Integrated Battery Testing Equipment Customized For Lithium Burning Test

1. Product Name and Purpose

2. Product Features

• Integrated and Robust Design
  • The tester is constructed with a heavy-duty framework, usually made of high-strength steel, to withstand the potential stresses and hazards associated with battery testing. The exterior is designed to be durable and resistant to chemical and thermal damage. The interior is compartmentalized and lined with fireproof and heat-resistant materials to contain any potential battery failures. The control panel is strategically placed and protected, featuring a user-friendly interface with clear indicators and buttons for easy operation. The equipment also includes safety interlocks and shields to prevent accidental exposure to dangerous test conditions.
• Precision Charging and Discharging Systems
  • Charging Control: The charging system is highly accurate and programmable, capable of handling a wide range of battery voltages and chemistries. It can apply precise charging currents and voltages, following specific charging profiles such as constant current-constant voltage (CC-CV) or multi-step charging algorithms. The system monitors the battery's voltage, current, and temperature during charging to ensure safe and efficient charging. It can also detect and handle overcharging conditions, automatically adjusting the charging parameters or terminating the charge process.
  • Discharging Control: The discharging system is equally precise, allowing for controlled discharging of batteries at different rates. It can measure the battery's capacity accurately as it discharges, providing valuable data on the battery's performance. The system can also simulate real-world discharging scenarios, such as pulsed discharges or continuous discharges at varying loads. It is equipped with safety features to prevent over-discharging, which could damage the battery.
• Extreme Condition Testing Capabilities
  • Short Circuit Test: The tester can perform short circuit tests on batteries, creating a direct connection between the battery terminals. It measures the resulting current and temperature rise, evaluating the battery's ability to handle short circuit situations without overheating or exploding. The system is designed to quickly interrupt the short circuit if dangerous conditions are detected.
  • Nail Penetration Test: This feature allows for the simulation of a nail penetrating the battery. The tester records the battery's response, including any potential thermal runaway or gas evolution. It helps assess the battery's internal structure and safety mechanisms in the event of a severe internal short circuit.
  • Lithium Burning Test: The equipment can initiate a controlled lithium burning test, observing how the battery reacts and whether it can contain the reaction without spreading. This test is crucial for evaluating the battery's safety in case of a lithium-based chemical reaction going awry.
  • Drop Test: The tester is equipped with a mechanism to perform drop tests on batteries from specific heights and angles. It measures the battery's performance and integrity after the drop, checking for any damage to the casing, terminals, or internal components. The data obtained helps determine the battery's durability and reliability during transportation or accidental drops.
• Advanced Instrumentation and Data Acquisition
  • The tester is outfitted with a comprehensive suite of sensors. Voltage and current sensors are used to monitor the battery's electrical parameters during charging, discharging, and other tests. Temperature sensors are strategically placed to measure the battery's surface and internal temperature. These sensors are connected to a state-of-the-art data acquisition system that records and stores all the test data. The data can be accessed and analyzed in real-time or retrieved later for in-depth studies. The data acquisition system is highly flexible and can be integrated with battery-specific software and databases, facilitating seamless data transfer and analysis. It can also be configured to send notifications and reports automatically, saving time and effort for the users. Additionally, the control panel includes built-in alarms and safety features that alert users in case of any abnormal battery behavior, temperature spikes, or equipment malfunctions.

3. Specific Parameters

• Voltage and Current Range: The tester can handle a wide range of battery voltages, typically from a few volts for small consumer batteries to several hundred volts for high-power battery packs. The current range can also vary, accommodating low-current charging and discharging for small batteries and high-current capabilities for larger battery systems. For example, it may support charging currents from a few milliamperes to several tens of amperes and discharging currents up to hundreds of amperes, depending on the model and configuration.
• Temperature Measurement Range: The temperature sensors can measure a broad temperature range, usually from -40°C to +150°C, to accurately monitor the battery'
