CHAdeMO charging video - how to plug in

Thu Dec 22, 2011 1:05 pm

Found this video on how to properly plug in the CHAdeMO connector.



Make sure you keep your fingers off the big lever when first plugging in and removing the connector!

No wonder all those handles are bring broken by the newbies. I would have tried every no-no in this video. This design doesn't seem foolproof at all.

I'm pretty sure that the handle that's broken on existing CHAdeMO units is a little red handle on the side, not the big beefy handle pictured here. The handle was redesigned to remove the little red handle that broke easily.

See here for example:

Perhaps someone who has used the Mitsubishi Cypress QC unit can comment on whether it's handle had the red lever or not...

Here's a recent post that indicates the black handle broke in the most recent case at Mitsu Cypress.

Yes, the small handle is no longer on the current models. It is not hard to figure out without instruction, but it does take a couple of false starts to get it right. If anyone wants to try it out or play with it, I will bring one to the next BayLEAFs meeting. Personally, I think this connector could have been simplified, and I am working on a better design without as many moving parts that is still just as safe and even more durable.

Here are some pictures of the QC at Mitsubishi on the day that mwalsh and I charged there.

I had trouble inserting the plug. I think that I was trying to push in and squeeze the black handle simultaneously. As the video shows, you also need to push in to compress the flexible folds at the near end of the handle before you squeeze the black handle. My impression was that it was not intuitive and not easy for those with smaller hands and less strength than me, an average 60-ish male. As you can see, there is no red handle on the QC at Mitsubishi.

Here in Portland, the two QC units with the black buttons have been broken (one was broken twice). The one QC unit with the red handle is still in working condition and hasn't ever been broken.

It must take some skill to break the black handle - the handle looks pretty beefy. Anyone have any idea how people are breaking it?

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...

The thing is definitely not intuitive. I've used one plenty of times, and it still seems awkward each and every time. Just a tiny bit more thought would have been rewarded with a more obvious and idiot-proof design.

Either way, the video was fun... and the sound track ROCKS!

The handle does not break, is the gear inside that gets locked somehow. See the post below:

1- Do not squeeze the black handle with any force at all. If it doesn't move easily, it isn't inserted correctly.
2- When inserting the connector, do not squeeze thee black handle until the connector is fully inserted in the receptacle.
3- Once inserted, gently squeeze the black handle. It should move effortlessly. The back part of the blue handle moves forward towards the receptacle.
Last Sunday I stopped by Fred Meyer for a quick charge. I put the plug in and tried to squeeze the black handle but did not move. Tried a few times to reset the plug but it still did not work. I did not try to force it. I was disappointed that it does not work (I would have driven to downtown to use one of the other two QCs). I tried one more time and while slightly squeezing the handle I lightly pushed the release button. I heard a light click and handle released and I was able to squeeze it. I only charged for about 10 minutes and around noon I came back to charge to 80%. This time the handle worked just fine.

Could it be that people walking by squeeze the handle and cause it to lock? Did pushing the release button really help? If you have problems try the release button, but remember I did not have to use any force.
If you watch the video you can see that the release button moves down and up while the handle is squeezed. So maybe pushing the release button did help unlock the handle :) !
