What is a rechargeable battery state of charge (SOC)?

A rechargeable battery’s state of charge (SoC) refers to its current energy level compared to its optimal capacity, expressed as a percentage. It is similar to a battery fuel gauge, indicating how much charge remains before recharging. The SoC is crucial for monitoring battery health and performance.

What does the percentage of a battery mean?

The percentage of a battery directly reflects its state of charge (SoC). When we say a battery is at 50%, half of its total capacity is available for use. So, if a battery has a total capacity of 100 amp-hours (Ah), a 50% SoC indicates that 50 amp-hours remain. This relationship is straightforward: the percentage represents the SoC. 2.

What does a 50% SoC battery mean?

SoC stands for State of Charge, which is a measure of how much energy is remaining in a battery as a percentage of its fully charged capacity. So, if a battery has a 50% SoC, it means that it has used up 50% of its total energy capacity. SoH stands for State of Health, which is a measure of the overall health and performance of a battery over time.

Should you overcharge or undercharge a battery?

Overcharging a battery can damage it and shorten its lifespan, while undercharging can reduce its capacity and efficiency. By monitoring SOC levels and charging the battery to the correct level, you can avoid these extremes and optimize battery performance.

What is the difference between a high and low Soh battery?

A battery with a high SoH will be able to hold a charge for a longer period of time and will have a longer overall lifespan than a battery with a low SoH. DoH stands for Depth of Discharge, which is a measure of how much energy has been drawn from a battery compared to its total capacity.

What affects a battery's SoC?

Age and degradation: As batteries age and degrade over time, their maximum SoC starts to drop, meaning a 100% SoC for an old battery would be similar to a 75-80% SoC for a young one. Charging and discharging patterns: How a battery is charged and discharged can also impact its percentage, voltage, and SoC.
