OneWheel Posted March 13, 2016 Share Posted March 13, 2016 Ride the ninebot up to 40% battery. It was pitch black had the headlights on, temperature was about 15 degree celsius , ninebot temp was about 37 degree celsius. Went up the wrong path up a very steep hill (100m long) , had to turn back by going down the same path, the ninebot was beeping as I attempt to go down the hill. Walk the ninebot down to the hill. Continue to ride for about 400m down a slight downhill than up a medium hill. Then ride for about 100m flat surface. Then attempt to go down a medium steep hill, the ninebot started beeping, got off the ninebot onto a flat surface, used the trolley handle to push the ninebot on the flat surface, ninebot continue to beep beep. Decided to swap the battery, then use the trolley handle to push the ninebot across the road on flat surface. On the first mount the ninebot beep once, got off, on the second mount, the ninebot beep once but decided to take my chance and remain riding...no second beep! Ride the rest of the 7km up and down hills with no problem. Is this beep beep sign the ninebot is going to malfunction in the near future? Thanks.

SuperSport Posted March 13, 2016 Share Posted March 13, 2016 I wonder if this and the lights issue are related? Both are connected to motherboard. I haven't heard of this beeping before. Maybe ask Ian at Speedyfeet. He's usually willing to help when he's able. Have you wired anything directly to your board? Extra lights, etc?? Maybe there's extra stress there?

OneWheel Posted March 13, 2016 Author Share Posted March 13, 2016 No extra wiring. I turned on the Lamp On in the OTHER SETTINGS menu, Light Rings now working. The ride was excellent.

OneWheel Posted March 13, 2016 Author Share Posted March 13, 2016 Wonder if going downhill simulate hard braking which french fries the motherboard causing beeps? Does the regeneration have store energy stuck in traffic for short term somewhere? ... since the unit hard NO trouble going up hill, medium downhill was a beeping problem right after a BEEP BEEP steep downhill, even dismounting and using the trolley handle on flat surface was beeping...temperature was only 15 degree celsius! REMEMBER Ninebot have a SCREW DRIVER with you in case need to use it in a emergency. Link to comment Share on other sites More sharing options...
johrhoj Posted March 14, 2016 Share Posted March 14, 2016 My ninebot occasionally beeps as well. I think i understand why. It is beeps when i am going uphill (slightly uphill, but near max speed) and use more than the nominal power of the motor for some time on end. Especially small bumps in the road makes it beep in this condition. The best remedy is to slow down a bit and thus stop overcharging the motor. I never had my ninebot beeping while going down. I am over 100 kg (not much) and therefor uphill demands a lot of extra power. I am going to buy a new EUC with bigger motor, just for this reason. (Prob a Kingsong 18, 1100W) Link to comment Share on other sites More sharing options...
Vik's Posted March 14, 2016 Share Posted March 14, 2016 Another thing worth mentioning is "change lights by knocking"/"knock on the switch". I had to turn this setting off as it was way too sensitive... and gave me a double beep without reason. Link to comment Share on other sites More sharing options...
OneWheel Posted March 14, 2016 Author Share Posted March 14, 2016 I had a feeling the knock/knock may have been trigger by mistake while the lamp was turn off. When the weather is nice will retrace the path exactly to duplicate the beep. Need to know the truth. I will post result either a PASS or FAIL for ninebot.

Paco Gorina Posted March 15, 2016 Share Posted March 15, 2016 I have been doing descents off 300m continuos and have had never a problem with my Ninebot e+. Usually it spends much more energy going up than recoverd going down. Starting with 100% batt, going 300m up in about 6km an returning gives a 50% consumption and a m'inimun 19% of battery.

faipassa Posted March 16, 2016 Share Posted March 16, 2016 Hi, Very interesting graphs which clearly confirm that going down a hill regenerates the battery, despite of the driving speed over 20 km/h. Was only assumption to me so far. Then, what about the period around 20:1 on your graphs? The alt is almost constant, speed is 0 and again the battery looks recovering a bit of health. Did you do a pause on top of the hill ? Link to comment Share on other sites More sharing options...
Paco Gorina Posted March 16, 2016 Share Posted March 16, 2016 I was stopped. Battery seems to always recover something after a good climb. Also interesting I did the same climb much slower and with some stops and although the total battery use is just a bit more the minimum is less. Also at about 13/15 minutes the NB began to tilt back and I had to reduce speed but battery level is flat Link to comment Share on other sites More sharing options...
