Multiple Choice

State of Charge (SOC) and State of Health (SOH) differ how?

SOC tells you how full the battery is right now, expressed as a percentage of its rated capacity. It’s like a fuel gauge for stored energy at that moment. SOH, on the other hand, describes the battery’s overall condition and its ability to perform relative to a new battery. It accounts for aging, degradation, and changes in maximum capacity and internal resistance over time. So you can have a high SOC (battery appears near full) but a degraded SOH (the battery can’t deliver as much energy as a new one), or a lower SOC with decent SOH if the battery is aged but still capable. The two measures describe different things: current energy level vs overall health and remaining performance.
