Bosch Powerpack BMS repair
In this video I repair a Bosch Powerpack battery with faulty BMS. The diode of the 5 V voltage regulator was shorted (which happens often). After this small repair, the battery is perfectly fine again.

Bosch Intuvia: replacing internal battery
Просмотров 55 тыс.3 года назад
In this video I'm replacing the internal battery of a Bosch Intuvia (used on Bosch ebiks: classic, active line and performance line). When the Intuvia has a dead battery, you can only power up the bike with the button on the battery. Luckily this is fixable without buying a new one.
Hello sir, I have the same battery, but there is a problem with it. It broke down, and when I opened it, I found a little water in it. I want to know if I can fix it or not.
If the cells are still good (and don't have any oxidation), it can probably be repaired.
A real joy watching this very instructive video. Very nice materials/tools (tin’suction’ device, board’clamp’ etc.) and taking proper care of your health (‘fume hood’/air suction). Keep up the good work and great posts

very helpful
Vandaag bij de dealer geweest waar ik mijn Gazelle e-bike vandaan heb. Hij heeft geconstateerd dat er waterschade in de accu zit. Is overigens ook te zien, dat er condens zit in het gedeelte van de laadindicator. voorheen laadde hij nog op, maar nu beginnen het 2e en 4e lampje te knipperen. is dit nog te herstellen? of moet ik de accu laten vervangen? Ik kreeg als advies nog om m op de kachel te laten drogen, al gaf hij er wel weinig hoop op, en raadde mij aan om een andere accu te kopen.
Hangt ervan af hoeveel schade er is. Mag je in ieder geval niet te lang mee wachten.
Can you please give me an advice? I'm familiar with motherboard repair. So I have a few BMSs like this. I found traces of liquid damage, but the diode and the power chips are fine. No short circuit on the board, and the 36v rail is ok. The balancer stuff is ok. But when I plug it in, it flickers the 2 and 4 leds which is an error. What could be the problem with the board? Edit: The cells which I connect to test, are good cells, and i have working boards also, so I measured everything and they are the same. I mean I measured it when not connected to power. I'm new these boards, and don't know what volts should be where, like for example on a laptop motherboard, or BMS.
Could have multiple causes. Probably caused due to the current measuring circuit. Needs to be cleared with diagnostics software after repair.
@@wim4245 I will solder the BMS to some good Bosch cell pack and take it to a guy who has the software. I know, I have to be in contract with Bosch to have the software, and that is why the EU manufacturers will go down the drain. I can program any Bafang I want if I buy the tools.
Does anyone know the part number of the diode? I'm gathering this is some Schottky Diode? I have a dead BMS and I'm measuring 0.3v drop and 3k resistance in what I am guessing is the forward bias and a 2v drop and 10k resistance in the reverse. I'm a complete novice but that reverse bias is looking very suspicious to me and I think swapping out the diode is worth a shot, but I don't want to swap it out with a wrong part.
Have you already had the case that for example three of the LEDs are on after pressing the button but charging still doesn‘t work? I measured the 5V and they are okay. Also the charger is working with another battery and the cells are balanced as well. Would be nice to get any help!
Hi thanks a lot , done and work !!!! for me more than 100 euros spared , thanks a lot , if you follow bosch advice you have to replace the dispaly !!
Can't see what you were doing - better close-ups please!
Hi Wim, What a great video. Could you send me a list of the tools you use for the repair?
Any rework station will work
Hi Wim, thanks for the video. My Intuvia powers up. Shows the battery fully charged. I assume that means the bike main battery. Within a minute, it shows message shutting down and does what it says. The same thing happens when I power it on while off the bike. I did try charging on USB. Do you think it may be the internal battery? It is a 2016 machine.
If it works while connected to the bike, it could be the battery.
non si vede nulla, dovresti riprendere dall'altro locale!!!!!!!!!!!!!!!!
Great video 👍Just saved me a lot of €. Thx and greetings from Belgium 🇧🇪
I hate 99.98% of RUclips. These kind of videos give me hope. Just ordered some batteries on AliExpress and will be fixing a bunch of Intuvia's that are no longer working due to depleted batteries. Thank you.
