Smart Manufacturing New Arrival | Racing Ahead in the Energy Storage Track: CEEG Adds Another Multi-Voltage High-Power Transformer (+1)

Recently, CEEG successfully rolled off the production line the multi-voltage high-power transformer for its energy storage system test platform. This latest addition to the energy storage technology portfolio marks another major breakthrough for CEEG in smart new-energy manufacturing!

R&D Background

The Guiding Opinions on Accelerating the Development of New Energy Storage clearly state that energy storage is a vital equipment foundation and key supporting technology for achieving China's "carbon peaking and carbon neutrality" goals and safeguarding national energy security.

As sustainable and clean energy development deepens, energy storage systems are being applied in an increasingly diverse range of scenarios, and microgrid systems are evolving toward greater variety. However, due to the instability of renewable sources such as photovoltaic and wind power and the volatility of their loads, a system relying solely on photovoltaic, wind, and fuel generators can easily fall out of balance. In particular, when renewable power output exceeds load demand, the system may face the risk of failure.

By contrast, energy storage converters, with their flexible energy absorption and release capabilities and fast response characteristics, can effectively balance the flow of energy within the system. As a result, energy storage converters are increasingly becoming a core element in ensuring the stable operation of microgrid systems.

Product Highlights

The expertly crafted multi-voltage high-power transformer for the energy storage system test platform has passed the rigorous testing of a third-party inspection agency on the first attempt and successfully rolled off the production line. The product meets the differentiated voltage-level requirements of different energy storage systems, and to a considerable extent addresses the shortcomings of conventional test power supply schemes in terms of investment cost, space requirements, and ease of use, breaking through a bottleneck in the development of the energy storage industry.

High power, multiple secondary voltage combinations, and high voltage precision enable precise matching with energy storage systems of different voltage requirements

All key performance indicators exceed the requirements of relevant standards 

Low losses and clear energy savings provide users with efficient, reliable test power supply solutions

Outstanding anti-harmonic, high-overload, and high-overvoltage performance ensures the stability and reliability of the power supply, providing strong support for the safe and efficient operation of the test platform

Proven Capability

Upholding its core values of "Vision, Innovation, Responsibility," CEEG firmly grasps the historic opportunities presented by "carbon peaking and carbon neutrality" and the construction of the new-type power system. With deep technological accumulation and a spirit of innovation, the company injects surging momentum and fresh vitality into the transformation and development of the energy storage market.
