A CONVENTIONAL BATTERY
70-80% State of Health is a recommended battery end-of-life threshold.
To avoid accelerated cell aging cell balance should be within ±2.5%.
Battery health is as strong as the health of its weakest cell.
A NUBACELL BATTERY
A battery at 50% SoH continues to age gradually, which сan enable an additional 50 percent of charge / discharge cycles.
A 20-30% SoH imbalance in cells is a supported scenario; weaker cells might slightly reduce battery run time.
Although all cells are used one by one, the battery operating voltage remains constant
10A Discharge Cycle
Our battery management adjusts individual cell load patterns based on cell charge and health.
Cells with a lower remaining capacity are subjected to less stress load, allowing for more time to recover voltage and save cycles.
Nubacell fully supports live cell replacement. Any cell can be extracted from a battery on the fly and replaced with the identical or different type of cell, without affecting operational battery voltage. The architecture also supports live battery capacity extension.
Each cell module is polled in a cyclic fashion to determine their current state. Failed cells are disabled automatically at the module level, without involving the BMS. It is performed in real time, which helps reduce potential hazards. In this video, we simulate live cell failure to trigger the system response.