Hi Wim I have a BMS fault on my Bosch power pack 400, how do i find you?

Hi Wim i have a problem with the BMS on my power pack 400, how do i find you? thanks
heb je ook ervaring in de Bosch powertube bms??
Ja
@@wim4245 kan de powertube bms hersteld worden of gereset.
@@rduwe9466 Ligt er aan wat het probleem is
nice video but please some closeups on next videos , looking out for your next videos
Hallo dag Wim , bedankt voor u video, Kan het zijn dat er origineel eerst een andere diode in zat ? omdat ik op de diode van nu geen ss14 of ss16 zie staan, Alvast bedankt
Origineel is het een SS14, maar dat staat er niet op.
Welke diode moet er in ik wil dit zelf ook doen alleen ik weet niet waar ik hem moet bestellen en welke
Dag Wim, batterij geopend, zie veel waterdruppels, lampjes werken niet, maar laad wel op! batterij gemeten en helft geeft 25v en ander helft 1.2v. bitter weinig lijkt me. plaatje lijkt me wel door corrosie aangetast, heb het wel schoongemaakt maar is duidelijk zwart aan de zijde van de lampjes. zijn deze apart te verkrijgen? of alsnog te repareren??
Wim, what do you think about a blown microcontroller? Should I just simply buy a new bms instead?
If the MCU is shorted, a new BMS is the easiest solution. If you have a BMS with water damage, you could swap the MCU. Keep in mind that other components on the 5 V and 3.3 V are probably also blown and in need of replacement.
@@wim4245 thanks for the fast reply, then I'll keep this BMS as a spare and just buy another BMS.
Hi. Great video . I have problem disconecting wires from PCB. Soldering iron at 450 Celsius!!!. What went wrong?
Not enough power or oxidised tip. I can solder them fine with my 130 watt JCB.
Hey man i have a bosch powerpack 400 and i completely drained it now it will only have 1 solid green bar and will not charge at all.
Could be anything from faulty cells to faulty BMS
WHat diode do you need to replace where to get it from?
SS16, from any electronic parts seller
Hier ook een batterypack 500 met led 2 en 4 die knipperen op de accu. Laden kan niet meer. Handleiding zegt dat de accu defect is, meer niet... is hier ook de bms stuk of eerder de cellen? De leds, de printplaat vertonen wel vochtsporen
Waterschade moet hersteld worden en foutcode gereset met diagnosesoftware (op voorwaarde dat er geen schade is aan de cellen).
Shame we don't get close enough, can't really see what you're doing. Thanks anyway!
Hi Wim, Ik heb de schottky diode verwisseld en als ik de bms aansluit op 30V dan lichten alleen de eerste 3 lampjes op, betekent dit dat hij wel werkt of is deze dan ook dood
Aantal LEDs zegt niets over de werking, dat is gewoon de laatst opgeslagen SOC.
I fixed such a malfunction beforehand, now the processor is damaged😢
Hé. Wim. Can you fix de Bosch classic bms?
Depends on what the problem is. I don’t have many parts for them in stock, since they are becoming pretty rare. The older they get, the less interesting to repair (the cells also degrade).
Beste Wim, heb een Bosch accu die geen snelheid meer aangeeft en geen ondersteuning met fietsen. Wat gaat het kosten op dit te repareren? Hoor het graag. Met vriendelijke groet, Hans Leende
Kan niet worden gerepareerd worden
mijn powerpack is ook defect, waar kan men de diode kopen en welk type moet ik hebben? Kan ik mij bord eventueel opsturen voor herstelling? en wat vraag je ervoor?
Hallo Wim. Duidelijke en interessante video. 👍🏻 Weet je wellicht ook of er iemand is die een Bms kan repareren? Liefst in Nederland?
Stuur me een mailtje. Ik heb een herstelbedrijf en heb al duizenden Bosch BMS'en hersteld.
