bafang bbshd firmware update

Very well explained programming settings. I know that will work with 30 amps. I am looking to make my 0 level about half as powerful as my 1 level, as 1 makes it too easy for me. You could also try a different pc/notebook, sometimes one works and the other doesnt. Or did it work for a short amount of time? BBSHD Programming For The Pedaling Cyclist - Tales On Two Wheels Will see how it goes tomorrow. Lessons learnt! I have two questions: The reason why your new controller feels slow, is probably because the current limit is set lower. It could indeed be bad luck, and just the randomness of failing with these Bafang controllers. A 17Ah or 13Ah will definitely not give the same range, at the same speeds. https://github.com/danielnilsson9/bbshd-fw/wiki/Flashing-the-Firmware, Configure What current limit (A) i can put on the first page, I mean, what is the maximum number? Only change the setting Wheel Diameter[inch] to your wheel diameter, leave the other settings unchanged. If you want 5 stages, you should still fill in the 9 assist levels, I believe it picks assist levels 1,3,5,7,9 as the corresponding stages if you choose 5 stages. Try the obvious like testing on another pc. Ich kann Ihnen leider nicht mit Ihrem M500 Motor helfen. You should be able to set those numbers. And if you want the motor to stop straight away, you just hit the brakes. I use the following tools: The setting on my display(DPC-18) from the factory is 29 but my bike has 26 x 4.8 MAXXIS tyres. The idea it to save more battery power by having the motor run as if the battery is a 48V battery. Last edited by amberwolf on May 12 2019 3:41pm, edited 2 times in total. The controller and cooling of the BBSHD are better than the BBS02. I can load it fine, but the numbers are all wrong. The Bafang ultra is really powerful, you therefore might want to increase some settings, to get more power. originial (confusing) instructions.txt 4)plug in usb to laptop after 5sec sign in 12- Turn on the batterys power switch. The only reason I ask this is because I think that was the default and I test rode it before playing and finding that I can change the voltage to 52V. In general, a full 18650 has a voltage of 4.2V @100% and a voltage of 3.2V @0%. Franco But it is possible to do. I have a bss01b 250w motor. I cannot be held responsible for any injuries caused by the use of this firmware, use at your own risk. But since the programming doesnt work as well, I suspect that your controller is faulty. Bafang programing cable - Available here on Amazon or here on eBay. I have an M400 250W Motor, 557 Wh 48V battery. Thats definitely something that would be very convenient. You can always try to get the chainring as close as possible with spacers, custom adapters etc. I dont want the throttle to work as soon as I switch on the display. More correctly, sometimes it goes, but sometimes no. You will often experience that you will have clearance and chainline issues. All other settings should work fine with a 48V battery. I either get all or nothingthrottle if I set to the throttle to recommended Designated Assist 9 or the default Biktrix settings which pairs a throttle limit to Pedal Assist level. 2) I would be curious if I can just use my 52V battery and change the controller to be at 48V system? Ich hoffe, Sie finden etwas heraus, das fr Sie funktioniert. If not: do you know a way to change the settings of the M420? theres a ton of stuff to read up on the internet! Bafang BBSHD Configuration Tool HOW TO - YouTube 0:00 / 7:19 Bafang BBSHD Configuration Tool HOW TO Doug Hnut 12.6K subscribers Subscribe 1.3K 86K views 4 years ago In this video I will show. It kinda stalls at first press and takes a few seconds to get the bike going even at a slow 10km/hr. The interesting thing is that YES, the programming does indeed work. I have a Bafang 750W BBS02 with 48V 17.5Ah battery fitted to carerra subway 1 with a 8 speed rear cassette and a 44t chainring. Thanks. I also have no experience with this kind of reflashing. I recommend 36, since this is the default and in my opinion, works perfectly. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. You could also just lower the speed limit set on the display to a speed at which you can still pedal along. If it reads to 20A default, this is absolutely fine. This is true in the sense that the speed limit you set will in most cases be hit first. https://drive.google.com/file/d/1rerH9mTJQfyJcuiB5atlN_aV99v8UBij/view Hello! Bafang BBS02 and BBSHD Programming Cable I want the throttle to take off quickly. Warning: The firmware should NOT be flashed or configured while the eBike battery is charging! It indeed is more likely that its a problem with the gears inside your Sturmey-Archer hub. I hope that you are able to fix the problem. The hardware is limited to 25A though. The pc is not compatible for some reason (try another pc). For now I dont see any obvious problems, it should just work. The combination or clarity and comprehensiveness is why I love reading articles here . 26 (to reflect the size of the drive wheel) so that i do not do damage to the motor? Thanks for letting me know. And soon I will get new controller that I already ordered). I have now changed the link, it should work now. If the controller works fine for the bike part, I wouldnt replace it though. The main aim is to be able to carry a lot of work gear etc. To use these configurations you need to follow the following steps: You first need to back up your default settings. The low voltage cut off doesnt affect performance. 