My drive (rear) wheel is 26. If you take good care, nothing bad should happen and you can really customize everything to your liking. So I would in practice just choose the gear that is most comfortable to pedal along with, it might be a bit less efficient, but it does make riding the bike much more comfortable. Cause I cant find any settings for bss01 . TommyL. Yes Im running 48v. This has to do with the highest gear ratio of the bike. If you increase the power, the torque will increase, but the speed will increase as well. Which often is more accurate than the display does. However, it always appears blank with dashes: Range - is there a way to program the controller so it displays the range left on your battery? It should have it right? After 8 months of various tests I give you my configuration for my electric bike Fischer ETH1861, Bafang M400 motor, Battery 557 Wh 48V / 11.6 A This can be simply done in the display menu. I had a light on the usb lead but But software says communication error. A new controller costs around 80-90 USD, so it probably isnt the cheapest option. Its a shame that controller failures are rather common with the Bafang mid-drive motors. When i try to save to flash with 30 amp it give fault to high current or something like that. Check if these settings are set to my recommended values. Yes, the speed readout would be nonsense, but the rest of the motors performance?? I normally try to do this but is not always possible Re: BBSHD Voltage Problem Firmware Update & Instructions Quick question. The low voltage cut-off will engage at 36V. This is absolutely no problem and can be done without straining the controller. It rode ok on pavement, but was worthless on dirt trails. Current A was 20A BBSHD unpotted Display Power Line.jpg README.md STC15W4K32S4-en.pdf README.md Bafang_BBS02_BBSHB 48T Front Thanks. zie wel de voltage maar niet het bereik de RANGE is dit een fout of hoort dit zo Hitting the magnifying glass will automatically select the correct port. The new BBSHD controller is limited to 28A instead of the old 30A. These things can be changed. Cheers Giel! If you decrease slow start, you will accelerate faster. Im using the Luna Cycle Bafang software (the link to the bafang software on this site doesnt work for me) Maybee the Luna program is limited at 28 amps?? Most of the time, if something is wrong, the load function will not work either. If the bike still shows weird behaviour with stock firmware, ebrakes and shift sensor removed it indeed probably will be a faulty controller. 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. Bafang programing cable - Available here on Amazon or here on eBay. So make sure, your highest cassette gear, is 11T. This is how the controller calculates speed. I was really annoyed as I was happy with the way the unit was performing and all I wanted to do was save the settings on file!!!! I do not have PAS setting in the display. So such a mod doesnt make sense on the Bafang mid-drive, it isnt necessary. Anyone have any more news? It would have been amazing if you could reprogram the hub motors as well. If you follow the steps of this video, are you then able to set it to 9? I recommend 4 because this results in a responsive system. So in that case, the battery percentage indicator will be useless. If you have a newer BBS02B you are probably fine, if you have an older controller it might not be a good idea to flash this firmware. Hi Kenneth, your battery definitely is a 52V battery, and your motor is 48V. BBSHD/02 Firmware Upgrade $99.00 Many BBSHD/BBS02 motors by the Bafang Corp came with a flaw in the controller firmware which causes a jerky interplay between the throttle and PAS inputs. But the difference is that the entire firmware needs to be reflashed. Alternately it is also attached as a .ZIP file you can extract the .bin file from. Most of the time you will have to press some button combination so that you will enter a special menu on your display. A fully charged 48V battery would he 54.6V. and Id like to use PAS in 5 stages, not 9. In practice you will always match the motor RPM however, because otherwise you will feel that you are not applying any pedal power immediately. Have a good day all. Thank you for working all this out and sharing! Its incredible powerfull and will tow anything uphill with ease. Ill see if I can find an accurate gps speedo and match of up to that. So I am curious if you were able to do that. By the way, my controller has been completely recovered. If that all doesnt work, it could be the case that the controller is faulty. Having more drag on an e-bike is normal. If you have any questions, please leave them in this comment section. Bafang BBS01 250w Review Best street legal conversion kit? Bafang 1000W BBSHD Mid Drive Ebike Motor Kit Bafang BBSHD Configuration Tool HOW TO - YouTube BBSHD firmware | Electric Bike Forums - Q&A, Help, Reviews and Maintenance There isnt a way to change this with software. Do I understand that the usable range in my battery to 100% to 41%? You can adjust all other settings to my recommendations in this post. You just pedal along in the assist level that you find that gives enough assistance. Make