Custom Temperature Cycling Test Chamber For New Energy Products Powering Future With Reliability

1. Introduction

2. Key Features

2.1 Precise Temperature Cycling

• Wide Temperature Range: The chamber is engineered to cover an extensive temperature spectrum, typically from - 70°C to 150°C. This broad range allows for the simulation of extreme cold, such as in polar regions where EVs might operate or solar panels could be installed, and high - temperature scenarios, similar to those in desert - based solar power plants or during peak - load operation of EV batteries.
• High - Accuracy Temperature Control: Equipped with advanced temperature - control algorithms and high - precision sensors, the chamber can maintain the set temperature within an accuracy of ±0.1°C during the cycling process. This level of precision is crucial as even minor temperature fluctuations can significantly impact the performance and lifespan of new energy products. For example, in the case of lithium - ion batteries, small temperature changes can affect the rate of chemical reactions, leading to variations in battery capacity and cycle life.
• Flexible Cycling Profiles: Users can customize complex temperature - cycling profiles. The heating and cooling rates can be adjusted according to specific test requirements, usually ranging from 1°C/min to 5°C/min. Additionally, the hold times at different temperature levels can be defined. For instance, a solar panel might require a slow - heating phase to mimic the gradual warming in the morning sun, followed by a rapid - cooling phase to simulate the sudden drop in temperature at sunset.

2.2 Customizable Interior Configuration

• Product - Specific Fixturing: The chamber can be customized with a variety of fixtures designed specifically for different new energy products. For EV batteries, specialized battery holders can be used to ensure proper thermal contact and secure placement during testing. Solar panels can be mounted on adjustable frames that allow for different angles of exposure, similar to their real - world installation. Wind turbine components, such as bearings and generators, can be held in fixtures that simulate their operational positions.
• Multi - Sample Testing Capability: It has the capacity to accommodate multiple samples simultaneously. This is particularly beneficial for batch testing of small - scale new energy components, such as battery cells or solar cells, enabling manufacturers to save time and resources while obtaining a comprehensive understanding of the performance variability within a production batch.

2.3 Advanced Monitoring and Data Acquisition

• Multi - Parameter Monitoring: A comprehensive monitoring system is integrated into the chamber. It continuously monitors temperature, as well as other relevant parameters such as humidity (if required for specific tests), voltage, and current in the case of electrical components. For example, when testing EV batteries, the system can monitor the charging and discharging voltage and current profiles under different temperature conditions to evaluate the battery's performance.
• Real - Time Data Logging: The chamber is equipped with a data - logging system that records all monitored parameters in real - time. This data can be stored for later analysis, allowing manufacturers to identify trends, detect early signs of component degradation, and optimize the design and manufacturing processes based on the test results. The data acquisition frequency is adjustable, typically from [Min Freq] Hz to [Max Freq] Hz, ensuring that even the most rapid changes in the test parameters are accurately captured.
