BTS8-3 is eight channels battery test system for Li-ion, LiFePO3, Ni-MH, Ni-Cd and lead acid batteries up to 5V@3A. This system provides most applications in battery testing fields such as electrode materials research, battery performance test, small-scale battery formation, capability grading, battery pack testing, etc.
According to the international standard design, each channel of the system has an independent constant-current source and a hardware constant-voltage source. Constant-current source and constant-voltage source can be programmed and controlled as desired. In addition, an independent pulse source is added to each battery channel to meet with the requirements of dynamic internal resistance measurement.
BTA8-3 adopts module construction. With plug-and-play design, the user can freely remove and load the module units under a nonstop status without interrupting other module unit's normal running. This function is convenient for the system's maintenance.
Performance
Each module provides 8 independent programmable channels. With built-in power supply, and complete controllable circuit, each module can work independently. Each channel can set different working modes. Channels are completely independent.
Fine programming characteristic. The system software (TC51) can set working steps and working parameters, working modes of each step flexibly. Working modes includes constant current discharge, constant current charge, constant voltage charge, rest, GOTO, (internal resistance measurement). Each working modes can set voltage, current, time, capability, negative voltage slope, and other limit conditions. When the present limit conditions are met, the system will continue next working mode automatically. The set program can be saved and opened in the form of Schedule.
Complete controllability. The system software has GOTO, restart and resume functions which allow the user to change the working parameters at any time.
Windows-based software interface, Stable performance, and easy operation. The system's software is easy to operate. With real-time monitoring windows and integrated graph/data windows, the testing process can be observed more directly and efficiently. During the test, the software will give timely instructions and warnings, provide intelligent help both in English and Chinese.
Powerful data and graph processing function. The software of BTA8 Battery Testing System adopts standard SQL data-base management, and is compatible with Access, Excel. It features large data processing capacity. The user can define the curve coordinate himself such as voltage-time curve, current-time curve, capacity-voltage curve, loop times-charge/discharge capacity curve, loop times-charge/ discharge efficiency curve, etc.
Advanced and easy-to-use battery grading function. According to the battery's capacity, internal resistance and charge/discharge platform, the Battery Testing System series can grade the batteries. After the user set the standards of separation, the system will analyze the test result data automatically, confirm the consistency indicators for the batteries under test and provide a test result report. At the same time, the LED on the channel will indicate the physical location of the batteries with the same grade.
Complete test process record (log function). BTS8-3 Battery Testing System series can make a complete record of all the events happened in the test. During the process of test, some accidental events such as power failure, system shut down, erroneous communication, erroneous operation and forced operation and so on will lead to sudden changes of the test data (sudden changes of the voltage or current). By checking the record, user can more easily find these external interferential causes.
Intelligent power failure protection. In the event of power failure in the process of test, the testing system will automatically shutdown preset running channels. And when the power failure has recovered, the system will automatically resume those stopped channels and ensure that the test is normally conducted and the date will never lose at any cases.
Specially made battery holders. BTS8-3 Battery Testing System provides two types of battery holders - alligator flips with cable and spring load holder wit adjustable length to allow you measure flat or cylinder battery at easy.
4-electrode measuring. All the battery fixtures have 4 electrodes, including 2 current ends and 2 voltage measuring ends. Multi-electrode measurement improves measuring accuracy.
Channel can be inputted impedance up to 10 Mohm. Any battery channel of BTS8-3 Battery Testing System has more than 10 MOhm input impedance and its current leakage is less than 0.5 micron A. This feature ensures the reliability of the test result and provides good guarantee for the micro-current measurement.
Precision current: The system provides -3A - +3A current output range at 0.1 % accuracy ( to achieve the accuracy, ...
