If you consider that EVs have A) large batteries w/ efficient charge/discharge cycles, B) efficient high-capacity inverters, and C) are plugged in (somewhere) for large fractions of their life, and D) very often have capacity far exceeding their next expected trip duration, then:
It is inevitable that Tesla (or someone else) will implement Grid-tied battery backup as a standard option on these vehicles.
When that happens -- the Grid gets "free" multi-GWh battery-based load shedding.
Why is this not considered an inevitability? Am I missing something obvious here?
- jacquesm 11y agoNo, you're not missing anything, that is a very likely thing to happen.
- cdibona 11y agoThis assumes the cars are plugged in when there is the most 'extra' capacity being generated from , say, solar thermal/pv. This is when most cars are out at a workplace, not plugged in. This is also when industrial consumption/ac use peaks, so why would you over produce and feed a battery rather than run a plant/keep places cool...
