Hacker with a two-way Tesla charging solution> teslamag.de

Almost 100 kWh of the battery in the garage gives rise to desires: Tesla electric cars can still only be charged, but not discharged while stationary, although this would be an interesting option for many owners to shut down their homes in the event of a power surge Prices or failure to pay attention. While many other manufacturers are exploring such bi-directional charging as V2H (vehicle-to-home) or even V2G (vehicle-to-network), Tesla itself has so far been reluctant to do so. But a hacker has now found a way to extract up to 10 kilowatts from the Model 3 and co while standing. There is a lot of interest in it, and he is now considering making a product out of it.

Musk praises Tesla hackers

Jason Hughes is a big name in insider Tesla and hacker circles, because in 2016 he received indirect praise on Twitter from Elon Musk and a year later with $50,000 for finding a way to use the app on any Tesla access worldwide. However, he did not take advantage of this gap, but informed Tesla’s head of software security, who quickly took corrective action. Hughes later drew attention to battery analysis and other discoveries, and this year his company, 057 Technology, began offering battery insurance for older Model S and Model X models.

Soon, another product can be added to the short list of 057 products. Because Hughes reported Friday on Twitter @wk057 that Tesla electric cars can now be built to emit a direct current of about 10 kilowatts of power. This is done via the normal charging connection without any modifications to the vehicle. So far, his solution to this is still “too dirty”, but maybe it can still be improved.

He himself considers the car network, that is, the integration of electric cars into the electricity grids, “extremely stupid”, and advised @wk057 not to do so in another message on Twitter. It seems silly to him to waste battery cycles on your own car and it might cost more (including the Tesla warranty) than you can earn in the long run. On the one hand, vehicle loading appears to be the mildest form of two-way use – the electric vehicle does not provide a complete home, but individual consumers – on the other hand, is beneficial in many cases.

Software update may terminate V2L

Even his rejection of V2G did not go unchallenged, and Hughes in general was able to demonstrate a strong interest in using Tesla batteries bidirectional. Specifically, he was referring to a V2L solution he proposed during the discussion: a 10 kW inverter in a box with some AC outlets. Hughes announced that he now wants to take a closer look at the product’s viability. However, he is concerned that Tesla will be able to purchase it, analyze it and then end the hard-discharge option via a software update.
