The scarcity of fossil fuel and increasing pollution leads the use of Electrical Vehicles (EV) and hybrid electrical vehicle instead of conventional Internal Combustion (IC) engine vehicle. The scope of this paper is to design and develop an electrical vehicle fast charge controller using Battery Management System (BMS) with Cuk Converter that is powered by an electric motor which gets its supply from rechargeable batteries. This paper will focus on, main battery (lithium ion) and auxiliary battery (lead acid) parts of battery storage, aimed to fast charging of electrical vehicle. An electrical vehicle requires an on board charger (OBC) to charge the main as well as auxiliary battery. The objective of this paper is to design a charger to charge both the battery fast and to reduce the charging stress on main battery by employing an auxiliary battery in Battery Management System. Due to such BMS to enhance battery lifetime, to avoid prolonged charging and to reduce overall cost of battery management system. These proposed topological are simulated in MATLAB software and some results are show the performance of the system.
