Hello,
I am trying to figure out the best option for adding a non-Tesla EV to our current setup. We have currently have a Model 3 Standard Range Plus that charges via the Mobile Connector connected to a 14-30 outlet in our garage. We used a dedicated 30A breaker here as we were worried about the overall load on the subpanel. We don't drive a ton, don't frequently need to charge from 0-100%, and always have a nice eight hour window overnight to charge at low rates (and could occasionally charge at higher rates when necessary). This works fine for us, but we just added a MINI Cooper SE (BEV). We need to park the MINI outside so we can't rely on the 14-30 outlet. We aren't ready to spend a lot on a service upgrade or complex electrical work at this point, but want to make a smart investment that will work if we do make upgrades down the line.
I was thinking of having an electrician run a split line (?) from the 14-30 circuit across the garage and to the outside, where I can install an EVSE for the MINI. To minimize short-term cost, I was thinking of purchasing two power/load sharing EVSEs - one for the Tesla in the garage and the other outside for the MINI. I know that the Tesla Wall Connectors can power share, but only if they are the same type, i.e., I can't get a Tesla WC for the Tesla and the new Tesla J1772 WC for the MINI. I could, however, get two Tesla WCs or two Tesla J1772 WCs that would communicate and then use an adapter on one of the cars. Or I could look at two JuiceBox or WallBox EVSEs. The JuiceBox solution seems very attractive as it can plug into a 14-50 outlet (increasing portability and reducing the need for an electrician) and the boxes communicate via wifi (and thus not needing a communication wire to run across the garage between the two EVSEs). We'd then use a J1772 to Tesla adapter to charge the M3.
I realize that sharing the 30 amp circuit is not optimal, especially in cases where the cars are both charging. If we can usually add at least 100 miles overnight to each car, I would be happy. In the long-term we could provide more power while still keeping the cars while leveraging the same circuit (saving $).
- Has anyone done anything like this? If so, what is your experience?
- If both cars are charging and the juice is split, 50/50, how many mph would I get on the M3? (~11? That is good enough)
- Any issues with using an adapter to charge regularly like this?
- Any reason to go with the Tesla EVSEs vs. JuiceBox???
Thanks so much for your assistance here. Much appreciated!
