Charging

Charge car only with solar energy reported from Smart Inverter

Sometimes, we simply want to top up for free using exactly the amount of solar that the smart inverter is generating - "Follow the sun charging". In this way, use all the free energy, but don't burden the grid either - just a nice little top up.

 

Idea can be extended to PowerWall stored energy too.

Charging

Charge a Tesla Vehicle Using Direct Current

Right now, if you want to use your own solar panels directly, you have to convert DC to AC, plug-in the mobile charger, then convert it back to DC again for the battery.

 

Since solar generates electricity as Direct Current, it would be nice to use the on-board inverter or by-pass the conversion completely and just charge the car using direct current.

 

I think we would need a standardized protocol/pins for using DC.

Mobile App

Provide app and/or API access to control the charge current

Third parties are coming to market to allow users control of charging at the moment of the best energy rate during the day.

This gives users the ability to save on charging costs and open opportunities to only charge when home Solar panels are providing energy. Smart Charging in general is becoming more important in balancing the grid and the only way today to integrate a Tesla into this mix is by starting and stopping... more »

Charging

Solar roofs on Tesla cars cockpit

It is about turning internal car "passive" surfaces to "active" = generators. This way, energy is recovered through constant generation where an available light source found.

These materials will have pay back with the generation and during useful life (currently bigger than car life). When current passive surfaces are replaced, the cost could increased but the gap is paying itsleft by free solar energy generated.

Charging

Power wall - use grid to match vampire drain

Power wall drains to zero with internal discharge at about 2% per day. The last two summers my solar panels have gone off line once from grid surge and then from bad connectors (same issue as Wal-Mart lawsuit) and it takes over a month for service or repairs by which point PowerWall has gone to zero allowing no backup power. At that point you just hope National Weather Service triggers Storm Watch in enough time to recharge... more »
