Charger problem

[Henkav]

Hi,

With some help from Tom I measured the battery Voltages and they were all to low.
So I wanted to charge the battery and found out that there was no difference in Voltages at the cells.
So I did measure the charger and found out that I only had about 6 to 7 volt output.
So far not much fun with my E-bike kit witch I bought 3 weeks ago.

And yeh, my wheel is as round as an egg, like manny other wheels I guess.

What I was thinking about is, did the charger broke down because of the failure of the battery yesterday or is it just bad luck.

Maybe "first" test the battery at the charger points to see if there is a voltage there for the charger to work. No need to push probes in all the way just get the voltage and its polarity orientation.

If there is no voltage then test the resistance to find if there maybe a short circuit.  There will be 0 volts and 0 resistance or the polarity is reversed to the charger plug if the battery charging circuit is causing the charger to fail.  Wise to check these things before putting another battery charger on there.


What did the voltage test on your pack, And what pack did you buy?]

When you get a new charger test the charger plug to see if its the same polarity as the battery charger port.

Hi,
I did measure the charger without connection to the battery.
I got 6 Volt out of it.
The battery measurement of the B 1 to 10 points I mailt it to you this morning.
Here are the measurements again:

I opened the Battery and measured the next Voltages:

B   negative side
B1 yellow wire(the second wire)    3.3 V
B2 yellow wire(the third wire)       6,6 V
B3 yellow wire(the fourth wire)     9,9 V
B4 yellow wire(the fifth wire)       13,2 V
B5 yellow wire(the sixth wire)      16,5 V
B6 yellow wire(the seventh wire)  19,8 V
B7 yellow wire(the eighth wire)     23,1 V
B8 yellow wire(the ninth wire)       26,5 V
B9  black wire (the tenth wire)      29,8V
B10                                          33,2 V

So everything is a bit low I believe.
And these measurment are with nothing connected to the battery.

I've got everything from GoldenMotor
Its a 36 Volt 12 AH set.

Hi again.

Lookng good and balanced on the BMS ok, needs a good charge and balance charge.  Leave it on the new charger for a long time..  Its ok to let the battery live on the charger.

Do you get any volts out of the socket on the battery where the charger plug into  in the actual charger socket it needs to be tested to say that it is not the problem.  The charger socket may be soldered wrong in the battery causing the charger to fail.

Thank you.

Hi,

"Leave it on the new charger for a long time..  Its ok to let the battery live on the charger."
At this moment I do not have an extra charger.
So this is not an option for this moment.

"Do you get any volts out of the socket on the battery where the charger plug into  in the actual charger socket it needs to be tested to say that it is not the problem.  The charger socket may be soldered wrong in the battery causing the charger to fail."

The voltage is 32 Volt. Its the same as the output of the battery.
The socker is soldered correct. The "+" is the middle point of the socket.

Thats good so if and when you get a new charger you will sure to test its polarity, and from our understanding a good charger should work on your battery,

[Henkav]

Thanx Tom for youre help.
Do Goldenmotor has some kind of warranty system.
Or do I have to buy a new Charger by myself.
And what if the new charger will go defect again because of the battery.
I still believe that the battery is working correctly.
Because I had 2 led light on while the Magic Pie didn't rotate anymore.

Hello!

I am not TOM,

I am Les

You need to contact TOM at zhourenli@goldenmotor.com and do some tests with him.  Maybe show a link to this thread where he can see you have done some tests already.

Make the email short, detailed and to the point, Send order details, name and address, some basic proof of purchase.
   
Avoid the life stories how you drank coffee when this happened and how fast your bike goes and what not.

Stay right on the mark with your Email. TOMS English isnt good so use common used words..

GM are extremely busy wit some huge orders to be shipped ATM.  I think GM should send you a new charger as long as you didn't damage it yourself. You may have to be a little patient.

While you wait it maybe a good idea to find a way to get a few volts in the pack.

Please unplug your pack from the controller and do not use any more capacity until you get some volts into it.

   

[Henkav]

Thanx Les for all youre help.
Sorry I colled you Tom.

I did send Tom an E-Mail, so I'll wait.

Today I got myself a new 36 Volt charger. (not from GM)
It was OK before I connected it. (I measured the voltage)
And as soon I connected it to the battery it went broke.
So now I've got 2 defect charger because of the Goldenmotor battery.
I defenetly believe that my LIFO4 battery is defect.

Whats next to do?

Good news,
 
I did repair my 2e charger and I could load the battery and its looks like it is working OK now.
Today I did ride the bike for 17 KM without any problem.
The only problem left is the Charger I got from Goldenmotor.
That one is defently defect.
 
Thanx all for you're help

Greatings Henk

enjoy!

I did repair my 2e charger

Interesting, I am intrigued. What did you find was wrong with the charger and how did you fix it? I seem to be getting something from my charger but having read about the so called battery condition indicators (LED's on the throttle) I am about to buy an analyser. My prospective 'e-bike dashboard' on the mental drawing board is starting to look l aircraft instrument array. It seems so many others have been here and done just that with monitors for every conceivable possibility....has anyone seen an e-bike cappuccino machine (36 volt of course)?

[Henkav]

I mailed Tom for asking for a new charger because the Goldenmotor charger was defect.
So far nothing from GM.
I don't know if GM has some kind of warranty for people who buy there stuff.
So if you thinking about buying things from GM, go to a GM dealer and not from the internetsite.
So when you've got problems, you can go to the dealer in youre own country.
