- Gwypaas 4y agoI would say no. Your expensive battery on wheels with a complete integrated system is not something you want to abuse. Unless it can take for the entire lifetime of the car without significant degradation. Compare this to racks on land with far less stringent requirements. One the other hand, EVs can fill the same role by simply being smart consumers. You don't even lose any round trip efficiency - because storing energy in the car's battery is the work being done. Consider a future where you can set your car to have at least 60% each morning and then 100% on Saturday, because you are going on a trip. The car will then optimize the charging times for the lowest cost. Thus balancing the grid. Dynamic demand has the same effect on the grid as dispatchable energy. No need to complicate it further.

Deploying dedicated racks-on-land with the proper total capacity and throughput would be a nightmare, without even considering locality. And yes, a "minimal charge-level" parameter will be enforced. Dynamic demand offers low-hanging fruits, and then it becomes more and more a constraint... alleviated by dispatchable energy.
