<2022> Global Development Trend & Market Outlook for EV Battey Packs (~2030)

 

Since its rapid growth in 2021, the electric vehicles industry is anticipated to have an outstanding progress in the following decade. Particularly, with the introduction of platforms dedicated to electric vehicles, the trend of battery module and pack development will continuously head in the direction for lightweight and low-cost products. With changes in the chemical composition of battery cells, pack design, and material choices, the level energy density of pack has been increasing. Due to the introduction of module-less pack technology, the level energy density is expected to grow further, reaching 187Wh/kg in 2025 and 215Wh/kg in 2030. This report investigates how global OEMs respond to such changes in the industry and analyzes the development status and trend of battery pack. In addition, this report provides the most up-to-date information about the global scale and prospects of battery pack and related parts as well as the trend and cases of battery pack patents.

 

Chapter 1 gives a basic explanation on battery packs, while Chapter 2 investigates the detailed structure of battery packs and the trend of battery pack development by car OEMs. Chapter 3 offers the cost analysis on battery packs, and Chapter 4 describes the supply chain of battery packs and parts. Chapter 5 and 6 investigate the battery pack makers and part manufacturers. Chapter 7 provides an outlook about the scale of EV market and the battery pack market. Lastly, Chapter 8 shares the trend of patents related to battery packs and details of those patents. The chapter also includes the press and statistical data from the Korea Intellectual Proper Office about recent cases of patents in relation to the safety structure of batteries.
