Autonomous battery charging and discharging is accomplished using a load shaping signal, e.g., an optimized load shaping (OLS) signal, as specified in American National Standard ANSI / SCTE 267 2021. A battery charge controller connected to the power grid, microgrid, or nano grid autonomously interprets the load shaping signal and takes local action to charge / discharge without requiring two-way communications, signing-up, or opting-in to a network or cloud-provided service. The system makes it possible for the same load shaping signal to be used not only by all types of electric loads but also by all types of batteries.

The present invention relates to a circular molybdenum nanogrid sample support having an upper and lower dual silicon post structure and belongs to the field of high-precision sample support technology used in electron microscope analysis equipment. The sample support of the present invention has a structure in which two circular molybdenum (Mo) bodies are precisely interlocked and joined, and within this structure, silicon (Si) posts of various shapes are arranged at the upper and lower portions, respectively. Through this upper and lower dual silicon post structure, two samples can be simultaneously fixed and TEM, SEM, or FIB analysis can be performed using a single loading process, thereby maximizing analysis efficiency. Furthermore, the uppermost portion of the silicon posts can be processed into a flat or D-cut shape; this D-cut shape may or may not penetrate downwards, and allows for uniform or non-uniform shape distribution between the posts, enabling adaptation to various sample shapes and analysis purposes. The circular molybdenum nanogrid sample support of the present invention simultaneously secures high mechanical strength and conductivity, and enables precise mass production through semiconductor process-based MEMS technology.
