1. The European / UK "included" EVSE is L2 (220/240v) not L1 (120v).

2. After this mod to the USA "included" L1 EVSE, it becomes a "universal voltage" (L1/L2) EVSE.

3. This L1/L2 EVSE would still "offer" 12 amps Max to the car, I believe.

4. It is likely that there is more to this "mod" than just replacing a component and the "waterproof" pigtail.

5. Getting the mod and adapters done RIGHT is certainly worth something!

6. Wattage:
120v x 12a = 1440 watts (standard L1 EVSE)
240v x 12 amps = 2880 watts (L1/L2 EVSE)
220v x 15a = 3300 watts (3.3 kW "nominal" EVSE description)
240 x 16 amps = 3840 watts (3.84 kW, a 16-amp L2 EVSE)

7. Useful Pigtails:
a. for 120v socket.
b. for 240v 4-pin (modern) dryer socket.
c. for RV "30-amp" (120v) socket
d. for RV "50-amp" (240v) socket
e. Others

f. Dual 120v plugs for opposite phases. :)

Right, I found that I have both of the two 120 phases in the dual-duplex sockets right near my "old-style" (1978) dryer plug. One duplex socket is on Line1, the other duplex socket is on Line2. Very convenient. Sometimes all the sockets in (most of) one room are all on the same phase.

When I install new "utility" sockets (240v and 120v) in the garage, I will try to do the same thing there.

Don't bother ordering from Nissan, it won't be too long until the stolen ones end up on eBay.

A accessory with this feature is being considered with a safety interlock. Gary is correct on his comments, this unit was completely de-potted which was very labor intensive even for someone with years of experience, after doing this by hand in the most careful manner some parts were damaged and replaced. There were several modifications to the board. The cable end will not be extended on wall side to keep everything as close to compliance. There may also be an option for extending the J connector for those interested. Considerable time and effort went into these modifications, testing was also performed to exceed the voltages as the unit will fail if used on 240,3 even with a universal supply. Any other loads on the charge location in general like a motor, or voltage pitch would also cause a failure without the additional mods. In the testing phase of the original unit it was found to not meet the actual SAE spec.

drees wrote:Definitely interested as well. This will make charging on the go a lot easier, and the Nissan 120V L1 EVSE is very compact.

Combine this with a quick220 adapter and a couple heavy duty extension cords and you can charge at 75% normal L2 charge rate just about anywhere.

Bonus points if Phil can build a quick220 type adapter for less than what they charge ($160 for a 15A quick220)...

If I understand your questions the answer is yes.

Thanks for reminding me to pick up a pad lock for the one I have!

No idea if it is actually in stock however.

We could also look for Volt's EVSE (GM Part 20981776).

Ouch. That's not much cheaper than the AV unit is. More portable though.

On this conversion, pricing hasn't been determined yet from what I heard. But I'd be willing to pay $100 for it, $150 if it includes the common adapters mentioned previously. Not too much more than that though...
