Portable and modular energy storage for multiple applications

A method of providing power from a modular energy pack, the method comprising:

• inserting the modular energy pack into a second housing, wherein:
• the second housing is configured to removably receive a plurality of modular energy packs;
• and
• the modular energy pack comprises a first housing comprising a front side and a rear side opposite the front side, and a handle on the front side of the first housing such that the front side of the first housing and the handle are exposed when the first housing is inserted into the second housing;
• monitoring a temperature of the modular energy pack using a temperature sensor;
• collecting, through a processing system of the modular energy pack, power from one or more energy cells enclosed in the first housing of the modular energy pack;
• providing, through an interface of the modular energy pack, the collected power from the one or more energy cells from the processing system to the second housing;
• and
• transferring heat away from the one or more energy cells using a thermally conductive fluid that is circulated from the second housing into the first housing, wherein the processing system controls a flow of the thermally conductive fluid through one or more valves on the rear side of the first housing that are configured to removably mate with corresponding one or more valves on an interior of the second housing when the first housing is inserted into the second housing based on temperature readings received from the temperature sensor.
