From May 15 to 17, 2025, the 17th China International Battery Fair (CIBF2025) was grandly held at the Shenzhen World Exhibition & Convention Center. With the theme “Linking the World · Empowering Green · Driving the Future”, the event attracted over 3,200 leading enterprises from the global new energy industry and more than 400,000 professional visitors from home and abroad, making it an unprecedented gathering.
As a full-scenario energy solution provider specializing in digital software control and high-frequency power electronics, Xi'an Topology Electric Power Co., Ltd. (hereinafter referred to as “TEP”) made a strong appearance at the event with a range of flagship products and solutions. The company showcased its latest innovations in lithium battery formation/testing and energy storage applications, drawing significant attention and widespread recognition across the industry.
TEP’s lithium battery formation and testing products now cover the entire chain from cells and modules to battery packs. In the energy storage field, the company has developed solutions for portable, residential, and commercial & industrial scenarios, forming a technologically advanced and widely applicable product matrix. At this exhibition, Tuwei focused on four major product categories:
01
Bidirectional Power Supply for Lithium Battery Formation and Testing
This product line enables bidirectional energy flow within formation and testing systems, allowing discharge energy to be fed back into the grid, significantly reducing heat generation and energy consumption while greatly improving system efficiency. Featuring high precision, fast response, and robust reliability, it is an ideal choice for high-efficiency and energy-saving applications.
02
Residential Energy Storage Battery Management Unit (BMU)
This series integrates a bidirectional DC/DC converter and battery management system (BMS), boosting low-voltage battery modules to high-voltage bus levels and allowing direct parallel connection on the high-voltage side. It is compatible with mainstream high-voltage hybrid inverters and is suitable for dynamic electricity pricing, solar + storage + EV charging, solar + storage + heating, and VPP (Virtual Power Plant) applications. Designed to address real user pain points, it offers an ideal residential energy storage solution.
03
Commercial and Industrial Energy Storage PCS
Supporting both grid-connected and off-grid modes, this PCS is compatible with 280Ah/314Ah/320Ah large-capacity battery cells. It features comprehensive protection functions and can be paired with STS for seamless grid/off-grid switching. With reliability, energy efficiency, and compact design, it empowers the rapid development of C&I energy storage.
04
Portable Bidirectional Converter & System
The Power Guardian series is a compact, highly integrated, and cost-effective off-grid energy storage system for outdoor and household use. It includes a high-power inverter, grid & MPPT charging, and UPS functionality, and utilizes 314Ah industrial-grade, long-cycle life cells to deliver a superior user experience.
CIBF 2025 served not only as a platform for TEP to showcase its core technological strengths but also as a valuable opportunity to engage and collaborate with global clients. Looking ahead, TEP will continue to advance its expertise in bidirectional energy conversion technology, explore diverse energy storage applications, and deliver efficient, reliable, and green power solutions to customers worldwide, contributing to the high-quality development of the energy storage industry.
