Brammo Empulse / Motor voltage
« Last post by Fred22 on March 10, 2025, 12:49:45 PM »
hello friends, i have a b40 problem in turn. i plan to switch to a 3.2v 200ah battery pack. But at the engine level what is the accepted voltage just 104v or can we apply a voltage of 90v or 114v like the zero?
Thank you in advance for your answers.

There might come a point in time when I start rebuilding the modules with new cells which can replace the old ones keeping the same BMS.

And: "Don't ride a dead battery!"

I have seen it live on Saturday and Ive got the same opinion: A great colour scheme for the Empulse!!
But also given the discussions we had live in person during a forum meeting at a cafe I guess ways_ahead will think twice before continuing revival of his batteries...

As my favourite doctor used to say: Its dead, Jim! ::)

All,

at first kudos to @KaFr and @ways_ahead for the 24/7 support via messengers.

Time for a little update on my revival project.

I am member of a german forum www.GoingElectric.de since almost 10 years. This forum is car-centric but also has a motorcycle section. For my local area there is a forum meeting organized in a cosy little cafe on the outskirts of a smaller city every four weeks - an ideal place to present my charger issues and have the experts look at that thing and come up with suggestions.

Unfortunately, the findings did not really lead to a solution but maybe it might be of interest for you what the experts were concluding on:

I brought the charger electronics for visual inspection and also a Fluke multimeter in case something should me measured. Actually, the inspection showed that there is no suspicious part. Everything at least looks like it should work perfectly.

I also brought a larger printout of the wire diagram which we analyzed.

When the charger is connected to AC, the signal AC_sense is on high level. This signal goes into the VCU in connector C-01 Pin 15 as U2C Charger_AC_SENS. We believe (!!no fact, assumption!!) that the VCU has the task to check if charging conditions are valid. Could be done like temperature conditions, undervoltage. See my initial post where I mentioned the dashboard shows severe undervoltage. It looks like then the VCU signals back to the charger a signal on C1 (VCU connector C-01 Pin 27) - probably HIGH. The charger may start charging. There is also a direct signal between VCU and the Batterie RS485 bus: Pin 26 Charger enable. However I have not yet found a method to tap into that signal to see if it is there or not. But I can perfectly measure the connector C-04 on the disassembled charger.

This is what I have observed (it took me a while to figure out how BBCode works  ;) ):

Pin C-04   Key-Off   Key-On   Charging
1 - NC...
2 - FanPWR_Out   +1.15V+1.1V+1.15V
3 - FanPWR_inGND+12V+12.5V
4 - AC_SENSE+1.44V+1.45V+9.4V
5 - WARNING+1.5V+1.5V+1.5V
6 - NC...
7 - BATT -.closed.
8 - NC...
9 - C2openopen+0.6V
10 - FAULT+1.5V+1.5V+1.5V
11 - C1openopen+0.6V
12 - NC...


Ladies & Gentlemen, now its your turn. Please help me! What are the proposed next steps here?

Brammo Empulse / Re: 2013 Empulse Sprockets
« Last post by empulsefan on March 08, 2025, 12:41:52 PM »
I replaced the rear sprocket for an alu-version :o
not much driving, not the most agressive rider but I'm looking for a steel one.
Would be pleased with a 76 hole, 5x10,5(or smaller)  and kan be thicker(I'm a grinder)
Plan B is to order from a supplyer a couple of laser(water)cut pieces.
Anyone know what material is used for these sprockets/

Greetings,
Gerry
