Re: CHAdeMO charging video - how to plug in

I've never used one of these before since my car does not have QC. But my first thought upon seeing pictures of them is "why is it so huge?" I mean when I look at Tesla's charge port, there is an enormous difference in size.

When I saw Phil's at the Nissan meeting in Mt View, that was my first thought too.

Watching the video, I can see that it is really badly designed. It just invites the user to operate it incorrectly.

I believe the intention was to make it similar to a gas pump. Hey, you do not squeeze the handle until you put the nozzle in the tank, you lock it in so you do not have squeeze while dispensing gas, you release the handle before pulling out of the tank ... and so on. We had over 100 years to learn those steps, ... well in Oregon they are still learning :D . No wonder the Portland QC connectors get damaged :lol: .

The pull handle operades a cam to pull it in because of the resistance of the large contact resistance. It is actually very well built and designed, the cable is also shielded and very high quality.

I would be seriously upset if I were a QC station owner that had to shell out thousands of bucks every month because the handle broke...
It's not the handle that is getting broken. There is a small catch on the bottom of the connector where it plugs into the car and those have been breaking off because of a design issue. Until the new connectors are UL approved, we're stuck with these versions that can break.

FYI, the ones in Japan pretty much all have the red lever release mechanism and apparently don't have the same issues.

The one I have is indeed UL listed. I do not see how it will easily break even if you don't follow the instructions. It seems overbuilt actually, but I agree that it's a bad design. Apparently the Sumitomo unit is better.

The last step plugging in is to raise the lever.

So, one might assume that the first step in un-plugging is to lower the lever.

But, apparently one needs to press the button FIRST (and hold it down?) and only THEN lower the lever.

Is that the problem?

The lever will lower by itself. The video shows that you push the release button one for the lever to lower and push it again to pull the plug out. I do not recall having to push the button twice. You push the release button hold it down, the lever lowers as you allow the moving part of the plug to come out than the whole plug comes out.

The only time you touch the lever is at plugin when you squeeze it after the main plug is fully seated against the Leaf receptacle.

Yes, the Lever drops by itself once you press the button (providing the red LED is off), and only once the lever is all the way down will it let you pull it out from the port.

If there is any side or excessive downward tension the lever doesn't always pop down by itself though, sometimes it needs you to at least lift a little on the rubber handle part. It's also possible to "help" the lever a bit with a finger to drop down.

Obviously, we all need more opportunities to practice this ;) . Maybe in 2012, I will get my chance!
