Protect Battery Safety: Lab Companion Rapid Temperature Change Chamber--Specialized Testing Solution for New Energy Battery Packs

1. Core Requirements for Environmental Testing of New Energy Vehicle Battery Packs

1.1 Correlation Between Temperature Stress and Battery Operational Safety

As the core component of new energy vehicles, power battery cells, modules and complete battery packs are constantly exposed to ambient temperature fluctuations and heat generated during charging and discharging in daily operation. Repeated high and low temperature cycles cause thermal expansion and contraction of materials as well as changes in internal stress. Long-term exposure will lead to performance degradation and potential structural risks.

Rapid temperature change chambers and thermal cycle chambers simulate full-lifecycle temperature conditions of vehicles in advance, so as to fully identify potential defects of batteries. This fundamentally improves product safety and service life. As industrial standards become increasingly stringent, higher requirements are set for the temperature change rate, load capacity and chamber size of testing equipment.

1.2 Specifications for Thermal Cycling Tests per Automotive Standards

Current testing of power batteries strictly complies with automotive-grade standards, which define clear specifications for temperature range, temperature ramp rate, cycle times and combined temperature & humidity control. Conventional tests require thousands of high-low temperature cycles. Some reliability verifications also adopt combined stress tests with humidity and vibration.

The Yangtze River Delta region including Shanghai, China is home to numerous new energy vehicle manufacturers and supporting battery enterprises, with strong demands for production line testing, R&D certification and batch screening. Local customers require not only high-performance testing equipment, but also efficient and professional technical support and maintenance services.

2. Core Technologies of Lab Companion Dedicated Rapid Temperature Change Chambers for Battery Packs

2.1 Large-capacity Integrated Chamber for Full-range Battery Testing

To adapt to the large size and diverse specifications of battery packs, the equipment adopts a large-capacity integrated chamber with optimized internal layout. It is suitable for testing cells, modules and complete battery packs of different dimensions.

Reinforced thermal insulation and sealing structures effectively reduce heat exchange between inside and outside the chamber. A stable internal temperature field is maintained during prolonged high-low temperature cycling, perfectly meeting the requirements for large-scale battery pack testing.

2.2 High-speed Temperature Change & Adaptive Load Technology

The equipment delivers a maximum temperature change rate of 25°C/min. Equipped with an adaptive load system, it offsets heat generated by batteries during charging and discharging in real time, ensuring stable and consistent temperature ramp rates even when test samples continuously produce heat.

The full product line covers a temperature range of -70°C ~ 180°C, fully satisfying all working condition tests for power batteries.

2.3 Integrated Temperature, Humidity & Vibration Testing

To meet the demand for combined environmental tests, the equipment supports synchronous control of temperature, humidity and vibration. It accurately simulates real driving scenarios such as outdoor exposure and driving on bumpy roads.

While achieving rapid temperature change, the chamber precisely regulates internal humidity. The anti-condensation design prevents damage to battery electrical components caused by low temperature and high humidity.

2.4 Dedicated Safety Alarm & Protection System

The equipment is equipped with multi-level early warning mechanisms for abnormal temperature and overpressure, with customized safety optimizations for battery testing scenarios. Once abnormal parameters are detected, the system triggers alarms and activates protective actions immediately to ensure safe and stable testing throughout the process.

3. Comprehensive Testing Solutions for Power Batteries at All Levels

3.1 Early Defect Screening for Battery Cells

At the front end of production, rapid temperature change chambers conduct thermal cycle tests on individual cells. High-frequency temperature cycling eliminates early failure products, controls the quality of raw materials and reduces failure risks of finished modules and packs. The compact and efficient equipment is ideal for high-volume batch screening on production lines.

3.2 Working Condition Verification for Battery Modules

After assembly of battery modules, rapid thermal cycle chambers simulate temperature fluctuations accompanied by charging and discharging. They verify the stability of internal connections and heat dissipation systems.

The programmable controller supports complex cycle logic to replicate actual operating conditions of modules and complete long-term reliability validation.

3.3 Certification Testing for Complete Battery Packs

For vehicle certification of battery packs, large-chamber rapid temperature & humidity change chambers perform extreme high/low temperature tests and alternating temperature-humidity tests. All technical parameters are in line with automotive certification standards. Reliable test data helps customers complete certification procedures efficiently.

3.4 Environmental Stress Screening for Mass Production

In the mass production phase, ESS (Environmental Stress Screening) chambers operate continuously to conduct stress screening on finished battery packs. Latent defects are fully exposed to ensure consistent quality of delivered products.