Als ik een stevige berg of heuvel omhoog fiets dan valt vaker de ondersteuning weg, is dit te wijten aan een mindere defecte cel en dat dan door spanningsval het BMS de accu blokkeert (Powepack 400)? Kan het ook aan het BMS zelf liggen ik heb er net een ander ingezet van een andere accu? dank
Dat zou inderdaad kunnen
LEDs 2 and 4 flash. What can be the error?
Could be multiple errors. Mostly about wrong current measurement. Must be reset with diagnostic software after repair.
Hi... should the battery have an output of 42volts standalone when checking with the multimeter? I am getting variable voltage output of between 9 and 10 volts at battery output and 41.0 volts across the opened battery pack. Would the controller send data over battery data wires to BMS to switch and increase battery output to 41.0 volts? Many thanks... I bought gazelle with impulse motor and German battery not working.
This is a Bosch battery, not an Impulse. Most (qualitative) batteries needs communication to activate.
@@wim4245 thankyou...so can I assume the controller is not signaling the BMS to activate the battery full voltage.
Ik heb een 400 Powerpack 2018 voor in het frame en daar zitten op het BMS 2 aansluitingen op die naar de motor (+controller) gaan, kan ik het BMS van de accu in de film voor deze accu gebruiken ik zie nergens die 2 connectoren ..?
Hardware is identiek, ook de connectoren
@@wim4245 Ik heb mij een gebruikte 400 Accu zoals in filmpje gekocht op Marktplaats en daarvan het BMS gebruikt in mijn eigen accu en het werkt! Is wel een enigzins geklooi om de accu case weer goed dicht te krijgen zonder iets te beschadigen. Dank voor de antwoorden en raad!
welke diodes zijn te gebruiken?
SS16
Hi there. Great video. I have the same issue. Which diode did you use, I have only 250v in stock but i feel this is too big. Thanks
SS16 is best
@@wim4245 Thank you! DC Repair Group.
Hi @wim I followed your steps and now the Powerpack turns on and charges. However when I connect it to the bike (2019 ecube reaction hybrid pro 400, purion display, Bosch 250W 75Nm mid-drive) the display turns on, shows the battery status and the riding mode but shuts off in 2 to 10 seconds. If I try to turn it on while paddling I can feel the motor engaging correctly but the bike shuts off regardless after 2 to 10 seconds. I tried reset the battery and tighten/adjust the battery holder with no luck. Any thoughts? Thanks for helping!
Difficult to say without diagnosing the battery. De battery turning off, is probably because the BMS senses something is wrong. Could be imbalance, faulty current reading, temperature out of range… These could be caused by a, actual fault, a faulty connection, but also caused by a faulty component. First step would be connecting to diagnostics computer.
wow even applying silicone for the gasket impressive.. .. i was typing this comment and there was you text haha .. nice attention for detail btw. the moment i saw the gasket i thought after this diy fix i would buy the intuvia screen / rain protector just to make sure..
thanks for the nice vid..Groeten uit Den Haag.
Hallo, where can buy this diode?
It's a regular SS16 Schottky diode
Hoi Wim. Wat is het onderdeel dat je hier vervangen hebt. Is het een specifieke diode en waar kun je die krijgen?
SS16 diode
What is the three pin plug?
CANbus + charge signal
@@wim4245 Do you know some way to start driver without CANbus?
@@jacek7092 You have to send the right CAN signal to activate the battery, it won't work without.
wim, geweldig alleen welke diode, staat nl niets op en dan ook nog waar te verkrijgen ??
SS16
Wish that was my battery being fixed as mine only gives me walk mode
which type of diode i must use ? do you have e part-number or title for diode or any link ?
Best to use SS16
@@wim4245 Super ! Many thanks for the quick reply. I ordered the replacement part. let's see if I can bring the BMS back to life. Greetings from Chemnitz too.
Thanks a lot! On the back of my display, it says 5.0V === 500mA. Would the 502030 3.7V 250mAh be fine?
Those are the specifications of the USB port. The battery is fine.
TK for this good vidéo Where can i buy the Schottky Diode ? What is the references of this diode
Best to use an SS16
