Equipment introduction

BTS-5V3AS1 is a precision eight-channel high-precision battery test system. This system is the best tool for researching new generation energy storage materials and rechargeable batteries. Designed in accordance with international standards, each channel system has an independent constant current source and constant voltage. Constant current source and constant voltage source can be programmed and controlled according to the scheme. In addition, each channel has an independent signal source to meet the dynamic requirements of internal resistance measurement.

Each module provides eight independent programmable channels: built-in power supply and complete control circuit, each module can work independently. Each channel can be set with different working modes; precise programming features: the system software can set ± working steps and working parameters, and the flexibility of the working mode at each step. Working modes include constant current discharge, constant current charge, constant voltage charge, and rest. Each working mode can set voltage, current, time, power, negative voltage gradient, and other restrictions. When the current restrictions are met, the system will automatically continue to the next working mode. The set program can be saved and opened according to the schedule; complete controllability: the system software has GOTO, restart and recovery functions, allowing users to change working parameters at any time. Windows-based software interface, stable performance and easy to operate. The software operation of the system is simple. Real-time monitoring of the computer interface comprehensive graph/data window can more directly and effectively observe the test process. During the test, the software will provide timely instructions and warnings, and provide intelligent help in English and Chinese.