sure not to hit full throttle in high gears or on a steap incline. He has responded in this comment section as well with some tips on this. The known is that in PAS as long as you are spinning the cracks regardless of RPM, the controller will keep sending current to motor until the speed limit is reached for PAS level. l. The displays setting will probably overwrite the configuration tool setting. Die Mglichkeit, dass Sie etwas braten, ist dann ziemlich hoch. You should set this at 44 instead of 41. So the throttle wont work either. En effet, je ne sais pas si le M400 est en BB-32 ou Double signal 24. Bafang BBSHD Nylon Reduction Gear ; Bafang BBS02/BBSHD Main Wiring Harness ; Bafang BBSHD 1000W Upgraded Aluminum Chainring ; Bafang Front LED Light ; Bafang BBS02 Bling Chainring ; Bafang BBSHD 1000W Controller ; Bafang Gear Sensor ; Bafang BBSHD 1000W Bling Chainring ; Bafang Mini Color 500C Display ; Bafang DPC-18 LCD Display ; Bafang BBS02 . Thats really unfortunate. Be mindful of the fact that you can damage or burn-out your controller if you accelerate from standstill in too high of a gear. You could try to set strart degree to 0. So lets say you climb a hill, in the highest gear, without pedalling with 5% current limit. Thanks for letting me know. Is there any remedy? If you follow the steps, it should work. All this time I thought I had the BBS02 but I do NOT in fact I am not even close.. How did you manage to change the settings on the Bafang M400? But if you are able to sensibly shift without the gear sensor, you should be fine as well. I think a better approach would be to set max speed just above user preferred rpm. 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. . To use these configurations you need to follow the following steps: You first need to back up your default settings. So Ive set 78% for max speed of all PAS and used your suggested % for current limit. Hi, Problem Im able to connect the USB cable, it shows on the configuration programs as COM3, I hit connect it shows connected, but the Read button is remaining gray and no info is coming from the controller. BAFANG | Home Your power will increase, but the reliability will decrease. Do you think my laptop isnt compatible? https://github.com/danielnilsson9/bbshd-fw/releases, Install 1) If your controller has a connector that can take a throttle, I would say that it will definitely work without reprogramming. The gears are aligned good, nothing is bent. Such as start current and slow start. This setting will decide how much current the motor will draw on startup. Alright! And even it goes it can stops at any moment. Order Numbers should be 6 or less numbers (Examples: 1234 or 123456) Message *. User avataramberwolf 100 GW Hi, There are some displays that support a 52v battery, and therefore can give a correct battery percentage. Hope this helped you, if you have any further questions, let me know. Is there any other way to turn the battery back on? Hello! Both modes will have the same behaviour. We now can indeed confirm that the sport and normal mode are exactly the same on BBSxx systems except for the color :p. Thank you for this post! The drivers are not properly installed. (Note says that FTDI based USB-serial adapters work well, but I assume you MUST use a USB-serial thats got the right connector for your BBSHD, presumably the round 5 pin green Higo). A wrong sequence also should not cause a controller to fail. This firmware is intended to replace the original Bafang firmware on the BBSHD/BBS02 motor controller. Therefore I think that the efficiency difference in different gears is not that big, but in general, a lower gear will be more efficient. I Understand your question but will have to look it up and check. Weet jij waar ik deze modes kan configureren? If you increase slow start, your start will be really slow and jerky. Thanks Zeeshan, ill give that a go and see how i get on. Top You can try to reset to your default settings, and see if it still happens. A 10.4Ah battery is quite small and unfortunately doesnt give you all that much range. Hi Giel, Some questions about my bike range. By setting all the other assistance levels (0-1-3-5-7) to 0 (zero) the controller works perfectly and selecting the 5 assistance levels from the display changes the motor rotation speed. I have set the settings the same. If not, what are my options for using a throttle on this model, 3. I recommend current since this is easier to calculate by your controller. Leave this setting to 11, changing it can give problems to the response of your throttle. Is this normal? This feature protects your battery and is essential to have. When I open Bafang_Programmer.exe I see COM3 displayed. So say that for example the current limit in assist level 5 is set in such a way that the maximum power while cruising will be 500 watts. The message from the executable was that no serial connection could be established. After driving about 40km I will have about 3 of 12 battery capacity indicators left. Hi, If you want it to be around 350W, set it to 10A. 3 Insert the programing cable (USB-Serial Adaptor) into the computers USB port, and install whatever software it requires. I