And is that actually worth it to anyone who does the math? An optimistic 161 pound saving compares to how many of my battery cycles for example? My car costs 50-60k so battery degradation is not nothing.
I did a quick fag packet calculation and even today 10% of everyones EV battery would be enough to cover the grid for an hour. That's enough of a buffer to spin up gas turbines for example, so you can actually shut them completely off.
My Hyundai Ionic 6 rolling battery costs 50-60k. Spending a cycle of it's battery is not a discardable cost.
Some will still take it but this seems just like a more deceptive version of those uber driver that get a pricey car and then find out that combined with maintenance, degradation/devaluation and other hidden costs they don't actually make that much driving around.

I presume you deduct more than half of the rolling battery capacity out there. You can't discharge those to 0% shouldn't charge them to 100%, many won't be charged fully (or connected) + If I need to leave in the morning like most I don't want to necessarily be dropping charge into the grid.
