1. Introduction
With the booming development of the electric vehicle industry, the
battery, as the core component, directly determines the market
competitiveness of electric vehicles in terms of its performance,
safety, and reliability. Electric vehicle batteries need to operate
stably in various complex environments, ranging from the frigid
polar regions to the scorching desert areas, from the high -
altitude mountainous regions to the humid coastal areas. The custom
environmental battery test chamber has emerged as a powerful tool.
It provides electric vehicle battery manufacturers, research
institutions, and quality control teams with a means to simulate
real - world environmental conditions. By comprehensively testing
the performance of batteries in different environments, it helps to
enhance battery quality and propel the electric vehicle industry to
new heights.
2. Key Features
2.1 Precise Environmental Simulation Capability
- Wide - Range Temperature Simulation: The test chamber can achieve an ultra - wide temperature
adjustment from - 40°C to 120°C. In low - temperature environments,
it can simulate the working state of batteries when electric
vehicles are driving or parked for a long time in extremely cold
winters in polar regions, detecting the capacity attenuation,
charging performance, and changes in internal chemical reactions of
the batteries at low temperatures. In high - temperature
environments, it can simulate the heat - generation situation of
batteries during frequent fast - charging or long - time high -
speed driving in hot climates, evaluating the thermal stability,
heat - dissipation performance of the batteries, and the impact of
high temperatures on battery life. The temperature control accuracy
can reach ±0.3°C, ensuring the accuracy and repeatability of test
results.
- Accurate Humidity Regulation: The humidity regulation range is from 10%RH to 95%RH, with an
accuracy control of ±2%RH. High - humidity environments may cause
corrosion of the battery casing and short - circuits in the
internal circuits, while low - humidity environments may affect the
performance of the battery electrolyte. By precisely simulating
different humidity conditions, the moisture - proof performance,
sealing performance of the batteries, and their stability in
changing humidity environments can be tested. For example, testing
the insulation performance of batteries in high - humidity
environments ensures the safety of batteries in humid conditions.
- Altitude Simulation (Optional): Some advanced test chambers are equipped with an altitude
simulation function, which can simulate the air pressure changes
from sea level to high - altitude regions. In high - altitude
areas, the air is thin, and the heat - dissipation methods and
chemical reaction rates of batteries will change. By simulating the
air pressure environments at different altitudes, the performance
of batteries under different air pressure conditions can be
evaluated, providing data support for the use of electric vehicles
in plateau regions.
2.2 Integration of Battery Characteristic Testing Functions
- Charge - Discharge Performance Testing: The test chamber is integrated with high - precision charge -
discharge equipment, which can test electric vehicle batteries in
various charge - discharge modes. It can simulate different
charging speeds, such as fast - charging and slow - charging, and
different discharge conditions, such as urban road driving and high
- speed driving, to test key performance indicators of batteries
under various charge - discharge conditions, including capacity,
charge - discharge efficiency, and cycle life. Through the analysis
of charge - discharge curves, the performance change laws of
batteries can be deeply understood, providing a basis for the
optimization of the battery management system.
- Internal Resistance Testing: Real - time monitoring of the changes in the internal resistance
of batteries under different environmental conditions. Internal
resistance is an important parameter reflecting the health status
of batteries. An increase in internal resistance may indicate that
there are faults or aging inside the battery. By accurately
measuring the internal resistance, potential problems of batteries
can be detected in a timely manner, and maintenance or replacement
can be carried out in advance to ensure the safe operation of
electric vehicles.
- Battery Thermal Management System Testing: Electric vehicle batteries require an effective thermal
management system to maintain an appropriate working temperature.
The test chamber can simulate different environmental temperatures
and battery working states, testing the cooling and heating effects
of the thermal management system, as well as its ability to balance
and control the battery temperature. For example, in a high -
temperature environment, testing whether the thermal management
system can quickly reduce the battery temperature to a safe range
to avoid performance degradation and safety hazards caused by
overheating of the battery.
2.3 Customized and Intelligent Design
- Flexible Internal Structure Customization: According to the different sizes and shapes of electric vehicle
batteries, the internal structure of the test chamber can be
customized. It is equipped with various types of battery fixtures
and fixing devices to ensure that the batteries can be stably
placed during the test and achieve good electrical connection with
the test equipment. At the same time, the internal space can be
reasonably arranged according to test requirements, facilitating
the installation of various sensors and monitoring devices to
comprehensively collect various data of the batteries during the
test.
- Intelligent Control System and Data Collection and Analysis: An advanced intelligent control system is adopted. Users can
easily set various test parameters, such as environmental
temperature, humidity, altitude, charge - discharge mode, etc.,
through the human - machine interface, and can monitor various data
in real - time during the test process. The system has a powerful
data collection and analysis function, which can automatically
record the performance data of batteries under different
environmental and test conditions, generate detailed data reports
and trend curves. Through data analysis, the performance advantages
and disadvantages of batteries can be quickly evaluated, providing
strong support for the research and development and improvement of
batteries.
