The National Aeronautics and Space Administration (NASA) have studied on the Earth’s climate change for decades. In their studies, motor vehicles are the greatest contributor to the global warming issues [1]. The majority of the vehicles on the road are heavily dependents on fossil fuels. Hence, this is emitting massive Greenhouse Gas into the atmosphere. In addition, fossil fuels are being used in a non-sustainable rate. Therefore, Electric Vehicle (EV) will be an alternative solution to replace fossil fuels vehicle. The EV is foresee to be the solution to sustainable transport system and reduce carbon emission. The battery technologies implementation will be the main consideration for an EV. The battery of an EV have to be compromised with energy storage capability, weight, lifespan and cost. The propulsion of engine will require different battery system. Thus, the required battery system is varied with the type of engine used in EV. Moreover, the batteries are the most expensive part in an EV. Hence, it is important to have a suitable Battery Management System (BMS) to ensure the battery operate optimally with maximum reliability and safety [2]. The scope of this report will cover design consideration of the Lithium-ion BMS from the hardware aspect. This compromise defining requirements of the system, design architecture, hardware designing with consideration of industry standard, and implementation of control circuits to ensure optimum performance from the system. This project was carried out in collaboration with ERIAN lab. The overall design and procedure was co-supervised by Dr Li Kaiyuan from ERIAN lab.
