FH Series Regenerative Charging and Discharging Equipment

The H Series Regenerative Charging and Discharging System is designed for large-scale battery maintenance in EV factories, 4S stores, and battery storage facilities. This advanced system supports high-power lithium battery packs across a wide voltage range, ensuring safe and efficient charging and discharging. Utilizing regenerative discharge technology, it prevents additional heat generation, making the testing process both energy-efficient and environmentally friendly.

Key Features and Advantages:

• Bidirectional Energy Feedback – The system ensures energy can flow in both directions, automatically adjusting the energy transfer process. During battery maintenance, excess energy is fed back to the three-phase power grid, achieving a DC bus efficiency of ≥93%, significantly reducing power consumption and cooling costs.

• High-Power Isolation Transformer – The entire system is electrically isolated from the grid, ensuring fast current conversion without overshoot, enhancing stability and reliability.

• Advanced DC/AC Module – Implements space vector modulation technology, increasing voltage utilization and minimizing current harmonics for optimal performance.

• PID-Controlled DC/DC Module – Incorporates multi-layer protection mechanisms, ensuring stable operation even under complex working conditions.

• External Communication & Control – Seamlessly integrates with external fixtures to receive and execute operational commands for automated testing and control.

• CCCV Charging Technology – Ensures a smooth charging process without voltage or current surges, preventing issues like island effect, micro-short circuits, or PCB protection failures caused by peak current accumulation.

• High-Precision ADC/DAC – Features a wide dynamic range and high sampling accuracy, ensuring long-term voltage measurement stability.

• DCIR Impedance Testing – Conducts real-time load impedance analysis within milliseconds, accurately detecting unstable battery cells and identifying potential performance issues.

• Voltage Clamping Protection – During charging, voltage can be clamped at a predefined level to prevent damage to the battery management system (BMS) or protection boards in case of faults.

• ECD & EVD Battery Protection – Automatically identifies and isolates faulty or non-compliant battery cells, preventing unsafe charging or discharging operations.

This high-efficiency lithium battery maintenance system is a must-have for large-scale battery facilities, providing intelligent battery diagnostics, advanced energy recovery, and optimized power management for maximum safety and cost savings.
