Re: Prelude conversion project - some questions

I'll have to get a number on this tomorrow, but about 21 kW I think. It takes about 8 kW to maintain 60 km/h, and 14 kW to do 80 km/h.

Re: Prelude conversion project - some questions

I should add - the wobble board effect has been reduced somewhat, but it's definitely still there. I need to mount a gopro under the car and go for a drive to see what's happening. Hopefully the new coilovers will fix a lot of that.

Re: Prelude conversion project - some questions

Drive report - After a few short trips not far from home over the weekend, I decided to drive to work today. I packed the OpenEVSE just in case I needed a 3 phase socket at some point. There was no regen going down the hill. So presumably the controller was set to engage regen below a particular vol...

Re: Prelude conversion project - some questions

Well in the case of the drive contactor, I might swap it out for one of these: https://www.gigavac.com/sites/default/files/catalog/spec_sheet/gv200.pdf The auxiliary contacts are good for indicating it's on (or stuck). I didn't wire up the auxiliary contacts on the master contactor, mainly because I...

Re: Prelude conversion project - some questions

One option might be to abandon the master contactor all together? Since the rear modules are in the middle of the battery, it's easy enough to install an isolator back there. Then I can enjoy having all components at the front of the car being powered all the time, but at least no nuisances with con...

Re: Prelude conversion project - some questions

The charger was replaced with a CAN-controlled one, but frustratingly, the charger ran on a 500 kbps rate, while all other BMS stuff was on 250 kbps. The only remedy for this was to re-program all 8 BMS modules, the current sensor, EVMS and the screen. Thankfully Ian came around to my house to help ...

Re: Storing energy

Screw pumps are low flow, high pressure (head) systems which would be a good fit for sending water a long way uphill. We used one back in Emu Vale to pump about 60 m of head. I use this calculator - https://www.engineeringtoolbox.com/hydropower-d_1359.html Put in the head and the flow and calculate ...

Re: Grounding shielding around motor cable

Check for continuity between the shield and the motor chassis. If there is none, that's good - it means you can connect the shielding cable to the same shield as your BMS communications. You want to minimise any potential ground loops, so have all shields meet at the same point if possible.

Re: Storing energy

I have wanted to do a similar thing in the opposite direction - run an efficient heat pump for cooling water/glycol and circulating this through the home aircon system. If you went as far as making ice you can exploit the high latent heat of fusion to cool things down. Since water has the highest sp...

Might want to do a good balance charge of both packs then. It's a amazing how much energy can be denied when you have an unbalanced pack (and a functioning BMS, lest you have a fire).

Well when all 640 of the first crop of Leafs suffer battery failures and nobody can be arsed stumping up $10k to replace it, there will be 640 Leaf motors for EV conversions available for cheap. The strange thing is, how much is the battery for the conversion going to cost?, how much work is involv...

Re: tractor conversion

What kind of work will it be doing? Will it be doing any serious cultivation or mainly towing things? Because the motor need not be too amazing. A re-wound industrial AC motor would certainly fit the cheap requirements, but it might need some kind of cooling added. 4 pole is ideal for most applicati...

Re: AGM for home storage?

Lead batteries have been the mainstay for off-grid and stationary energy for a long long time - as long as the solar charge controller is set up to charge lead properly they are a solid choice. Not exactly cheaper though - particularly since you aren't able to access a fair bit of the energy stored ...

Re: 9 Nissan Leafs for auction at Pickles: 8 NSW, 1 ACT

Yeah, our budget is pretty firm. $15k max, and must be good for at least 90 km. The last 10 km of which is all uphill.
They wouldn't go any lower than $12k, so they will need to find a customer with shorter range needs.
