Plugged the mains into my electric moped charger port.

[quackstar84]

Hello I was careless once again. This time I got my charger ready to plug into my moped although all the cables were mixed up and I didn't notice till now that both the cables are kettle leads type ones. Anyhow I plugged the one from the mains into the charger port for at lease 30 seconds. Here's an image;

So now when i plug in the charger correctly it doesn't begin to charge. Would the controller have an fuse? I didn't smell any smoke either?

Thank you for your time.

Blown BMS I would imagine. If you open it up and post some photos the experts may be able to identify a possible repair option.

This is an unfortunately common example of dangerous (and likely illegal) design on these Chinese chargers.

I did the same thing with mine once but all it did was blow the fuse to the battery.
Now I dont charge when returning from the pub

 

[quackstar84]

Sorry I forgot to add that the moped still works out.. it powers up and rides fine. The batteries are fine as well. Just won't charge. Thank you.

If this is a Lead Acid model there are no BMS's.. and the charge port is not going thru the controller.. it's just a tap to the pack terminals... there should be a fuse between the charge port and the battery somewhere, it's the most likely thing to check.

edit : and for the love of god... change that charge port to anything else.... accidents waiting to happen again. of all things to cheap out on they really.. REALLY need to re-evaluate their priorities.

Here's the batteries spec; http://gqgtech.ecvery.com/products/battery-packs/p2146840/12v-20ah-electric-bicycle-lithium-ion-battery-pack.html

It's four of them wired up together. They all gave voltage reading around 12.5v and the total level was around 50v. It needs a charge because it cut out on me due to the battery being low (Possible the BMS on the batterys?).

There was current going from the charge port to the cable box which houses all of the cables together. The cable going to the batteries was screwed together with the cable from the charger port. Would you like photos? I can take some tomorrow. Might be best to take a video.

there is a fuse in the charger lead inside the scooter. it is open circuit now.

 

[quackstar84]

Hello. I did follow the lead towards the cable hub although it's both the positive and negative get covered in a black protector cable so the fuse might be in there. What do you mean about it being an open circuit? Thank you for your support people.

Got this moped to help ease my depression by being able to go to the gym.

Good News! You can save on gym costs now and take up cycling. Unless you only went for the girls. In which case I will come and fix it for you, but only after all else fails.

 

[quackstar84]

I have an ebike but I didn't want to take it to the gym as the battery and controller could be easily stolen.

Thank you very much for that kind offer. I will pay for your fuel cost and time.

I'll get a video of it tomorrow if it isn't freezing outside showing the charger port and it's cables and where to go to.

First, check the breaker at the wall for the AC mains plug you're using to charge from. It might've popped when connected to the battery directly.

IF that reel of cable has a fuse or breaker on it (like in it's plug to the wall or in the reel itself) it could be blown/tripped.

If you're not sure, plug the charger's AC cord directly into a *different* wall outlet that you know works (replacing some other device already plugged in and working). If it now charges, something is wrong with the first outlet or the reel.

If you find nothing wrong in the above steps but it still doens't work, and the charger's lights come on, then:


Get a multimeter with continuity buzzer function.

Set it to that function.

Plug the leads it comes with into the correct terminals on it for that function.

Connect the other end of one of those leads to one of the pins of the charger port of the moped.

Follow the wire from that pin to it's next connection point, and connect the other end of the other lead to that point.

If it beeps, that wire is ok. If it doesn't, either the wire itself or a fuse inside of it's coverings needs to be replaced.

If it beeps, do the same for the next length of the same wire until you get to the battery, if you didn't already.

If all of that beeps, then do the same for the next pin on the charge port.

One of them will have no beep or buzz from the meter when you do this test, and that's the one with the fuse or otherwise nonconnected wire that you have to fix or replace.

if you have a DVM then measure the voltage on the pins in the charging port of the scooter. use the 200V DC scale

 

[quackstar84]

Hello Amberwolf. Thank you for your response.

Yes I used an extension cable reel which had a break on it I think because you could press a button which clicked… I did press it and it did reset it but with no luck. I will check to see if it has a fuse or better yet just use another main’s cable. Yes I’ll also try testing the reel with something else as well.

I’ll check to see if my multimeter has a continuity buzzer function tomorrow thank you.

Many people are very lucky to have sympathetic and supportive members on this site.

 

[quackstar84]

Hello dnmun, yes I set it to 200v dc scale and got around 47-50v which was the same as all of the batteries together. The charger it's self has a fuse which isn't blown... I have another charger for my ebike which has the same specs, it's a vpower one... I check to see if that chargers my moped tomorrow thank you.

 

[amberwolf]

If you get voltage at the charger port on the moped itself, without anything plugged into it, then the problem is likely in the AC mains supply to the charger.

Does the charger normally have lights on it? Do they light up when you plug it into the AC mains on the reel, or directly to the wall plug the reel was plugged into?

 

[dnmun]

if you can measure the battery voltage on the scooter charging port then the fuse on the scooter is not open.

if it did not blow the fuse in the scooter then it should charge.

can you measure the full voltage on the charger output?

Oh that would be ideal for sure.

Yes It has an LED 1 and LED 2. When you plug it into the moped only LED 1 turns red. When you apply power LED 2 goes red and then goes green once it's fully charged. When I connected it all up it just stayed on LED 1 and the fan didn't spin up.

The charger doesn't turn on unless it's connected to the moped I think? I don't recall if I tested the voltage on the charger it's self.. .I was too mad with myself for being daft. It's 7pm and dark here in England. The moped is locked up in my garage so I'll do these test tomorrow. Thanks again for your help.

The battery could have tripped the mains breaker....

Some chargers power themselves from the battery if not hooked up to the mains ( bad design.. but common ) this can be a disaster if you forget the charger plugged into the battery for an extended period of time without AC being supplied.

Then it probably isn't getting any power from the mains.

Check it on another AC plug on a diffferent circuit you know is working. Just plug the charger in, doesn't matter if it's on the moped or not--it should still light up an LED. If it doesn't, the input isn't getting any AC.

Plug something else like a lamp into the mains instead of the charger, if it doesn't work the mains is not working, try another plug somewhere else.

Yeah I can understand how that mistake could happen... then if the cells go below a certain voltage level they are dead?

Oh I can go and get my charger now and test it. brb.

 

[quackstar84]

Yes... lol it was the main fuse on the plug for the charger. The charger lights up now. No idea why I didn't think to check that. Very lucky this time that the fuse did it's job it time. Thank you everyone for your input. I don't think I would of check the fuse myself and fixed it.
