Onboard Charger Replacement
« on: June 06, 2021, 04:02:11 PM »
Hi
A few days ago my onboard charger died. (Zero S 2014, 11,4kw battery)
I still can charge my zero with my deltaQ Quick Charger.

Now i am looking for options on how to replace the OEM Charger.
I was looking on aliexpress and found this charger:
https://de.aliexpress.com/item/1005002519693895.html
Seller says the charger can be programmed to 116V 11A. I plan to use two of this chargers in parallel - so i can still charge at a free bike station near my home which offers only 1300W, 230V (using one charger then).

Can i connect the charger directly to the battery terminal?
When there is a problem with charging (bad cell,...) will the BMS still stop the charge then?

As far as i found out i can connect the charge enable and charger attached signal on PIN 11,12 and 13(GND) of the original charger plug - i would not have to do that when i connect the chargers directly to the therminal right?

thanks for your help!

The latest version of the on-board charger seems to be an improvement over the ones installed in the 2014 bikes. They sell for $800 and are relatively easy to install, with only three electrical connections. No instructions are needed and they will work without any hassle. So you might want to consider going that route.  Attached is a photo of the latest version of the OBC.

Thanks for the info, i will ask my zero dealer... Hopefully the price in austria is similar...

Also i am not sure if it will fit - because the connector on my charger has only 3 wires and on a different thread here the same connector had many more wires...
But i still consider any other option, maybe someone has useful tips about that too :)
