Embodiment Construction

[0017] The accompanying drawings, which form a part of this disclosure, illustrate examples of the disclosure. It should be understood that the examples shown in the drawings and / or discussed herein are non-exclusive and that there are other examples of how the present disclosure may be practiced. As used herein, the term "or" means a non-exclusive or (and / or) and may include any combination of the listed items.

[0018] Disclosed herein are methods, devices and systems for modular portable electrical energy storage, wherein each energy storage module has independent electrical and mechanical connections. Multiple energy storage modules can share a common power unit in a stackable configuration, improving portability. Each energy storage module may be electrically and mechanically connected to the electrical device using separate electrical and mechanical connections, eg in a star configuration. The electrical energy storage module may use storage elements such as batteries,...

Abstract

An apparatus comprises a power converter; one or more power supply terminals configured to be connected to a power supply; and one or more load terminals. The apparatus further includes two or more energy storage terminals configured to be connected to two or more electrical energy storage devices. Two or more protection circuits included in the apparatus are electrically connected between the respective energy storage terminals and the power converter, and each of the protection circuits has one protection circuit. The two or more protection circuits are configured to disconnect the respective terminals from the power converter upon failure of the respective one of the electrical energy storage devices.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 955,498, filed December 31, 2019, which is hereby incorporated by reference in its entirety. technical field [0003] This disclosure relates to the field of energy storage. Background technique [0004] Electrical energy storage systems may use storage elements such as batteries, flywheels, fuel cells, thermal storage materials, electrochemical storage materials, flow batteries, and power storage materials. Battery Electricity Storage Systems (BESS) include large systems such as those used in utilities as well as small systems such as mobile chargers. The storage system may be charged from an energy source such as an electrical grid, a solar power system, a wind turbine, mobile solar panels, a generator and / or a turbine. The storage system may release energy to power the load for consumption when an alternate source for the load is, for example...
