I found some physic/math formulas which allow me to calculate how much power and energy a vehicle needs to move at different speeds. As all of you know this depends on vehicle Cd and Frontal Area, so I actually have a quite large range of values. I'm looking for real data of different EVs at different speeds to compare to my simulation results: does it exist such kind of database around? And, most difficult, does it exist for motorbikes? (I wonder why motorbikes are so rare in vehicle mechanics literature!) I currently have this data for an electric minicar (400 kg) with Cd=0.3 and FA=2.2 m^2: Code: ``` km/h mph Wh/km Wh/mi W 10 6 23 37 230 20 12 25 40 509 30 19 30 48 887 36 22 33 53 1182 40 25 35 56 1414 50 31 43 69 2139 54 34 46 74 2495 60 37 52 83 3111 70 44 63 101 4381 80 50 75 120 5997 90 56 89 143 8010 100 62 105 168 10468 108 67 118 189 12789 110 69 122 196 13422 120 75 141 226 16920 130 81 162 260 21013 140 87 184 295 25749 150 94 208 333 31179``` This is for motorbike (Cd=0.7, FA=0.7) Code: ```km/h mph Wh/km Wh/mi W 10 6 23 37 228 20 12 25 40 492 30 19 28 45 830 36 22 30 48 1083 40 25 32 51 1278 50 31 37 59 1873 54 34 40 64 2161 60 37 44 71 2652 70 44 52 83 3652 80 50 61 98 4909 90 56 72 115 6460 100 62 83 133 8342 108 67 94 151 10111 110 69 96 154 10592 120 75 110 176 13246 130 81 126 202 16342 140 87 142 228 19915 150 94 160 256 24004``` W formula: E1=(C\$3+0,5*L\$2*L\$3*L\$4*I1*I1)*I1C3=Rolling Friction (= roll friction coefficient 0,015 * weight x 9,81) L2=Cd L3=FA L4=air density = 1,167 I1= speed in m/s Wh/km formula: D1=E1/J1J1 = speed in km/h If there are no mileage data around, it will be enough to have Cd and FA for vehicles (bot cars and bikes), I'll calculate mileage by above formulas. edit: Values for flat road, constant speed. update: added wh/km edit2: deleted "thousands dots" added mph column Last edited by jumpjack; 04-16-2013 at 03:53 AM..
