The Battery UC configuration used in the paper enables the use of a less power rated converter thus decreasing the cost of the system and at the same time increasing the life time of the Battery bank as frequent charging and discharging is avoided. The control algorithm focuses on increasing the efficiency of the system by using single pedal driving scheme in which the regenerative braking is activated when the pedal is not operated thus giving a better control on the vehicle and less wastage of energy during braking. The flow chart of the control scheme used is also included in the paper.

These vehicles offer reduced environmental effects, good efficiency thus are going to dominate the ICE vehicles in near future. This paper discusses the architectures of different vehicles and the energy sources that can be used for vehicular application emphasising the advantages and disadvantages of each. Power converters that can be used to for controlling the electrical energy flow in an EV are also discussed in this paper

Most of the large scale solar farms employ flat plate photovoltaic concept, so the installation footprint and shadow effect causes a huge drop in the electrical efficiency of the system. This paper aims at developing a methodology to reduce the area requirements in solar power generation. It proposes the development of a triangular prism shaped solar photovoltaic unit, which would reduce the required area for installation of the panels as opposed to the conventional method. The paper consists of the study of a lab level experimental setup of the proposed model, and comparison of its performance with conventional flat plate solar cells. The use of reflecting mirrors within the setup helps improve the efficiency of the setup, than the panels placed in the same area by conventional method. It also includes scope of future development.

UC is simulated using MATLAB Simulink. The Battery UC configuration used in the paper enables the use of a
less power rated converter thus decreasing the cost of the system and at the same time increasing the life time of
the Battery bank as frequent charging and discharging is avoided. The control algorithm focuses on increasing
the efficiency of the system by using single pedal driving scheme in which the regenerative braking is activated
when the pedal is not operated thus giving a better control on the vehicle and less wastage of energy during
