Battery connector 2+4 pinout guess ECOOTER E2

[marce002]

Hello

Can anyone help me find pinout or at least what to expect to find in this connector, i mean in the 4 small wires not the + and - power ones, in this electric ECOOTER E2, battery is 64V20ah... the bms is connected to this connector of course and i wanted to know what information is shared between bms and the motorcycle....

thanks in advance

It's impossible to tell what protocol is used on what pins from photos alone. It's easy enough to figure out, though. Measure the AC and DC voltages roughly and see if any of them carry additional power lines. If they do, that's two pins. The rest will likely be some standard protocol, like I2C, CAN or LIN. Hook up an oscilloscope between the battery and the vehicle and look at what's happening on those lines, then post results.

yes thanks i will, did not do that because i have received dismantled bms, cells, case , connectors etc, so wanted to know if someone had experience with this ecooter battery, or if 2+4 is usually connected the same with other brands ... thks again
