摘要： The wireless management system for energy storage systems includes a plurality of smart cells arranged into a two-dimensional array and a plurality of distributed management units. The smart cells and management units communicate with each other wirelessly via capacitive coupling (not radio). The communication links have extremely short range (typically under 3 mm), are relatively directional, and are electronically-steerable in the plane of the array. The smart cells may also include at least one power resistor and switch for passive cell balancing. The circuitry in the smart cells is typically incorporated into a flexible sheet that wraps around the energy storage device like a label. This system is extremely reliable because it is massively redundant, fault tolerant, and eliminates the wires used in conventional monitoring systems.

摘要： A method of managing an energy storage system that includes a plurality of smart energy storage cells, and a related method of operation for said smart cells. The cells are arranged into a two-dimensional array, and at least one management unit for controlling and monitoring the smart cells is coupled to the array. The smart cells and management units engage in wireless communication that has relatively short range and is relatively directional, with the direction being electronically-steerable in the plane of the array. The management method assigns direction codes to each smart cell which the cells utilize to steer the directions of their communication links, thereby organizing the smart cells into a plurality of serially-linked communication networks. The methods include steps for automatically determining the size and arrangement of the array, including the orientation of each smart cell. The methods also include steps for automatically reorganizing the network links in response to any cell or management unit failing to communicate, thereby making the energy storage system highly fault-tolerant and extremely reliable.
