Abstract: An energy device control system may include an energy source enclosure that can be coupled with external loads via first external connectors outside of the energy source enclosure. The system also may include an external control device coupled with the energy source enclosure via second external connectors such that the external control device is galvanically isolated from energy device cells inside the energy source enclosure. The external control device may communicate with internal control components of the energy source enclosure via the second external connectors to control charging and/or discharging of the device cells via the first external connectors.

Abstract: A system includes an auxiliary battery configured to be disposed onboard a vehicle having an electrically powered propulsion system that is configured to also be powered by detachable main batteries, and a converter configured to be electrically coupled with the auxiliary battery and the propulsion system of the vehicle. The converter is configured to direct electric energy stored in the auxiliary battery to the propulsion system for powering the propulsion system while the vehicle is detached from a depleted detachable main battery and before the vehicle is connected with a charged detachable main battery.

Abstract: Various methods and systems are provided for a vehicle. In one example, a vehicle comprises a first fuel tank configured to store a first fuel, and a second fuel tank configured to store a second fuel, both the first fuel tank and the second fuel tank disposed in the vehicle, a multi fuel engine disposed in the vehicle, the multi fuel engine configured to combust the first fuel and the second fuel, a fuel injection system configured to inject the first fuel into the multi fuel engine, and a conduit configured to route the second fuel from the second fuel tank to the multi fuel engine.

Abstract: Various methods and systems are provided for supplying gaseous natural gas to a rail vehicle. In one embodiment, a method of receiving fuel for use by a first vehicle comprises sending a request from the first vehicle to a remote liquid fuel container to convert a portion of the fuel in the liquid fuel container that is in a first, liquid phase from the first, liquid phase to a second, gaseous phase.

Abstract: Various methods and systems are provided for a rail vehicle. In one example, a rail vehicle includes a first engine positioned in a central location of the rail vehicle, the first engine configured to combust at least one of a first fuel or a second fuel. The rail vehicle further includes a fuel tank positioned in place of an operator cab, the fuel tank configured to store the second fuel.
