Transport system for convertible battery pack
First Claim
1. A removable, secondary battery pack for providing electrical power to an electrical device, the battery pack comprising:
- a primary housing configured with a mechanical interface to mechanically couple the battery pack to each of a plurality of electrical devices within a system of electrical devices, wherein each of the plurality of electrical devices within the system of electrical devices includes a housing configured with a mechanical interface to mechanically couple the electrical device with the battery pack;
sets of electrically connected battery cells housed within the primary housing;
a switching network housed within the primary housing having a first state in which the sets of battery cells are electrically connected to each other and a second state in which the sets of battery cells are electrically disconnected from each other; and
wherein, the battery pack being decoupled from the electrical device, a mechanical coupler that causes the switching network to convert between the first state and the second state.

Abstract
A battery pack and transport coupler for enabling the battery pack to reduce the pack power capacity. The battery pack include a plurality of strings of battery cells and a switching network for coupling and decoupling the strings of battery cells from each other. When the plurality of strings of battery cells are coupled together in a default configuration the transport coupler includes a decoupler for decoupling the strings of battery cells and when the plurality of strings of battery cells are not coupled together in a default configuration the transport coupler includes a coupler for coupling the strings of battery cells for operation with an electronic device such as a power tool.
