When it comes to new energy vehicles, what attracts much attention is the performance of batteries, whose safety and durability largely determine the user experience of new energy vehicles. As an environmental reliability testing equipment, the high and low temperature test chamber has gradually emerged in recent years with the emerging power of new energy vehicles. Today, let's talk about the temperature and humidity testing of new energy vehicle power batteries.
Application of High and Low Temperature Test Chambers in the Power Battery Industry
1. Purpose of High Temperature Test for Power Batteries
The high-temperature test aims to evaluate the performance and reliability of power battery systems in high-temperature environments. Experiments usually simulate actual high-temperature conditions by placing the battery system in a high-temperature room or using a hot plate for heating. During the experiment, monitor and record the temperature, voltage, current, capacity attenuation and other parameters of the battery system.
2. The impact of high temperature on the battery system
High temperature environments may have various adverse effects on battery systems, such as accelerating capacity decay, increasing internal resistance, and reducing battery power output capacity. In addition, the high temperature may also cause the safety risk of Thermal runaway, overheating and even fire of the battery system. Through high-temperature operation tests, the temperature control ability, performance degradation, and safety performance of the battery system in high-temperature environments can be evaluated.
3. Evaluation indicators for high-temperature testing
In high-temperature testing, commonly used evaluation indicators include:
Temperature response: Monitor the temperature changes and stability of the battery system in high-temperature environments.
Capacity decay: Measure the capacity loss of a battery system under high temperature conditions to evaluate its lifespan characteristics.
Battery internal resistance: Measure the change in internal resistance of the battery system under high temperature environment to evaluate its power output capability.
Safety performance: observe the safety performance of the battery system during high-temperature operation, including temperature control, Thermal runaway risk, etc.
4. High temperature test operation specifications
In high-temperature testing, it is necessary to continuously conduct the test according to the specified temperature range and time. By conducting experiments and recording relevant data, information on the performance and safety performance of battery systems in high-temperature environments can be obtained. Analyzing the experimental results can reveal the high-temperature adaptability, capacity decay trend, temperature control strategy, etc. of the battery system. Based on the analysis results, targeted improvements can be made to the design and control strategies of the battery system to enhance its high-temperature working ability and safety.
How to Choose the Right High and Low Temperature Test Chamber Brand
Choosing a suitable supplier of high and low temperature test chambers can be quite challenging. Currently, there are many brands of high and low temperature test chambers both domestically and internationally. How to choose the suitable test equipment from numerous suppliers needs to consider the following points:
1. Test capability
Temperature range, uniformity, fluctuation, rate of temperature rise and fall, accuracy, and other factors are important considerations for selecting a high and low temperature test chamber, which determines whether the equipment can meet your testing requirements.
3. Safety characteristics -
Reliability, service life, and failure rate determine your user experience and testing progress.
4. Maintenance Requirements -
The speed of after-sales response and service quality determine your subsequent usage costs, and are also important factors to consider when choosing a manufacturer of high and low temperature test chambers.
In summary, selecting a suitable high and low temperature test chamber requires first determining one's own testing needs, such as temperature and humidity range, size of the tested piece, etc; Furthermore, it is necessary to consider factors such as the usage environment to choose the appropriate device size for oneself; Of course, it is also important to consider the supplier's research and development capabilities, manufacturing level, etc.
