Can I use an Imported Japanese Charger?
- The components in some Japanese EVSE chargers are only rated at 200 volts (For the Japanese domestic market) and NZ’s voltage is 2o% higher than that during peaks. This will burn out some components, and make others exceed their current rating. Please inspect the rating label to determine the design voltage.
- While a NZ domestic outlet is rated at 10 Amps, often there can be more than one plug on a circuit. This can cause the circuit to overload or trip. Worksafe guidelines state that plug-in chargers must be limited to 8A or 1.8kW, unless they have additional thermal protection.
Here is an example of what can happen when a modified Japanese import EVSE is plugged into a domestic 10 Amp socket:
JuicePoint is aware that many plug-in chargers available in New Zealand do not comply with Worksafe guidelines. If your house or Electric Vehicle catches fire, will your insurance cover the damage? Is it worth the risk?
Some Motor Vehicle Traders are modifying the Japanese charger by fitting a New Zealand plug on it, not understanding the rules and regulations. It is also unlikely they are qualified to rewire the plug.
The Imported Motor Vehicle Industry Association (VIA) is aware of this issue and is letting its members know about the rules. However they have received a complaint. You can find an article about this on AutoTalk.
Example of an Acceptable Charger
Below is a photo of the plug in charger for a 2014 Mitsubishi Outlander PHEV. Note that it is rated for 240V and only 8A, therefore it is acceptable to use in New Zealand.
