I'm pretty sure now the charger is faulty, I would just like to repair it instead of waiting another month to get a new one. Quote Link to comment Share on other sites More sharing options...

Sorry for the late reply. I didn’t get any notifications. This is the 10a charger it was bought at a group buy so I’m not sure where they got it. It’s up for sale if anyone is interested.

What can I measure or do to make Shure it's either the motherboard or charger. I read that an eWheels customer had exactly the same thing happen... a burned motherboard, plugged in charger, charger died as a direct result. That rider got another charger from eWheels on warranty because, well, it's not supposed to happen like that. I suggest getting in touch with your retailer and make it a warranty claim. Good luck! 1 Quote Link to comment Share on other sites More sharing options...
DoctorP537 Posted April 16, 2023 Share Posted April 16, 2023 So I just got my S22 and right out of the box it would not turn on.Talked to the dealer and they said Kingsong said to plug it in for two days. They think the batteries got below minimums. It has been two days and nothing. The charger goes red for about three seconds and then green then back to red then green again and stays that way. I don't think it is charging it at all. 2 Quote Link to comment Share on other sites More sharing options...

The green light comes on briefly when the charger light is red but goes out when the charger light goes green. Can tell if it is in transport mode because the app won’t connect even when the charger is plugged in. I don’t know how to test the charger to see if it is working correctly.

chanman Posted May 24, 2023 Share Posted May 24, 2023 (edited) When I replaced the motherboard I also found the old charger did not work, I'm not sure why but I think there is some sort of motherboard/charging versioning compatibility. EWheels sent me a new charger for no cost and it works fine, although the charging behavior is a little different.

level9 Posted May 24, 2023 Share Posted May 24, 2023 Unfortunately plugging a bad motherboard into the S22 charger fries the charger. Happened to me.. According to Jason @ at ewheels: Yeah, we've seen several instances of this: after controller blows, & the charger is plugged in, it blows the charger as well, not very smart design...

chanman Posted May 24, 2023 Share Posted May 24, 2023 I don't doubt it, but my board wasn't fried, just was replacing it, and neither was the charger, but it just refused to charge the new board. Quote Link to comment Share on other sites More sharing options...

I have the latest firmware (motherboard+BMS) and the same charger also worked with the older firmware. Do you happen to know the revision # of the motherboard?

Finn Bjerke Posted November 12, 2023 Share Posted November 12, 2023 I was forced to use Inmotion v13 charger on my KS s22 - works fine. The plastic coating the wires leading OUT from the kingsong charger selfdestructs it seems. The insulation on the electrical wires had hardened and embrittled. Making nail marks on that cable is too easy..... Quote Link to comment Share on other sites More sharing options...
LightScience Posted April 23 Share Posted April 23 I have had a breakthrough! Situation is s22 pro, nothing wrong with it, new charger won't charge it. So, I took my multimeter and tested the pins that should have power. Well, I have a loz meter which pulls a little bit more current to test. When I tested the pins, the charger fan started spinning for a second. In other words, the charger tried to charge. So, I plugged the charger into the s22 and on the other charge port, very carefully probed the same two pins, because I know the ports are connected. The charger started charging the wheel!! Another way to do this is to use a resistor or something DC that will draw a little current, but not blow up. I am going to make plugs who's only job it is, is to pull a tiny amount of current. That way, if someone has a charger that won't initiate, but otherwise works, they can get charging. Also, I am going to sole the problem as to why this is happening. I suspect it is something on the charger that is out of spec or miss set. Maybe the trim pot for standby voltage. This charger doesn't just sit plugged in with 126 volts on the line. No, it has only a few volts sitting, to test for the presence of a wheel. It appears that that resting voltage is slightly too low to pull enough current to initiate charging. 1 Quote Link to comment Share on other sites More sharing options...

This charger is known to have bad calibration and can be tuned easily. Quote Link to comment Share on other sites More sharing options...
