5V 100A 48CHS Regenerative Lithium Battery Cell Capacity Grading Testing Machine

The ACEY-BCT5100-48P prismatic lithium battery cell testing machine is a high-precision battery testing system featuring independent 2-channel programmable CC/CV sources and a four-wire interface for maximum accuracy. Controlled by an STM32 MCU, it offers a user-friendly graphical interface for real-time monitoring, data logging, and sorting, with a specialized FET-based design optimized for low-voltage discharge (e.g., LiFePO4). The system ensures high reliability through its modular architecture, power-off memory, and comprehensive abnormality protection, making it a robust and easy-to-maintain solution for professional battery capacity grading.

• The equipment is connected to and controlled by a computer to send instructions and collect data.
• The keyboard allows manual operation of the equipment and displays parameters and status.
• The constant current board is controlled by the CPU and provides constant current and constant voltage functions.
• During battery charging, the bidirectional power supply converts AC power into 14V DC power, and battery charging control and detection are realized through the constant current board.
• During battery discharging, the process is reversed: the battery voltage is first boosted to 15V through the constant current board, and then the DC power is converted into AC power through the bidirectional power supply and fed directly into the factory's AC distribution network, thereby realizing energy feedback from the battery discharge power.
