Abstract

A transportable electrical energy storage system includes an electrical energy storage unit, an electrical energy storage unit management system operably associated with the electrical energy storage unit, an AC/DC rectifier operably associated with the electrical energy storage unit management system, and a DC/DC converter operably associated with the electrical energy storage unit management system. The system further includes at least one bi-directional adapter operatively associated with the electrical energy storage unit and a case for protecting the electrical energy storage unit, the electrical energy storage unit management system, the AC/DC rectifier, the DC/DC converter, and the at least one bi-directional adapter.

Claims

1. An electrical energy storage module charging device, comprising:

an electrical energy storage module charging and management system configured to receive electrical power from an external source;

an insert defining at least one cavity;

a positive female contact exposed into a first side of the cavity;

a negative female contact exposed into the first side of the cavity;

a positive male contact exposed into a second side of the cavity; and

a negative male contact exposed into the second side of the cavity;

wherein the contacts are electrically coupled with the electrical energy storage module charging and management system; and

wherein the contacts are configured to mate with corresponding contacts of an electrical energy storage module.

2. The electrical energy storage module charging device of claim 1, further comprising:

an AC/DC rectifier operably associated with the electrical energy storage module management system; and

a DC/DC converter operably associated with the electrical energy storage module management system.

3. The electrical energy storage module charging device of claim 1, further comprising:

grooves extending from the at least one cavity for receiving corresponding protrusions of the electrical energy storage module.

4. The electrical energy storage module charging device of claim 1, further comprising:

protrusions extending into the at least one cavity for reception in corresponding grooves of the electrical energy storage module.
