    jonescg's eCRX pre-build thread!

    A driveshaft failure in this situation will be annoying, but not catastrophic. I'm not going to be pushing it real hard, at least initially.

    And that was a fairly productive summer! I'll chip away at small stuff between now and the Easter holiday, but I hope to get much of the cabin back together by then... 😬

    Driveshafts are welded! Hope to install these on the weekend and tighten up all the suspension components.

    jonescg's eCRX pre-build thread!

    Minor update - I installed the radiator and dropped another $500 on aircon parts. I also pulled the central locking out since I never used it and put new speakers in the doors. Now all I need is a music playing device...

    How green are lithium batteries EV technology?

    You can also change the search filters for only papers in the last 2 years. It's a rapidly evolving field, and huge gains are being made in very short timeframes. Way faster than academic publishing cycles. You'll find anything older than 4 years can be disregarded!

    How green are lithium batteries EV technology?

    Guys, this is literally the number one research area anyone in the battery / new energy sector has to get very familiar with very quickly. It's easy - go to Google Scholar and search for lifecycle emissions on anything, externalized costs of any process, and even the number of jobs created...

    jonescg's eCRX pre-build thread!

    I took the shafts to a mate who has an enormous lathe, and he was able to bore the inside out of the Leaf shaft to a depth of about 110 mm from where I cut it off. The solid shaft needed to go deeper than that, so we just lopped 60 mm from the ends to be sure it wouldn't bottom out. There looks...

    Driveshafts next. I'm not planning on doing these myself, but I hope to slide the Honda shafts inside the Leaf shafts so I can determine the final length and mark it. Then I can take them to a driveshaft specialist and get them to work their magic. At this stage it's looking like a specialist...

    Copper Tape?

    That's exactly how I did it. And yes, the adhesive is incidental - it smells a bit when you hit the spot welder.

    Copper Tape?

    When used to adhere thin copper (0.07 mm) to nickel (0.15 mm) and then spot welding through the nickel-copper sandwich to the cell below, it increases the current carrying capacity of the connection. But the adhesive is just there to keep things in place.

    Motor is mounted! Some grinding and paint for the welder I ain't left to be done, then I can start to think about the drive shafts.

    Anthropogenic Global Warming is real or not?

    One for our slower chemistry and physics students at the back - a very good explanation as to why, despite representing such a small proportion of the atmosphere, greenhouse gases like CO2 and methane heat the atmosphere:

    Perth is right next to the sea as well. During one of four crazy heatwaves last summer the humidity in the Perth Hills was single digits! Similarly, on the east coast, we have what's known as the 'Sydney Basin'. As the name implies, it's a major confluence of rivers on a floodplain with a...

    We have a lot of housing on the rural fringe. They want the rural lifestyle but can't leave the urban amenity, so they recreate the farm in the suburbs. It's a pretty faithful recreation in that it's got the same vast fields of not much with even fewer resources to service them. The number or...

    Every summer in Australia we have the same argument about forest management, firefighting, global warming and blame. But a couple of points to note are that these fires are epically devastating in the dead of winter. Nobody had full fire management mode switched on because... it was winter...

    jonescg's eCRX pre-build thread!

    Several modifications on the sway bar stays were required, like making it much shorter and re-locating the stay holes, but I got there in the end. It does a pretty tidy job of holding the bar up, and any torsion on the chassis as you round a corner will put vertical loads on the stays, which...

    I bought a used Chevy Volt - and you probably should too!

    Well akshully.... Being an EV guy we actually tried a 2nd hand Volt, and a used 2012 Leaf, because in 2020 these were about the only affordable second hand EVs or at least EVish cars on the market. The Volt was okay, but Australian stealerships don't want to service them anymore and the service...

    jonescg's battery builds (historical reference - image heavy)

    You can see I used expandable foam on the new 12 kWh race bike battery. Not much I might add - just enough to secure the balance wires. But you can get low density potting compounds that aid waterproofing and vibration protection without massively increasing mass. They are generally good at...

    jonescg's eCRX pre-build thread!

    Little more progress on the motor mounts. Lots of cardboard aided design, followed by Sketchup made for an easy shopping list of laser cut 4 mm steel parts. I can weld these up with my stick welder no trouble. Hope to have these welded up by next weekend, and the Leaf motor mounted the weekend...

    38% of cars sold in China are now electric, Sinopec says the ICE is doomed

    Hybrids will have their moment in the sun, but short of deliberate interference from recalcitrant automakers, BEVs will get back to winning the sales charts in a year or two.
