Energy transmission device and Energieübertragungssytem

摘要

The housing (15) of a power transmission device (101) is provided with a power transmitting device side passive electrode (11), an energy transmitting device side active electrode (12), a power transmission module (13), and the like. A terminal-mounted casing is provided with a power receiving device side passive electrode (21), a power receiving device side active electrode (22), a power receiving module (23), a DC-DC converter (24), and the like. A heat sink portion (11S) having a plurality of ribs is formed at a portion of the power transmitting device side passive electrode (11). When the terminal is mounted with the cladding on the power transmission device (101), the power receiving device side passive electrode (21) is electrically connected to the power transmitting device side passive electrode (11), and the power receiving device side active electrode (22) is the power transmitting device side active electrode (12 ). In this state, the heat of the power receiving module (23), the DC-DC converter (24) and the like is dissipated from the power transmitting device side passive electrode (11).
