Re: Interfacing: model 3 PCS <--> aem EV BMS-18 master

The AEM BMS only needs to see the CP and PP pins if the VCU is directly controlling the OBC. If not they can be left disconnected.

Re: Charging in subzero

Modern OEM vehicles will condition the batteries before allowing them to charge when it gets really cold. This may take the form of heating the batteries while charging at a very low rate and increasing the charge rate as the pack temp increases, or in extreme cases it may practically withhold charg...

Re: We will no longer be able to hide subscribers count on YouTube

I read somewhere that it was to crack down on the spam/clone accounts that try to steal a popular channels identity to pull scams.

Re: Tesla Large Drive Unit Max Voltage

The LDU inverters DC-Link caps are only are rated for 450V so anything above that will be at your own peril.

Re: Tesla subframe: same for SDU and LDU?

I think it would be really involved to reduce the track width of the tesla subframe/suspension. Doing it would involve completely redesigning and fabricating the suspension and getting the geometry right would be a huge challenge.

Re: Partlist for a Tesla Swap Project

Don't underestimate the role of the batteries in the ultimate power the system makes. The delivered power is almost always limited by the current the batteries can supply at a given voltage rather than the motor itself. The P85 vs P100 you mentioned is a great example since the motor in both is iden...

Re: 9th Generation HAH Inverter

the DBC file should have a ton of info in it. Have you dug into it or are you committed to changing out the OEM control board?

I am interested in hybridizing a race car. Adding an extra ~100hp and using regen to charge it back up again every lap sounds real interesting.
