It seems that in the past month or so an annoying issue crept up with chademo. Namely at random our cars (we have four) can't charge on chademo stations. The session starts, but the amps aren't ramped to max, but stop somewhere in between (where is random, sometimes 40A, sometimes 60A also 75A etc). Then after a minute or so they drop to 0 and it looks like the charging was stopped. Then about 30s later it starts again and it repeats. Usually after N cycles it just stops altogether and a station error is reported on dash. Using other stations has no effect (one customer tried 5). Other cars on same station charge fine. Different adapter on the same car works fine. Then you charge on AC a full charge and lo and behold chademo works again. Or it may just be random... In any case we've not found a direct correlation to stuff except that maybe it's tied to battery warmth. A customer yesterday charged on AC, drove 140km and put to DC and it worked (while failing tons of times on 31.12). we've heard from other Tesla owners in Estonia that they too experience it. No clue if it's temperature related or not, but it may be... Have others elsewhere seen this?
