Answer 1:Comparison of four different types of fuel cells and their applications: Fuel Cell Type Operating Temperature (°C) Electrolyte Fuel Applications Polymer Electrolyte Membrane (PEM) 60-110 Solid polymer membrane Hydrogen Transportation (cars, buses, trucks), portable power, auxiliary power units Alkaline Fuel…

a.) The max heat generation of the battery: There are 2 componeents for heat generation in the battery pack: -> Joules heat  -> Entropy heat Heat generated = Joules Heat + Entropy Heat   Joules Heat : froms ohms law we know that  V = IR when a current flowing through a resistance, there is a heat dissipated…

PART-A: 1. Search and list out the total weight of various types of aircrafts ? The aircraft gross weight (also known as the all-up weight and abbreviated AUW) is the total aircraft weight at any moment during its flight or during ground operation. An aircraft's gross weight will decrease during…

1. The traction force of a vehicle is naturally opposed by various opposing forces like friction offered by the road,air drag force,force of gravity due to upward hill descent & through braking which is externally applied to the wheels by braking mechanism(hydraulic-in case of conventional ICE vehicles) & in case…

1. A. Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’. This model shows the simulation of an H-bridge used to generate a chopped voltage and to control the speed of a DC motor. Here the power BJT switches act as chopper & by varying the duty cycle of the switches…

1. Below are the 4 types of power converter circuits but the first three types are only used in EV's & HEV's. These are: 1. AC to DC converter(Also called rectifiers): this type of converter converts the AC supply to a DC supply. Electric power is transmitted from power plants to our homes in AC form which is at a…

Here i have considered HEV Multimodal reference application model from the MATLAB Help documentation for below analysis :- 1. 1. Mapped model: A mapped engine model uses a set of steady-state lookup tables to characterize engine performance.The tables provide overall engine characteristics,…

1. From the results in the ADVISOR tool - For EV_defaults_in file & a cargo mass of 500 kg with all other conditions kept as default, the vehicle will not travel for 45 km with FTP drive cycle. For FTP drive cycle with 1 cycle, It will cover only 17.7 kms & at the end of drive cycle the battery SOC is 60% ,The…

OBJECTIVE: 1.To analyze the ATV model in system level environment using matlab & simulink. 2.To study the behaviour of the system to different simulated inputs & parameters through characteristics & plots. 3. To analyze the model,justify & explain in detail the different simulink & simscape blocks used.   REPORT: 1. What…

1. The washing machine logic is designed as follows: There is an indicator lamp for both power supply(red means no power supply & green means power supply available) & water supply(red means no water supply & blue means water supply available). An indicator is also provided for indicating the status of the…

Door-bell: 1. The door bell system as in the model is operated by a controlled switch which is switched on & off every 2 sec. In order to control the switch we give a input triggering signal using a pulse signal,which is set to a frequency of 0.25,as it has a period of 4seconds with 50% duty cycle.Based on the time…
