A new speed controller improves my DIY electric scooter to support regenerative braking and battery protection. The VESC provides a ton of options to control the hub motor. A simple analog stick is used a throttle now. Enjoy!

So you printed an enclosure for the 0,70€ Throttle Stick but not for the 80€ ESC?

I think once you burn up parts on the bench, totaling double the cost of a new scooter, there are no longer any rules.

@NiHaoMike64 5 лет назад

Looks like a fuse would have been a good idea, especially during testing.

@simonlinser8286 Год назад

Fuses are always a good idea, aren't they?

@pirateman1966 5 лет назад

You should install a strain gauge under the stand. When you are on the scooter, everything works as it should. When you step off, it should apply the brakes. Like a dead-man's switch. I love your workmanship. So German!

@bardenegri21 5 лет назад

The motor current in the vesc settings is the current at 5v or whatever it sends to the motor, so it can be larger than you'd think. You can set it higher and limit the overall current with the battery limit and the total power limit (in watts). Also, I'm sure you figured out FOC mode is way better than BLDC mode (pwm). Good stuff

Questions: 1) I hav an escooter but no regenerative braking. Do I need to change the electronics? 2) I want to change the electronic braking switch to the known bike braking, but still retaining the electronic braking system, it's just the switch that changed, is that possible? I want to see how you do it.

Hi! Is it possible to make a simple brake with the original controller? Please reply.

@furulevi 3 года назад

Hi, I just increased the regen braking value on my scooter and now it brakes much better downhill. The question is will this increased reverse energy hurt the battery or the controller? Thanks!

@bitluni 3 года назад

you need to check the maximum charging current of the battery. i'm not really sure how harmful it might be to any of it. the controller should have protection but I had a few blow up on me because of reasons i still don't understand

@dimitritzer5028 3 года назад

Think you can connect it to an arduino, and do your magic with that :D

@NamacilHDx 5 лет назад

Just an idea ... the breaking current is quiet limited by the lipos usally they dont really like to be charged with more then a few C ... so i imagne a capacitor bank and a current limiter or something like that ... that way you can breake with way higher current and simply charge up some beafy capacitors wich then slowly charge the batteries from the breaking if i think about it a emergency resistor to just pull the caps low if the caps dont decharge fast enough befor an other brake all that would give more breaking force xD

@Mastermoussa 2 года назад

Hi, da du dich ja scheinbar echt gut mit dem Thema auskennst und wir zwei unserer Maiwagen motorisieren wollen, wollte ich mal fragen ob du für einen 350w 36v Motor einen guten Controller empfehlen kannst, damit ich alles simpel verkabeln kann (Batterie, Daumengas, Motor) und evtl. sogar schon mit regenerativer Bremse (hab mal gesehen, dass es wohl Controller gibt, wo man einfach einen Hall Sensor anschließen kann und damit dann regenerativ und vor allem dosierbar bremsen kann) (also mit simpel meine ich, dass ich nicht noch programmieren oder sonst was machen muss, sondern einfach die passenden Kabel an die Komponenten anschließen)

How long did your second (flipsky) fsesc 4.12 last? I bought two of them last week and already broke both, ordered two more though and will be installing them later today on my electric skateboard. I was stupid like you and I'm pretty sure it was entirely my fault why they died. I set up the settings on the VESC tool way beyond what my setup could handle. I'm hoping this time around will go much better 👍

@Pryside 5 лет назад

You will burn up any vesc in no time on high erpms, solder a P6KE56CA tvs diode directly on the vesc pcb battery input, otherwise you will destroy even more vescs, trust me I had to go through 5 vescs before realising the engineering flaw. If you want to be extra carefull you can add a EEUFR1J681L ultra low esr cap, will help as well with the survive chances of your vesc

@avacreativemedia 5 лет назад

Leo Pryside I agree it’s not a very “reliable “ or “robust “ esc the Vesc I went through 3 of them just on the bench in the end I sort of got fed up with them - maybe the TVS might have helped them not self destruct 😉

@tedhancock68 3 года назад

Sometimes the USA is still the place to be. I looked up local regulations and all of these devices are considered "motor vehicles". In other words a policeman is more likely to say "get a bigger motor...loser!" than "I'm giving you a ticket for going too fast." If you can't go 40 Km/h, you need a special sign.

@JDrwal2 3 года назад

It appears that the links you provided for Bitluni (?) VESCs and other components on Aliexpress do not work. Could you let me know the name of the manufacturer of those VESC is and the model number? Also... would you know if there are VESCs that get good support from the manufacturer, including customization? Thank you!

Here in the UK these 'e-scooters' are illegal to use on public roads. A 35 yr old lady was killed on one in London just this week. Are they legal in Germany?

@geekmystique 5 лет назад

To my research: They need to be certified safe (lights and brakes), furthermore insurance is required (including a small license plate) and kids are not allowed to ride them. It can be compared to the laws for light scooters and throttle ebikes.

No. So it's funny that he mentions removing the push detection because of the new law but ignores all other new requirements ... ;-p i.e. to get it street legal he has to add lights, two brakes, max 20 km/h + 500 Watts limit and he needs to find someone willing to give him insurance.

Facebook Marketplace is full of "dead" scooters, hoverboards and other devices. A hoverboard yields two 350 watt brushless hub motors and two pretty good, flashable ESCs. Not to mention about 28 good 18650 cells. I buy the hoverboards for 10 USD each. The last batch had 400 watt motors and one was working perfectly.
