zeva kindly dropped another of his incredible widgets for spoofing the TC charger. He programmed it to deliver 20 A DC and Vmax of 401 V before dropping it in my letterbox. It's powered by the Charge Enable 12 V supply on the EVMS3, but doesn't talk to the rest of the CAN bus in the car... because ...

Yeah, our budget is pretty firm. $15k max, and must be good for at least 90 km. The last 10 km of which is all uphill.
They wouldn't go any lower than $12k, so they will need to find a customer with shorter range needs.

Just confirms that Richo was up at midnight on the 16th of June

She canna go ne further!

Another weekend, another flurry of activity on the Prelude. After re-installing the main battery pack, I lowered the last two modules in the rear with the help of antiscab and later that night, wired it all up. It's only temporary at this stage, I mainly want to get things working before I start bol...

I can try and offer $5k, and get a $10k battery from Nissan. Or just save our money and find something better.

Aaaand it can't drive me to work on a single charge. We got to the base of the hill and had 10 km left on the GOM. The hill would hammer it pretty hard, so we topped up using the trickle charger for 40 mins. Ended up getting home with 6 km left on the GOM at speeds around 50 km/h. So it's not going ...

I have recently placed a deposit on an ex-fleet Leaf which was on sale here in Perth for $15,000. With 31,000 km on the clock, it was clear the battery was degraded. However after paying Nissan to do the diagnostic test they realised it would be a major failure in the eyes of the ACCC, so they are ...

On plus side you'll brighten everyone's day

Do remember to point them away from whatever you're doing. The seared retina effect gets rather tiresome before too long.

Goodwe make a single phase inverter that goes down to 80vdc input, and also supports export limiting. I've been looking for a cheap second hand one to implement an on grid battery If you wanted to play silly buggers, you could get yourself a 2.5 kW grid tie inverter, a 7 kW solar array and a 60 kWh...

I've done that with my petrol powered motorcycle, so don't feel alone in that sense

Spartan! Compared to the Prelude's engine bay there's so much vacant space!

Yeah the dumber the better - fan heaters, bar heaters, kettles, etc. I like to keep an eye on individual cell voltages when doing a discharge test - any cells which drop markedly lower than the rest are laggards and will need to be watched carefully. Hot spots are always worth keeping an eye on. If ...

Oh good. Cause I was thinking about doing the same

I use a grid tie inverter for capacity testing

Assuming your grid tie inverter can handle an unimpeded 144 V DC supply?

You can run most resistive AC loads on DC, and universal motors are happy on DC too, they just spin slower. So set up a power board and start plugging AC loads in until you get to your desired currents.

Yeah that would get you to the nearest corner store in Perth...

Also in this instance the team required two points of isolation - a contactor on both terminals - and some means of interrupting the circuit should the BMS warn of a cell out of spec. The negative contactor served this purpose as well. It's an awfully large switch for the ~10 amps it's supposed to b...

Terry - I think the Kona is either 96 or 98 cells in series - when fully charged it hits 400-407 V DC.

Another productive weekend, and probably only another day's work to have it rolling again. I connected all the BMS wiring, added some silica gel packages and seal the lids. Once the lids were on I could put the new top brace across the three modules. I bought a MAPP torch and some aluminium brazing ...

Nah, my electric bike was certainly competitive.

Hi all, Unfortunately our incumbent website limits what goes where, and how prominent an article is, meaning really important stuff sometimes gets lost in the ether. One particular resource are the EV Fact sheets which Bryce and Chris Nash have been compiling - these are really well done and rich in...

Paging @zeva

Nice one. Sounds a bit noisy, but then I realised, it's a Moke. That's actually quiet
