Can You Pick Out The EV?
Can you pick out the EV? Wait- they're all EVs! Well, after about 5 months of trying to get a spot, there I am smack in the middle charging away. Today was the last bit of rearranging needed to squeeze me in, but now that's over, just in time for the semester to start tomorrow.
The school year started today for the public schools, which is good for me. All my high speeds hills that I have left to contend with are now 20 MPH school zone, which means good EV driving for me. The arrival of my new Synkromotive controller is still up in the air, but I really hope its soon. When I do get it, I am going to start off with the motor AMPs @ 500 and the battery AMPs @ 200 to save on battery power. According to the calculator I should need anymore than 175 battery AMPs to climb these hills, and anything higher is just wasted AMPs.
I also decided to do the math savings. It costs $2.86 a day to drive my ICE to school and back, which ends up being $57.37 a month at current gas prices of $2.70 a gallon. Now my EV takes 6.5 hours to charge, and at the 7.5 cents/KWh that is $0.49 a charge up, or $9.80 a month in electricity. The $0.075 is the cost of electricity at night, when I charge my EV. So it's basically a 6x savings in costs!
Now the trick is figuring out how long I can drive it before weather become a range limiting factor. BTW, it was 48 F when I left this morning and now its 86F where my EV is parked. This New England weather is just screwed up.
