Abstract
A method and system provide a plurality of power cell modules. The power cell modules can be stacked together such that they are electrically connected and share a collective multi-voltage bus. Electronic appliances can be connected to one of the power cell modules to be powered by all of the connected power cell modules. Power cell modules can be easily added or removed from the bank without interrupting the supply of power to the electronic appliance.
Claims31
A power cell module comprising:
- a casing;
- multiple batteries disposed within the casing;
- voltage combination circuitry disposed within the casing and including multiple voltage outputs each corresponding to a respective serial connection of the multiple batteries, a parallel connection of the multiple batteries, or a combination of serial or parallel connections of the multiple batteries;
- a multi-voltage bus receiving the multiple voltage outputs from the voltage combination circuitry and including a line for each voltage output;
- and
- multi-voltage bus connectors configured to attach the casing to a second power cell module and to electrically connect each line of the multi-voltage bus to a corresponding line of a multi-voltage bus of the second battery pack.

A modular power cell system, the system comprising:
- a first power cell module including:
- multiple first batteries;
- a first multi-voltage bus simultaneously carrying multiple voltages each on a respective line of the first multi-voltage bus;
- and
- first inter-module multi-voltage bus connectors;
- a second power cell module including:
- multiple second batteries;
- and
- a second multi-voltage bus simultaneously carrying multiple output voltages each on a respective line of the second multi-voltage bus;
- and
- second inter-module multi-voltage bus connectors configured to attach to the first inter-module multi-voltage bus connectors of the first power cell module by stacking the second power cell module on the first power cell module, thereby forming a collective multi-voltage bus from the first and second multi-voltage busses in which each line of the first multi-voltage bus is in electrical contact with a corresponding line of the second multi-voltage bus.
8 more elements
A method comprising:
- electrically connecting multiple power cell modules together in a bank of power cells;
- forming, between the modules, a collective multi-voltage bus carried by each of the power cell modules;
- receiving, in a user power output port of a first power cell module of the bank of power cell modules, an electrical connector from an electronic appliance;
- and
- providing, via the user power output port, power to the electronic appliance collectively from each of the power cell modules in the bank via the collective multi-voltage bus.
