Project 1 Mechanical design of battery pack

 Prepare a detailed battery pack drawing along with its enclosure. State your assumptions Battery pack capacity: 18 kWh Cell: ANR26650M1-B    Cell Description           Calculation Nominal Voltage of a cell= 3.3V Nominal Capacity of a cell= 2.5Ah Cell Energy Capacity is the…

Electric vehicles use large batteries to store energy. The energy flowing into the battery pack as it is charged either from regenerative braking or from the grid and discharged from the pack to power the vehicle and its accessories is measured by electrical current and voltage. The flow of current causes heating in the…

How weakest cell limits the usable capacity of the battery pack? What is the solution?  Li‐ion batteries are influenced by numerous features such as over‐voltage, under-voltage, overcharge and discharge current, thermal runaway, and cell voltage imbalance. One of the most significant factors is cell imbalance which…

State of Charge The state of charge (SOC) of a cell denotes the capacity that is currently available as a function of the rated capacity. The value of the SOC varies between 0% and 100%. If the SOC is 100%, then the cell is said to be fully charged, whereas a SOC of 0% indicates that the cell is completely discharged.…

Make a MATLAB model of fuel cell-powered electric vehicle and comment on results A fuel cell is a device that generates electricity by a chemical reaction. Every fuel cell has two electrodes called, respectively, the anode and cathode. The reactions that produce electricity take place at the electrodes. Every fuel cell…

Q.) Simulate generic battery model charge-discharge using UDDS data. A driving cycle is a series of data points representing the speed of a vehicle versus time. Driving cycles are produced by different countries and organizations to assess the performance of vehicles in various ways, as for example fuel consumption and…

Q.)Prepare a table which includes materials & chemical reactions occurring at the anode and cathode of LCO, LMO, NCA, NMC, LFP and LTO type of lithium ion cells. Li-ion Batteries A lithium-ion battery or Li-ion battery is a type of rechargeable battery. Lithium-ion batteries are commonly used for portable electronics…

1.For a defined driving cycle, calculate the energy required for braking. A driving cycle is a series of data points representing the speed of a vehicle versus time. Driving cycles are produced by different countries and organizations to assess the performance of vehicles in various ways, as for instance…

1. Run MATLAB demo ‘Speed control of a DC motor using BJT H-bridge’. Modify the model such that the armature current doesn’t shoot up when the motor changes direction from forward to reverse.   Major blocks used 1. IGBT The Bipolar Junction Transistor (BJT) when used for power switching…

1. Which types of power converter circuits are employed in an electric and hybrid electric vehicle?    In Electric and  Hybrid Electric vehicles we use three types of power converter circuits i)AC to DC converter (Rectifier) A power electronics circuit that converts alternating current (AC)…

1. What is the difference between the mapped and dynamic model of engine, motor, and generator? How can you change the model type?  Mapped Model The Mapped model for any element (Engine, motor, generator, or any other) is made up of Lookup Tables. The specified data can be entered if the parameters of the system if…

1.For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations.   Step1: After opening the ADVISOR tool, Change the "Load File" as 'EV_degaults_in' and also change the 'Cargo mass' into '500'. Click on the 'Continue'…
