Re: Battery packs with 3p

the 2p/3P is irrelevant..... its dependant on the rating form the manufacturer or how far your willing to push them (tesla push the original 1860's way beyond Panasonic spec)... I would worry on more practical things like what will fit.. will i be overweight... where can i fit my motor?

Re: DIY Economiser for OEM Contactors

I haven't played with the voltage method however on the bench I have been playing on the bench with the resistor value to get the duty cycle down and increasing the full on time to reduce contactor bounce when at very low battery voltages (10v for terminally flatt 12v battery)...

Re: Outlander VCU - Rear inverter, Charger and BMS

Am I understanding this thread correct you are able to command 280Nm from the stock inverter? I assume that means that you are exceeding the stock 60kw power output? Or is it just hitting 60kw at lower rpm? (I assume current is recorded from the shunt?)

I would, keep things simple and not bother with degregagtion calculation all you really want is soc calculation based on resting voltage and have a fall back where ah are used when voltage isn't possible e.g. motorway drive. a variable for battery ah is all that is needed and as we can record ah use...

Re: Replacing the VW BMU aka implementing high level BMS functions

You really going to go all out with 4.2v/cell seems quite a bit more than the 4.1v we are used to but I guess if the OEM does it it's probably ok :? Not sure I would want to push it that far daily.

Re: L210 gearbox

To my understanding is that field weakening is effectively like making the motor act like a generator to make more voltage... However this is very difficult to control and a very bad idea in a generator (you only have to look at some of the oi simulator stuff to realise what weird thing it is). I th...

Re: L210 gearbox

We are deffo getting a 1+1=5 with the voltages here... The reason for the boost inverter is basically so the motor doesn't do field weakening, particularly the generator. Based on the numbers so far you boost to 600v and you still have to field weakening to get it to 14k rpm top speed of the cars. W...
