Transportation sector is found to be the largest user of oil. It is the second largest producer of CO2, contributing to environmental pollution. Electric Vehicle came into existence as a solution to this problem. It was necessary to balance the battery pack in the electric vehicles to achieve the requisite driving range. This paper proposes a 2-mode battery balancing system with renewable energy integration. The 2 operating modes are: solar-balancing, charge-balancing. When the vehicle is moving, solar cell charges the cell with the lowest SOC and the system is said to be in solar balancing mode. In charge balancing mode vehicle will be parked in the charging station and the cell with lowest SOC will be charged. If the sun’s energy is available when the vehicle is parked, it will be stored in the storage system. The proposed system will eliminate the wastage of energy that occurs in the conventional battery balancing system thereby improving the efficiency of the system and increasing the driving range.
