Add DC quick charger?

Mon Mar 11, 2013 12:46 pm

So I didn't get the chademo option. There were zero chademo chargers in my area until about 1 week ago and I intended to only use the i for around town.

Now that the chademo is online, i'm thinking it might be kind of cool. Can the dealer add this or is it factory install only?

As a factory-installed item, CHAdeMO costs around $750. Adding it afterwards is around $1300 just in parts (according to other threads on this site). In short, it's not cost-effective.

In the wiring diagrams that I've studied, there is no contactor in line with the CHAdeMO cable connections, unless the battery cables from the onboard charger and CHAdeMO both connect to the same point and then go through the same contactor that is part of the pack assembly. That would be sweet. I do see a "Quick Charging Relay ", connector #105, but it's a low amperage apparently 12V device. (HELM manual section 80A)

The Nissan CHAdeMO cable is $9xx over their parts counter, which someone who was ready to buy could use as a negotiating point, to match price on our $1280 cable (though it's a couple of feet longer, which has gotta be $2 more in copper).

Could somebody who has CHAdeMO check the following with a DVM? While under J1772 charge, do the two big pins show pack voltage? I thought I checked them on a friends car when it wasn't plugged in and got no voltage. May have a chance to check a friend's car again this week..

I have contacted both the dealer and Mitsubishi Motors North America about adding the DC quick charger. Both have told me that it cannot be added by the dealer. However, it looks to me that the only parts you would need would be the release latch that goes next to the driver's seat, the DC cable from the battery to the DC port, and the female DC connector. The door to the DC quick charge port can be opened because the cable is presently run to the back of the car for those of us that do not have the DC quick charge option. If you open the back hatch you will see a plastic cover on the right side. Remove the cover with the two finger latches and you will see the cable. Pull on the cable and the DC quick charge port will unlatch. It looks like this cable can be rerouted to the driver's seat, or you could install the latch right there. I have been wanting to install the option myself, but I would need the part numbers to order. I have gotten part numbers from the dealer's parts department, but they seem reluctant to give me the numbers. I have ordered some parts from ricartparts.com. They have reasonable prices.

That's right RobertC, and my dealer happily sold me the release latch and assorted hardware at a reasonable price across the parts counter, complete with printouts of the relevant diagrams. I haven't installed it yet, though :roll: ...

Wait a minute, you guys actually HAVE the parts?

Is it really just plug and play or do you also need software?

I don't think there will be a voltage. The owner's manual mentions that if you try to charge from both the L3 and the L1/L2, the L3 will take priority. I'm thinking there is a relay in there and possibly some logic as well. Voltage at the terminals would present a safety risk, I couldn't imagine that would be allowed to happen. I can check for you but I don't think there will be any voltage even while charging with the J1772.

Those may be the physical parts, but probably aren't everything you'd need

Something regulates the whole quick charge process and I'm betting it's not a part of the base model car - If it were as simple as buying and bolting on the parts you list, your dealer would likely be very happy to do that . . . . but I think that's probably only half of the story

I guess when you install those parts and try connecting it to a ChaDeMo charger, we'll probably learn the REST of the story

jray3,
I see that Quick Charging Relay in the manual. When I get a chance I'll check to see if it's there (the wife loves it when I start taking the car apart). The dealer mechanics really have no experience with 330V DC, so I'm guessing that Mitsubishi probably doesn't feel comfortable having them do the installation of the DC quick charge cable.

Agreed, it shouldn't energize exposed pins and yes there's a bunch of com wires, but I'm not seeing a separate DCQC/L3/CHAdeMO contactor in the wiring schematics, and of course L3 would take over in a conflict, as it'll be putting 50kw into the same bus that normally receives 3.3 kW max on L2, and the L2 charger is controlled by the CAN signals. The onboard charger will throttle back based on voltage and amperage readings from the pack, but the car's only recourse if a DCQC charger does not obey commands would be to open the charging contactor. I haven't found a description yet of if and when that would happen.
As far as I can tell, there's no switch that tells the car when a charging door is open or shut. Also, the official Mitsu Technical Information Manual for the car only lists three contactors. (Page GR00001400-54D-8) There's a main contactor at Batt POS and NEG, and then another that's referred to several times as the charging contactor. It is on the positive side of the battery, bypassing the positive main contactor. This is a very similar design to my homebuilt EV.
Another promising test would be to check for 330V between CHAdeMO negative and any HV positive terminal (like the DC/DC input or onboard charger output) when the car is in 'ready' mode.
