Twizy : Symptomes of a failing charger
Hello, And an extra hello to Twizy Specialists. I'm running into what's believed to be a common Twizy issue concerning the onboard charger Since a big week: during charge, after a few minutes (and for sure if I come back to the car while it's ending charge) the SERV light is on, along with the exclamation point battery icon. Upon departure, the SERV is off, but comes back after a few seconds before going away after 3/4km of driving. From what I read, it's the forthcoming signs of a failing battery charger (hopefully, warranty ends in 3 weeks). Though, most of the people who had this usually noticed a missing fan noise, which I believe I still hear. This does not seem linked to the pretty impressive accident I had a few weeks ago (only plastics involved at first sight, gotta plan the budget for repairs until police enquiry+insurance kick in) So, unless I'm totally nuts, I've ever only seen flatline pwr_curr rates (then decreasing approaching topping off). Simply, I wanted to share with you odd power curves from a charger giving it's last breath: https://www.dropbox.com/s/nmbavtx0r2bku4p/twizy_charge_pblm.png [ Arrived early at work nearly (expected) depleted battery (9%), from 8:40 to 9:17: steady 2400 +/- 50 W, then it drops to 1040W at 9:30, before slowly coming back to 1700W at 9:44 then 1550W since... ] Though I've had the SERV on the last charges, since this morninh, a Stats? command shows Charging, Topping Off, even though the time I walk to the office it didn't get to 11% of SoC, and the ETA, at 8:44 seemed consistent at 199 minutes (now 10:31: ETA Full: 105 minutes, SoC 60%)... odd. "Voilà" That's about it... Gotta call the garage now :-/ Hugs and all! JaXX./.

Hi Julien, thanks for sharing, that sure looks like the charger issue, dropping and moving charge power has been reported before as a pre-failure sign. Be aware the "fix" provided by Renault will mean you get a charger that works a little bit slower, i.e. they restrict charge power to ~2000W instead of the 2.300W max with gen 1. But charge times are normally only extended by a few minutes. Regards, Michael Am 30.05.2014 10:52, schrieb Julien (JaXX) Banchet:

Hi Michael, Didn't have time to get the Garage on the line, so I don't know what thay're gonna tell me. That said, I'm not against a few minutes if it avoids stressing the charger too much. Can't wait to update the OVMS :) Thanks, JaXX./. Le 30/05/2014 16:40, Michael Balzer a écrit :
