So I am using a golden motor controller. i am not sure if it is doing a soft start, if it is, id love to see that changed up and if you all have ideas where in the software to disable that id love that as well.
So i attempted a 5 to 1 gear ratio which gave me exciting acceleration and torque, potentially breaking the gear box if not careful. but netted a very very low speed of 18mph. and used very few amps. i tried a 2:1 ratio using an 18 tooth to 31 tooth and it got me around 41 mph, but god awful acceleration.. im using now a 14 to 31 tooth and so far its a nice balance of top speed of which ive hit 44-50 mph depending on the grade of the road and we have quite a hilly area that i live in. i think im going to settle on a 12 to 31 tooth system that should get me around 40 mph top speed and better taker off acceleration, and im hoping it doesnt draw so many amps? its odd because when i had a large sprocket it never really hit over 220 amps. same with a super high gear ration of 5:1 but my current setup will easily do over 300 amps sometimes. which confuses me
what gear ratio are you suggesting fechter?
haha INWO buddy yes! sorry it took so long to reply. i ADORE my BMS system, thanks to you! yes i am totally in for it as it would clean up my batteries and make things safer i believe. so lets do it, for a total of 4 batteries! by batteries are pretty much setup as a square just bare in mind i will in the future set them up for 96 volts, but leave them in 48v form for the bms and charging, that should be ok correct?
Galderdi, you are the only person to notice what i did there. of course i did that! i went in and bought water! im thinking the savings will be insane already from my 13 mile per gallon jeep commander and even my 22 mpg Chrysler crossfire.
im going to calculate my WHrs usage, i think i calculated a usage of 7.5 ah per mile which is ALOT, if i can get it closer to 5 i will be sitting really pretty!
i did actrually install a motor cooling system today i want to get that motor nice and cool , i may add a heat sink to the front since it may get warm in our arizona summers . weight of the cooling system was like 4 pounds
voltage seems to be my only way to increase speed and efficiency
tomorrow project will be to wire in my solar panels which should get me an extra 5 amps into the battery while driving and while parked which will be helpful, and thge panels weigh like 6 pounds
the clutch i cant figure out...we tried a cvt which just collossaly failed and was loud as hell... second motor may not be a terrible idea. i have a 5kw motor laying around i may sell with controller
update for today. i drove it for a 15 mile round trip and it did great minus the take offs. the cool part was i had around 50% maybe 60 % battery left meaning a theoretical 30 mile range? i was very excited. it was only ever bogged down at one point on one large hill, it was down to about 30 mph up the hill with a speed limit of 35 so some people weren't happy behind me but i was fine . all with my stereo and subwoofer blaring
this project is exciting and im hoping that a second rider wont kill my power.... all ideas are welcome!
