Embodiment Construction
[0037] Batteries with phase change materials (PCM), such as lithium-ion batteries, can improve heating and cooling capabilities under different vehicle operating conditions. PCM can help minimize unwanted operating temperature variations, increase heating and cooling uniformity, and reduce heating and cooling requirements.
[0038] Batteries utilizing PCM are able to control temperature excursions and maintain temperature uniformity with little or no active cooling components such as fans, blowers or pumps present in air / liquid cooling systems. Thus, a compact, light-weight, energy-efficient system can be obtained with energy usage of battery life and performance over the full operating range of hybrid electric vehicles (HEV) / plug-in electric vehicles (PEV) is optimized.
[0039] The thermal performance and heat transfer enhancement methods of various PCMs are described in Kenisarin and Mahkamov, "Solar energy storage using phase change materials", Renewable and Sustainable E...
