Bryan Wells Posted January 15, 2018 Share Posted January 15, 2018 I checked my tesla's charger temp after it had been charging for 3 hours and it was 167F, does that seem excessively hot? what are your guy's temperatures? I cant even hold my charger for more than 5 seconds Link to comment Share on other sites More sharing options...

I cant even hold my charger for more than 5 seconds I don't know, but you gave me an idea. Thanks! I have one of those harbor freight temperature sensors that I never even thought to point at either of my chargers. Dang it, I just charged the S1 this morning, and it is still at about 85% charge so until I ride it down to about 50%, won't be charging again for a day or so. I always touch the chargers to see how hot they get, they get very warm, but I think I could hold them for as long as I wanted. Then again, my batteries are 320wh, less than a third of a Tesla. How did you check the temperature of the charger? I think separate threads for the most popular models of the most popular brands would be an interesting addition to the forum. Gotway Tesla, Kingsong 16S, Gotway MSuper, Kingsong 18S, and so forth. Link to comment Share on other sites More sharing options...

I use a gun just like that and I hunt for the hottest part of the charger, seems like the center of the sticker side Link to comment Share on other sites More sharing options...

LanghamP Posted January 22, 2018 Share Posted January 22, 2018 My MSV3 gets too hot to handle as well, and I've also lost a charger when it broke while charging. Do the 84 volt wheels require more out of a charger than say, the 60 volt Kingsongs or the 50 volt Segways? Link to comment Share on other sites More sharing options...

The voltage should play a minor role for power dissipation - with the switched mode power supplies this just increases the switching losses. Main part should come from the supplied current.

And yes, they can both get pretty hot, so that you will not touch them, while i dont have exact numbers. Link to comment Share on other sites More sharing options...
LanghamP Posted January 22, 2018 Share Posted January 22, 2018 What about fast chargers? Presumably they use more wattage. Charging an MVS 1600 from 30% or so takes an ungodly long time with the standard charger. When I have two wheels charging at the same time the room gets significantly hotter.

Most (maybe all) have active cooling using a fan and heatsink to exhaust the increased heat from the unit. Link to comment Share on other sites More sharing options...
Smoother Posted January 23, 2018 Share Posted January 23, 2018 My ks 14c (340Wh) charger gets warm, but my KS16s (840Wh) get quite hot. Both 67.2v, same output values but different brands. I'll try to swap them over to see if the cooler one get hotter when charging the bigger battery. Link to comment Share on other sites More sharing options...

There are some smaller ones Floating around which are known to get extremly hot..... Link to comment Share on other sites More sharing options...

No, they are exactly the same size except the newer, hotter one is a few mm taller, when standing flat on the pads.. The cooler one reads 66.8V on a voltmeter, and the hot one 66.7A so that's about the same. I'd take photos but I don't have a reliable photo service right now. The last one I used, turned out to be a free trial. All my recent photo posts are now blank. And the old one I used to use won't send me a password reset email, so I can't use them either.

The Man of Mead Posted January 27, 2018 Share Posted January 27, 2018 Only had my Tesla for around two weeks. Have only charged it around 3 Times so far, but the first thing I noticed was the temperature the charger gets to while charging. Worryingly hot.
