Abstract

A battery pack power transfer adaptor and a battery pack system that includes a battery pack adaptor. The adaptor enables a battery pack to provide high level power transfers to a variety of devices and to receive high level power transfers from a variety of power sources. The adaptor includes a battery pack interface to enable the adaptor to mechanically and electrically connect to the battery pack. The adaptor is able to transfer power at a variety of levels dependent upon the device to which it is attached.

First claim

The invention claimed is:

1. A battery pack power transfer adaptor, comprising:
a USB type C port;
a set of power terminals including a positive power terminal and a negative power terminal, the set of power terminals configured to mate with a rechargeable battery pack for transferring power to and from the battery pack;
the positive power terminal coupled to the USB type C port at a first node and at a second node and the negative power terminal coupled to the USB type C port at a third node;
an ideal diode coupling the positive power terminal to the first node and a switch coupling the positive power terminal to the second node.

2. The battery pack power transfer adaptor, as recited in claim 1 , further comprising a housing, the housing including an interface for mating with the battery pack.

3. The battery pack power transfer adaptor, as recited in claim 2 , wherein the interface includes a receptacle for receiving the battery pack, the receptacle including the set of power terminals.

4. The battery pack power transfer adaptor, as recited in claim 1 , further comprising a first control module coupled to the switch coupling the positive power terminal to the second node, wherein the first control module controls the switch.
