That's what a market is for.

  There is no market. I can only sell electricity to PG&E and only at a flat rate.

    That is a market. You can decide to sell or not. Whether PG&E offers a market clearing price is a separate issue.

  Yeah, I'd try to model the deprecation cost of the battery to some extent while tuning my magic numbers in the trading bot settings. ~1,500 cycles per $16k battery replacement. Shouldn't sell a full cycle for less than ~$15. Don't arbitrage a 1% point of battery life unless it yields at least $0.15. Might just set it at $0.20 per 1% for healthy margin/price-in hassle of battery replacement.

    You're not actually getting the full 100% out of a cycle probably when the utility drains it though. They'll take a portion of your battery then it'll either charge up again using a partial cycle or your car will get charged at home like normal where the math you did is closer. It's also not super clear how much wear small charge discharge cycles does on a normal battery if it's not in the bottom or top 20% of the battery.
