This is a good example of the problems with feature bloat and frequent useless software 'updates' that out-date previous hardware or are with previous versions e.g. microsloft and apple

It sounds to me that they have added another safety test in the EVSE, in addition to checking for ground faults and isolation, to check the resistance of the main contactors on the vehicle. If Mitsubishi didn't update their software to recognize this contactor test protocol, then it won't respond as expected by the Chademo station, and the station won't send the charge.

e.g. Apple won't let some apps run thru my wireless home router because it has upgraded their ios to only accept a newer wi-fi version that uses WPA2 security. WPA has been working fine, never a security threat. This might be useful for a big company but not for home use--there is no threat at home of someone stealing wi-fi when you use a passkey and MAC address filtering.

Interesting issue, hope it ain't so. I'm a heavy CHAdeMO user, and have never had a charging fault ascribed to the car. Just today an EVGO DCFC went offline after a successful handshake due to "over current fault", costing me an extra 30 minute delay (as I had already gone inside for breakfast). Turns out this had been happening for at least 24 hrs (to LEAFS) without EVGO taking the station offline to await repair.
The other EVGO DCFC on that site worked fine.

I recently noticed that EVRUS is a relatively new player around here with CHAdeMO charging stations by hotels on major routes, so I applied for a charging card with them.

Guess what: my card application was rejected and they refunded my PayPal $25!

Reason: "Because the i-MiEV was discontinued, its software has not been upgraded to be compatible with our EV Express charging stations."

I called them asking for a more detailed explanation, and they promised to have someone from their tech department call me. Evidently they had an i-MiEV user who was unable to use their stations and asked for his money back. They couldn't tell me what vintage that i-MiEV was. Perhaps this is a problem with 2016 i-MiEVs... or perhaps with all BUT the 2016? "Contact test" problem described here?:

Anyone with a 2016 i-MiEV having trouble using CHAdeMO?

Goofy. I haven't had a problem with my 2012, with at least four different models of CHAdeMO chargers .

Edit: Ooh, I found this statement on the EVrus web site:

"The EV Express 25 kW is equipped with a CHADeMo connector, which is common for Nissan Leaf, Kia EV Soul, Mitsubishi i-MiEV, Toyota RAV4 EV and also compatible with Tesla Model S (with a CHADeMo adapter)"
