Abstract - Choosing a proper cooling method for a lithium-
(Li-ion) battery pack for electric drive vehicles (EDVs) and making an optimal cooling control strategy to keep the temperature at an optimal range of 15°C to 35°C is essential to increasing safety, extending the pack service life, and reducing costs
ion (Li-ion) battery pack for electric drive vehicles (EDVs) and making an optimal cooling control strategy to keep the temperature at an optimal range of 15degree C to 35degree C is essential to increasing safety, extending the pack service life, and reducing costs. When choosing a cooling method and developing strategies, trade-offs need to be made among many facets such as costs, complexity, weight, cooling effects, temperature uniformity, and performance. This paper considers two cell-cooling methods: air cooling, direct liquid cooling and compared the results with static cell temperature. To evaluate their effectiveness, these methods are assessed using a typical large capacity Li-ion pouch cell designed for EDVs from the perspective of coolant parasitic power consumption, maximum temperature rise, temperature difference in a cell, and additional weight used for the cooling system. Used a state-of-the-art Li-ion battery electro-chemical thermal model. The results show that under our assumption an air-cooling system consumed more energy to keep the same average temperature. A direct liquid cooling system has the lowest maximum temperature rise.
Energy-saving and environmentally friendly electric drive vehicle (EDV) adoption in the market is in- creasing and has more potential if batteries have more energy, travel longer, and are less expensive. The battery thermal management system to keep the temperature at an optimal range of 15°C to 35°C is essential for lithium-ion (Li-ion) battery packs in electrical vehicles (EVs) and hybrid electrical vehicles (HEVs) to extend lifetime and ensure operating safety. During vehicle operation, considerable heat is generated in the battery pack that needs to be rejected. How to remove the generated heat, and keep the temperature uniform has become a challenge because of the high requirement of gravimetric and volume energy in EDVs. Several cooling methods have been proposed and researched. 1.1 Problem Statement

Choosing a proper cooling method for a lithium-ion (Li-ion) battery pack for electric drive vehicles (EDVs) and making an optimal cooling control strategy to keep the temperature at an optimal range of 15 °C to 35 °C is essential to increasing safety, extending the pack service life, and reducing costs. When choosing a cooling method and developing strategies, trade-offs need to be made among many facts such as costs, complexity, weight, cooling effects, temperature uniformity, and parasitic power.
1. INTRODUCTION Lithium-ion (Li-ion) batteries are widely known for their energy efficiency and are becoming the battery of choice for designers of electric vehicles (EVs). However, these batteries lose efficiency quickly with sudden changes in temperature. One way to control rises in temperature (whether environmental or generated by the battery itself) is with liquid cooling, an effective thermal management strategy that extends battery pack service life. To study liquid cooling in a battery and optimize thermal management, engineers can use Multiphysics simulation. Li-ion batteries have many uses thanks to their high energy density, long life cycle, and low rate of self-discharge. That’s why they’re increasingly important in electronics applications ranging from portable devices to grid energy storage — and they’re becoming the go-to battery for EVs and hybrid electric vehicles (HEVs) because of their high energy density compared to their weight.
