Re: Electric Vehicle Charging Hub in Adelaide

They announced earlier this yr that Mannum is going to get a Tesla charging station some time this yr. Things happen at a rather slow rate out here in the c-o-u-n-t-r-y :lol:

Re: i3 BEV Gen 1: hill climbing energy investment?

That climb up Mt Brown is a killer, mega steep all the way. I doubt there will be a lot left in the battery pack by the time you get to charging point but it should make it if you don't try to set a hill climb record on the way. Looking forward to your feed back one just how much it does use and how...

Re: powerwalls

I installed an off grid 15.4kWh LYP battery pack, 5.6kW of solar and a 5kva inverter at a residence in Crystal Brook South Australia last yr. I had the sparkie wire up the mains into the inverter as a grid back up just in case there was a run of poo solar days. This residence already has a 10kW back...

Re: Stray Capacitance

Would a drain resistor between the aluminium cases and chassis with the chassis connected to the 0v terminal work? Does this sort of idea work with static discharge build-up as well? The reason for asking. I'm guessing it is static build up but quite often our Prius will give a good bite when anyone...

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

I had to Google LTO to find out what it was .... The clue for me was how a 48 V battery was said to be exactly 20 cells, that means 2.4 VPC. The only chemistry I know like that is Lithium Titanate ; it seems it's also known as Lithium Titanate (LTO) (see also Wikipedia's page on Lithium Titanate, L...

Re: 2018 Nissan Leaf!

Off grid is not a problem, back to grid or any sort of grid connection to the off grid system hits the brick wall and at best cancels any grid feed in tariff you might already have .... well that was the story in South Australia anyway.

Re: Inside an iMiEV's LEV50 cell

I haven't destroyed one of the newer cell thankfully, so I haven't actually stripped one out to check the plate material. The things that lead me to believing they had changed the plate material to all aluminium is both the positive and negative terminals are now aluminium, not a copper negative and...

Re: Inside an iMiEV's LEV50 cell

What chemistry do they use and how much electrolyte was left in the cell before you dissected it? It looks like they use the copper as one electrode and aluminium as the other indicating that was the metal used for each type of plate, is this correct? Winston did use this method but now seem to have...

Hi Simon, I've had success with the 15 cell arrangement charging via a PWM controller using nom. 12v panels (18v Vmp) in series. The 24v units come in 5000va (4kW) models and they don't seem to have current rated issues so I can't see the 48v model having issues. The days of needing high voltage bat...

Re: PIP-4048MS inverter

Yeh, buyer beware. I noticed on fleabay quite a bit of cable was advertised as 4mm2 but then when you read the description it actually said 2.x mm2 or others provided no detail at all. The "cheapish" cable I bought is roughly 4mm2 - aluminium though. Hence my plan to run individual cables to each s...

Re: PIP-4048MS inverter

3 x 4kW inverters linked in 3 phase would produce how many kW 3 phase? Energy is always conserved. Power is just energy per time, so power is also always conserved. So 3 4 kW inverters produces 12 kW. That can be as 3 single phase loads at 230V and 17.4 A each, or three phase to phase loads of 400 ...
