Solar charging

We have a standalone system PV powered system in Melb and a farm 100ks away. The latter has grid power & a standalone system that runs all refrigeration and a HWS heat pump. It has a 5kW inverter/charger & around 2 kW of PV 48V LA bat bank 1000Ahrs. I have 4kW more PV to install. This will charge my...

Melb to Perth by Tesla?

I have ordered an 85S and am already planning my trips. Some years ago I did Melb to ACT and Melb to Adelaide using my Charade & 11kW of charging plant I took with me. The range was 150ks max however I did Keith to Horsham running te 3.6Kw portable gen set & drafting a semitrailer at 110ksph. I am n...

DC Regen from practical and personal experience.

Those plug in prius kits include a 48V to 200V (or whatever it is) converter to supply the traction pack so there is equipment out there. I already have a number of 250VDC to 240V AC transformerless inverters that I can mod for my purposes. D

DC Regen from practical and personal experience.

Ive been agonising over regen myself. I think it really only has value for significant declines which I have to confront in my travels now. My suggestion is an isolated DC-DC for the field and picking off the armature direct via an isolated DC-DC boost converter. In my case the first DC-DC will prob...

Panasonic Home Lithium Storage Battery

I do solar systems for part of my work. My next project which will sell solar to the grid and possibly resell off peak power for more at on peak times cannot proceed unless I go LFPs. They are the answer not only for transport but static solutions as well. DS

EV Run to Adelaide AGM and Festival, 2010

Charging statement is not quite right. Both batteries are in parallel and are both charged & discharged in parallel. I have 46 LFPs & 12 AGM. At the end of a 100k run battery voltages were about 140-144 V so I dont think I was abusing the batteries. For the run from Melbourne to Adelaide I will be s...

recharge points long term view

The Tesla has an optional ($US3000) 70A high power charge cord. Prob uses the VSD circuitry to charge but you need to get a sparky to put it an outlet for you. It would have to go back to the switchboard. We lesser beings should be happy with 20A 3ph/20A or 1 ph 15A. On my next long distance trip Il...

EV Run to Canberra AGM 2009

Just to advise all. I returned to Melb about 7PM tonight, having spent Monday in ACT at the War Memorial. No petrol was used. Longest leg without a charge was from Holbrooke to Wangaratta about 136 ks. Still plenty left but volts dipped below 130V @ 200A battery current. So safe range is about 140ks...

LiFePO4 terminals and straps chemistry

You could prob make your own using Zinc dust, ground up sand & Vaseline. Zn dust ex paint shops. To grind up the sand, lay a bead of sand on your nearest railway line & await the train. Sweep up with kitchen brush & tray. A little railway iron into the mix too I guess.D

LiFePO4 terminals and straps chemistry

Youll have to contaim yourself until I get the goods. There is also silica in the compound. A company called Dulmison makes something too. They have a fluoride compound which is supposed to break down the films.

LiFePO4 terminals and straps chemistry

The TS cells came with 0 instructions. I used SS bolts & var washers. Applied torque intuitively only. No prior prep. I had good contact until the run to B'rat where high currents may have caused problems. With two chargers running (33A charging current-I'd have had a 3rd charger but EV Power bought...

I have ordered a commercial paste from an electrical wholesaler. This has 30% zinc dust which I hope will act as current paths. Ill treat about 10% of my cells and report on findings for different applied torques.

Maybe one day there will be a network of charging stations with 3 phase power, the only way to do fast charging with conventional mains. David

Missing Link for charging. I cannot find anyone willing to let me charge at Seymour. If anyone has friends family or business within 20ks either way willing to help pl let me know. Can do odd jobs while charging for 2 hours. Contacted so far without success-2 caravan parks, RSL, Seymour High School....
