主权项

1. An industrial vehicle having a body and carriage selectively attachable to an attachment, the carriage having a range of motion relative to the body, the industrial vehicle having a power supply delivering power to an inductive power transfer unit comprising:
(a) a wireless power transmitter attached to the body and having a first connection that receives power from the power supply; (b) a wireless power receiver spaced apart from the wireless power transmitter, the wireless power receiver receiving wireless power inductively from the wireless power transmitter, where the wireless power receiver is moveable with the carriage such that the amount of wireless power received inductively from the wireless power transmitter does not change as the carriage moves over a range of motion of the carriage, the range of motion greater than the longest dimension of the wireless power transmitter, and where the wireless power receiver has a first connection to a battery on the attachment and a second connection to deliver operating power to a load positioned on the attachment and outside of the housing of the wireless power receiver; and (c) a controller in a housing of the wireless power receiver capable of (i) using said wireless power to power the load; and (ii) using power from the battery to power the load.
