BTS8-10 is an eight channels battery testing system for Li-Ion, LiFePO4, NiMH, NiCd cells or battery packs up to 10A 30V per channel. 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 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.

• Fine programming characteristic. The system software can set working steps and working parameters, working modes of each step flexibly. Working modes includes constant discharge current, constant charge current, constant charge voltage, rest, GOTO, (internal resistance measurement). Each working mode can set voltage, current, time, capability, negative voltage slope, and other limit conditions, the relation of which is logic. 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 cordinate 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 Neware 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). BTA8-10 Battery Testing System series can make a complete record of all the events happened during 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 flips. BTS8-10 Battery Testing System series provides many types of battery flips. The relative separation of the flips and the machine as well as the software and hardware self-protection of the system (over voltage, over current, etc) increase the safety of the system greatly and ensure the user's carefree test.
  General-purpose (4 leads) flips: This type is designed under the proposal of the experts and to meet the requirement of mass production. It is applicable to fix various types of cylinder and square batteries. This type is reliable, durable and easy to maintain.
  Flips for R&D use: This type can lead out all the charge/discharge electrodes and measuring electrodes by using alligator flips and facilitate the fixing of any type of abnormal-shaped batteries or battery groups.

• 4-electrode measuring. All the battery fixtures on each channel have 4 electrodes, including 2 current ends and 2 voltage measuring ends. Multi-electrode measurement improves measuring accuracy.

• Channel can input impedance up to 10 Mohm. Any battery channel of BTS8 Battery Testing System has upto 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.

• High reliability. Standard production follows the procedures of ISO9001; Aging test on randomly selected samples prior to delivery of products;
  Independent protection circuit in every channel to prevent over current and over voltage; Upper and lower dual software protection.

• Precision current: Normally, the 1 system provides -3A - +3A current output range. For the customers engaged in material research, we can provide the battery test system of 5mA, 10mA test range at optional and the minimum current can be up to 0.01mA (see related product below)

• Voltage Input: Please choose 110V AC or 220 - 240V AC in product option
