[Solved] Goclever Electric Scooter Shuts Down During Ride, Requires Charger Reconnection

Hello
I have the same problem on two identical e-scooters.
The problem is that the scooter turns off immediately after trying to ride.
Sometimes it will run for a few meters and sometimes it will turn off immediately.
The strange thing is that to turn it on, you have to connect it to the charger for a second..
did anyone encounter such a problem?

Hello - please charge the batteries fully (until the charge indicator indicates
fully charged) - and then check if it starts.
Please write what are the batteries (type, how many volts)

Hello
The scooter, whether it is fully charged or half charged, behaves the same
Battery li-ion 18650 36v battery capacity 4.4ah

Hello - one bad link is enough and the system disconnects the entire battery.
What does the charge indicator show when the scooter turns off?

Added after 31 [seconds]:

Everything goes out suddenly. The display shows nothing. The strange thing is that to start the scooter you need to connect the charger - 2s is enough. The display shows the battery charged all the time even when I turn it on again.

Please tell me how old is this battery?
Everything goes out, the display shows nothing? , and battery icons what they show.

Added after 50 [seconds]:

Both scooters are 3 months old, display shows full battery...
scooters just suddenly turn off and you can't turn it on. Only connecting the charger helps in a circle

Added after 51 [seconds]:

The display goes blank and shows no signs of life

And was there an attempt to turn on the scooter without loading it, i.e. lift it up and turn it on?

Looks like a dead link, but both?
If they're 3 months old, it's probably under warranty. I wouldn't even try to find out why.

Unfortunately, we do not have purchase receipts. (Presents)
That's how I tried to start by lifting the wheel and it does not turn on.
The only thing I noticed is that when the scooter is turned on, hitting the wheel on the ground also causes it to turn off more than once (not every time).

It would follow that the problem is the connection with the engine ... Maybe something just doesn't make contact, broke off, doesn't make contact? Need to check. Guessing is fun, but not in electronics.

Hello, I also have the same problem with such a scooter, I was thinking about replacing the battery, but I don't know where to buy one.

Hello
I am a serviceman of these scooters, in case of any help, please write a private message

Down krafaello After all, you can ask donors for receipts.

Who do you mean donors?

I wrote who the post is about. Giver - someone who makes gifts.

Hello, I have the same problem. I rode my scooter 89 km in less than a month and this problem started to occur. So it's probably a manufacturing defect of the entire batch.

This issue affects all users of this sell from goclever. The company does not carry out warranty repairs and intentionally damages the advertised equipment. They tried to stretch me on a mechanically damaged display, which was in perfect condition before being sent to the service. I did not agree to its paid replacement and asked for a return of the equipment. The scooter returned from the goclever service with a broken display. They probably smashed it with a hammer because the glass elements completely flew out of the binding and the keys were dented. I recommend avoiding the products of this spawn with a wide berth because it probably trades in waste from Chinese factories. From the remains of what was sent to me, I will try to assemble some ride, if I come up with something, I will share my experiences.

Well, did anything become clear? I have a similar scooter at my site and the problem is the same. The scooter spins the wheel without load (it is known that the wheel must first be moved to start spinning) but it turns off under load. Connecting the power for a second allows the scooter to restart.

I took out the battery (consists of 24 18650 batteries) and interestingly, disconnecting the battery for a second gives the same effect as connecting the power supply, i.e. you can start the scooter again for a moment.

I combined whether the problem lies in the batteries or in the controller that is included in the battery package. After connecting the package directly to the electronics of the scooter, everything seems to work normally, I did a few rounds on it.

Now the question is whether the problem is caused by the controller (I even replaced all four mosfets, but the effect is the same), or the problem is the cells, or rather, for example, one of them - the controller cuts off the power supply when the voltage difference on the cells appears under load (??? ???)

Any ideas?

@koli_koli Yes, there is an idea. Fully charge the battery and load it with six H4 / 12V halogen bulbs with parallel filaments, three bulbs in series, and together in parallel. It will be a reliable battery test - 540 W.

Where is "indirect"? This is to check the battery socket and plug, the circuit breaker and the fuse socket, if present.

Hello
The wine is in the cells

I had the same. One link damaged. Disassemble, measure, replace.

Well, the bug was found. In my case, the fault was not in the links, but in poorly made solders. The socket to which the wires from the pluses of the batteries are connected has been soldered only from the bottom, while the board itself does not have a bridged top and bottom in this place. The effect was that the multimeter showed the correct values on all cells (measuring on this socket), because the multimeter itself gives practically zero load, but with a higher load the contact was too weak. It was enough to solder from above and the scooter is running.

Let me know how it is with this goclever

I will also add another thread about this pseudo-company:
On the 3rd day of use, the deck of the scooter broke !!!!
By the way, the question is, is there any electrician's service in Warsaw or around where I can replace the deck with a new, more durable one?
If not the center, then anywhere in the country? I travel a lot around the country, I can drive with it, and I am determined to have solid equipment.
I warn you right away with advice and suggestions regarding guarantees and their service.
As for the warranty, I prefer to avoid it - it was very slow, I will probably hear that it was my fault and they will replace it with a similar deck, which (it seems to me even to a layman) is poor in material. With the rest, she was with them once after the purchase because they sent a damaged display (the monitor was spilled)
As for the electronics, fortunately it works - still - but the mileage is only 20 km.
Money thrown down the drain - it's good that I'm fine and it didn't happen at max speed but when I was moving.

Well, still on topic. I solved the problem of the broken deck on my own, but now it doesn't load it. I plug in the power and no response.

did you weld?

No, I replaced it with a new one much more reliable.

Is it the socket in the battery pack or the socket on the cable going to the controller and soldering inside it? It's a pity that the colleague did not take pictures of the successful repair ...

In my case, the scooter turns off under the influence of shocks. In the workshop and without a load, the wheel spins without problems.
In the repaired copy, the LCD was damaged (cracked and spilled) under the influence of a really light knock, which confirms the crazy quality of this part...

I plug the charger into the socket and it does not work - just. It was given to one of the electric scooter repair points - I'm waiting for the repair and cost estimate.
As for the deck, well, I also found a point where I was simply exchanged for a new, better and stronger deck - there was no other way out
