Charging station, charging system and method for inductive charging
First Claim
1. A charging station for inductive charging of an electrical device having a rechargeable battery and a receiving induction coil, the charging station comprising:
- a housing comprising a plurality of orthogonally oriented panels forming an interior volume arranged to host the electrical device;
first, second, and third pairs of primary transmitting induction coils, wherein the first, second and third pairs of primary transmitting induction coils are orthogonally oriented; and
a controller configured to excite, in sequence, the first, second, and third pairs of primary transmitting induction coils with charging current, wherein exciting in sequence comprises activating only the first pair of primary transmitting induction coils for a first period of time, activating only the second pair of primary transmitting coils for a second period of time subsequent to the first period of time, and activating only the third pair of primary transmitting coils for a third period of time subsequent to the second period of time;
wherein each panel of the first, second, and third pairs of primary transmitting induction coils is arranged at a separate panel of the housing.
