Re: Single phase charging

I did some charge testing last night. All values are reported by the car, though I did have my clamp meter inside the charge station to do a sanity check on values. The 3-phase 6A charging looked interesting, I might have to redo that measurement - it looks like the car was actually exporting power ...

Re: Welp, ran out of charge for the first time

yeah, that's normal in that your battery is full. what's happened is the battery is down on capacity. the full scale of the fuel guage (at least on the old nimh firmware) is 30Ah. you likely only have 20Ah of capacity the weakest and strongest cells must be pretty close to each other in both capacit...

That's certainly weird doing a motor calibration may help (it's easy to do and there's no harm in doing it) turn ignition off. lift rear wheel off the ground (a car jack usually does the trick) to get the mc to calibrate, you have to simultaneously hold the throttle at full, have the left brake on a...

Re: Making home EV ready

I'm not sure I understand the issue. The car battery is double insulated just the same as the panels on the roof are. The cars own motor controller output swings from +400v to -400v, so the insulation would be designed to handle that kind of switching. Coincidentally the both grid tie Inverters I us...

Re: Testing a traction pack before using

for things with a thermostat, be aware that switching dc is much harder on the contacts than switching ac. Might be better to use a bar heater that rarely switches, rather than a kettle that switches often

Goodwe make a single phase inverter that goes down to 80vdc input, and also supports export limiting.

all grid tie inverters can handle an unimpeded supply

I used a vintage PVE2500, but there are more modern inverters that will work down to 100v

Re: Fast charging infrastructure - forward-looking overview

The zoe topology has always used the motor inverter and motor windings to act as a charger. There is a version on Europe that has been available for about 5 years that can do 44kw recharge, though you're right, none here in Australia. The zoe motor and inverter are 44kw continuous rated as is, so ye...

Re: Fast charging infrastructure - forward-looking overview

I like the Tasmanian ones in the ocean :D

given the falling cost of powerful onboard chargers, and the poor reliability of stationary DC fast chargers, I suspect by the time there's significant build out, only the "old" cars being made now would use them

might be more accurate to say made to order. last time I bought one it was a couple of weeks. might be more, might be less.

If you're in a hurry, I could sell you the zilla 1k LV that's in my focus?
It's waiting for a new battery anyway, and I've been thinking of swapping it out with a zeva 1k anyway

Re: Making home EV ready

The Zoe power stage is capable to back feeding to the grid (at up to 22kw).
additional communication would be needed between car and evse, and a firmware upgrade for the zoe.

If your byo 20A cable is type 2 compliant, the car will limit itself to the lesser of the cable or the evse current rating automatically.
