In this paper, an innovative liquid cooling plate (LCP) embedded with phase change material (PCM) is designed for electric vehicle (EV) battery thermal management. The proposed cooling plate is named “hybrid cooling plate” as it takes advantage of both active (liquid) and passive (PCM) cooling methods.
The prototypes were extensively tested within the battery packs and proven to be highly effective at removing heat from the batteries. Ultimately, the highly-efficient and lightweight liquid cold plates were able to dramatically increase thermal performance while decreasing the overall weight of the battery pack by over 40%.
Generally, the liquid cooling plate is required to have high heat dissipation power, which can promptly dissipate the excess heat generated during the operation of the Tesla Powerwall lithium battery, avoid excessive temperature rise, and have high reliability.
The light-weight structure of the hybrid cooling plate, the cooling effectiveness, and the cold temperature performance indicate that the cooling plate developed in this study is a promising candidate for thermal management of battery packs in an electric vehicle.
This paper presents a new concept of the liquid cooling plate for thermal management of Li-ion batteries in electric vehicles. In the proposed cooling plate, a phase change material is embedded inside the cooling plate. The cooling plate is named “hybrid liquid cooling plate”, as it provides both active and passive cooling methods.
