๐ฆ๐๐ฎ๐๐ฒ ๐ผ๐ณ ๐๐ฒ๐ฎ๐น๐๐ต (๐ฆ๐ผ๐) is a metric that reflects the overall condition of a battery compared to when it was new. It typically indicates how much of the original capacity, power delivery, or performance the battery can still provide.
SoH is influenced by several factors, including the number of charge/discharge cycles, exposure to extreme temperatures, storage conditions, and natural aging. A lower SoH means the battery stores less energy or delivers less power than it originally couldโeven if it is fully charged.
Because SoH tracks long-term degradation, it is primarily used for ๐ฟ๐ฒ๐ฐ๐ต๐ฎ๐ฟ๐ด๐ฒ๐ฎ๐ฏ๐น๐ฒ ๐ฏ๐ฎ๐๐๐ฒ๐ฟ๐ถ๐ฒ๐, where monitoring health over time is essential.
SoH is often confused with ๐ฆ๐๐ฎ๐๐ฒ ๐ผ๐ณ ๐๐ต๐ฎ๐ฟ๐ด๐ฒ (๐ฆ๐ผ๐), but they refer to different characteristics:
-
๐ฆ๐ผ๐ indicates how much charge is currently available โ applicable to both rechargeable and non-rechargeable batteries.
-
๐ฆ๐ผ๐ indicates how much of the batteryโs original performance remains โ mainly relevant for rechargeable batteries.
