The research project is related to the single seat three-wheel electric vehicle. Due to the high consumption of the oil in New Zealand (NZ) which have a direct impact on the economy, the authorities are now looking for an alternative source to power the vehicles and revolutionize the transport industry. There is another motive behind the development of electric vehicle (EV) which is linked with the environmental conditions of the country. The Internal Combustion Engine (ICE) vehicles increase the air pollution in the country and due to which the global warming has become a serious issue. To reduce the global warming effect and air pollution the electric vehicles have become a strong candidate or choice for the transportation. This project covers the electric vehicle in three parts: the Road Legal Status of EV in New Zealand, the Battery Electric System(BES), and Vehicle Design. There are some limitations which are associated with electric vehicles such as legislation does not encourage the people to purchase an electric vehicle, and the manufacturers are still interested in ICE vehicles. The research project proposes the desired policy for the EV in New Zealand. The possible design of the EV is proposed which is modeled in SolidWorks. Furthermore, the entire battery electric system and its management is included in the report which describes the proposed Battery electric system for single-seat electric vehicle. The primary goal in developing the battery electric system of the EV was to ensure that it has long driving range. The current EV are struggling to achieve the long driving range. The design selected for the EV is Reverse-trike. The unique features include the shifting of the centre of mass of the more extensive position. This design provides more stability and traction to the vehicle as the weight shift is towards the front wheels of the car.
