In 2025, driven by favorable policies, technological breakthroughs, and capital influx, the North American energy storage market is accelerating its expansion. From Tesla to CATL, global energy giants are betting on this trillion-dollar blue ocean. Facing the North American market with unlimited potential, Chinese energy storage companies are facing unprecedented opportunities and severe challenges. From localized adaptive adjustments to the docking of technical standards, every step is a test for the company.
The 15th China International Energy Storage Conference and Exhibition (CIES 2025) will be held at the Hangzhou International Expo Center from March 23 to 26. As an annual event in the energy storage industry, CIES brings together elite companies, experts and scholars in the global energy storage field to discuss the latest development trends and market opportunities of energy storage technology.
As a provider of electricity measurement solutions, Shenzhen Hangzhi Precision Electronics Co., Ltd. will exhibit products such as energy storage high-precision fluxgate current sensors, energy storage BMS current sensors, and high-precision AC and DC testers at CIES 2025.
In energy storage systems, especially energy storage power conversion systems (PCS) and battery management systems (BMS), accurate current monitoring is the basis for ensuring efficient, stable and safe operation of the system. As a key current sampling and control device for energy storage, current sensors play a vital role. Compared with traditional Hall current sensors, choosing Hangzhi’s 0.05% high-precision fluxgate current sensor can increase the steady-state current accuracy of PCS from the original ±2% to ±0.1%, and the accuracy is improved by 2 orders of magnitude, thereby increasing the charging and discharging capacity of the equipment by 4%, and improving the economy by 2%, bringing higher returns to investors.
