How does the use of a manual transmission in an EV differ from an ICEV?
Several, mostly minor, ways:How does the use of a manual transmission in an EV differ from an ICEV?
ICEs have a minimum RPM speed of 700-1000RPM, and a "Power band" of 3000-5500RPM (typically).Are manual transmissions, especially say a 5-speed with overdrive, not as advantageous in an EV? I don't have a feel for the different parameters like batteries, motors, and such, but I'd think that something in the EV system could be smaller by taking advantage of a transmission.
It took sometime for me to learn that skill but still not too confident....think of double clutching an ICE, not to difficult but, you will need to learn the new driving skill to avoid damaging the used manual transmission. good luck
I think I'm using about the same transaxle in the buggy. Upshifts are with less than 1 second delay, backing down the gears would take about 2 seconds each if I didn't blip the throttle. Since I really only need to shift up once for freeway speeds it's no big deal, even though I'm 2 traffic lights away from 3 freeway onramps.By the way, my Ghia shifted like crap clutchless and the transmission shifted smooth as silk with it. The transmission was designed to use one. That is not a personal preference. It's a fact.
It certainly does! When you push the clutch in on your car (gas or electric) you disconnect the motor, flywheel, and pressure plate from the transmission. This leaves a free spinning clutch disc, input shaft, and some gears for the syncros to speed match in order to drop into the next gear. On an EV without a clutch the syncros have to match speed to the coupler and motor armature, which are free wheeling in place of the clutch disc. It certainly weighs a lot more, but the the diameter should be smaller. The inertia to overcome is based on mass and velocity. Something 2.5 inches from the center of rotation is moving slower than something 4 inches away. If you try to shift clutchless while retaining the flywheel and pressure plate it will be a lot harder with all the added fast moving mass. Smaller motors and smaller and lighter shaft couplers should also make clutchless shifting easier.Maybe having a solid shaft connected to the transmission makes a difference vs trying to learn clutchless shifting with the clutch in the car. But even so I'd rather have what the factory intended the transmission to have.
