1. If a battery temperature was initially at 30 C during driving. Calculate the hourly average battery temperature if the car was stopped and parked at an average temperature of 40 C for a duration of 5 hours? Assume that the battery has a uniform temperature. The battery average thermal conductivity is 0.8 W/(m.K), battery specific heat is 1000 J/(Kg. K), battery density is 2 grams/Cm3. Assume the battery has a mass of 540 Kg (Tesla Model S). Battery surface area is 2 M2 and the average heat transfer coefficient is 20 W/(m2.K), Repeat with an average heat transfer coefficient of 40 W/(m2.K)Please use Excel sheet to do the calculations and generate the curves for the average battery temperature vs time. 2. Repeat the above calculations if the car was stopped and parked at 12 Noon for 48 hours on a hot summer day in each of the following cities: Phoenix, Arizona; Kuwait City, Kuwait; Ahmadabad, India. You need to select one of the hottest days in each of these cities and report hourly temperatures for 48 hours.

Transcribed Image Text:1. If a battery temperature was initially at 30 C during
driving. Calculate the hourly average battery
temperature if the car was stopped and parked at an
average temperature of 40 C for a duration of 5 hours?
Assume that the battery has a uniform temperature. The
battery average thermal conductivity is 0.8 W/(m.K),
battery specific heat is 1000 J/(Kg. K), battery density is
2 grams/Cm3. Assume the battery has a mass of 540
Kg (Tesla Model S). Battery surface area is 2 M2 and
the average heat transfer coefficient is 20 W/(m2.K),
Repeat with an average heat transfer coefficient of 40
W/(m2.K)Please use Excel sheet to do the calculations
and generate the curves for the average battery
temperature vs time.
2. Repeat the above calculations if the car was stopped
and parked at 12 Noon for 48 hours on a hot summer
day in each of the following cities: Phoenix, Arizona;
Kuwait City, Kuwait; Ahmadabad, India. You need to
select one of the hottest days in each of these cities and
report hourly temperatures for 48 hours.
