Abstract:
A bidirectional power converter circuit is controlled via a hysteresis loop such that the bidirectional power converter circuit can compensate for variations and even changes in transmit and receive coil locations without damaging components of the system. Because the bidirectional power converter is capable of both transmitting and receiving power (at different times), one circuit and board may be used as the main component in multiple wireless power converter designs. A first bidirectional power converter is employed in a sealed battery unit having no external electrical contacts. A second bidirectional power converter is employed in a corresponding cart bidirectional power converter assembly. The battery unit and the cart bidirectional power converter assembly cooperate to wirelessly transmit power from the battery unit to a load of the cart bidirectional power converter assembly and from a power source to the battery unit via the cart bidirectional power converter assembly.

Claim (Index 9):
A cart bidirectional power converter assembly comprising:\n a cradle configured to receive a battery unit; a permanent magnet configured to be in proximity with a digital hall effect sensor of the battery unit when the battery unit is in the cradle; a coil configured to be aligned with a coil of the battery unit when the battery unit is in the cradle; a bidirectional power converter connected to the coil and configured to receive power from the battery unit via the coil when the battery unit is in the cradle, a bidirectional power converter of the battery unit is in a transmit mode, and the bidirectional power converter is in a receive mode; and to provide power from a DC input of the bidirectional power converter to the coil when the bidirectional power converter is in a transmit mode; a power distribution assembly configured to:\n provide power from a DC output of the bidirectional power converter to a load of the cart bidirectional power converter when the power distribution assembly is not connected to a power source; \n provide power from the power source to the DC input of the bidirectional power converter and to the load when the power distribution assembly is connected to the power source; and \n provide a mode signal as a function of whether the power distribution assembly is receiving power from the power source; and \n a microprocessor connected to a directional control of the bidirectional power converter and to the power distribution assembly, wherein the microprocessor is responsive to the mode signal from the power distribution assembly to set a mode of the bidirectional power converter to a transmit mode when the power distribution assembly is receiving power from the power source and set the bidirectional power converter to a receive mode when the bidirectional power converter is not receiving power from the power source, and wherein the microprocessor is configured to communicate with a microprocessor of the battery unit to set a mode of the bidirectional power converter of the battery unit to a transmit mode when the power distribution assembly is not receiving power from the power source and to set the mode of the bidirectional power converter of the battery unit to a receive mode when the power distribution assembly is receiving power from the power source.
