Product Equipment System Principle
The aging cabinet system utilizes AC 380V power input, processes through the circuit with a power factor of ≥99% and realizes independent voltage and current sampling through four-wire connection. During the test, the energy feedback system returns discharged energy back to the power grid with an efficiency of ≥90% in order to save energy consumption. The system real-time monitors battery temperature through NTC sensors, combines closed loop control systems, combining voltage, current, and battery temperature for real-time testing and monitoring, and supports 2000 step programming and 65535 Cycle Nesting. The hardware is equipped with multiple protection mechanisms, and the software performs data interaction based on TCP/IP protocol which can real-time calculate DC internal resistance. With step logic jumping,global parameter configuration, and complete programming, the aging cabinet accurately completes cell performance grading and aging tests.
