Regenerative Battery Tester for Data Centre
Precision charge/discharge simulation for battery packs with up to 70% energy feedback to the grid.
Designed for ESS testing, UPS commissioning, and industrial battery applications - fully compliant with IEC/GB grid standards.
What It Does - Regenerative Battery Tester
Regenerative battery tester is a high-precision testing solution that simulates real-world battery charge and discharge conditions while feeding up to 70% of test energy back to the power grid. Ideal for ESS, UPS and industrial battery testing, it fully complies with IEC and GB standards.
Unlike dissipative testing systems that convert all energy to heat, regenerative testers return power to the grid. No massive cooling systems needed - lower ambient temperatures, less noise.
Supports CC/CV/CP/CR/dynamic modes across a wide DC voltage range of 100V-800V. Covers ESS pack testing, UPS battery commissioning, energy storage system validation, and industrial battery applications.
AC/DC Rectification
The PLC / control unit regulates the current drawn from the DC bus based on your configured load parameters (e.g., 100kW constant power, 0.8 lagging power factor). By precisely controlling absorbed current, the tester simulates the exact load characteristics — resistive, inductive, or capacitive — that the unit would see with a real IT load.
DC Bus Regulation & Load Simulation
The PLC / control unit regulates the current drawn from the DC bus based on your configured load parameters. By precisely controlling absorbed current, the tester simulates exact load characteristics.
DC Bus Stabilization & Filtering
The rectified DC power passes through bus capacitors for voltage stabilization and inductors for filtering - producing clean, stable DC voltage ready for the final inversion stage.
DC/AC Grid Feedback
The internal grid-tied inverter (DC/AC) converts the stable DC power back into AC at the same frequency, phase, and voltage level as the grid - and feeds it back into the facility's distribution system.
Key Features of the Regenerative Battery Tester
High-Efficiency Energy Feedback
High-efficiency energy feedback via bidirectional AC-DC-AC conversion - up to 70% of absorbed test energy is recycled back to the grid, significantly reducing electricity costs and enabling green, sustainable testing.
Minimal Heat, Data-Centre Friendly
Minimal heat generation eliminates the need for high-capacity cooling systems or large air-conditioning loads. Does not raise ambient temperature - ideal for temperature-sensitive environments like data centres, labs, and clean rooms.
Precision Four-Quadrant Load Simulation
Precision four-quadrant load simulation with constant power/current/voltage modes, supporting RLC, harmonic, and transient load conditions. Four-quadrant operation perfectly covers full-condition testing for ESS PCS and UPS equipment.
Safe Grid Connection & Compliance
Built-in grid synchronization, over-voltage/over-current, and anti-islanding protection mechanisms. High power factor and low harmonic distortion on feedback power.

Common Question
What DC voltage range does the tester support?
Standard units cover 100V to 800V DC. Extended voltage ranges are available on request for specific battery pack configurations. Please share your battery pack specifications and we will confirm the compatible configuration.
What power ratings are available?
Standard models range from 50kW to 500kW per unit. For higher power requirements, multiple units can be paralleled for cluster control up to 1MW+. Please specify your power and voltage requirements for a tailored quotation.
Can the feedback efficiency really reach 70%?
Yes — at full load under standard grid conditions, measured feedback efficiency reaches 65–70%. Actual values vary slightly by power range, load type, and grid conditions. We confirm all performance data at factory acceptance test before shipment.
What applications are supported?
The tester supports applications include ESS validation, UPS commissioning, EV battery pack testing, BMS integration, and cycle life testing.
How is the unit controlled on site?
The unit supports three control methods: TCP/IP for remote multi-unit management, Modbus RTU for local parallel operation, and direct PC connection for on-site monitoring and control.
Can multiple units be run together for larger ESS projects?
Yes. Multiple units can run in parallel on a TCP/IP network, enabling one control interface to manage total power up to 1MW or beyond. Cluster control software supports synchronized charge/discharge across all units.
