Re: I-MiEV Main battery cell failure

No jokes - it should be easy enough to fit considerably more kWh in that space. 24 kWh is certainly doable with NMC or LiCo cells. I've been putting batteries together which would easily do this, however it wouldn't be cheap. Unfortunately 24 kWh would cost more than the value of the car simply beca...

I'm keen to see what we can do with the battery enclosure - easily fit >25 kWh worth of new cells in there!

This is where he's coming from I think. Perhaps he didn't specify that the inverter needed to be an inverter / charger? Presumably the one with the transformer built in?

Pairing up a battery inverter with a grid tie inverter...

Here's a quirky (and probably dumb) idea suggested by someone on the internet: Take a grid tie inverter and power it with a 2 kW array, for example. Take a 3 kW DC-AC inverter powered by a 10 kWh battery. Parallel the AC outputs of both inverters, protected and switched, of course. Turn on the Batte...

Re: Dreamers Questions. Hillclimb 4wd Racer

Yeah we had a 9 kWh battery on Voltron and it would have put out ~190 kW to the rear wheel. The current 6 kWh pack puts out 175 kW to the wheel. I'm just thinking he might want the extra capacity in order to get to the event sort of thing. The added power of a big pack would certainly help but the w...

Re: generator-motor, you'd be better off leaving a gas engine in there if you take that approach.

Re: Battery Box building

I reckon this will work pretty well with the Leaf modules. However if you can, try and squeeze them in so there's good contact all the way out to the sides of the enclosure. Then it should be able to soak any heat away. The polycarb lining will limit how effective this is, but you will need somethin...

Hey we're all here to help! Definitely choose the motor and inverter first. That's the heart of it all - the electric moor is what makes the EV such a dream to drive/ride. Pick the power you want and make sure the motor spins in the right range for your final reduction. For a car with a 3.5:1 or 4.2...

Re: Dreamers Questions. Hillclimb 4wd Racer

LiFePO4 cells are safer for sure, but they lack the energy density we desire for a road-going EV. I think most LiFePO4 cells are 110 Wh/kg at best. However within LiFePO4 is a range of capabilities, including very high discharge rates (30C) and very low rates (think yellow Thundersky cells etc). LiC...

Re: Dreamers Questions. Hillclimb 4wd Racer

14 laps of Bathurst at 80 km/h. Maybe 4 at full race pace. If you want 100 km range at normal road going pace, then 20-30 kWh would work. This will drop to about 40 km as soon as you put the hammer down because speed kills range. I put lithium cobalt packs together if you're interested - not cheap, ...

Re: Dreamers Questions. Hillclimb 4wd Racer

I'd agree with Richo - power is what you need for short format racing. Lithium cobalt chemistry is perfect for the job as it's got reasonably good specific energy (150-160 Wh/kg) and very high specific power (>6 kW/kg). Either motor can be made to work - the Emrax will just need a bit more thought a...

Re: Dreamers Questions. Feel free to call me an idiot.

Sounds like a fun project. If the purpose is hill climbing, I'd say go full electric rather than a hybrid. Hybrids have been done before, but they are not common - check out Elmofo's Nissan project for example. The Emrax motor is a popular choice but there are a few points to consider; mainly it is ...
