New Top speedNew speed record, 105 MPH! Top speed was tested on flat ground in 5th gear. Current from the battery was 216 amps. |
Dyno Result: 83.5 hp

Top speed: 98.6 mphNew speed record, 98.6 MPH! The car was still accelerating, it will easily break 100 MPH on flat ground now. The 90hp TDI Passat has a top speed of 112mph, my new goal is to beat it! |
280 Amps @ 280 VoltsI installed an Ammeter to measure battery current. I can peg the gauge at +300 Amps, but for reliable daily driving, I usually limit current to 260A. I can also peg the gauge at -100 Amps. Based on the 83.5 Hp reading at the wheel, and the 105 Hp (280A x 280V), my overall efficiency is around 80%. |
Here is a comparison of my Siemens motor vs. other EV motors. The data in the graphs were taken from manufacturers specifications. As you can see, the Siemens motor has the highest hp value, and has the most area under the curve. |
Recharge speed: 14 miles per hourThe inverter and battery performace has been very consistent. A 25 mile trip to work brings the battery from 328V to 308V (about 12.3 volts per cell). I typically recharge using 10 amps for 3h 20min at 230 volts. I can charge twice as fast at 20 amps which equates to about 14 miles per hour (hour of charging). |

From my calculations, 0-50mph should take 13 seconds. I am actually doing it in 10.5 seconds, so I beat my goal, and also beat the Ford Ranger EV (11.6 seconds)!
The Ford Ranger EV effeciency is rated 356Wh/mile @ 60mph, 237Wh/mile @45mph. |
