As the largest developing country, China has been adhering to the spirit of “pursuit of excellence” and has invested a lot of manpower and material resources in science and technology innovation, and the NEV battery industry is just one of the projects. The Chinese government has introduced support policies to develop this industry successively.
One of the first steps to reduce the battery cost in design and manufacturing was driven by standards societies such as the International Standard Organization (ISO) and the German Association of the Automotive Industry (VDA). They regulated the cell size to be used in Electric and Hybrid Vehicles.
A battery system contains different mechanical, electrical, and electronic components. Each of them must be considered in the design process . The definition of the battery layout is crucial because this aspect directly impacts cost, thermal dissipation, manufacturing phase, and end-of-life processing.
The development of the battery industry is crucial to the development of the whole NEV industry, and many countries have listed battery technologies as key targets for support at a national strategic level, which means that the NEV battery industry as a new industry has stepped on the stage of the development of this era. .
Recent design methods are focused on optimization and life cycle improvements. Battery design and manufacturing decisions will be integrated in the future. Data-driven approaches are emerging with the possibility of a user-centered design. A design platform could integrate simulations, data-driven, and life cycle methods.
Nowadays, battery design must be considered a multi-disciplinary activity focused on product sustainability in terms of environmental impacts and cost. The paper reviews the design tools and methods in the context of Li-ion battery packs. The discussion focuses on different aspects, from thermal analysis to management and safety.
