An inner-city electric bus with 7,200kg weight and average speed of 72 km/hour operates using a hybrid power source of lithium-ion battery pack and a bank of super capacitor. equipped with a lithium battery pack and a bank of supercapacitor. The energy content of the supercapacitor bank is twice the regenerative breaking energy of the electric bus at average speed. The electric bus commutes 490 km per charged battery and consumes 400 Wh/km.
Design the supercapacitor bank to provide 100V output, based on supercapacitor cells with 3600F capacitance and 2V.
Calculate the energy density of the supercapacitor at the cell level, assume cells with 10cm diameter and 15 cm height.
3. Design the battery pack for the electric bus by assuming that the energy of regenerative breaking will not be used for commuting but used to run the vehicle’s accessories. The unit cell of the battery pack is a lithium-ion…
A rod coincident with the z-axis extends from 0 to -L. If the rod carries a uniform charge density of pL (a) calculate the electric field intensity at a point h on the z-axis. (b) Use your answer to show that when h>>L the rod behaves as a point charge of value plL . (c) How much larger than the length of the rod must h be in order that the answer to part b) is a reasonably accurate estimate.
The separation of two point charges with charges Q1=36pC and ,Q2=9pC respectively, is 3 cm. If a third point charge Q3 is placed on the line joining Q1 and Q2 at a distance d from Q1 find Q3 and d that ensures that the force on all charges is zero.
