Abstract: Disclosed herein are various mobile battery powered beverage distribution and marketing carts, kiosks, systems, and methods for operating, transporting, charging, maintaining, optimizing, and storing these mobile battery powered beverage distribution and marketing carts. The mobile battery powered beverage carts may generally comprise a wheeled base, upper workstation, at least one storage and/or refrigerated compartment, a battery, and a large viewing screen for displaying marketing and/or entertainment content thereon. The battery within the cart is configured to operate any electrical componentry on the cart, so that the cart can be independently operable away from any electrical wall outlets. These carts can be customized with any number of options or accessories to meet particular demands and be temporarily deployed to areas where demand, or crowd size, is highest.

Abstract: Systems and methods for operating an add-on battery that may be electrically coupled to a second system that includes an electrical energy storage device are presented. In one example, the systems and methods provide for extending operation of the second system via selectively powering the second system via the add-on battery in response to operating conditions of the second system.
