Many embodiments involve rechargeable battery assemblies that are forklift-battery-sized but that comprise multiple built in battery modules. A housing typically contains battery modules installed within the assembly as the assembly is typically symmetrical in configuration. Each battery module has an integrated battery supervisor system (BSS). A Battery Operating System Supervisor (BOSS) module processor serves as a battery management system for all the battery modules. The BOSS module grants permissions to battery modules to enable them to connect and disconnect from busbars at the appropriate times to prevent electrical issues. As a result of various combined features, many embodiments are able to optimize cycle-to-cycle discharge potential of the overall assembly through the use and control of one or more solid state relays associated with each module and that are controlled to connect or isolate the cells of the module from the larger assembly, particularly to isolate the cells if the module is discharged to or below a minimum charge threshold for that particular module.

This invention provides a separate seawater discharge potential energy recovery and power generation system, including a seawater discharge pipe, a potential energy recovery pipe, a potential energy conversion component, a first valve, and a controller. Both the seawater discharge pipe and the potential energy recovery pipe are connected to an offshore platform. The seawater discharge pipe is arranged horizontally, and the potential energy recovery pipe is arranged vertically below the seawater discharge pipe. A first bypass port with a downward opening is provided on the seawater discharge pipe, located directly above the top opening of the potential energy recovery pipe. The potential energy conversion component is disposed inside the potential energy recovery pipe and is used to convert the potential energy of the seawater into electrical energy. The first valve is located at the first bypass port, and the controller is used to control the opening and closing of the first valve. In this separate seawater discharge potential energy recovery and power generation system, the seawater discharge pipe and the potential energy recovery pipe are separately arranged, and the addition of the potential energy conversion component will not affect the normal seawater discharge operation of the seawater discharge pipe.
