Yishengda cylindrical battery cell capacity dividing equipment
Choosing a cylindrical battery cell distribution cabinet that suits your needs requires comprehensive consideration of multiple factors. Here are some suggestions:
1. Capacity parameters:
Voltage range: Ensure that the output voltage range of the capacitor cabinet can cover the working voltage range of the cylindrical battery cells you are using. For example, if the common 18650 battery cell has a nominal voltage of 3.7V, the voltage output of the capacitor cabinet should at least include this voltage value and leave a certain margin to adapt to the differences in characteristics of different battery cells.
Current capability: Select the appropriate current output capacity of the capacitor cabinet based on the capacity of the battery cell and the requirements for charging and discharging rates. If your battery cell requires fast charging or high current discharge testing, the capacity divider should have the corresponding high current output capability, generally measured in amperes (A).
2. Accuracy requirements:
Voltage accuracy: High precision voltage measurement is crucial for accurately evaluating the performance and capacity of battery cells. Generally, the higher the accuracy of voltage measurement, the better. For example, a voltage divider cabinet with accuracy better than one thousandth or even higher can more accurately reflect the actual voltage situation of the battery cell and help screen out battery cells with consistent performance.
Current accuracy: Similarly, current accuracy also affects the control and capacity calculation of battery cell charging and discharging processes. High precision current sensors can provide more accurate current measurement values, typically achieving an accuracy of around one thousandth.
3. Number of channels:
Production scale and efficiency: If you are engaged in large-scale production and need to conduct capacity testing on a large number of battery cells simultaneously, you should choose a capacity distribution cabinet with a large number of channels, such as equipment with dozens or even hundreds of channels, which can greatly improve capacity distribution efficiency and meet production needs.
Flexibility and Cost: Distribution cabinets with fewer channels may have relatively lower prices. For small-scale production or early-stage research and development, there is no need to handle a large number of cells at the same time. Choosing a distribution cabinet with a moderate number of channels can reduce costs while meeting demand, and it is also more flexible in use, gradually expanding according to actual needs.
4. Compatibility:
Cell model: Confirm if the distribution cabinet is compatible with the cylindrical cell model you are using, such as 18650, 21700, 32650, etc. Some distribution cabinets may only be suitable for specific models of battery cells, while others have wider compatibility and can support a variety of cylindrical battery cells of different specifications.
Other equipment: If there are other related devices on your production line, such as battery automatic sorting machines, battery spot welding machines, battery comprehensive testers, etc., you need to consider the interface and communication compatibility between the capacity distribution cabinet and these devices in order to achieve smooth connection and data sharing throughout the entire production process.
5. Operation and Control:
Human machine interface: Choose a capacity divider with a friendly and intuitive human-machine interface, which is easy to operate, set capacity parameters, view test data, and monitor the capacity division process. Clear display screens and convenient operation buttons or touch screens can improve work efficiency and reduce operational errors.
Automation level: Determine the required level of automation based on your production needs. Some distribution cabinets have automated testing processes, including automatic charging, discharging, data recording, and result analysis functions, which can reduce manual intervention and improve the consistency and accuracy of testing; For some research and development or special testing scenarios, more flexible manual control functions may be required.
Data management: A good data management system is crucial for capacity partitioning work. The capacity divider should be able to accurately record and store the capacity data of each battery cell, including voltage, current, capacity, internal resistance, and other information, and have data export, query, and analysis functions for subsequent quality traceability and data analysis.
6. Quality and reliability:
Brand and reputation: Choosing a well-known brand and a well reputed container manufacturer can ensure product quality and reliability to a certain extent. Understanding the manufacturer's market reputation, product quality records, and customer evaluations can help select equipment with better quality assurance.
Equipment stability: The capacity distribution cabinet needs to operate stably for a long time to ensure the accuracy and consistency of the capacity distribution results. Understand the stability indicators of the equipment, such as the failure rate during long-term operation, heat dissipation performance, etc. In addition, some distribution cabinets may have safety protection functions such as overload protection, overvoltage protection, and overcurrent protection, which can effectively protect the safety of battery cells and equipment itself.
After sales service: Comprehensive after-sales service is an important guarantee for the normal operation of equipment. Understand the manufacturer's after-sales service system, including after-sales response speed, maintenance cycle, technical support, and other aspects. Before purchasing, you can communicate with the manufacturer or supplier about the specific content and commitments of after-sales service to ensure that any problems encountered during use can be resolved in a timely manner.
7. Cost budget:
Equipment price: Based on your budget range, choose a cost-effective container that meets your capacity requirements. Don't just pursue low prices and ignore the performance and quality of the equipment; There is no need to blindly pursue high-end equipment and cause unnecessary cost waste.
Operating costs: In addition to the price of the equipment itself, it is also necessary to consider the operating costs of the equipment, such as power consumption, maintenance costs, etc. Some efficient and energy-saving capacity sharing cabinets may save energy costs in long-term use; Meanwhile, equipment that is easy to maintain and upkeep can reduce maintenance costs and downtime.
