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 of the type C port and the negative power terminal coupled to the USB type C port at a third node;
a first control module and a second control module; and
a bi-directional non-inverting buck/boost converter coupled between the positive power terminal and the first and the second node of the type C port.

2. The battery pack power transfer adaptor, as recited in claim 1 , further comprising an overvoltage protection module coupled to the adaptor positive power terminal and the adaptor negative power terminal and to a plurality of adaptor signal terminals.

3. The battery pack power transfer adaptor, as recited in claim 2 , wherein the overvoltage protection module is coupled to the second control module.

4. The battery pack power transfer adaptor, as recited in claim 1 , further comprising a first thermistor circuit and a second thermistor circuit to monitor the temperature of the adaptor and its components.

5. The battery pack power transfer adaptor, as recited in claim 4 , wherein the first and second thermistor circuits are coupled to the second control module.

6. The battery pack power transfer adaptor, as recited in claim 1 , wherein the buck/boost converter is coupled to the first control module.

7. The battery pack power transfer adaptor, as recited in claim 1 , further comprising a battery disconnect switch coupled between the buck/boost converter and the positive power terminal.

8. The battery pack power transfer adaptor, as recited in claim 1 , further comprising a USB type A port, the USB type A port including a positive node, a negative node and data node formed as terminals on the port.

9. The battery pack power transfer adaptor, as recited in claim 8 , further comprising a buck converter coupled between the positive power terminal and the positive node of the type A port.

10. The battery pack power transfer adaptor, as recited in claim 9 , wherein the buck converter is coupled to the second control module.
