Re: Prelude conversion project - some questions

On second thoughts, a new Honda prelude radiator would make more sense. It comes with it's own fans and all the bolt holes match up. Instead of a two-part radiator, I might just put a full-sized automatic transmission radiator in front of the main radiator. If I'm not mistaken, the air conditioning ...

Re: Proposed "New Energy Industry" CRC for Australia!

Cost to set up will be more in Australia (although that's changed for the better now that construction firms are scratching around for work) but the operations side of things is no different. Electricity might cost 2-3 times as much as China, but energy is only part of the equation. Anyway, we know ...

Re: Proposed "New Energy Industry" CRC for Australia!

Unlike you, I'm far more optimistic about the proposal. Battery manufacture in Australia should cost exactly the same as anywhere in Asia. The entire process is done by machines and they cost the same no matter where you build them. We could just as easily set up a gigafactory here in Australia to e...

Re: Prelude conversion project - some questions

Water pumps have been ordered - I got three of the Davies Craig 15 litre per minute pumps. I suspect one of these pumps will be powerful enough for the inverter + motor + DC/DC converter. But not sure sure if they're up to the task of the charger + battery cooling loop. They sell a 23 litre per minu...

Re: List of cars with electric power steering pumps

I bought an Astra pump from a "TS" model. It's the one with the "smooth" bottom on it. I think the other kind has heatsink fins on it. https://dl.dropboxusercontent.com/u/301235/EV%20Project/300zx/IMG_20130608_153520.jpg The connection for this one is two high power leads and a 3-pin connector.

Re: Prelude conversion project - some questions

So I bought one of these: Strom-linie Astro water heater.jpg It's got a really basic contactor which is modulated by a bimetallic thermostat. I'm assuming the contactor is rated to the task. Still chasing AC compressors, but it looks like there are some good 5-6 kW, 380 V DC powered options around.

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

If they cost twice as much as an LFP battery of equivalent capacity, you might as well buy a LFP battery of twice the size and get 4 x the cycle life (of an LFP battery half the size).

Re: Large ebike packs - how are they?

18650 cells are usually NCM, but also LiCo. They have great energy density, but typically rather low power - that is, they sag heavily under load.
All cells will benefit from a life spent at 20'C - so the closer you can keep them to 20'C the better.
