Billion liter capacity distribution cabinet
Choosing a battery compartment that suits oneself requires comprehensive consideration of multiple factors. Here are some suggestions:
Battery type: Different types of batteries (such as lithium-ion batteries, lithium polymer batteries, nickel hydrogen batteries, nickel cadmium batteries, etc.) may have different requirements for the capacity distribution cabinet. It is necessary to ensure that the capacity distribution cabinet is suitable for the type of battery being tested.
Number of channels: determined based on your production or testing scale. If a large number of batteries need to be tested simultaneously, choose a capacity divider with multiple channels, such as 96ch, 128ch, 512ch, etc; If the number of tests is small and the number of channels is small, a distribution cabinet with fewer channels may be more suitable, which can also save costs and space. For example, small battery production workshops may choose containers with fewer channels, while large battery production enterprises may require distribution cabinets with 512 or even more channels.
Current and voltage range: To meet the specifications of the battery you are testing. For example, for some high-capacity and high rate batteries, a capacity divider cabinet is needed to provide a larger current and a suitable voltage range. Common models include 5V3A, 5V6A, 5V30A, 5V10A, 5V120A, etc. Ensure that the current and voltage parameters of the selected capacitor cabinet can cover the battery range you want to test.
Accuracy and precision: High precision capacity dividers can more accurately measure parameters such as battery capacity and internal resistance, which is particularly important for applications that require high battery performance, such as high-end electronic products and electric vehicle batteries. The measurement accuracy of current and voltage for chemical capacitance devices in the general market is around one thousandth, and higher precision devices (such as current and voltage sensors with a measurement accuracy of over one ten thousandth) can provide better test results.
Step setting and programmability: If your testing requires complex charging and discharging processes or specific testing procedures, then choose a divider cabinet with more step settings (such as 64 steps or more) and strong programmability. This allows for flexible setting of different charging and discharging modes, cycle times, cut-off conditions, etc., to meet various special testing needs. For example, research institutions may require this powerful capacity divider for battery performance research.
Data recording and analysis function: Good data recording and analysis function can facilitate your viewing, organization, and in-depth analysis of test results. For example, being able to record detailed data for each charging and discharging step (such as open circuit voltage, average voltage, termination voltage, termination time, termination capacity, termination power, termination current, etc.), and having the ability to transfer data, convert to Excel format, and generate various curves (such as voltage time, current time, capacity time, etc.), can help you evaluate the performance and quality of the battery.
Stability and reliability: Fractional cabinets require long-term stable operation, especially during large-scale production or long-term testing processes. Understand the hardware quality of the equipment, the quality of the components used, the heat dissipation design, and whether it has intelligent protection functions (such as overvoltage, overcurrent, overheating protection, etc.) to ensure the stability and reliability of the equipment, reduce failures and downtime.
Operating interface and usability: A simple, convenient, and intuitive capacity divider can improve work efficiency and reduce operational errors. For example, the built-in keyboard and large LCD Chinese display interface make it easier for you to set parameters and view test status.
Scalability: If you have plans to expand production or testing scale in the future, consider choosing a container with good scalability, such as one that can easily increase the number of channels or expand networking with other devices. Some capacity sharing cabinets use network connections and SQL databases to centrally control multiple connected cabinets, up to a maximum of 255. This scalability facilitates subsequent upgrades and expansions.
Brand and after-sales service: Choosing a well-known brand of container usually ensures better quality, and the brand manufacturer can generally provide more comprehensive after-sales service, including technical support, equipment maintenance, software upgrades, etc. Before purchasing, it is important to understand the brand's reputation, market share, and feedback from other users, which is crucial for long-term use and maintenance of the equipment.
Working mode: Divided into linear and energy feedback types. The energy feedback type capacity divider can convert the electricity released by the battery during the charging and discharging process back into electrical energy for charging the battery, and feed the excess electrical energy back to the factory power grid. It can achieve bidirectional energy saving, save energy consumption and electricity expenses, and is suitable for long-term large-scale battery capacity testing with energy-saving requirements; Linear type capacity distribution cabinets have a relatively simple structure and may have lower costs, making them suitable for situations where energy-saving requirements are not high or testing scales are small.
Budget: Choose a suitable distribution cabinet based on your own budget, and try to choose equipment with high cost-effectiveness while meeting testing needs. However, do not pursue low prices too much and sacrifice the quality and performance of the equipment. At the same time, the long-term usage costs of the equipment, such as energy consumption and maintenance expenses, should also be considered.
