So they kind of keep track of incomings and outgoings which may drift in time. So what they are trying to prevent is cars stopping with say 15% indicated charge.

    By charging to 100 they are calibrating the BMS. LFP don't mind being fully charged hence the recommendation.
    Yep, exactly right. We set our BESS systems to usually charge to 90% on each cycle which can be 4 or 5 times a day depending on the site. We have an exercise clock set internally in the BMS to take this to 100% once every 2 weeks - it will run the Gen until the BMS drops into float then resets the battery percent to 100. They do drift due to small errors in the calculations with current in and out over time. They can get 10 or 15% out in a month or so if left to only go to 90%.

    An almost every day occurrence for Diesel trucks. It didn't look like that was overly easy to extinguish...

    Maybe for very old dunger diesel trucks but not brand new ones.

    EV general discussion

    Yes, both ICE and EV vehicle catch fire, for me itís more about how hard an EV fire is to put out, how much hotter it burns and how toxic the smoke is.

    Canít imagine this has helped Janusís business as both Janus and Cement Australia have been on the front foot spruiking this thing recently. Bet they go quiet for a bit now although I see the truck in question is still on Janusís website - they probably should have pulled that part of their site for a bitÖ

    Do you guys realise that this is the second Janus truck that has gone up.
    Cadogan has the details.

    hmmm- Diesel superphosphate truck fire or world trade centre bomb? IT was a big bang John!

    back to ev ing Queenscliff, Ballarat now to Port Fairy. Reversing course in a few days. Suspect I drove an electric car past 20ish or more Wind Farms. I attempted to measures several HV transmission lines again. Not anti electric clearly in a EV! The price of our power is NOT cheaper due to free wind or free sunshine! The twits who claimed it would be should be standing with flags at each of those huge windmills. Or a DUNCE hat on!

    We are lucky in our small state to have almost short HV transmission line distances!! The $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ I drove past today are paid for by


    The new MG is like the prior one not even remotely close to its range statement of 470KM. It may be in the city. It does last twice as long as the prior one and OMG Charging if needed and it wasn't in Marybough, Avoca, Beaufort and Port Fairy. The Charge points are growing faster than rabbits at the moment. All except Ballarat are 50kWh. All good until the next gen arrives in 2025 and beyond! The US based Solid State battery company jumped 14% last night. Note it is $60 less than I sold them for! Not a investment tip!

    My current cheap EV can charge are 170ish kWh. The solid state battery may be 10 time that! Not enough time to get a coffee IF the charge capacity is available!

    Car got a 1500 km service in Ballarat. It was a free check! The Next service is 40,000 km! Should I be worried

    Sure,but that tuck was only carrying cement.

    If the MG range is that bad compared with the specs,isn't it false advertising?

    Not long ago a guy took i think it was Mitsubishi to court as he could not get the specified fuel usage out of his new vehicle and won.

    It was an ICE vehicle though.

    Made some pretty big holes in some stone in QLD using Nitropril and some gelignite, James. Thing is, you could do pretty much anything to the stuff with little risk. Needs a detonator to set it off, and most folk don't carry those in their Kenworths.

    it should also be noted that it wasnít the diesel that went bang, James.
