Create arrays of serially connected, switched cell modules
Switch cells simultaneously to keep constant the number of loaded cells and resulting voltage
- Load initially stronger cells until they are on par with weaker cells
- Inactivate the weakest cells to avoid load stress and save cell cycles
- Faulty cells will self-deactivate to improve battery resiliency
- Change active cell count to stabilise or regulate battery voltage
Continuously monitor each cell to adjust load pattern and predict potential failures
Enable users to replace live modules and upgrade batteries
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
