Abstract

The present invention describes a charging adapter (110) for charging a vehicle battery (100). The charging adapter (110) comprises a carrier (115) and a charging coil (120) fastened to the carrier (115), the charging coil being designed to generate an alternating charging current in response to a charging magnetic field. The charging adapter (110) also comprises a rectifier (125) fastened to the carrier (115), the rectifier being designed to generate a rectified charging current based on the alternating charging current. The charging adapter (110) also comprises a positive contact (111) fastened to the carrier (115) and a negative contact (112) fastened to the carrier (115), the positive and negative contacts being designed to be plugged into a positive pole (101) and a negative pole (102) of the vehicle battery (100). Furthermore, the charging adapter (110) has lines (121, 122) which are designed to conduct the rectified charging current to the positive contact (111) and the negative contact (112).
