Question

Consider an electric vehicle with the specifications shown in tuhe eow The wadis fos can be expressod as 60 where ρ-1.2041 kg m-3 is the density of air, 1. Calculate the required power at the whools (W.) for the top seed o 1 2. Assume the overall transmission officiency to be 93%, what is re 190 K necessary orgne power for this vehicle? 3. Assume we need to go 100 km per charge at 100 kmh-1, and from eroereros,ーīnow that the car (using a 144 V battery system) vwill draw around 190 A at 100r capacity of batteries do we need while maintaining an extra 20% a arge ater teonw?
