One-axis heliodon used for testing of the model passive solar homes (a) at a large solar altitude angle and(b) at a small solar altitude angle Because the heliodon has only one axis (it has only one hinge), it cannot easily be used tosimulate the azimuth angle of the sun’s position. It is possible to simulate the azimuth of the sun,but the model home itself would have to be rotated to simulate the azimuth angle, rather than thetwo-by-four arm that holds the light. To

Iteration A (left) and Iteration B (right) of the paper pipe prototype.Iteration A used muffler clamps to secure a rolled-up sheet of 22” by 28” poster paper, but itsunrefined visual appeal, assembly approach and material dimensions were not ideal. To addressthese challenges, the second iteration featured paper at the desired pipe length of 22” and widthequivalent to the circumference of a 4” diameter pipe (12.56”).

Placing them side by sidewill not only make the charging station look less appealing, but it would also cause unbalanceload distribution on the overhang. The USB ports are installed opposite from each other, and thecharging station have two sets of USB ports. Each set has a total of four USB ports, giving thecharging station a total of eight USB ports. Figure 4.

parameters. When designing a BMS,design considerations must be made for cell balancing. Cell balancing is the process ofequalizing charge across all cells within a battery bank, either through dissipation as heat orthrough the transfer of energy from high power cells to low power cells. To better understand themechanics of cell balancing, the design team reviewed the research of B. Yildirim et al. found inreference [3]. This article covers three methods of cell equalization in battery energy storagesystems (BESS). Cell balancing is an integral component to maintaining SOH. While cells of thesame voltage may be used in a system, “manufacturing and thermal variations, differences ininternal impedances, and self-discharging rates” will cause variation

output of thecontroller is connected to the duty cycle of the DC-DC buck converter. The effects of changes insolar irradiance, temperature, and load on output power based on the two MPPT algorithms canbe studied. Figure 10 shows the response of PV power to the step and gradual changes in solarirradiance. It can be seen that both algorithms provide good dynamic and static responses.FractionalOCV method provides more stable power but it relies on accurately selecting theproportionality constant. Due to the perturbation nature of P&O method, the instantaneous powerfluctuates, which can be eliminated with filtering techniques.

However, how and which are the bestapproaches to better educate the next generation of power and energy engineers, remain openquestions. In addition of teaching courses in electrical machines and power systems, highereducation institutes must include new courses and topics into curriculum, such as renewableenergy systems, power electronics, smart grids, energy economics and management, to mention afew of them while still ensuring a four-year graduation timeframe [2-9].The modern power systems have been significantly changed from the very modest beginnings toone of the most complex and large system, perhaps the largest machine or
