Charge Controller
A Charge Controller is a device that manages how batteries are charged and discharged in energy systems, like those used in solar power setups or electric vehicles. Think of it as a traffic guard for electricity - it makes sure batteries don't get overcharged or drained too much, which helps them last longer. Companies working with renewable energy, battery systems, or electric vehicles often look for people who understand these devices. You might also hear them called "battery management systems" or "charge regulators" in job descriptions.
