Why use a battery tester?
With the rapid development of social economy, secondary batteries are efficient, clean and pollution-free, and lithium-ion batteries have obvious advantages in cycle life, energy density, power density and environmentally friendly performance. Therefore, lithium-ion batteries are widely used in various fields such as electronic products. During the production process of lithium batteries, the cells need to be formed and divided to ensure the quality and quality of the final power supply product.
Why do we use a Battery Charging Discharging Tester? What does it do?
1. By dividing the battery capacity, the capacity and performance of the battery can be quickly and accurately evaluated, helping users make choices and improving battery efficiency and lifespan.
2. Volume separation is not only beneficial to the stability of the SEI film, but also shortens the time consumed in the volume separation process, reduces energy consumption and increases production capacity.
3. Divide the cells that will be used for lithium battery assembly into mechanical parts again. Through this process, you can always pick out some cells that do not meet the requirements and return them to the cell factory. After passing the lithium battery detection mechanical test, it can be seen that the battery core has been charged and discharged and is "charged". So when you get the battery, it has two bars of electricity, which is normal.
4. Capacity classification can classify and group batteries, and select monomers with the same internal resistance and capacity for combination. When combined, only those with very similar performance can form a battery pack.
Function: Battery Charge Discharge Test System can set the charging and discharging voltage, current, power, etc. According to the set charging and discharging parameters, the device can set the frequency to collect various parameters in the current battery charging and discharging process according to certain requirements, such as recording the current battery once every second. Battery voltage, current, capacity, energy, internal resistance, temperature and other data. After setting the charge and discharge process, the battery capacity performance is reflected based on the data accumulation value, charge and discharge curve, etc., and the standards are set to screen the batteries.
