plug. The electrical plug further comprises a data cable that is wrapped by a shield for screening electrical noise so as to accurately capture and convey temperature data. The electrical plug further comprises a housing or holder for receiving the at least one temperature sensor, wherein the housing is capable of being embedded within an inner-mold of the electrical plug and positioned close to at least one pin. One or more seals may be placed at junctions between the at least one pin and the inner-mold and a cable for the data cable to seal the inner-mold from air, moisture and particles.
