Can the Bosch BMS be saved? | Tips for testing (English version) 

I‘ve watched the original video and saved his other videos for later. Now, it’s gone private. What a bummer. Was it because of patent rights?

Can you make a video about the classic line Bosch? I made a mistake connecting the balance cable first before connecting the power and a small 3 point component burnt out and I cannot find out what it is.

sehr nützliche informationen, seit langem habe ich eine defekte bms mit großem restaurierungswunsch, vielleicht hilft mir dieses video weiter

⚡👍⚡

I have a 500 powerpack wich BMS is broken ( I test the diode out of service). Is it possible to have these full BMS in spare parts for bosch or another buyer. Thanks

How to have output without original ebike connector?

I have 3 boards for Bosch can I send them to you to see if you can fix them

What is the three pin plug?

My Bosch Powerpack 400 turned the system off while I was riding. It would restart and last about 15 seconds. Now it will will not charge and I read zero volts on the battery connector. When I plug it to the charger I see led #1 on continually and nothing else. The same condition after several hours on the charger. I tried to reset it by holding the button for 10 seconds and nothing has changed. If I just try to turn on the battery then led #1 lights briefly then goes out. It doesn’t seem completely dead but won’t charge either. ?? Thoughts?

Hallo, habe bei ebay einen defekten Akku gekauft. Es gab Hoffnung, die 18650-Zellen zu ersetzen, aber die Platine stellte sich als fehlerhaft heraus. Ich habe dieses zerstörte Element durch ein Loch ersetzt, das Sie im Video zeigen, weil es auch zerstört wurde. Danach fing das Board wieder an, die Akkuladung anzuzeigen und lädt den Akku sogar regelmäßig auf, aber wenn ich es in das Fahrrad einbaue, passiert nichts. Der Computer lässt sich nicht einschalten. Kennen Sie den Grund? Vielleicht müssen Sie noch das Element ersetzen, das Sie als erstes im Video zeigen?

Do you have a system to test the battery is working without a bike to test if you repair the bms you still are not sure it will work on the bike right? or is there a system to overide the canbus handshake to use the battery or the bike without the canbus data?

Können Sie meine Platine reparieren?

Bonjour Led 2 et 4 ? Merci

I have a bosch 500 power pack for my E bike, And I get the 1 + 3 + 5 flashing lights, the temperature sensor is busted, how does one repair such a thing?

Hei Battery Doctors, I have Bosch Athlet Ultimate 32V vacuum cleaner. When charged is plugged non leds flashing its like dead, but on battery flashing one led. What can be? Temperature sensor? Battery fully charged. Thank you

Hi, do you have any experience with BMS with 5 leds flashing. cca 3s on 5s off Thanks

Hi can you tell us how to charge this bms with normal charger ....thanks.

I need a replacement BMS Any luck finding a source

Hallo, Hen BMS Platin wie in Ihrem Video gezeigt. Es sieht neu aus, keine verbrannten ICs. Aber mit 5 Volt zwischen den beiden Kondensatoren schalten sich die LEDs nicht ein. Die Shotky-Diode ist gut... Was könnte es sein? Ich verwende ein 5 Volt Netzteil mit Amperemeter, es fließt kein Strom beim Anschließen der 5 Volt zwischen den Kondensatoren.

Si potrebbe vedere il video in italiano. Per sapere sul bms bosch.

can you tell me where i can get the blue cap next to the diod

Super Infos, vielen Dank! Kann man ein BMS eigentlich komplett irgendwoher beziehen, z.B. weil irreparabel?

Very instructive, thank you. For a few BMS, when awaking the BMS as explained, 4 LED turn ON and not the last one. Is the BMS OK ?

Where can I get the diode from is there a specific one?

They can be swapped with another BMS: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jRkLBh6oztg.html

o una scheda che non si accende 500w ci possiamo mettere in contatto

Einen LIPO.....ungesichert an irgendwas anhalten.....Mahlzeit... bei Kurzschluss ???

I've repaired quite a lot of them. As long as the CPU isn't shorted, it's in most cases perfectly possible to repair them. They do not lock. I'll try to make a video about it.

nice video btw

So isnt good idea to place some heatsinks on those parts?

LEDs 2 und 4 blinken. Was kann der Fehler sein?

1:41 bewundernswert

I have a battery that switches off after riding for a few minutes. I'm inclined to think it's a temperature issue due to bad cells. But perhaps it could be something with the bms. Do you have any thoughts on this?

Wenn man ein Video stiehlt sollte man wenigstens die Quelle erwähnen 😢👎👎😥
