With the continuous improvement of battery performance requirements in industries such as new energy vehicles, energy storage power stations, and 3C electronics, laboratories have proposed higher standards for stability testing of batteries in harsh environments. The Shanghai Yetuo Battery High and Low Temperature Test Chamber is a controllable temperature environment simulation device designed to meet this demand, widely used in battery research and development, quality inspection, aging testing, and comprehensive evaluation.
1、 What is a battery high and low temperature test chamber?
The battery high and low temperature test chamber is a testing equipment specifically designed to simulate the performance of batteries under harsh weather conditions such as high temperature, low temperature, rapid cooling and heating. By controlling the temperature inside the chamber (some models can be humidified), this device helps researchers evaluate the charging and discharging performance, capacity changes, structural integrity, and failure risk of batteries at different temperatures.
2、 Main functional features
1. Wide temperature control range, suitable for multi scenario testing
The device supports a temperature adjustable range of -70 ℃~150 ℃ (commonly -40 ℃~150 ℃), covering various application scenarios from extreme cold to high heat, meeting various needs such as battery thermal cycling testing, high and low temperature storage, and environmental stress testing.
2. High precision control system
The temperature fluctuation range is small (± 0.5 ℃), and the heating and cooling rate can be adjusted to ensure highly reproducible and traceable testing conditions, especially suitable for long-term aging and high-frequency testing.
3. An has complete security measures in place
Equipped with functions such as over temperature protection, door lock linkage, overload alarm, smoke alarm, etc., to ensure the human-machine safety during the testing process and prevent risks such as battery thermal runaway, swelling, and leakage.
4. Customizable multi-channel testing interface
Can be used in conjunction with charge and discharge testers and electrochemical workstations for synchronous testing of electrical performance at high and low temperatures, improving testing efficiency and data correlation.
3、 Typical application scenarios
Testing of batteries for new energy vehicles
Verify the capacity loss and voltage changes of battery modules in high cold (such as below -20 ℃) or high temperature (such as above 60 ℃) environments, and predict the stability of actual road use.
Assessment of Weather Resistance of Consumer Electronics Batteries
Detect the durability of mobile phone, laptop, and wearable device batteries under daily temperature fluctuations to prevent shortened lifespan due to environmental stress.
Environmental adaptation testing of energy storage batteries
Simulate the battery performance of solar and wind energy storage equipment under long-term outdoor exposure to ensure the long-term reliable operation of the system.
Transportation and storage full testing
Test whether the battery will experience performance degradation or potential safety hazards when encountering poor temperature control during logistics and overseas transportation.
4、 Core Technology Highlights
Intelligent touch control system: supports multi-stage program control, curve setting, data recording and export
Corrosion resistant inner liner structure: Made of SUS304 stainless steel inner liner, suitable for high humidity or acidic gas environments
Dual cooling system: imported compressor refrigeration+air duct circulation to ensure uniform temperature distribution
Optional observation window and monitoring camera: convenient for real-time observation of sample status, improving testing intuitiveness
5、 Purchase suggestions
Select the chamber volume based on the battery size (commonly 50L~1000L)
Clarify the temperature control range requirements (such as whether an extremely low temperature of -70 ℃ is required)
Evaluate whether humidity control or rapid temperature change function is needed
Is it necessary to achieve data linkage with third-party devices (such as charging and discharging motors)
Conclusion:
The stability of the battery not only determines its service life, but also concerns the overall bottom line of an. The Shanghai Yetuo Battery High and Low Temperature Test Chamber, as the core equipment for simulating environmental changes, uses precise temperature control to provide scientific support for every performance leap of battery products.
In this era of "environment first, verification based" research and development, it is an indispensable temperature guardian for every battery laboratory.
