Question: Battery pack capacity: 18 kWh Cell: ANR26650M1-B. Prepare a detailed battery pack drawing along with its enclosure. State your assumptions.   Solution: Lithium Werks’ 26650 cells are capable of delivering very high power due to its use of patented Nanophosphate ® battery technology. Based on lithium…

Question 1: Simulate the 3 test cases from harness dashboard and write a detailed report on the results. Solution 1:   Test Sequence 1 Result: In test sequence 1 there are different states: Driving: During time period of 0 to 3000 sec driving condition is selected which means battery is been discharge. As a result…

Lithium ion Batteries   It was not until the early 1970s that the first non-rechargeable lithium batteries became commercially available. Attempts to develop rechargeable lithium batteries followed in the 1980s but the endeavor failed because of instabilities in the metallic lithium used as anode material. Lithium…

Question 1: Search and list out the total weight of various types of aircrafts? Solution 1: Basic Empty Weight (BEW) is the weight of the aircraft "as built" and includes the weight of the structure, power plant, furnishings, installations, systems and other equipment that are considered an integral part of an aircraft…

Question 1: For a defined driving cycle, calculate the energy required for braking. Solution 1: Drive cycle date shown in excel sheet is of UDDS drive cycle. Formula used to calculate drive cycle is given below: `E=((1/2*m*v^2)/1000)` Another random drive cycle is taken and energy is calculated with respect the drive cycle.…

Question 1: Run MATLAB demo ‘Speed control of a DC motor using BJT H-bridge’. Modify the model such that armature current doesn’t shoot up when motor changes direction from forward to reverse.  Solution 1: In the given model the speed of motor is controlled using BJT H-bridge. The Bipolar Junction Transistor (BJT) when…

Question 1: Which types of power converter circuits are employed in electric and hybrid electric vehicle?    Solution 1: There different types of power converter used in EV and HEV: AC to DC converter: A rectifier is a device that converts an oscillating two-directional alternating current (AC) into a single-directional…

Question 1: What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Solution: Mapped model: Model uses a set of steady state lookup tables to characterize performance or represents macro engine behaviors as a set to lookup tables. The tables provide overall…
