Hi all! Maybe not the typical project here on ES, but I thought I should share anyway. Basically everything I've learnt about electric conversions is from this forum, so maybe someone reads something interesting in this thread
I already converted an 2wd basic ATV with a QS3000w motor and 20 LEV40 cells from an Mitshubishi Outlander PHEV. Figured we could use something a little more of a workhorse, and I already got lots of LEV4 cells left from the Outlander pack. So when a poor old 6x6 showed up in the classifieds I went and picked it up. It is a 93 Polaris Big Boss 6x6. I am not sure about how some of these ended up with diesel motors, because when I look up the VIN number the information about engine is missing. So I guess its some hack that is done after it left Polaris factory. It is maybe one of the worst motors I can think about putting in an ATV. 400cc single cylinder air cooled diesel with a whopping 10hp. Original motor was blown, so the previous owner had sourced another one and started to install it before he got tired of it and bought another ATV.
Worlds first and hopefully last.....
So the plan is:
- QS 3000w motor with Votol controller (72150 I think t was)
- Keep the transmission for high torque low speed performance
- 18S 2P LEV40 battery
- CA V3 for display and throttle adjustment
- Victron MPPT unit for charging 12V battery for winch and other accessories (thanks john61ct for the tip)
- Get it up and running ASAP and do all the little things and bugfixes before summer
I could not find an off-the-shelf sprocket for the gearbox bigger than 12T, and only for 520 chain. I would like it to be bigger because of the wear, but I will see hot it works. I also sourced a sprocet for 520 chain on the QS splines.... JFT1903. Went with a 14 tooth, which shud give me about 38kmh before field weakening in high gear (total gear ration from gearbox to wheel is 12:1 in hgh and 24:1 in low).
Not much progress yet, but I have removed the old diesel and instaled the QS.
I need to be able to tighten the chain, and was hoping to avoid idler sprockets. Hopefully this will be strong enough.
Some of the cells:
I have started with the battery boxes. I will divide them in two boxes. 9S 2p each. They will be located under the cargo bed. It is just enough space for the tires when it gets loaded up, but I have ordered 2" spacers for the rear wheels, so it will be plenty (I hope). I have kept the plastic containers for he cells, so they sit perfect isnide the metal box. Not the most energy dense cells, but they are powerful and easy to work with. And they seem to have a long life. I am using abut 35AH per cell on my other ATV, so this pack should be about 4.6kwh usable energy. The ATV will be used locally, so I think it will be enough. The cells can take quite fast charging, so I will get a fast charger if I end up using it a lot.
More to come soon!
