Power Battery Primer — From Cell Chemistry to Grid-Scale Storage and the BMS

A battery isn't a "power plant that stores electricity" — it's a piece of power equipment that shifts supply and demand across time. This article works through cell voltage, capacity, and C-rate, SOC/SOH, thermal runaway, safety design, grid-scale storage and V2G, and cutting-edge research such as solid-state batteries, with the math and charts.

Power Systems 101 — Reading Generation, Transmission, and Storage as One System

Hydro, thermal, nuclear, solar, and wind look nothing alike if you only compare generation methods. This piece reads frequency, supply-demand balancing, substations, transmission losses, batteries, and protection relays as a single power system, walking through the equations that determine output and stability, the equipment in service today, and where renewable-energy research is headed.
