Rotator Posted August 12, 2015 Share Posted August 12, 2015 Since it is easy to find cheap converters from 12v to ...whatever until 80v or more, and two amps, we can charge the ninebot in our car.The only trouble that I can see, is how to find a connector to put into the charge port of our ninebot.Anyone knows which kind of connector is, or where can we buy it?

Daan Posted August 12, 2015 Share Posted August 12, 2015 Not sure, but I did find this: http://store.inventist.com/store/p/46-Solowheel-Car-Charger.aspxThis is for the solowheel classic, I wonder if it would work for the ninebot too? Link to comment Share on other sites More sharing options...
SirGeraint Posted August 12, 2015 Share Posted August 12, 2015 SpeedyFeet charges his Ninebot One in a car in one of his videos. I thought he just used an inverter. Link to comment Share on other sites More sharing options...
Gimlet Posted August 12, 2015 Share Posted August 12, 2015 Much simpler to simply use a converter to bring it to 220v and then use a normal charger.This is what I shall be using when I get my Tesla with a 90Kwh battery to draw on. Link to comment Share on other sites More sharing options...
SirGeraint Posted August 12, 2015 Share Posted August 12, 2015 That's what an inverter does. In the U.S. it brings the 12V DC from the car to 120V AC and provides plug-ins for AC equipment. Link to comment Share on other sites More sharing options...
Gimlet Posted August 12, 2015 Share Posted August 12, 2015 Converter inverter same thing in layman's language. 120v for US, 220v for UK.I'm a great believer in the "keep it simple stupid" method. Even though I am quite aware that there is a huge loss in efficiency with the double conversion rather than a direct conversion from 12v to 67v. You would still need to control the input so that charging stops once the battery is full. Link to comment Share on other sites More sharing options...

You would still need to control the input so that charging stops once the battery is full.I would be wrong, but I believe that our charger is not more than a AC-DC voltage converter, not a real charger. Nothing to stop when battery is full, but a led light to let you know when there are current going into the ninebot or not. The BMS into the battery would do all the related tasks about charging, stopping the charge, and balancing cells.Not sure about this, Only what I believe. But if true, I prefer not to carry the original power supply since I do not know when will be necesary at the car. Only personal preference. I prefer to have two, one at car and one at home. And a DC-DC circuit for the car will be a lot cheaper than a new original power supply and a DC-AC converter.Anyway, I also believe in your "keep it simple stupid" method. Have a lot of sense.

Gimlet Posted August 13, 2015 Share Posted August 13, 2015 A lot of it is cost. An inverter can be bought very cheaply and even if you choose to get a second euc charger they are very cheap as well.As 12v to 67v converters aren't in general use as far as I know you would either have to rig one up yourself or get one made which is likely to be far more expensive.

Jason McNeil Posted August 13, 2015 Share Posted August 13, 2015 That's a bit high for this charger, it an be bought directly from Ninebot for about $25. Link to comment Share on other sites More sharing options...

esaj Posted August 13, 2015 Share Posted August 13, 2015 But where to find the ninebot one port plug?AFAIK, it's a Lemo-plug, but don't know the size: http://www.lemo.com/enHi, isn't it that one: 4 pin connector ?At least that looks like the right kind, but there are varying sizes of Lemo's, so probably would need to double-check the dimensions. And of course polarity from the old plug Link to comment Share on other sites More sharing options...

And of course polarity from the old plug Great!!!It appears to be the 1P series.I will check the catalog with the dimensions and types, and I will put the reference to public knowledge, for DIY or just to substitute the original in case of a breaking it.Thank you very much.

Gil Posted August 13, 2015 Share Posted August 13, 2015 You are right ESAJ. Googling '4 pin medical connector' shows many providers (I was a little bit amazed that Ninebot has a Swiss provider). Link to comment Share on other sites More sharing options...

Jag_Rip Posted August 13, 2015 Share Posted August 13, 2015 I had a 2011 VW Passat Stationwagon and it came with a standard wall plug on the rear seat as well as another one in the trunk to charge laptops or power electric coolingboxes.I am not familiar with electricity stuff, would this not charge the EUC or very slow?http://www.amazon.com/gp/product/B003Q54V88/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B003Q54V88 Link to comment Share on other sites More sharing options...
Gimlet Posted August 13, 2015 Share Posted August 13, 2015 It says it's a 3.1amp output so more than ample for the normal euc chargers which are mostly 2amp but not for the faster 5amp chargers. Link to comment Share on other sites More sharing options...
Jag_Rip Posted August 13, 2015 Share Posted August 13, 2015 So for simplicity sake get one of those and use the charger that came with the bot and be good, right? Unless you really want to have a more sophisticated DIY solution. Link to comment Share on other sites More sharing options...

The ninebot charger will need 120w or so.I have tried a 100w power inverter and did not work at all.You will need 150w at least. May be 200w in order to have an extra safety margin.

Rotator Posted August 13, 2015 Author Share Posted August 13, 2015 There are lots of different models that will not fit.Please, let me check the right model number.The right plug part number is PAG.M0.4GL.ACnnc, where nn is cable maximum diameter in milimeters (one decimal digit), and c is the color.nn: 20, 39, 52 or 65 (6.5mm max)If you want a bend relief, then add Z at the end of the part number.

525rider Posted August 13, 2015 Share Posted August 13, 2015 From my experience the cheap invertors don't work very well with chargers, you need a more expensive one with true sine wave. My ebike 48V 12A LIFEPO4 battery charger drawsabout 300W. Link to comment Share on other sites More sharing options...

My ebike 48V 12A LIFEPO4 battery charger drawsabout 300W.I believe that our charger is a switched power supply, so must have a full rectifier bridge and capacitors to get DC voltage at the first stage. I do not see any problem with square wave (like in cheap power inverters) In that input stage.Anyway, a true sine wave will be better, since all the electronics quality will be improved too in this more expensive converters, and not only the waveform.

525rider Posted August 17, 2015 Share Posted August 17, 2015 I'd like to see an "expert's" opinion on this. I also think that the charger that comes with the unicycle is in fact just a power supply and the BMS regulates the charge. If so this converter should work:http://www.ebay.com/itm/331591959890?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT Link to comment Share on other sites More sharing options...
