The thermal runaway can increase the risk of fire hazards in a cell and subsequently initiate a chain reaction, thus, making the Li-ion battery pack and the EV unsafe to drive. The internal members are used for making a grid for module placement but they also increase the strength and physical stiffness of the base while also isolating modules from each other in case of fires. And how to capitalize on that? 3 WAY SWITCH SETTINGS. Lead acid battery boiling during charging: this is bad, right? Your point can be very easily made differently. You can get away with a ton of stuff in everyday consumer life, but if you are trying to guarantee some performance of your device/product you can't break the rules (unless you're damn good) - this is why all those backup batteries got changed: They would probably still work fine to ~90% of the spec, but when the power goes out on a winters day 3 years from now, and that over-spec discharge event has pushed the batteries too far down the curve, and instead of having the specified 30 minutes in hand to get the power restored, the equipment unexpectedly goes offline 10 minutes early, crashes the network, and puts the whole system down for a day because the restore-from-dead situation is 10x worse than the "controlled shutdown" you're going to look like a right prat, and someone's lawyers are going to be knocking on your door. With this peice of information you could esitmate battery's internal resistance that is generally better correlated with depth of discharge. Sci-fi episode where children were actually adults. Protecting a battery charger from reverse polarity. @Agent_L: I wonder how much life would be left in the stronger cells of a typical pack when the weakest ones fail, and whether someone with a good supply of identical "failed" battery packs might find it worthwhile to evaluate the cells therein and combine the better cells into packs.
