EVSE Upgrade

Wed Apr 24, 2013 5:06 pm

For those of you who waited and haven't got this done already, your procrastination has really paid off!

They now offer adjustable charge current settings - From 6 to 12 amps in one amp increments on L1 and from 6 to 13 amps in one amp increments on L2 . . . . all for only $287!!

Sounds really versatile! Only downside I can think of offhand (comparing it to buying the Clipper level2 charger that's currently on sale for $500) is I'd have, so to speak, "all my eggs in one basket" if my one and only combo L1/L2 charger failed or got damaged or stolen.

Don, Do you have the earlier version of this upgrade?

I've been using the original version of the evseupgrade.com product on my Nissan LEAF for 2 years as my daily plug. It's worked flawlessly, both at home and at 4 different RV parks.

What is the charge acceptance rate for 2012 at 120v?
I thought we can only do 8 amperage. The 2013 in Canada can do 12. Mitsu made improve ment for 2013.

Can I buy a new 2013 evse charger or do evseupgrade to charge faster at level 1?

If it was that simple to have faster charge at level 1, why Mitsu did not include a charge option.

Other threads on this site have theorized that Mitsubishi limited 120V charging to 8A to reduce loads on the wiring. So yes, it is that easy to get faster L1 charging.

Hi Randy,
So I take it you got an adaptor that fits RV park 240 volt recepticles?
Did you get that from the EVSEupgrade folks?

Have any report on charging with your evse-upgraded on 120volts?
Like how long for full charge at 12 amp (vs the stock 8amp limit)?
Theoretically it should charge 1.5 times faster than stock even on120volts.... 14 hours instead of the nominal 22 hours.

Nearly everybody needs an adapter to use the upgraded OEM EVSE - They return it to you with a molded L6-20P twistlock connector installed on it - You mate that to a pigtail with a L6-20S twistlock on one end and then whatever plug you need on the other end to fit whatever you want to plug it into. At a minimum, you'll need their $25 pigtail which has the standard NEMA 5-15P so you can plug it into an ordinary household outlet. Another pigtail for 240 volts would also be advisable. I don't use either at home because I installed two matching L6-20S sockets side by side in my garage - One for 120 and the other for 240. To use it away from home though, I'll need the pigtails

Yes, I've been using the earlier version of their upgrade for about 9 months now. I use mine 99% of the time on 120 volts @ 12.5 amps for everyday charging. I also have a homebuilt Open EVSE which I keep plugged into the 240 outlet for those rare times when I need a faster recharge

Yes, Alex, your figures are about right - It's a roughly 50% faster than when it was an 8 amp unit. Mine recharges at about 5 or 6 miles per hour . . . . 11 or 12 hours for a full recharge if it was nearly empty

The acceptance rate using L1 is about 15 amps, I think. The upgraded EVSE would do 15 amps *if* the cable from the EVSE to the car had heavier wires, but it's only 14 gauge, so they have to limit the current to about 12.5 amps. Your upgraded stock EVSE would make more $$$ sense than a new one because both do 12 amps L1, but the upgraded one also does it on L2

Don gave as good an answer as I could.

I do not have my iMieV yet, but it probably works like the LEAF. The car determines the power draw after communicating with the EVSE.

I bought 3 pigtails when I upgraded, then went to a hardware store and bought the most common heads, a 30 amp TT, a 50 amp RV, and a standard 120 volt style. Most of the time it charges in my garage just the way I got it from EVSEupgrade.com, plugged into a dryer outlet. I carry the other heads with the cable when I go on out of town adventures. Until we get more EV infrastructure built out, RV parks are a great resource. I always call ahead and ask, offer to pay $10, which is a standard dump charge (so they can process the charge), and tell them the max amount of time that I will be there. While charging, I use the facilities like the pool, spa, restaurant, etc. It takes a lot of planning and I don't do it often, but it can be fun. I've only had 1 RV park owner say No to my request.

I'll second Randy on charging at RV parks- can be very useful. However, I'm 0 for 3 on trying to get park owners to consent to a listing on PlugShare, offering their stalls to travelling EV'ers. They're too scared of losing an RV overnighter, and said that it'll usually be okay on a case-by-case basis for those 'in the know', but not if it's their last open slot or a reservation is inbound....

I was pleased with how much faster the car charges on 110v, 13 amps, and everything works great at 220 with my new twist-lock outlet.

I did have to send my EVSE back as it needed a presumably forgotten firmware upgrade and kept faulting. He paid shipping, but it was still a big hassle since it's my only EVSE. It's been flawless since, however. I don't know what kind of converters I'll need apart from a standard 110, and at $40-50 a piece it's a bit steep if I don't know I'll be needing a charge.
