The maximum capacity it can test is typically several hundred kilowatt-hours, and it is compatible with common automotive battery chemistries such as lithium-ion (NMC, LFP, etc.), nickel-metal hydride, and lead-acid.
• Detection Sensitivity for Automotive Batteries: The voltage and current sensors have a detection sensitivity of as low as a few microvolts and microamps, respectively. This allows for the early detection of internal short circuits, even before significant changes in the battery's performance become apparent. The temperature sensors can detect temperature changes as small as 0.1°C, enabling precise monitoring of the thermal behavior of the battery. The gas sensors have a sensitivity range that can detect gas concentrations as low as a few parts per million, ensuring the timely detection of potentially hazardous gas emissions.
• Stress Application Limits for Automotive Scenarios: The mechanical vibration can be applied with a maximum force of several Newtons, depending on the battery size and test requirements. The temperature change rate can reach up to 800°C per minute, and the overcharge current can be set to a maximum of several times the battery's nominal charging current, all within safe operating limits to avoid unnecessary damage to the machine or the battery.
• Data Acquisition Rate for Automotive Testing: The data acquisition system can sample data at a rate of up to 2000 samples per second for each sensor, ensuring that no critical information is missed during the test. This high sampling rate is particularly important when dealing with rapid changes in battery parameters, such as during a sudden short circuit event, providing the detailed data needed for accurate analysis and diagnosis.

4. Product Functions

• Accurate Detection and Diagnosis of Inner Short Circuits in Automotive Batteries
  • The primary function of this machine is to provide highly accurate and detailed detection of internal short circuits within automotive batteries. By continuously monitoring the electrical parameters, temperature, and gas emissions, it can identify the subtle signs of a short circuit, such as a sudden drop in voltage, a spike in current, an abnormal temperature rise, or the release of specific gases. The comprehensive data analysis allows for a precise diagnosis of the location and nature of the short circuit. For example, if the voltage drop is more pronounced in a particular cell within a battery pack, it could indicate a short circuit in that cell. This information is invaluable for automotive manufacturers, as it enables them to take corrective actions, such as improving the manufacturing process, enhancing the quality of internal components, or redesigning the battery layout.
  • The machine can also predict the likelihood of a short circuit leading to a more severe event, such as thermal runaway. By analyzing the rate of temperature increase and the correlation with other parameters, it can provide an early warning, allowing for preventive measures to be taken. For instance, if the temperature is rising rapidly and the current is also increasing, it could signal an impending thermal runaway, and the machine can alert the operator to take immediate action, such as disconnecting the battery or activating a cooling mechanism.
• Enhanced Automotive Battery Quality and Safety Assurance
  • Through comprehensive testing with the Battery Inner Short Circuit Testing Machine, automotive battery manufacturers can significantly improve the quality and safety of their products. By identifying and addressing potential short circuit issues early in the production process, they can reduce the number of defective batteries that reach the market. This not only enhances customer satisfaction but also helps in building a reputation for reliability and safety. For example, a manufacturer that regularly tests its batteries and takes corrective actions based on the test results is more likely to produce batteries that meet or exceed industry safety standards, such as those set by the United Nations Economic Commission for Europe (UNECE) and national regulatory bodies. In the long run, this can lead to increased market share and a competitive advantage.
  • The machine also serves as a valuable tool for automotive research and development. By studying the behavior of batteries under different stress conditions and internal short circuit scenarios, researchers can develop new materials and designs that are more resistant to short circuits. For instance, they can explore new separator materials that can prevent the electrodes from coming into contact even under extreme conditions, or develop battery architectures that minimize the risk of internal short circuits, such as modular designs with enhanced safety features.
