温度对电池性能有重大影响。电池通过电化学反应释放能量，而较高的环境温度会促进这些反应。不同的电池化学有不同的最佳工作温度范围。根据电池的应用或气候，它们将被要求在更高或更低的温度下运行。
However, operating batteries at extreme temperatures also comes with risks. At higher temperatures, there is a reduction in internal resistance, which means higher electron mobility and greater charge/discharge rates. Nevertheless, studies have also shown operating a battery at elevated temperatures speeds up degradation, diminishing the cell’s life cycle.
Continuous exposure to high temperatures can also cause unwanted chemical reactions and result in gas, corrosion, or even fires and explosions. Moreover, a battery cell can enter into thermal runaway — when the cell heats up faster than heat can dissipate, causing a continuous increase in temperature. If one cell in the pack heats up, this can quickly cause the whole pack to overheat, undermining the safety of the system, machine, or surrounding people.
相反，较低的温度会降低电池性能和能量容量。电化学反应不那么活跃，内部电阻增加，从长远来看会损害电池。这就是为什么在测试电池时将温度考虑在内是极其关键的。
为什么温度在电池测试中很重要？
Battery testers and researchers need to establish how a battery would react under different temperatures to see if they are suitable for their intended application and location of use. As new battery chemistries emerge or existing ones improve, researchers must conduct testing to determine the battery’s optimal temperature range for peak performance. Moreover, this helps determine whether it is suitable for conditions they are intended to operate in. Comprehensive testing under different temperatures also helps determine which conditions can negatively impact battery performance, and allow users to better prevent dangerous situations from occurring.
Arbin如何支持温度控制的测试
Arbin Instruments can support labs with various products when temperature-controlled testing is needed. Arbin provides three different types of battery temperature measurement options: thermocouple, RTD, and thermistor, depending on your testing needs. Thermal sensors provide reliable temperature readings so that labs can more completely assess a battery’s performance. The different sensor types are appropriate for certain ranges of temperature, with varying response times and susceptibility to electrical noise. Experts at Arbin Instruments are able to help labs evaluate the most appropriate sensor for the intended application.
How Arbin’s novel battery test chamber can help
Arbin’s novel “MZTC” Multi-Chamber 是一个电芯互相隔离的安全温箱，在一个台式装置里有8个独立的迷你温度室。由于每个迷你室都是自己的电池测试室，研究人员更容易确保测试室的温度稳定和均匀，大大减少了较大测试室可能出现的温度不均的问题。它还为用户提供了更大的温度控制和一个安全的测试环境。如果一个试验室的电池过热或进入热失控事件，它不太可能连带到其他迷你试验室的其他电池。
Moreover, Arbin offers the “MTCI” module, an interface that is compatible with many 3rd party temperature chambers when temperature and/or humidity-controlled environments are required. Using RS232 communication, users can set the temperature of a chamber during testing. Paired with Arbin’s MITS Pro software, the user-friendly interface makes it easy for researchers to not only set the temperature of the test chamber, but also synchronize a group of channels where the temperature is adjusted only after all the channels have reached the same temperature point.
