Popular Post RagingGrandpa Posted January 18, 2021 Popular Post Share Posted January 18, 2021 Hundreds of boards have failed. The consequences of a board failure, compared to a battery fire, are insignificant. "I saw sparks and smoke!" is the only common thread... (but one stops on its own; the other totals your house). Please let's make every effort to not intermix these two different types of failure. 5 Quote Link to comment Share on other sites More sharing options...

We can clearly see which manufacturer needs to improve the most, nice to see a clear summary in which this stands out. 3 hours ago, RagingGrandpa said: The consequences of a board failure, compared to a battery fire, are insignificant. Both types are pretty bad. I'd like to avoid a battery fire as much as a burnt control board, or any other type of control board failure while I'm on the wheel! And I'm not talking about extreme testing like Marty's Overheat Hill runs, just regular use. A board failure (even without burning) leading to a cutoff while I'm riding at 50 km/h is far from insignificant. I could argue that board failures could lead to serious injury (on me and others as well), versus property damage in case of battery fire. At worst in either case you could end up buying the farm. It would be nice to have a more complete breakdown of failures, organized by failure type, yes. But this is a good start.

On Gotway/Begode wheels: Burnt motherboard can lead to shorting the battery packs. Gotway packs don't have BMS on their output for maximum throughput. A short can lead to a battery fire. Motherboard fire can start a fire of the packs themselves, because of their physical proximity. At least for Begode wheels, the recent addition of a fuse should mitigate the very significant risk of fire by shortening the pack on MOSFET failure.

Fuses are a very good idea and a requirement IMHO in case the BMS doesn't have a quick and effective short protection (which some have) The risk while charging seem fairly low, maybe thanks to the combination of reasonably well calibrated chargers and top-balancing BMS, making it the safer part of the whole process apparently. 1 Quote Link to comment Share on other sites More sharing options...
RagingGrandpa Posted May 27, 2021 Share Posted May 27, 2021 (edited) 19 hours ago, supercurio said: On Gotway/Begode wheels: Burnt motherboard can lead to shorting the battery packs. Motherboard fire can start a fire of the packs themselves, because of their physical proximity. I don't think any of the actual fires fit that description. All we have is anecdotal evidence of burned up controllers which didn't cause pack fires. It would have to be a 'fire while riding'; the handful of those that we've seen have been wheels with electrical modifications. Perhaps the only plausible example was the EUC that burned in a shipping container... if it became powered on in a box, overloaded because of the jammed tire, and exceptionally well insulated in its sealed foam and cardboard box. 15 hours ago, supercurio said: The risk while charging seem fairly low No! An important circumstance to consider is: Cell becomes internally shorted due to internal defects, or over-discharge. Damaged cell now conducts current from the remaining cells in series (during use) and in parallel (all the time), and dissipates heat because of this current flow. Damaged cell or neighboring cells either become depleted (0V), or reach runaway temperature. Recharging the damaged cell provides a practically unlimited source of energy to generate more heat, and so heating will continue as long as the charger is supplying current. Runaway temperature will be reached if the charger remains connected long enough. #1-3 are not preventable: there is nothing to stop the pack from being used with a damaged cell present. Fuses will not help because the current flow is still within the normal operating range. If #1 is the 'internal defect' problem, it could surface any time the cell is being used- it could be charging, or discharging. #4 is partially covered by the EUC BMS disabling the charging input if any cell is under-voltage. But this mechanism can fail if the BMS is damaged, especially by water and corrosion. The risk of an indoor fire is highest while charging. The risk is especially noteworthy for: Brand-new cells and packs Packs that were submerged in water (even if it occurred days or weeks in the past) Packs that show irregular charging behavior (e.g.: won't charge past 90%) Damage to people and property can be minimized by charging in a safer environment, such as outdoors, or inside a metal cabinet.

Popular Post GoGeorgeGo Posted May 28, 2021 Popular Post Share Posted May 28, 2021 (edited) The only fire my friend group has experienced was with a nikola+. Its was on a ride but not while riding, the wheel was leaned up against a wall as my friend was smoking a cigarette. It started hissing and smoking so he moved it away from the wall. A couple loud pops (the capacitors blowing we think) a lot of smoke and a ton of damage, definitely a small fire. Luckily the batteries did not go though so the wheel was kinda sorta salvageable. Cost him 800$ to get it repaired (even though it was warrantied by ewheels) and he still does not trust the wheel anymore to this day. (This happened back in Novemberish) Not a battery fire but still a fire, and a very traumatized rider who has essentially quit the hobby due to this incident. (Not to mention he was called a liar and shamed and even had his posts deleted about the incident and the way ewheels handled his repair so he really has a bad taste for the entire community and hobby now) He no longer rides for pleasure and wants to sell his machine, but is afraid to sell someone a faulty machine so he is stuck between a rock and a hard place.

Unfortunately it was much more than the board, the case was warped from the heat, the gaskets where torched, the wiring was damaged, the tire bubbled, the headlight and speakers where torched. It was really totalled imo but they salvaged what they could and rebuilt his machine. Thats the reason his warranty repair costs where so high, they didnt cover the case the tire the headlight the speakers plus the shipping. Hence his displeasure with the way his repair was handled, a faulty machine cost him 800$ to repair, and ontop of that he was called a liar when he thought the repair was done improperly (the headlight he recieved was much dimmer than the original which made him completely distrust the totality of the repair.)

Cost him 800$ to get it repaired (even though it was warrantied by ewheels) and he still does not trust the wheel anymore to this day. (This happened back in Novemberish) Not a battery fire but still a fire, and a very traumatized rider who has essentially quit the hobby due to this incident. (Not to mention he was called a liar and shamed and even had his posts deleted about the incident and the way ewheels handled his repair so he really has a bad taste for the entire community and hobby now) He no longer rides for pleasure and wants to sell his machine, but is afraid to sell someone a faulty machine so he is stuck between a rock and a hard place. Do you know any other details? Like mileage, year..etc. The board looks old...like a 1st generation, but the battery size looks to be 21700, so I assume this is early 2nd gen Nik+? if that's the case, might want to check if these are Panasonic or LG 21700 as there was a recall last year for the Panasonic cells. The board has been revised since last year and the beeper location also changed. The new board and fan arrangement looks very similar to the RS now. Temperature alarm has also been increased to 79-80 Celsius vs the 65 before and the heatsink is exposed now as well. Photo below is the new board from Nov last year. 1 Quote Link to comment Share on other sites More sharing options...

Yes he had the recalled cells but he had already got the packs swapped long before the incident. It was a fairly early nikola, he had around 1500-2000 miles on it. All the more reason he was so shaken up by the incident. It was a wheel he trusted and had put decent mileage on, no reason really for it to go off like that.

Rawnei Posted September 24, 2021 Share Posted September 24, 2021 Seems like not a lot of people want to look at this objectively and just want to discredit brands. Knowledge is power and knowing causes behind these incidents would be helpful for everyone riding an EUC and worth a lot more than a few simple laughs. It would be interesting to know what is causing these spontaneous fires, logically it has to be a short happening but why? Is it bad soldering, water, battery instability? Has any of these incidents any post-incident investigation and conclusion? Someone much knowledgable then me on this forum could probably chime in with a couple of probable causes other than "it's Gotway". 1 Quote Link to comment Share on other sites More sharing options...
