My first public fast charge

Toombul first charge small.jpg Please pardon the poor quality of my photos; my phone has a poor camera and is always getting foggy. My Leaf isn't actually green, it's just bathed in green light from the two Tritium 350 kW chargers to its right. It seems that all three of these chargers are new; the...

Re: 4048 Inverter as 3 Phase setup but utility is only single phase

The problem is now that the Utility is single phase and so the Inverter for Phase 2 and 3 would have no input. Somebody know it is possible to run Phase 2 and 3 in off grid mode or I will get error 84?? You won't get fault code 84, at least according to my analysis, as that only happens with the ou...

Re: WTB - EVSE Suit Nissan Leaf

The emergency EVSE ("granny charger") for the Holden Volt was the cheapest option for a while; the part number was GM-23487637 .

Toombul shopping centre (Brisbane) chargers

I'm a public charging noob, so I don't want to mess things up. But it seems to me that the information in both Plugshare and Chargefox are wrong for this site. For example, Plugshare says that there are two CHAdeMO stations, but I saw only one today. It has two ports, but one of them is a 50 kW CCS/...

Re: Battery interconnect sizing

I believe it squeezes out and only fills the gaps to make the joint corrosion resistant. So you don't use too much of it. The conductivity relies on the metal to metal clean surfaces. The Noalox just tries to keep them clean.

how can I test the IGBTs.
A bit difficult to test completely. But seeing the anti-parallel diode is a pretty good test in practice, since 99% of MOSFETs and IGBTs fail either short circuit or open circuit.

Re: PIP-4048MS and PIP-5048MS inverters

can we get the voltage up to 66v for charging ... There are other problems. The main one is that the bus voltage is mostly tied to a multiple of the battery voltage; for the 58.4 V models it was 8:1 (I assume that they use a smaller ratio for the 64 V models). So 66 V would push the bus voltage too...

And competition for the most outrageous, rather than a usable system for actual listening. I guess it's a hobby. A very expensive one, I suspect.
