Re: 200V AC Japanese EVSE on 230V AC NZ Power system: Any probs?

Fri Mar 29, 2019 7:42 am

The only issue I could see is it maybe could fry the metal oxide varisistor.
When I converted my evse from boring US 120v power to use 240v US power I had to remove the MOV surge protector and install my own.
The control transformer may get hot running the slightly higher NZ voltage.
But if everyone is doing it is probably fine.
Do you know what the 230v power there actually reads on a multi meter?

More than likely they are using 300v MOVs on 200 and 230v systems.

I did not have to replace my control transformer because in the US we use 120/240v center tapped transformers. So all I did was run transformer primary wires from one of the lines to ground. So the transformer still gets 120v power to it.
This is not really allowed but oh well.

Japan uses 100 V and 200V. The us uses 120V and 240V. Some European countries use 220V and a 200V EVSE should work fine. A 100v EVSE will not; Most Leaf;s are calibrated for 100V charging. Thus the time for L1 charging is off. It is merely cosmetic since who looks at the charging time?

The generation 2 leaf EVSE doesn't need the 230v transformer rectifier unit, but when you cut the cable to change the Japanese plug for a NZ caravan plug there are two additional yellow wires. These need to be joined with a 10kOhm thermistor between them, which can be bought from Jaycar. I used a strip connector because soldering might cause issues with the thermistor. The thermistor is a temperature sensor which reduces the amperage if the plug heats up.
