edatoakrun (page 7)...BEV batteries have will be an important component of the future grid, but Tesla has pursued policies that will probably make it's products batteries useless for these goals.
There are two major future applications for BEV batteries in grid stabilization/load balancing.
The first is using the BEV batteries while they are in the vehicle.
This requires widespread installation of DC charger/Vehicle to grid devices at useful locations, mostly homes and workplaces.
Tesla instead "Free" supercharger policy, means VtoG is economically impossible.
Sad to say, that huge battery in every S will probably never be available to meet grid demand, not while parked at work, nor while parked in every S owners garage.
Which is part of why Tesla is now trying to sell S owners even more batteries for their garage.
The second application of BEV batteries is in repurposing them is stationary applications, after they lose enough of their initial capacity/energy density to make replacement desirable.
The complexity and cost of using Tesla batteries, which require thermal management for safety reasons, probably makes them a poor choice in most new installations.
IMO, trying to repurpose used S packs for this application involves so many additional challenges, it will probably never happen on any scale.
