discharge testing of batteries

The Energy Recovery and Sorting Cabinet is an advanced Lithium Ion Battery Tester, principally used to monitor parameters such as voltage and capacity at the sorting stage of testing. The Energy Recovery and Sorting Cabinet powers each battery from an independent constant current and constant voltage source, thus ensuring test power is stable and non-impulsive in order to maintain the testing accuracy and validity of batteries being tested and sorted. The device is controlled with an STM32 microcontroller, and data can be saved onto a computer when connected, as well as being able to conduct testing and sorting operation via keystroke sequencing. This cabinet features a four-wire test interface to ensure high measurement accuracy, as well as a power failure protection which enables the cabinet to automatically resume work after power is restored. Additionally, there is a graphical user interface (GUI) that can intuitively show the test data, including voltage, current, time, and capacity for each battery. Indicating working status and abnormal situations are presented in color. The power transistor used is a field-effect transistor in the battery testing cabinet; this is suitable for low-voltage discharge batteries such as lithium iron phosphate batteries, and improves both testing efficiency and safety. 

 

High-Precision Testing: The four-wire test interface ensures high-precision measurement accuracy. Voltage and current accuracy reaches ±(0.5‰ reading + 0.5‰FS).

Intelligent Operation and Protection: The cabinet has a power failure protection function, where the cabinet can automatically resume work upon power restoration. In addition, the cabinet also supports various protection functions such as overvoltage during charging and reverse connection protection to protect batteries, device protection and provide peace of mind.

Efficient Energy Recovery: During battery discharge, electrical energy would be fed back to the factory's AC distribution network. Hence, the Energy Recovery and Sorting cabinet not only achieves energy recovery, but also reduces energy consumption when discharging and testing batteries.

 

 

 

 

R&D and Production Testing: In the battery R&D stage, the Battery Charge Discharge Tester can accurately provide high-precision voltage and current measurements. Opposed to conventional similar products the independent channel control mode and various protection functions enable proper establishes safety of use. Each of these factors will help improve the experiments taking place and development process. 

Quality Control and Sorting: During battery production, the Li Ion Battery Capacity Tester will comprehensively test each battery and accurately sort batteries based on capacity and voltage for further testing. Powerful software functions provide detailed data logs and per battery report generated data facilitate data analysis, data for quality control understands traceability and consistency. 

Energy Saving and Cost Control: In a mass battery production testing scenario, the Lithium Ion Battery Tester provides energy recovery function for a significant deceleration of energy consumption. In addition to reducing overall energy waste, energy recovered during the discharge is fed back into the grid that ultimately lowers production costs, therefore improving economic benefits.
