DOE Beats One-Factor Battery Testing
Explain why DOE is better than one-factor-at-a-time testing when battery factors interact.
Changing one knob at a time is simple, but battery systems are not one-knob systems. DOE helps you design the learning before you spend cycler time. The goal is to understand which factors move the response, which combinations matter, and which conditions are safe enough to scale. Factors and levels define the learning space A factor is an input you deliberately vary: charge rate, temperature, upper cutoff voltage, rest time, stack pressure, electrolyte additive, separator type, or formation current. A level is the actual setting tested. Good levels are realistic extremes, not fantasy values that cannot become a process window.…
