There are 2 requirements are designed in two subsystem- Requirement…

Simulink Model- Circuit construction and working: In this ckt we use li-ion cell 1 to 10, temperature sensors, ambient temp block, state of charge estimation, scope, charge discharge profile given to ckt, from and goto block. Results: 1) Results at 300 k i.e 26.85 degree celcius 2) Results at 310k i.e 36.85 degree celsius…

To make the battery pack we have to first finalize the nominal voltage and capacity of the pack. Either it will be in terms of volt, mAh/Ah or Wh. The individual cell : ANR26650M1-B has Nominal voltage = 3.3 V Current capacity = 2.5 Ah So, let us assume that for 18 kwh battery pack we need supply voltage of 200 V and 90Ah.…

Simulation of closed-loop BMS- The BMS model consist of a BMS ECU (electrical control unit) and a plant. The control unit with its various monitoring  and control algorithms is connected to a block with the representation of the battery pack and associated circuitry and peripherals.   The harness dashboard is…

ANS 1 1. Search and list out the total weight of various types of aircrafts.  Weight is a major factor in airplane construction and operation, and it demands respect from all pilots and particular diligence by all maintenance personnel.Excessive weight reduces the efficiency of an aircraft and the available safety…

ANS 1 We require some amount of power which is used for accelerating the vehicle and also for the braking of vehicle. Here we consider the drive cycle which is predefined . Workdone = kinetic energy = 0.5 * m *v^2 For calculating the energy- E =0.5*m*v^2 m = mass of the vehicle = 1000 kg v = velocity of the vehicle = Vf…

ANS 1 The bipolar junction transmitor(BJT) when used for power switching applications, operates as an IGBT.Where it is conducting(BJT operating in the saturated region), a forward voltage vf is developed between collector and emitter. Therefore the IGBT block can be used to model the BJT device. The IGBT block doen not…

ANS 1 *Types of power converter circuits employed in an electric and HEVs- Power electronics is the application to control and conversion of electric power. A power converter is a process of converting electric energy  from one form to another. A power converter is an electromechanical device for converting electrical…

ANS 1 CONCLUSION: Thus we can see that for 3 number of cycles at the given conditions, the vehicle can travel for only 41.1 km. * If we increse the number of cycles then the vehicle can travel above 45 km.   ANS 2 We can see that by increasing the battery capacity, the vehicle can travel for more than 53kms in the…

ANS 1 Difference between mapped and dynamic model of engine: Powertrain Blockset provides two types of Engine models: mapped and dynamic. Mapped engines represent macro engine behavior as a set of lookup tables (brake torque, fuel flow, air mass flow, exhaust temperature, efficiency and emissions) as a function of commanded…

Aim : Make a simulink model of Doorbell using solenoid block. Report: 1.In simulink Model of door bell using solenoid block,we need a switch,solenoid,battery and a plunger.                                2. Now first a 'solenoid block' is taken to represent a solenoid in the model, then to represent battery we have taken…
