  1. This charger is the creation of a resourceful Western Australian Tesla owner, Jon Edwards.

    There are some outback locations – nothing more than a roadhouse, providing food and fuel – which don’t have a grid connection and run entirely off diesel generators.

    They get very little electric vehicle traffic, but they make up a core route between the eastern and western parts of Australia.

    This charging system, tagged “Biofil”, is effectively a self-contained 50 kW fast charger and a generator on a pallet. Left over cooking oil from the roadhouse kitchen is settled in some drums and used to power the generator. There is enough oil used per week for about six fast charging sessions (doesn’t sound like much, but this is significantly more than the volume of traffic – and it can be stored in the off-weeks in case there is a busy week)

    More detail about this unit in this article: https://thedriven.io/2021/01/15/how-biodiesel-ev-chargers-could-connect-remote-locations/

    And there is going to be an “endurance test” of the unit next weekend in Perth. People are welcome to come and see it being used: https://www.facebook.com/AEVANational/posts/10157977064867187

  2. Jon Edwards’ previous experiments with these “charge pods”: https://thedriven.io/2018/12/14/diesel-charge-evs-remote-locations-greener-than-you-think/

    (this being the source of many “hot take” memes about the apparently ridiculous situation of burning diesel in a generator to charge an EV)

    edit: I was busily writing a scathing take-down of people who don’t bother to read the source material before producing hot-take memes, then blaming me for killing their meme when I point out the facts, only to find that the original “charge pod” article is already linked in this article.)

  3. Tbh. in that case I’d rather put that Oil in an old diesel. Do keep in mind I live somewhere electricity is really cheap and diesel costs a fortune

  4. I had a friend that had a big generator like this and would run used cooking oil in to his grid tied house and run the meter backwards.

  5. Wait, isn’t this technically internal combustion generating electricity for a charging station?

  6. Great implementation. Not sure about the accuracy of that circle. What makes the flowers again? The generator?

  7. While it’s a cool concept, that does still release greenhouse gases. Solar + batteries would be cleaner, and could also power the roadhouse.

  8. You mean by burning hydro-carbon? I thought avoiding that was the whole point? I must have missed a memo somewhere…

  9. That’s really cool! I own two cars. One old diesel running on waste cooking oil and an EV. Would love to have a waste oil generator 😀

  10. This isn’t that great, biodiesel still produces carbon emissions. The better solution would’ve been solar (and wouldn’t have really cost much more than that industrial grade generator

    If they’d invest a little bit in solar and some batteries they could completely eliminate their usage of diesel for both the EV charging and running the rest of the roadhouse and probably save a ton of money in the long run (no more diesel bill, no maintenance costs on generators)

  11. The Mercedes 180D can run on cooking oil with minimal modifications. Later Diesel engines are more difficult.

  12. This would be beneficial in areas with low or no sun, like the arctic.

    Downside: carbon emissions.

    upside: closed loop carbon emissions. (aka, pulled from existing ecosystem rather than pulling from an ancient ecosystem and quickly terraforming the planet into a hot house that only cold blooded creatures would love)

    Combine this with a battery system and solar and you can have a station that gets best of both worlds.

    In australia, battery storage systems and solar would make even more sense than this.

    In alaska or the arctic, this would be an even better system, though the oil would need to be treated with anti-gelling compounds.

  13. At least they aren’t trying to power them with Penguin Oil like in the 1800’s
