Re:EV batteries alone could satisfy short-term grid storage ...

I cannot claim that it is impossible to run a lithium ion battery pack in an EV application without a BMS but I can claim that if you do that it will almost certainly catch on fire. Quote below from (https://batteryuniversity.com/article/bu-908-battery-managem...):
"The purpose of a BMS is to:
1. Provide battery safety and longevity, a must-have for Li-ion.
2. Reveal state-of-function in the form of state-of-charge and state-of-health (capacity)
3. Prompt caution and service. This could be high temperature, cell imbalance or calibration.
4. Indicate end-of-life when the capacity falls below the user-set target threshold.
Not all BMS offer all these features. The most basic functions are battery protection and showing state-of-charge (SoC)."
Without battery protection and while running many hundreds of individual cells your battery will catch on fire. I will bet the house on that. No EV maker would ever make an EV without a BMS.
You have gone beyond ignorance at this point by claiming that you are insulted and asking for an apology. I won't ask you for one, but I will ask for a public correction and acknowledgement that you were wrong.
