My understanding is that the BMS monitors voltage and temperature of each cell. Does it also monitor current for each cell? If there is a fault, either in charge or discharge, can the BMS isolate an individual cell from the battery circuit? That would seem to take a lot of power transistors to selectively take a cell out of the circuit and bypass it; and parasitic voltage loss in the transistors all the time. In pictures of the Tesla batteries, it looks like the cells are connected with a simple buss-bar from cell-to-cell, no isolation possible. I am particularly interested in the Chevy Bolt, any BMS info specific to it would be appreciated.
