gholm's Morris J2 Van- 1966

Reversing polarity of battery isn't a biggie. Any protesting elements could always be hardwired back to reverse if they just don't like it. That said, it is just a head space. I'll probably leave it alone since : - It works as is. - I've already hardwired in many LEDs lights - (minor) Diodes on all ...

hey all, no real point updating with anything except to say I've been stuck a bit troubleshooting the 12v system. Having driven a few happy laps of the block as pure EV, I thought it wise to get the 12v system working as intended, those blinkers, brake lights etc, all things that keep a man out of t...

Exciting news! Today was the day that my Morris J2 van moved for the first time using none other than electric power!!!

The 12v latching relay idea is similar to what I'm planning to put in my van although I don't have a seperate Accessories switch, only ON and START. Good idea for the unused dash lights too. I have been looking online and found some good ideas at www.the12v.com, where there's a few options built up ...

In regards to protecting the Kostov from road dirt/water/dust, I don't know. I'll see how it goes. The fan outlets are toward the front of the car, so I'm imagining that may keep most smaller crap away. Otherwise I'll fashion something suitably ugly to match the rest of the underside! What do people...

I haven't weighed it yet post-conversion, but pre-conversion it was 800kg on front axle and 480kg on rear. That B-Series motor with gearbox is probably 160kg, plus another 25-30kg of various other stuff from around the vehicle. The Kostov is about 90kg. Will be interesting to see how it feels suspen...

Definitely makes sense.
Sometimes you just need to pay the man to do his thing.
DIY doesn't always cut it, especially with family/work/life expectations.

Awesome conversion man, love that vehicle... a real driver's car.
Nice work.

I'd be interested to find out more about how it works and is wired up. I have the Kostov R20, same wire and weird circuit diag on the spec sheet. If a thermal overload does trip a circuit, what voltage gets switched? By the look of it, coming from A2, it'd be the full pack voltage (in my case 144v)....

Nothing yet but there'll be some big bars of square nylon (nitrile?) plastic across the top of the cells, and screwed in to the box horizontals.
I wanted to get all the wiring down and tidied before I can position them.

Haha, yeah later later.
Will be covering that whole box with 5mm marine ply, then carpet, once my engineer has OK'd the installation.

Time for a bit of an update.

Here's some preliminary renders of my initial designs. Belt probably won't take the full power, so a fatter one will be needed. The green parts move linearly as shown by the arrows.

OK, enough people have commented on Direct Drive, so I've reverted my plan back to very original, and ditch the gearbox and clutch altogether. This will cause the motor to draw a lot of amps at low speed and I've had quite a few warnings on doing this with a Curtis, so I've ordered a Zeva to use ins...

Yes, the reconfiguration of the drive train has always been at the back of my head. I'm inclined to continue as planned to mount the Kostov onto the gearbox, keeping the clutch and gear box, and I understand that plan is fraught with future disaster when I next need a gearbox or clutch overhaul/repl...

I used Blender on a daily basis, and I cannot recommend it enough. I should say that although it's reasonably easy enough to create something sub -millimeter accurate in 3d, its output is not designed for CAD/CAM machines. If you're like me and you just want to "lego" your designs, play around with ...

Yes very nice 3D work! I'm not an engineer but on some of the designs there doesn't look like there's much room between the batteries and the frame.
