System for location and charging of wireless power receivers

A wireless power transmitter for transmitting laser power to a receiver, the transmitter comprising:

• a laser beam generator adapted to emit a laser beam, the laser beam having at least one scanning mode and at least one charging mode, the at least one scanning mode having:
• (a) a lower power level than any charging mode beam, and
• (b) a beam area, at least at a maximal intended operation range of the transmitter, larger than the area of any charging mode beam,
• the laser beam generator further comprising at least one of:
• electrically insulated connections for powering the laser beam generator, the insulated connections adapted to reduce the likelihood of an inadvertent electrical connection to the laser beam generator, and
• at least one gated switch in each of the electrical connections, for controlling the flow of current through each of the electrical connections;
• a detection element configured to detect if the beam is directed towards a power receiving element of the receiver;
• and
• a controller configured to instruct a laser beam deflector to serially direct the laser beam in multiple directions, and to switch the laser beam generator from emitting a beam having at least one scanning mode to a beam having at least one charging mode when the detection element indicates that the laser beam is aimed in a direction where the presence of a power receiving element is indicated.
