🔋 Adding new battery modules does not automatically mean you get all the new capacity.
After BESS augmentation, new and old battery modules may have very different capacity, state of health, impedance, and degradation levels.
When they are combined in the same series string, the weakest module can limit the usable capacity of the entire string.
This is where mixed-age string design becomes critical.
A good augmentation strategy should consider:
⚡ Capacity mismatch
🔋 State of Health (SOH)
🌡️ Internal resistance and thermal stress
⚙️ BMS cutoff settings
🧠 EMS dispatch priority
🔌 Whether to segregate old and new modules into separate stringsNew modules may have much more usable life remaining—but poor electrical grouping can leave part of that capacity unused.
