ECE 1301 - Modern Electronics Technology Spring 2022 Homework Assignment \# 4B (Battery Capacity) Everyone recognizes that battery is the most important and challenging component of an Electric Vehicle (EV) because it determines the crucial factors such as the range, how much the vehicle is going to cost, safety, convenience of recharging the vehicle. There are many types of batteries found in the construction of today's Electric Vehicles, such as Lithium Ion (Li-Ion), Molten Salt (Na-NiCl2), Nickel Metal Hydride (Ni-MH) and Lithium Sulphur (Li-S). In this assignment, you will conduct a comparison between Lithium ion ( Li-ion) and Ni-MH batteries in terms of capacity, life span, weight, and cost. Use Tesla Model 3 and Toyota Prius as two car manufacturing examples in your study. Provide a recommendation on which battery type will be the best option for the next geeration of battery solution in Electric Vehicle. Use below specifications tables as a guide on your study. Tesla 3 Specifications Battery i. Specifications and features of tig I echarpesbie baffery flat powers mis vericie. Manufacturer The name of the comeany that has manufactured the Tesia and Panasonic battery. Model NCR21700A The model name of the inchargeable battery. Type of rechargeable battery The bpe of recharpeable battery depending on fts Lithium-on composition. Battery capacity The capacity of the rechargeable batter that powers this 54kWh (kilowatt hours) EV as specined by the manufacturet in kilowatt hours.
