Enhancing Liquid Cooling Systems in Electric Vehicle Batteries: Principles and Nanomaterial Innovations
Year: 2024
Type: article
Abstract: As electric vehicles (EVs) continue to grow in popularity, managing the thermal behavior of lithium-ion batteries (LIB) has become increasingly important. Higher energy densities in batteries lead to significant heat generation during operation, which can cause short circuits, fires, and overall performance degradation. To maintain safety and performance, liquid cooling systems play a crucial role in controlling battery temperatures. This paper explores the principles behind liquid cooling systems used in EV batteries and discusses recent methods to enhance their efficiency. Special focus is given to the integration of nanomaterials, such as metal oxides, graphene, and carbon nanotubes, into base coolants to form nanofluids. These nanomaterials, known for their high thermal conductivity and large surface area, improve the thermal properties of the coolant, facilitating better heat absorption and dissipation. By using nanofluids, the cooling performance can be significantly enhanced, reducing the risk of localized overheating and ensuring safer, more efficient battery operation.