30-40Km/h If thats the case it will be a waste of money. This also is the only way to change the read out. 20 inch wheels are rather small, the smaller your wheels, the less top speed. My programming cable will be here Thursday so you will probably be sick of silly questions from me by Thursday evening. So if you are not planning to ever use the Bafang BBSHD 1000+ watt power, I should buy a less powerful cheaper motor. The sensor should be attached to the wheel that the motor drives. About the second question. What settings do I tweak differently for 36V, 500W, 25A, BBS02? If you decrease slow start, you will accelerate faster. Thanks. Can I plug n play a throttle without reprogramming the controller, 2. This way I send the serial data over USB via a raspberry pi. Unfortunately, I dont have the knowledge nor experience with serial communication methods to help you. My display 500c have different voltage setting ( 36, 48, 52) but all show 76% when the battery is full. If you have another Bafang version you cannot use these files. 9b- Disconnect ebike battery from BBSHD This is the case because the display will think that you use a 48v battery. This allows you to work with your saved profiles even if you haven't connected your bike. But if you would like to have throttle in PAS 0, change the current limit of that assist level in the Basic tab. UPDATE: The BBSHD is programmed in the exact same way with the same software as the BBS02. Yes, you can change it to speed mode, thats no problem. All the feedback Ive been getting is that the m400 cant be reprogramed out of the factory? I found a write up on programming the Ultra Max, which is Bafangs M600. This way you have amazing control over the amount of power. Hi Kenneth, your battery definitely is a 52V battery, and your motor is 48V. But if you do this, you will only have 250W power ofcourse. Thanks Giel . I have no experience with this motor in specific, but I think the only settings you can change are the settings that can be changed using the display. Its just a different look. After that you only have to change the number of stages on your display from 9 to 5. http://s.click.aliexpress.com/e/_d6qjlWU. But if you are able to sensibly shift without the gear sensor, you should be fine as well. my display gives me a high voltage warning, and I have to drain power by recharging my iPad, iPhone ad etc., until I get down to about 56.4v and that takes hours, then my motor will run. I would suggest trying yet another pc and trying to install the drivers again on the pc you already tested with. Thanks for that. . Please could you try and help me? Try a different pc, different cable, different order of connecting to the controller, etc. Lets see: It should have it right? This firmware is intended to replace the original Bafang firmware on the BBSHD/BBS02 motor controller. I will try to answer them within 24 hours. You should measure your battery voltage, to check if its right. So i ventured into the programming today. Ive downloaded the drivers for the USB programming cable but still cant seem to communicate with the controller. Using this cog I put throttle to max. The BBS02B is the newest improved version. Hi Giel, that is correct. The speed limit is overwritten by the throttle, so you will go as fast as you want. I had a light on the usb lead but But software says communication error. My kids both have legit mountain bikes as well. mijn vrouw heeft een amslod met de M400 die ziet hey wel. Do you know what the difference is between the BBS02 and the BBS02B ? JavaScript is disabled. Thanks Steve. Tongsheng TSDZ2 vs Bafang BBS02 Which one is for you? Add Comment . No, underpowering will not put any strain on the electrical system. If you want all the power available, set it to 15A. What I meant with controller programming part is broken is that the physical circuit board responsible for programming is broken inside the controller. I have the cable provided by Bafang that I connect to the display cable as described, I installed the x64 win10 version of the proposed driver. Can it be changed with the programming cable. How long had you had this controller? Currently, Im using the config tool and a USB sniffer to see what serial data is being sent. Its not a big problem that you already bought a replacement controller. If not, what are my options for using a throttle on this model, 3. It will inevitably be some trial and error process. If this is not stated, you can easily calculate it yourself as demonstrated. https://bafang-e.com/oem-area/components/component/motor/rm-g060750dc/, https://www.youtube.com/watch?v=WNmvj9PiZ08, https://www.dropbox.com/s/0ak55h0vmhwe1hm/BafangConfigTool.zip?dl=0, https://drive.google.com/drive/folders/1bBOGwk5FauKVbFH0n-nvE_cDWb-SCHCr?usp=sharing, https://forum.velotaf.com/topic/28285-programmation-kit-moteur-pedalier-bafang-bbs/, https://electricbike-blog.com/2017/11/23/i-void-warranties-hacking-the-bafang-ultra-max-mid-drive-ebike-drive/, https://endless-sphere.com/forums/viewtopic.php?t=93000, Connect the programming cable to the display cable, Plug in the battery of your e-bike (and turn it on), Plug in the USB cable of the programming cable to your desktop/notebook.

The error code 30 is probably also the cause of why the programming doesnt work. I do know that permanent magnet brushless motors like the Bafang motor most of the time will operate more efficiently at higher RPM. (Limited to 0% current). Id like one level to only respond to the throttle, no pedal assist. One issue I can think of, is that the programming cable might not function correctly. If you want less power, you should decrease this number. So you can definitely get more power out of your throttle, so that you can accelerate faster on busy streets. (19.86 KiB) Downloaded 869 times. Its a shame that controller failures are rather common with the Bafang mid-drive motors. So if the current limit is set low, the motor will not be able to turn the chainring with a lot of force. 125 posts 1 This firmware is compatible with all displays that works with the original Bafang firmware. I noticed the speed sensor is connected to the front 20 wheel. So there indeed doesnt seem to be anything wrong with your battery. Herv, The configuration: Thanks for your answer Giel . What you need to check though is if the cut-off voltage in the programming software is set to the correct value. Thank you!
