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

Re: Testing a traction pack before using

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

I've been looking for a cheap second hand one to implement an on grid battery

Re: Testing a traction pack before using

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

Not sure what you mean here... reliability on new units today is significantly better than units from 5 years ago.

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

Re: WTB Perth ZEVA MC600SP Motor Controller

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.

Re: Kona EV Real World Range Experience

So the most probable variable that could explain this vast difference (correct me if I'm wrong) is temperature. On the Portland trip, it was 10-12°C all the way and both ways, the temperature in the last 2 days was 24-26°C both ways. Even though I did not use any climate control on either trip, cou...

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.

It'll charge slow but otherwise be fine. If there's too many other things on the same circuit the worst that will happen is you trip a breaker or blow a fuse in your meter box

Any chance of air conditioning your garage? For the distances you propose. Maybe a conversion ev would be better.
