Energy
In physics, energy (from Ancient Greek ἐνέργεια (enérgeia) ''activity'') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not …

Battery Management Systems (BMS)
the energy in higher SoC cells is simply dissipated as heat during balancing, thus, having an impact on system efficiency. b. Active balancing involves the use of dedicated circuitry to transfer charge between cells. One advantage of active balancing is energy in cells with a higher SoC can be moved to cells with a lower SoC and not wasted as heat.

Fuel Cell Basics | Department of Energy
A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode. In a polymer electrolyte membrane fuel cell, a catalyst separates hydrogen atoms into protons and electrons, which take ...
