Hello I am working on my post graduation project related to conversion of Toyota Yaris(sedan)
What type of AC motor should I use in order to attain a maximum speed of 120kmph?
What type of battery pack should I use in order to obtain a range of 120kms or more?
Please help me with relevant calculations to support your answer
I have a 1200kg Mazda which goes 150km/h on a 30kW air cooled motor even 160km/h max is not a problem. BUT at that speed motor sinks cca 70kW. I am not sure how much it gives in Pm exactly, but wattmeter says 70kW.
What are you postgrad off? You can easily calculate needed power for level drive at certain speed. All the formulas are known. I bet there is a Cd for Yaris online as well as Ctr for tyres.
You can make a spreadsheet that calculates your power and range at certain speeds. I made one and i even put in GPS points at 1s intervals to get energy required for trip and calculate range. I could not make regen calculation work though

. I just ignored it then.
What i did in the end was calculate all resistance for level drive and multiplied by 1.2 due to transmission and bearing losses. When i wanted power on a hill i just took the largest slope i will most likely be driving on and calculated hill force and added that to get P required.
The precision of calculation was scary!
It seems to manage largest highway hill my car requires 40kW of constant power. Thermal management of air cooled ACIM is well within that at least for 10 minutes.
I wish for a water cooled motor though. That would mean longer time under high power for those extended trips to the sea

.
I imagine you would need 20kWh to reach 120km. Maybe Leaf pack? Since it is a light car you could get away with Volt pack for 100km range!
I have seen Smart EV top 120km with 16kWh but at speeds under 80km/h not more!
