I don't know the bms used. Does it have a start / reset function? Are you now measuring a voltage U> 80v? On the battery? The votol can be damaged .... The standard wiring diagram provides for a precharge function

I made a very simpe precharge method. I have a contactor in the battery circuit, and i installed a paralel resistor (1kOhm) with the contactor poles. It can constantly keep the capacitors filled up when the contactor if switched off, and if anything happens the 1kOhm resistor limits the current. It works fine.

Hmm, that's 0.08 A.
What do you think of:
start process (5 sec, possibly automatic) battery - resistance 50 ohm - controller - then real connection between battery and controller !? Something like that, my ktm e freeride starts

Of course it should be good.
I just started to thinking on my car. I kept the original ignition switch, and the ACC position is fine to energize the main contactor, the IGN position controls a small relay, which connects the B+ and the E-lock wires for the votol controller. I can use the car as before, when it was diesel.
But if i want a 2 step prescarge process, i need a timer and a precharge relay.
And after i checked the consumption of the votol B+ without the e-lock, and it was nearly zero, the capacitors has a very low leakage.
This is why i think it is enough, it disconnects the controller from the battery, so i can prevent a fire or deep discharged battery. The resistor can keep the charging level of the controller capacitors, and i think for the capacitors it doesn't matter that are they full or empty.

Got my EM-100 controller and wiring kit. The throttle cable is way to short. Anyone find different throttles or thumb throttles that work with the controller?

Question :
When I connect battery to Volol EM150 there is a spark in B+ connector
Then the battery go to zero volt (protection?) when a disconnect the B+ from Votol the power is back
Does tis mean that the Votol is damaged? And wy is this happening
Please answer my question
Thanks
Ivo

A controller with empty capacitors needs to be charged. This is done via a current-limiting resistor.
Googling controller precharge.

The results will overwhelm you ...😉

You can make an extension with some black, red and green wire and the connectors needed which are in most connector sets which are very inexpensive.

Most throttle connectors wont work with the votol anyway. The throttle will be 3-pin and the Votol has 6-pin.

So with the correct 3-pin and 6-pin connectors you can make an extension.

What are the specs of the battery are you connecting? Whats the BMS rating? Seems like you are tripping the BMS when the inrush current charges the capacitors.

alles heeft de eerste gewerkt, maar na het afkoppelen van de batterij om deze definitief te installeren en het opnieuw aansluiten waser weer die vonk en toen viel de EM150 zonder spanning.
Ik heb er dan stroom opgezet met de oplader maar dat werkte ook niet.

can i preload with the 10Amp battery charger?
Or is this the same problem of spark?

40a battery for a 150a controller won’t do much except no load testing.

Yes, if you have a 72v power supply you can pre charge the capacitors and then connect the battery. This will let you keep testing with your tiny battery until you make the real battery which will need to be at least 72v 50ah to give 150a at 3C.

Once the capacitors are charged they will stay charged until you disconnect your battery (or the bms shuts off output) for a few minutes.

If your real battery also trips its 150a BMS i would be surprised.

dus ik start even ( 10 sec)op met de batterijlader, koppel af en schakel batterij definitief in.
Dit moet dan die vonk voorkomen dus.
Ik ga opstarten met een gloednieuwe Votol EM 150.
