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.
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?
I'm using an electrical load DL24P to test battery pack without Bosch BMS, but with an unprotected BMS. DL24P alone is limited to 150 W (while real motor is 250), but it is enough to perform the test and obtain estimation of remaining capacity.
Then, I'm using a 10S1P home made battery, in order to perform several BMS tests (diode, ...) , using videos on youtube made by HardwareJunkie (in German, but very very instructive).
Hallo, ich habe eine Frage : Muss ich die Schottky-Diode ersetzen, kann ich das Bosch BMS aus der Batterie entlöten? ( nach dem Ausschalten des bms von der Bosch Powerpack 500 funktioniert das bms dann wieder, ODER ?) Danke für die Antwort. Abonnement und gefällt mir . ;)
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?
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?
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
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.
How could you fixed ? Is possible so fix, when the TPS57160 is "shorted" , and has same output voltage than input? I think in this case the full battery voltage goes to contorller ICs?

@@wim4245 Thanks for your replay, i merasured 6 ohm "sortcut" on the 3.3 volt line, this is the power rail of the MCU. i connect 1,8 Volt to this line, then the MCU started to get hot. I don't remove the MCU yet, to check. do you know anything about the "legend", when disconnect the batterys, the MCU "kill" itself ?
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.
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
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?
Mine is the same, I haven’t found an answer yet…I bought a new 400 pack, but am determined to repair the first one, if you have any tips please put them on here.
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?
I think &realized there is most of time no connection between Positive of Accu to positive of circuit board,some where diods or chips damaged of not working.What happens if charged accuse are directly connected to Mains of Bike without circuit board.

@@harryboyer8858 i understand testing with electronic load bit that's before the bms so you still don't know if they bms works

Hi can you tell us how to charge this bms with normal charger ....thanks.
can you tell me where i can get the blue cap next to the diod

How to have output without original ebike connector?
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
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 ?
Se sont les cellules qui sont faibles et ne veulent plus prendre la pleine charge, des fois c'est juste 2-3 ou plus accu HS ds le pack de 40 cellules
LEDs 2 und 4 blinken. Was kann der Fehler sein?
What is the three pin plug?
Hi, do you have any experience with BMS with 5 leds flashing. cca 3s on 5s off
Thanks
Super Infos, vielen Dank! Kann man ein BMS eigentlich komplett irgendwoher beziehen, z.B. weil irreparabel?

Hi it sounds like you have a brak in your battery, check your contact in battery
I have 3 boards for Bosch can I send them to you to see if you can fix them
Where can I get the diode from is there a specific one?
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?
Si potrebbe vedere il video in italiano. Per sapere sul bms bosch.
o una scheda che non si accende 500w ci possiamo mettere in contatto
Können Sie meine Platine reparieren?

@johan A Bosch powerpack? Do you get an error message (like 640)?
@@wim4245 no no error message. Sometimes the km/h reading shuts off including all power for a few seconds. Or the unit just switches off
@@johanmartinsson680 Sounds like a bad connection in the connector or wiring loom. Could also be the early stage of water damage.

They can be swapped with another BMS: ruclips.net/video/jRkLBh6oztg/видео.html
Yes that's what i do to but you still need and original bms for Bosch , i would like to swap the bms with another brand of even chinese bms
⚡👍⚡
nice video btw
1:41 bewundernswert
Wenn man ein Video stiehlt sollte man wenigstens die Quelle erwähnen 😢👎👎😥
I need a replacement BMS
Any luck finding a source
