Abstract
A system architecture for grid electrical energy storage comprising substantial numbers of cells connected in parallel. The lowest level of modularity comprising about eighteen or more individual cells connected in parallel. The disclosed architecture reduces the number of parts, complexity, and variability, while increasing one or more of reliability, service life, and energy capacity of a large-scale grid energy storage system, relative to a conventional multi-parallel string architecture.
