Re: Volvo V60 ERAD Electric Rear Axle Differential + Inverter

ERAD weight is around 48Kg (including cables & oil). I haven't driven a V60 PHEV yet, but have been told that it will reach in Pure (electric only) mode about 120-130km/h. Meanwhile I had the chance to make logfiles of both CAN-busses in a running V60 and did build up some communication with the...

Sure, or course. Will check one of these days if the V7 is released yet, else just start from the V6.

Re: Arduino Due CAN stops sending

I don't have experience with the DUE, but just with the Teensy's so the info below may not be applicable for you; Are you using the 'millis()' or 'micros()' command for creating timers/delays ? If yes, be aware that the returned value runs over. That has to be taken into account in your code. Had si...

Re: GM / Chevrolet Volt Gen2 DC-DC converter

Did you connect 12V battery or just the load? Yes I connected a small battery on the output. That might probably be needed to let it start. I can't remember the PWM frequency, but I used the same as on the output (which you can measure). Given the fact that the charger uses 100Hz, I guess the DCDC ...

Re: i3 controller hacking from diyelectriccar.com

The REME (small 25kW REX inverter) could be a nice option for small cars & motorcycle conversions. Looking at the video, it has a quite basic controlPCB with no weird connectors and an easy interfaceable IGBT-driver board without SPI (https://www.infineon.com/cms/en/product/power/gate-driver-ics...

Re: Charging from a generator ?

The Leaf batteries are not the best cooled batteries, and you will certainly generate a lot of heat in them while racing, subsequently fast charging and racing again. Would it be an option to make two batteryboxes and a smart solution to easily swap them ?
