Battery Inner Short Circuit Testing Machine ODM For Automotive Battery Testing

1. Product Name and Purpose

2. Product Features

• Automotive-Grade Robustness and Precision
  • The machine is constructed with a heavy-duty framework, crafted from high-strength automotive alloys, to withstand the rigors of testing large and powerful automotive batteries. The testing chamber is engineered with meticulous precision, featuring a non-conductive and heat-resistant interior lining made of advanced composites. This lining not only shields the machine's components from the intense heat and chemical byproducts of a short circuit but also ensures accurate and consistent test results. The door of the chamber is designed for an airtight and secure seal, incorporating a redundant locking mechanism and a high-temperature-resistant gasket. It also includes a large, optically clear viewing window, made of toughened and anti-reflective glass, allowing for detailed visual inspection of the battery during testing.
• Advanced Detection and Monitoring Systems for Automotive Batteries
  • Electrical Parameter Analysis: Equipped with ultra-precision voltage and current sensors, the machine can detect the slightest fluctuations in the battery's electrical characteristics. These sensors have a wide dynamic range, capable of handling the high voltages and currents typical of automotive battery systems. The resolution is fine-tuned to identify minuscule changes that could signal the onset of an internal short circuit. The data acquisition system records and analyzes these electrical parameters in real-time, generating detailed graphs and reports that pinpoint the exact moment and location of a potential short circuit.
  • Temperature Surveillance: To comprehensively assess the thermal behavior of automotive batteries during testing, the machine is outfitted with a network of temperature sensors. These sensors can measure a broad temperature spectrum, from sub-zero temperatures to over 1200°C, with an accuracy of ±0.5°C. They are strategically placed both on the surface and within the interior of the battery, providing a 3D understanding of the heat distribution. The temperature data is crucial in determining whether a short circuit is leading to a dangerous temperature rise and potential thermal runaway, allowing for timely intervention.
  • Gas Detection and Analysis: In the event of an internal short circuit, automotive batteries may release various gases, some of which could be toxic or flammable. The testing machine includes highly sensitive gas sensors that can detect and identify a wide range of gases, such as hydrogen, carbon monoxide, and volatile organic compounds. The sensitivity of these sensors is adjustable, enabling the detection of even trace amounts of gases. This feature not only helps in assessing the safety of the battery but also provides valuable insights into the chemical reactions occurring within the battery during a short circuit, aiding in the development of more stable battery chemistries.
• Controlled Stimulation and Stress Application for Automotive Scenarios
  • The machine is capable of replicating a variety of real-world stressors that automotive batteries may encounter. It can apply mechanical vibrations similar to those experienced during vehicle operation, with the vibration frequency and amplitude precisely adjustable. The frequency can range from a few hertz to several thousand hertz, and the amplitude from a fraction of a millimeter to several millimeters, allowing for the simulation of different driving conditions. Additionally, it can subject the battery to rapid temperature changes, mimicking the thermal stresses of extreme climates or high-power charging and discharging cycles. The rate of temperature change can be adjusted, typically from a few degrees Celsius per minute to hundreds of degrees Celsius per minute. It can also apply electrical pulses or overcharge conditions in a controlled manner, simulating abnormal operating scenarios that could lead to internal short circuits, such as a faulty charging system or a sudden power surge.
• Intuitive Control and Data Management Interface for Automotive Testing
  • The control panel of the testing machine is designed with automotive engineers and technicians in mind. It features a user-friendly touchscreen interface that allows for easy setup of test parameters, such as the type and intensity of stress to be applied, the duration of the test, and the sampling rate for data acquisition. The interface also provides real-time feedback on the test progress, displaying the current values of electrical parameters, temperature, and gas concentrations. The data management system is highly efficient, automatically storing all test data in a secure and organized manner. The data can be easily retrieved, sorted, and analyzed
