Hacker with a solution for bidirectional Tesla charging > teslamag.de

tesla laden stecker nah

Nearly 100 kilowatt-hours of battery life in the garage raises wishes: Tesla electric cars can still only be charged, but not statically discharged, although it makes sense for many owners to shut down their home in high mains power conditions. would be an interesting option. Take care of prices or failure. While many other manufacturers do the same Bidirectional charging as V2H (vehicle-to-home) or even V2G (vehicle-to-grid) Explore, Tesla itself has been reluctant to do so until now. But a hacker has now stood up and found a way to extract up to 10 kW from Model 3 & Co. There’s been a lot of interest in it, and now he’s thinking about making a product out of it.

Musk praises Tesla hackers

Jason Hughes is a big name in informed Tesla and hacker circles, as he received indirect Twitter praise from Elon Musk in 2016 and $50,000 a year later for finding a way to use the app at any Tesla reach worldwide. However, he did not take advantage of the gap, but informed the software security chief at Tesla, who quickly took remedial action. Hughes later turned his attention to battery analysis and other discoveries, and this year his company offers 057 Technology Battery Insurance for Older Model S and Model X Feather.

And soon one more may be added to the still short list of 057 products. Because on Friday Hughes reported on Twitter as @wk057 that Tesla electric cars can now be made to emit direct current with about 10 kWh of power. This is done through the normal charging connection in the car without any modifications. So far, his solution for this is still “super dirty”, but it can probably still be optimized.

He maintains the vehicle-to-grid himself, so Integration of electric cars into the power grid, as for “extremely stupid”, @wk057 advised against it in another Twitter message. It sounds ridiculous to waste a battery cycle in your car and probably cost you more (including Tesla warranty) than you can earn in the long run. As the mildest form of vehicle-to-load bidirectional use – an electric car does not supply the entire household, but the individual consumer – it, on the other hand, finds it useful in many respects.

Software update may end V2L

Even his disapproval for V2G was not challenged, and overall Hughes was able to quickly establish that Tesla was very interested in using batteries bidirectionally. Specifically, he was referring to a V2L solution proposed during the discussion: a 10 kW inverter in a box with a few AC outlets. Hughes announced that he now wants to take a closer look at the product’s viability. However, he is concerned that Tesla may buy it and analyze it and then eliminate the option of a stable discharge via a software update.
