New charging approach could extend battery life by at least 20%

The study is published in the journal IEEE Transactions on Control Systems Technology :-

New charging approach could extend battery life by at least 20%

The many cells that make up a lithium battery pack are not all equal; some will degrade and die faster than others. New research out of Stanford has found that the whole battery can live much longer if each cell gets an individual charging treatment.

Its also interesting to see just what the author thinks about fast charging, which I agree with him 100%.

What would the design of a battery BMS which charges each cell individually be?

Awkward!

42 pin nightmare

If all of the cell interconnects and BMS could be disconnected instantaneously (there's at least one way) so that each individual cell can be charged individually in situ within the ebike battery case, after which the cell interconnects and BMS are instantaneously re-connected?

this can monitor every cell but for diy powerwalls
