Turning LED ON and OFF using different tasks by Free RTOS api.

The logic which is required in this is that if the power demand from the vehicle is less than the minimum FC power than the FC must go on standby and the power should be supplied from the battery storage system and if the power demand is greater than the min FC power than the FC should be used and if the power demand of…

   Answer 1:-  False.  Ultracapacitors can be used as energy storage devices similar to a battery, and in fact are classed as an ultracapacitor battery. But unlike a battery, they can achieve much higher power densities for a short duration. They are used in many hybrid petrol vehicles and fuel…

1) Fuel cells are classified primarily by the kind of electrolyte they employ. This classification determines the kind of electro-chemical reactions that take place in the cell, the kind of catalysts required, the temperature range in which the cell operates, the fuel required, and other factors. These characteristics,…

Aim :Design and simulation of Buck converter for Auxiliary load in EV Given Input voltage is 48V, Output voltage is 12 V Load current is 10A The calculations are done on the to find the values of L C and R Vin=D*Vout where Vin- input voltage           Vout- output voltage        …

1) Initially calculations are done so as to find out the capacity of the battery. After deciding the capacity next step is to find out the number of series parallel combination of cell. Anode and cathode materials are selected based on their properties.   The terminals of the  batteries in series and parallel are spot…

Here 10 cells are connected in series and hence the voltage vill 72V and current will not change so current is 5.4Ah.As the battery model is identical parameters of only one battery is annalysed battery and  other cells are assumed same. A bus selector select the signals from the 'm' port of the generic battery and…
