As long as the inverter has two MPPT inputs you can make that split array arrangement work.

Re: Tesla using LFP in China

Patti McBain has been driving her converted Focus for over 100,000 km and it's still putting out a useable range. If that's not an endorsement for the longevity of LFP (even if the energy density isn't great) I don't know what is. The new Ioniq having a slower fast charge (50 kW instead of 70 kw, a...

Re: Tesla using LFP in China

It will only be cheaper because the battery is lower capacity. The $/kWh of LFP is actually higher than any nickel or cobalt based cathode. Should make them a bit less prone to fire at least, but the BMS will need to be updated. I also read that they would be sourcing prismatic LFP from CATL. So the...

Re: Prelude conversion project - some questions

The welded contactor inside the battery is indeed a GX14 contactor. The drive contactor up the front used to be a Kilovac 200, but since replaced it with a GV240 contactor with auxiliary contacts for alerting me to a stuck conductor. And it's stuck again. So my solution is to abandon the master cont...

Re: Prelude conversion project - some questions

Any chance the charger or DC-DC converter for 12v may be causing the problem? It's a possibility, but more likely I think it's a timing thing within the inverter. Besides, these are already powered constantly by the traction pack since the master contactor is stuck on. The main +12 V supply to the ...

Re: Prelude conversion project - some questions

Re: Aussie electric vehicle sales triple in 2019

Agree with most of that Dave. For as long as an equivalent ICE is $20k cheaper, EV sales will struggle. $20k buys a lot of fuel. It's also not helping that the legacy automakers are using existing ICE chassis to electrify their fleet because the shopper's immediate instinct is to compare it to the e...

Re: Aftermarket iMiEV battery upgrade project

I was planning on using 0.8 mm thick FR4. I used to buy big sheets of it from Regal-Beloit in Welshpool, but I think they stopped selling it. Now you have to go through a wholesaler to buy it. I like FR4 because it's tough, strong and is like kryptonite to electricity. As for the buslinks, I don't w...

Good question... I was planning on getting some 2 mm copper busbars made up with enough cross-section for about 40 mm2. Unfortunately, one crappy little M4 screw hole is pretty ordinary contact, so I plan on putting a kink in the buslink just to the side of the screw hole to ensure some decent surfa...

Re: Aftermarket iMiEV battery upgrade project

Yeah I fully expect any metal cased battery to be live to the case now. Rather disturbing the spec sheets mention nothing about this.
I think the FR4 will work OK. Not ideal, but what can you do.

Re: Aftermarket iMiEV battery upgrade project

I wonder if that's part of the reason these cells are high energy density and low cost - they forgot to include some key features :o

Yes, a lightglobe will light up between (-) and the case.

Re: Aftermarket iMiEV battery upgrade project

It's live alright - 0.01 ohms. Turned out it's just continuous between the case and battery (+).
I can get sheets of 0.8 mm thick FR4 between the cells and use 5 mm thick PE on the outer edges. Not ideal regardless.

Re: Aftermarket iMiEV battery upgrade project

Just checked and sure enough, the case of the cells is live :|

Sometimes it's consistent with the (+), sometimes it's continuous with the (-). So basically these cells will need to be packed out entirely with polyethylene so they can't touch each other, or the clamps.

Bugger.

Re: Aftermarket iMiEV battery upgrade project

One option is to use the existing clamping frames, but it makes securing the cells relative to each other a bit harder. Otherwise I'm looking at 3 mm plate aluminium and RHS with threaded rods. And lots of insulation between them.

Re: Aftermarket iMiEV battery upgrade project

new cell layout.jpg This looks to be the least worst termination arrangement for the 60 Ah prismatic cells. It allows for the modules to be terminated at the forward end, meaning a lot less copper than otherwise. Fly-wired to each cell top will make the BMS happy. The BMS should sit on top with a m...
