What happens when cells are not manufactured to the same quality standard or subject to cell grading and testing? Power management innovator Chris Hale of of Chimera Energy looks at the impact on battery packs of cell-to-cell variation and what the differences are between the grades.
It is well understood how lithium-ion batteries can be highly reactive and susceptible to thermal runaway events or even catastrophic failures. It is perhaps less well understood how significant cell-to-cell variations at the manufacturing level dictate overall battery life, reliability and safety . . .
