Just charge EVs, and then discharge them during the afternoon and evening.
Peak energy prices are approximately double that of off-peak.
For example, if 50% of a standard Tesla 3 battery could be reserved for this, 31kWh, you could make about $8 per day, or $2,900/year, plus be contributing hugely to grid stability.
It could be as simple as setting cars to discharge back into the grid any remaining power from 4PM-8PM (depending on user preference), and charging from 11PM - 7AM.
It seems totally reasonable for regulators, grid operators, carmakers to collaborate and create standards and mechanisms for car owners to charge and discharge based on their typical driving needs and live pricing.
Look at the enthusiasm for GPU mining - people will flock to getting their cars to do this.
- moogly 5y agoA Tesla battery is only good for ~1500 full charging cycles though.
- Factorium 5y agoThe car is charging and discharging daily anyway. The key is just to do it at certain times. If people can make serious money from the vehicles just from charging/discharging, there's also a big motivation to design batteries with longer lifecycles.
- moogly 5y agoI mean, charging at specific times makes total sense, I totally agree (and there are currently (heh) ways to do that). But for vehicle-to-grid discharging, I'm not sure if the economics make sense. Someone smarter than I would have to do the calculus, but it's quite difficult to put a pricetag on the utility of actually driving the car.
