Lock arrangement and method for transferring electrical power with a lock arrangement that comprises a counterpart (101, 301) of the lock and an electrical lock (102, 202) comprising a lock case (203). Means for wirelessly sending (303) electrical power to the lock case and/or into connection with the lock case (203) are arranged in connection with the counterpart (101, 301) of the lock, and arranged in the lock case and/or in connection with the lock case (203) are means for wirelessly receiving (205) electrical power from the means for sending electrical power that are arranged in connection with the counterpart of the lock. The counterpart (101, 301) of the lock wirelessly sends electrical power to the lock case (203) and/or into connection with the lock case with the means that are for sending (303) electrical power, and the lock case (203) wirelessly receives electrical power from the counterpart of the lock with the means that are for receiving (205) electrical power, when the lock (102, 202) and the counterpart (101, 301) of the lock are at a certain distance from each other. In the method the electrical power received from the connection of the lock is measured and the power level of the electrical power sent is increased and/or decreased in such a way that the measured level of the electrical power received is between certain predetermined upper and lower values or essentially at a given preset level. |
