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 . But it seems that these aren't available any more, except from this site (price is presumably in US$, and would probably cost a lot to ship). Edit: discussed in this topic...

Re: Leaf for sale with new battery, Qld (sold)

The leaf is home now, paid for, insured, toll activated (transponder coming), and nearly registration transferred (I didn't realise I needed my wife's drivers license to transfer into two names). It's had its first fast charge (by me); I stopped at Jaycar Strathpine for some solar bits, and Toombul ...

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...

They do have the solar charging bug mentioned earlier in this thread (reported power appears to be twice as much lower until you turn PV off and back on). They also do not accept AC input when in parallel mode (the AC input sign just flashes with no error code). When in single mode, the same AC inp...

Ah. More than a "few" voice coils. And lots of fans to cool them.

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.

Not sure I understand this. How does the inverter get to such a high negative battery value? The power has to come from the other output. I've just realised that fault code 60 (error 60) only comes up when in battery mode. When charging from utility, you have to be in line mode (shows "BYPASS" on t...
