It would be safer to use a electronic load, I have used a Tenma 72-13210 120V 300W to discharge batteries to a known voltage, it took quite a while at only 300W though. I think you could use that JK BMS with output and connect cell points so it will operate power transistors. Then connect a load li...

I am considering purchasing these same motors(or similar, also from Magelec). The seller on Ebay who I would buy from says that he will send a user manual and a CAN msg-list. If I do so I'll share here, but I am concerned at the lack of resources reagrding this company. I haven't seen any informati...

Is it necessary to assemble a pre-charging circuit before the inverter? Or can I just connect the wires and plug the power supply plug into the outlet? Precharge wiring contains DC contactor + DC relay + precharge resistor. As any HV assembly you need to test it in operation before you can rely on ...

Surely, it is no secret to many that in an ATX computer power supply there is 320 volts of DC voltage running on a large filter capacitor after the diode bridge. It is known that the diode bridge is not very powerful - only 6 amps. Now the question. Is it safe to use such a power supply to spin the...

Hi, i am installing Tesla Gen2 charger to my Mazda and i need to setup a disable circuit for VCU so that someone cant just drive off with charge cable connected :). I am looking at schematic for both connectors and i notice there are two additional pins which are ready as input and output but dont s...

So as the LFP packs are starting to be used in OEM EVs more widely wonder what chances do we have to use those in projects and conversions? Mainly it is difficult to determine how much charge they have left. What would be our options for BMS and SOC estimation? Would hacking the OEM BMS be a necess...

Paint It Black And Put It Back ! IMG_3504.JPG That looks really good! Hm... did you accoount for the movement of the loaded axle? It should have like 0.5cm movement in its loaded position. Just saying because i didnt think of that the first time and i had to shave the CV side down on the lathe!!!

Could it be that in map 3 the ramping is not used, so you could be getting quite big jumps in torque requests? I resolved this by going through values in the array. I made some jumps in values where throttle would be held, but RPMs increased. This resulted in values jumping up and down and then set...

this is queued up to how I hope to make it straight(ish) https://www.youtube.com/watch?v=NkQc7eshiXI&t=532s Now that is informative! Really shows theory and pactical application. Must see if you are extending some shafts. I just luve the NDT penetrant inspection. Some of the mechanics are shyin...

..... Anvil's are stupid expensive where I live, how about in your hood? Let me tell you something... even me, i shy from replacing the whole panel at the rear seats like you just did. Kudos! I simply took OBCs as far up as they would go and designed mounts from the underside. But i do have an anvi...

And expectation led me to belive i was going to see the actual use of that damn contraption together with a chapter of english wheel and tap hammer application . Well done.

My daughter asked me if i could mount a rear camera to Mazda. I thought what to use best and i decided to buy a radio with 3.2in LCD display. That display has a connection to plug in vide input from camera. Screenshot_20240320-115503_AliExpress.jpg I bought a small 8 LED camera and mounted it above ...

I am now trying to install 3phase Tesla Gen2 charger despite the fact that the last 12S battery module occupies its space under the rear seats now. I asked my friend to cut and weld me a flat mount where Tesla charger will fit behind the rear seats in the trunk area. I will use rear seat belt bolts ...

Thanks arber, that reply hits every single one of my questions! Perhaps a more obvious one. My canbus network is terminated by a Zombieverter on one end and an IVT shunt on the other (it has an internal resistor). Am I correct in assuming I can connect these chargers (plus my outlander heater and A...

Yes... i think your idea is doable.

Hello, ...... 1. I was wondering if anyone had instructions on how to wire them in 3 phase configuration?

Question 2: I have made a really good pedal map setup for me i think. The only thing i am bothered with is fast torque transition when i am already rolling, maybe between 250rpm and 500rpm. There is a weird shaking there but then it becomes smooth as i go through the rpm. What would that be? Are th...

Hmm, no. The only thing I know about the encoder is that it's a superseal connector that goes into the far side of the motor. ...... Nothing in the spec sheet identifies the encoder other than its pinout. https://www.dynapar.com/technology/encoder_basics/quadrature_encoder/ Ok, then your best bet w...

Hi. I've now experienced this twice in a short time. The DC/DC turns off during driving, resulting in no charging of 12V battery and me loosing steering servo and heating in cabin. Any ideas what can cause this? Unfortunately I don't have any loggs or error messages. The DC/DC output seems to be ar...

Thank you for explanation. Question 1: Would tpsbins[21] mean pedal position from 0 to 3% and then 3% to 5%? Is your intention in the lower part of the throttle to be really accurate with pedal position? So if i would change your pedal map to... const int tpsbins[21] = {0, 5, 10, 12, 14, 20, 24, 28,...
