Re: 3 phase outlet, what is suitable for EV charging?

Thankyou all for your replies. That transformer does connect into the supply cables for the rest of the street, but all of those places were already supplied by the SA grid and transformers. Probably something to do with balancing the phases or what ever. The other white conduit goes to the workshop...

Re: 3 phase outlet, what is suitable for EV charging?

So, that would be the circuit to supply one or more 3 phase EV chargers? I never did get my head around how 3 phase converted to watts, 22kW appears to be the biggest expected demand, would this cabling and circuit breaker be sufficient to supply 2 units at the max expected 22kW output running simul...

Re: HELP PLEASE I think I killed my cells

You can buy a cheap 12v car battery charger with a low output and connect it across 4 cells in series. It will keep cutting out on overload but that doesn't really matter because that will slow the recharging even more. I've rescued cells from as low as 0.4v, a 400Ah 12v pack with a total voltage of...

I can't read anything on the transformer name plate, the markings are washed out, but I took some photos Nameplate.jpg Transformer on pole.jpg The cables into the workshop go through that white plastic pipe and underground to the main fusebox.

Re: e-nv200

With that sort of range even under their "Worst case scenario" in the follow up video, 290km, we could get from Mannum to Adelaide and back on a charge with a load. This might be the next workshop vehicle once the taxi Prius dies.

3 phase outlet, what is suitable for EV charging?

In my workshop I have multiple 5 pin 3 phase outlets marked as 10 amps on the cover. Groups of these a re protected by a 16amp circuit breaker. There is a 3 phase connection box with big cable running from it to a separate RCD marked C83. This circuit powered a monster hydraulic pump that drove a br...

Re: Battery cooling academic paper

Wind chill across pure water can remove a lot of heat because pure water can transfer 3 times the heat energy of air, so only small narrow tubes needed to move the heat away from the cells. Water looses a lot of it's cooling efficiency once it is mixed with anti freeze or corrosion inhibitors. Mixed...

Well the decision to make it a shorter range, lower voltage car was made. Sad, but I'll feel much better knowing that there's nothing rubbing of chaffing against something it shouldn't. It will make for a less powerful car too, with peak current around 200 A and 270 V nominal, it's a mere 55 kW mac...

Re: Bushbus and my gumtree stuff around. Bushbus needs cells

So, you are looking for a min of 200Ah @ 24v nom. of LiFe cells? 3.2 x 8 x 200 = 5120Wh. How many $$ do you have to spend? Freight might be the killer here, but I expect I could get a set up using good second cells up and running at a reasonable cost.

Re: Calb cell pack unhealthy

How many cells and what Ah do you expect to have left over? Not over complicated to build a 24v battery pack and 24v 5kva inverter/chargers with a built in 80 amp MPPT controller are cheap enough and they can be linked together to build the capacity you require. Around 12mths back we built a 10kva s...

What price and range with the new 2020 model? The Kona is just a little out of our price range so we will be sticking with our PHEV Prius for the moment, but I'd love to buy a brand new EV sometime soon.

Re: Starting to research vintage Mazda conversion. Help appreciated.

The regen in my PHEV Prius was rather expensive a few mths back.

Certainly a stealth battery pack install using an otherwise wasted space. Will you need to fit any cells in the back area as well, or will all the cells fit in the side pods?

Re: Starting to research vintage Mazda conversion. Help appreciated.

And the clutch in a conversion is largely to make upshifting, and in particular, downshifting a bit smoother. Understand that part, but if the clutch wouldn't hold the torque of the mighty 1500cc twin carb ICE engine, it sure wouldn't couple up a high torque electric motor. The grip the brass butto...

I had the "high performance" 1500 SS model of this vintage as one of my first cars. Couldn't keep clutches in it if I drove it hard, the gearbox was never a problem though.

Re: Can I use different capacity cells

You will find the 700Ah cells will wander more than the 7 x 100Ah cell group. The 7 x 100Ah cells tend to balance each others strong and weak points out within the parallel pack, the single high capacity cells can't do that because they can not shift any differences in resistance or capacity to the ...
