温度对锂离子电池技术的寿命、性能和安全性有着重大影响，锂离子电池技术有望成为电动汽车（xEV）的首选储能技术。高温会使锂离子电池更快地退化，而低温会降低功率和能量能力，这可能会对成本、可靠性、续航里程或驾驶性能产生影响。xEV中电池组的热管理对于将电池保持在所需的温度范围内以及减少电池之间的温度变化至关重要，这两者都会影响寿命和性能。电池热管理系统在缩短电池寿命和提高性能方面提供的价值超过了其额外的成本和复杂性。电池热管理的基本工具是红外热成像、等温量热法、热导率仪和计算机辅助热分析设计软件。本演示文稿提供了NREL使用的这些工具的详细信息，我们认为这些工具是设计合适尺寸的电池热管理系统所必需的。
Temperature has a significant impact on life, performance, and safety of lithium-ion battery technology, which is expected to be the energy storage of choice for electric drive vehicles (xEVs). High temperatures degrade Li-ion cells faster while low temperatures reduce power and energy capabilities that could have cost, reliability, range, or drivability implications. Thermal management of battery packs in xEVs is essential to keep the cells in the desired temperature range and also reduce cell-to-cell temperature variations, both of which impact life and performance. The value that the battery thermal management system provides in reducing battery life and improving performance outweighs its additional cost and complexity. Tools that are essential for thermal management of batteries are infrared thermal imaging, isothermal calorimetry, thermal conductivity meter and computer-aided thermal analysis design software. This presentation provides details of these tools that NREL has used and we believe are needed to design right-sized battery thermal management systems.