dont know for sure if it can even be reprogrammed. Thanks for reply. User avataramberwolf 100 GW Now click Read flash in the right bottom corner of the program. Herve, have you been able to get yours working properly? So I recommend just leaving it to 4. It sometimes help to try another computer, but you already did this without success. At first it worked strange, power jumped from 0 to max at any level, but now it works correctly. But in practice this will mean that your useable range will be less. So you cant really increase range by changing some settings. I am close to buying a Bafang MId Drive kit. 5/76/58 28 amps is the max i can save. BBS02 firmware required - Electricbike.com Ebike Forum The weather is supposed to be so so over the weekend too so hopefully ill be able to tune it, then try it and adjust as required. Close to ordering the programming cable and start having fun with my bike as well. Questions: I suspect this only happens in the highest gear? Can I keep the other suggestion values that you recommend in this post to improve my experience of riding, I usually use my bike for mountain terrains. You cant actually change the allowance for 52V using this programming software. If it also doesnt work on another pc, please let me know. Your controller programming part is broken (have had this issue before, but unlikely). I have not viewed the following link; presumably it is a video version of these instructions: https://youtu.be/6fvJVz30LU8 Only in first gear when applying throttle the engine cuts out until applying more throttle, then cuts out again, until max throttle is applied. If your battery voltage drops lower than the number assigned in this setting, the motor will stop working. I just reprogrammed my controller so I need to test to make sure Im getting the correct power levels assigned to the 9 modes. Hello Giel, You were right! Lol Bafang DPC-18 LCD Display . The lower this setting, the faster the drive unit will decrease power as you pedal faster. I do not have PAS setting in the display. If you for example set the speed limit of assist level 9 to 50%, it will imply that the maximum assisted speed is 50% of the maximum speed that you have set in the display or in the programming software. Shows Time, Power Assist Level, Trip Distance, Speed. By the way: What is your current limit? The display will often show a battery percentage that doesnt really correspond with the actual voltage. It could indeed be bad luck, and just the randomness of failing with these Bafang controllers. Definitely not the same as when at 50V etc.. Not sure where to look in the settings to adjust. Jai perdu la configuration dorigine et si quelquun pouvait me la donner. Lessons learnt! My friend has the same bafang motor and his monitor shows percentage right (100%). 54.6V is exactly the voltage of a fully charged 48V battery. Good luck! This was the case when I had the display. when I start gives very much power and speed That explains a lot hahaha. This might mix up the signals, showing incorrect load results and the inability to write. Yes you can use the BBS02 500 watt 36V .el file for the BBS01 as well. Its always hard for me to pinpoint the cause of the issue you are having. Is it possible the Bafang controller in the motor is defective? What is your favourite assist level? Hi Giel, Thanks for taking the time to reply to my issues with programming my BSSHD controller. 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. If usb driver is installed correctly the software will find the the com port. I am sure you will find a setup that will work for you. The setting on the display will set this setting and the pedal-assist setting at the same time. Thank you for the great explanations of the settings. If you want a wider range of control with your throttle you can set this to a maximum of 42. I meant if we should do some service work with the motor after maintenance, during exploitation, open it, check smth, grease. If you hold down the + symbol it will switch back and forth from these modes. 7 Change the settings for Max Baud to 57600 and Input IRC frequency to 18.432 Mhz 3. It could also be that it needs some time to change the %, when you changed it in the menu. Assist 6 -current limit 80 speed limit 70 Assist 8 -current limit 90 speed limit 50 Assist 9-current limit 100 speed limit 40 In this way on level 5 of the display I have the maximum current with a reduction in speed I also confirm that the two modes of the ECO / SPORT display are exactly the same except for the color change. Thanks for the reply. This is the case because the display will think that you use a 48v battery. Fantastic!! It doesnt sound like a battery issue. Do you think this is sufficient for my needs as listed above? Example is current at 10% speed at 100% with speed limit set to 20mph. Older versions might still have the 30A controller. I know both batteries are full because the voltage reads 52.6. Bafang does not support any alteration of its default settings and everything out there that lets you get at them is 3rd party and unsupported by the manufacturer. I have programmed to your suggested settings. How to Fix Bafang BBSHD & BBS02 Error 30
