ABSTRACT:
An apparatus for charging a battery of an electrically powered vehicle located at a charging station is provided. The apparatus comprises a pair of separate primary cores each of which has a primary coil and is disposed in a wheel stop block secured at the battery charging station, and a secondary coil which is carried by the vehicle. The apparatus further includes a first drive mechanism for retractably lowering the secondary coil linearly to its operative positions, and a second drive mechanism for retractably moving the primary cores inwardly toward each other linearly to their operative position where a closed magnetic circuit is formed thereby and the primary coil is inductively coupled with the secondary coil which is then placed in its operative position. Each primary core has a projection which is engageable with a counterpart of the other core, and the engaged projections of the cores are arranged to pass through an opening of a secondary coil case round which opening the secondary coil is wound.
