    So I’m relatively new in karting and still in high school. One of my classes is a year long engineering project and I was wondering what the karting community thought of electric karts? Other than commercial entertainment use I haven’t seen anything about it and I believe there are definitely some advantages to trying it. Off the top of my head, there’s less noise for people to complain about and no need to worry about mixing gas, messing with carburetors and clutches (in my yamaha class for the clutches at least). What’s the general opinion on them though? I could see it being almost similar to a TaG engine in terms of power but I’m not really sure. It’d be a fun design concept at the very least if nobody has executed it before.

    Hi Aaron,

    Check out the Sanzaru Games Karting Championship as they have been running a competition class utilizing electric motors for the past few years. See if you can connect with their director and maybe he can connect you with some of their drivers.

    Someone brought one out to our track once and ran with the Tag class.  He used the motor and batteries from the Zero Cycle.  The top speed was about equal, maybe a little faster, but where he excelled was in acceleration (of course).  Normally on our back straight you might be able to pass one other kart, he was able to take 3 of us in the first half of the straightaway.  The one problem that he has running with us was heat production.  The batteries produced so much heat when charging between heats.  He had bags of ice on the batteries and motor in between runs to cool them down.  He actually missed one heat since the batteries weren’t charged and were still hot.

    Thanks, could you tell me how long his batteries lasted? I think it’d be really cool to have a dedicated conversion kit to get an electric kart. Or if they do I’d like to hear about it because I’ve been looking but I can only find homemade setups

    You’ll find rental kart setups, and home-made setups.  that’s basically all there is out there right now.

    The best option for racing would be to have a decent thermal management system, in addition to a spare battery pack or two.

     

    Battery life will greatly depend on the track, and % of time spent on the throttle.

     

    The Zero motorcycle ran an 11.4kWh battery and I would guess that you could get 10-15min out of it. They ran one – in production trim – up Pike’s Peak in about 12 minutes.

    Check out Rattlesnake Racing in California. They are at the forefront of electric karts. They have run several NCK road races and are fast.

    Mixing gas, noise and smoke are the charm of kart racing.

    Wait until you have a lippo explosion that burns someone in half.

    Electric Karts are the way to go . I currently have one Ive been running for 2 years. 67 hp 104 lbs torque   its fun    still working out the bugs. Contact Harlan at hollywood electrics   he can set you up with the Zero motorcycle running gear, it seems the easiest way to go. Im currently working on a twin motor electric, plan on setting some track records.I also race a 125 shifter kart it tries to kill you the , electric is so smooth and depending on the track we compete with either the TAGS or the shifters. Working through heat  , charging and weight issues. Ive been in karting over 40 years, in a couple of years every track will have an electric class. No noise, minimal maintenance and faster than gas.  Every year they make big improvements.

    Looking at pictures of the zero motor and it appears to be similar to what our electric group runs out here.

    To be honest I know zip about electric karts. What kind of battery do they use and what does it cost? lithium-ion probably.

    You can use whatever battery you want.  Li-Ion is the current best performer (of non-experimental batteries) with respect to energy per unit mass.

    Depending how motivated you are, you could use modules from existing vehicles – Zero motorcycle, or a number of electric cars.  Or, you could make your own cells to fit neatly on the kart – E-bike folks have documented it fairly well:  https://www.electricbike.com/home-built-battery-18650s/

    What’s the buy in to retro fit a gas kart with electric including charger, extra battery ect? has anyone put together a package?

    Thanks,

    if you were to go with commercially-available pre-made “kits” you’re looking at $3-7k depending on power and air vs. water cooled setups.  The fancy water-cooled setups with regenerative braking make 15kW (20hp) “continuous”, and 38kW (50hp) “peak” (1 min continuous).

    Check with Hollywood Electric Motorcycles , Harlan can get you a quote, The s motor has 67hp and 106 lbs of torque, they work well on sprint karts. you can run them hard. I always start with a shifter kart frame , not alot of modification needed. Takes a little while to cut down the wiring harness but other wise . You just need to fabricate a motor mount and battery box.
