A battery pack that includes an enclosure having at least four sidewalls and a base. An array of cells is arranged on the base, with each of the cells having a large wall surface and a small wall surface. The cells are arranged such that the large wall surfaces are parallel to each other. Components of the enclosure are made from an extrusion process and are mechanically attached or welded together. A base of the enclosure has fluid channels formed from the extrusion for use in cooling the array of cells.

Aspects of the disclosure provide a battery pack and a method for charging the battery pack externally. The battery pack can include a charging port configured to charge the battery pack, a cooling circuit configured to cool the battery pack in a vehicle, and a cooling interface configured to connect the cooling circuit with an external cooling device that is external to the vehicle. The charging port and the cooling interface can be integrated into a charging port assembly, the cooling interface has an inlet port and an outlet port that have high pressure quick disconnect leakless fittings, and the battery pack is configured to be charged externally via the charging port. The battery pack can include a plurality of isolating devices configured to determine whether the cooling circuit is connected to the external cooling device.

A method of producing fuel that includes providing a feed comprising natural gas, a portion of which is renewable natural gas, to a steam methane reformer in a hydrogen production unit. The feed includes a first portion that is converted to syngas and a second portion that passes through the steam methane reformer unconverted. The unconverted feed is directed to one or more burners of the steam methane reformer as fuel. The renewable natural gas is apportioned such that the first portion of the feed, which is feedstock, has a larger renewable fraction than the second portion, which is fuel. Apportioning a higher renewable fraction to the portion of the feed that is converted increases the yield of renewable content.
