Electronic Splitter for Throttle Outpu

If the controller accepts 0-5v (Hall-effect compatible input), then you can just use two op-amps wired as voltage followers/buffers with the single throttle as the input. You may even get away with just connecting the single box to both controllers, though you could run in to issues with voltage ref...

BYD China first 30, 186 Mile Range

With the Chery entry level car being discontinued in Australia due to stability control requirements, I doubt we'll be seeing anything from BYD here any time soon.

Awesome stuff, and dirt cheap by the sounds of it. I have a background in aviation (LAME) so I'd be pretty comfortable putting something like this together myself. Be sure to share your progress with it as you continue. I'm keen to see what it becomes.

G2 Prius Plug in Purchased....

I'm interested to hear what you find out. I'm down in Wollongong myself and have no qualms about poking around a big battery pack. I'd love to get a close look at this system anyway, as it's something I'd like to replicate at some point for a Prius drivetrain transplant (I'm thinking PHEV MR2). If y...

I am absolutely in love with this idea. The box-tube centre spine for the battery is brilliant. I wonder if extruded sections exist in a similar size. It would likely be more rigid than the pressed box and bolt-on top. The batteries would have to be slid in on a sort of sled from one end or the othe...

Some people need a bigger car than the 208 or the Mini as well. Hard to beat a 5-door Golf at 3.2L/100km though, even with the cost premium of diesel over petrol.

New source of used first-gen Prius cells?

I just read this article on Hack-a-day about the Ford Fusion hybrid battery. Apparently it uses NIHM "D"-size cells. I wonder if these could be used to refresh a first-gen Prius pack. They should certainly be up to the task as far as capabilities go, and the Fusion is much more recent, so they shoul...

Charging electric car batteries with "portable"

I've heard of some car manufacturers (Nissan in Japan I think) building mobile charging stations to support an EV that's been stranded. They're powered by diesel generators though. To do a portable battery version of it, the size of the portable battery will depend on how much charge you want to del...

New production EVs and PHEV

I'm happy to see these cars coming to Australia, but I worry that without some sort of incentive to help with the price, they will fail horribly here.

Prius Pricing

The NHW-10s looked good for a while, because they can be had so cheaply, because the hybrid batteries were all failing after 10 years, and now at 14-16 years they are definitely all failing. Don't forget the common MG2 stator burn-out problem. There's an NHW-10 for sale in Canberra at the moment fo...

Thanks Bigmouse, for letting us know you're sucessfully using a clutch with a solid centre. I've "opted" for a solid disk, but it hasn't even gone in a car yet. That's for my BMW conversion. That parts are in hand, but that car is still driving as an ICE. The clutch in the 300ZX conversion is a 6-p...

Weber and Coulomb's MX-5

I've opted for a springless hub on my conversion as the springs are not needed. The inertia of the rotor should be less than a crankshaft and connecting rods in an engine, so the torque due to acceleration (deceleration) should not be excessive. Magnetically, an induction motor will never create mor...

Lots of old electrical and EV stuff up for grabs

I see quite a bit there that I could put to use (contactors, heatsinks, desktop multimeter)! Shame it's all out in WA. I'm sure local folks will snag up that stuff, and I'll give them a chance before I approach them with the hassle of shipping.

Antiscab's NWH10 Prius plugin Lithium conversion

Have to found any resources that talk about PHEV conversions in this model? I assume you've looked in to it before starting. How are you keeping the rest of the hybrid system happy with the new battery? Do you have plans to trick it in to having an EV mode?

Subsidies and other EV incentives

I agree that some sort of incentive is needed, but I worry about tactics I've seen in many Australian businesses being repeated here. There needs to be incentive for the entities selling the car to keep the price down. Currently there is none. For example, the Honda CR-Z in Australia costs double wh...

Good info. If the CA cells are the same, then I can definitely see that I wouldn't want to mount them even a little bit upside down. Time to redesign the battery mounting... again.

Hey everyone. I've been curious about this as I'm currently planning on mounting the batteries in the 300zx on their sides. Everything I've seen and read about these batteries is that it shouldn't matter which orientation they're mounted in as they're simply pouch cells inside the plastic enclosures...
