全球电动汽车电池冷却市场 - 2023-2028 年预测Global EV Battery Cooling Market - Forecasts from 2023 to 2028 |
电动汽车 (EV) 电池冷却是电动汽车设计和运行的一个重要方面。 这是因为电池必须保持适当的温度范围,以确保最佳性能、寿命和安全性。 针对铅酸和锂离子电池的电动汽车电池冷却系统主要有三种类型:风冷、液冷和风扇冷却。 电动汽车电池冷却用于多种车型,包括纯电动汽车、混合动力汽车和插电式混合动力汽车。 电动汽车电池冷却系统的增长是由于对电动汽车的需求增加、对电池安全和性能的日益担忧以及遵守政府排放和燃油经济性法规的需要。
电池在工作过程中会产生热量,过多的热量会损坏电池芯、降低容量并缩短电池寿命。 因此,需要电池冷却系统来调节温度并防止过热。 电动汽车电池冷却系统可防止热失控并降低电池相关事故的风险,使电动汽车更安全。 由于温度较低的电池充电速度较快,而温度较高的电池充电速度较慢,因此电池冷却系统有助于调节温度并保持充电时间恆定。 电动汽车电池冷却对于保持最佳电池性能、安全性和可靠性至关重要,并且已成为电动汽车设计和运行的一个关键方面。 多个国家/地区的政府已实施有关电动汽车电池冷却的法规,以确保电动汽车的安全和性能、促进其采用并减少其对环境的影响。 随着对电动汽车、电池效率和安全性、政府法规和技术进步的需求不断增加,对电动汽车电池冷却的需求也将增加。 据国际清洁交通理事会(ICCT)预测,2022年全球电动汽车产量将达到820万辆,增长40%,较2021年增加230万辆。 据韩国汽车製造商协会(KAMA)统计,2020年,韩国共发生11起电动汽车电池起火事故。 2021年,中国政府将出台新的电动汽车安全标准,其中包括电池安全和热管理要求,以确保中国电动汽车的安全性和可靠性,促进电动汽车的普及。 这表明电动汽车电池冷却未来将会有很大的需求。
亚太地区是全球最大、增长最快的电动汽车市场的所在地,其中包括中国、日本、印度和韩国。 这是由于该地区对电动汽车的需求、城市化进程的加快、空气污染问题的加剧以及气候变化。 2021年,中国政府推出《新能源汽车产业发展规划》,推动电动汽车市场增长。 该计划包括购买电动汽车的补贴、对电动汽车製造商的税收优惠、对电动汽车技术研发的投资以及充电基础设施和电池冷却系统的开发。 到2021年,道路交通和公路部将要求电动汽车配备符合一定标准的电池冷却系统,以将电池温度保持在一定范围内,并能够检测温度变化并做出反应。 2020年,日本政府公布了“绿色新政”理念,目标是到2050年实现碳中和,电池冷却需求预计将进一步增加。 这些因素正在推动亚太地区电动汽车电池冷却的增长。
Electric vehicle (EV) battery cooling is an important aspect of electric vehicle design and operation, as it is necessary to maintain a suitable temperature range for the battery cells to ensure optimal performance, longevity, and safety. The three main types of EV battery cooling systems for lead-acid and lithium-ion batteries include air cooling, liquid cooling, and fan cooling. EV battery cooling is used in different vehicle types, such as battery electric vehicles, hybrid electric vehicles, and plug-in hybrid electric vehicles. The growth of EV battery cooling systems will be due to the increasing demand for electric vehicles, rising concerns over battery safety and performance, and the need to comply with government emissions and fuel efficiency regulations.
Batteries generate heat during operation, and excessive heat can damage battery cells, reduce capacity, and shorten the battery's lifespan. Therefore, battery cooling systems are necessary to regulate the temperature and prevent overheating. EV battery cooling systems help prevent thermal runaways and reduce the risk of battery-related accidents, making electric vehicles safer. Colder batteries charge faster, while hotter batteries charge slower, and battery cooling systems help regulate the temperature and ensure consistent charging times. EV battery cooling is essential for maintaining optimal battery performance, safety, and reliability, making it a critical aspect of electric vehicle design and operation. Several countries' governments are implementing regulations on EV battery cooling to ensure the safety and performance of electric vehicles, promote their adoption, and reduce their environmental impact. The demand for EV battery cooling increases with the growing demand for electric vehicles, battery efficiency and safety, government regulations, and technological advancements. According to the International Council on Clean Transportation (ICCT), global electric vehicle production increased by 40% in 2022, reaching 8.2 million vehicles, with an increase of 2.3 million vehicles compared to 2021. According to the Korea Automobile Manufacturers Association (KAMA), in 2020, 11 incidents of electric vehicle battery fires took place in Korea. In 2021, the Chinese government introduced new safety standards for EVs that set battery safety and thermal management requirements to ensure the safety and reliability of EVs in China and promote the adoption of electric vehicles. This demonstrates that global EV battery cooling holds a great demand in the future.
The Asia Pacific region is home to the world's largest and fastest-growing electric vehicle markets, including China, Japan, India, and South Korea, due to the demand for electric vehicles in the region, increasing urbanization, growing concerns about air pollution, and climate change. In 2021, the Chinese government launched the "New Energy Vehicle Industry Development Plan" to promote the growth of the electric vehicle market, which includes subsidies for electric vehicle purchases, tax incentives for electric vehicle manufacturers, investments in research and development of electric vehicle technologies, and development of charging infrastructure and battery cooling systems. In 2021, the Ministry of Road Transport and Highways of India mandated that electric vehicles must have a battery cooling system that meets certain standards to maintain the battery temperature within a certain range and be able to detect and respond to any temperature changes. In 2020, the Japanese government announced the "Green New Deal" initiative, which aims to achieve carbon neutrality by 2050, and the government plans to promote the adoption of electric vehicles and expand the charging infrastructure for EVs, which will further increase the demand for EV battery cooling. These factors all add to the EV battery cooling growth in Asia Pacific.
