PERSONAL DEVELOPMENT OF ENERGY STORAGE PROJECTS
Enhance safety management of energy storage industry projects
Challenges for any large energy storage system installation, use and maintenance include training in the area of battery fire safety which includes the need to understand basic battery chemistry, safety limits, maintenance, off-nominal behavior, fire and smoke characteristics, fire fighting techniques, stranded energy, de-energizing batteries for safety, and safely disposing battery after its life or after an incident.

Multiple energy storage projects landed
These include the signing and landing of the 20 GWh sodium-ion battery project in Suining, Sichuan; the Jinlongyu solid-state battery materials project in Huizhou entering the approval stage; the rapid construction of the 4 GWh lithium battery project by Hubei Yijia Tong Technology Co., Ltd. in Hubei; and the steady advancement of Gaiya New Energy’s 3 GWh large cylindrical lithium (sodium) battery base in Zhejiang.

New energy storage field enters scale
On September 12, the National Development and Reform Commission and the National Energy Administration released the “ New Energy Storage Scale Development Action Plan (2025-2027)”, which clearly proposes that by 2027, new energy storage will basically achieve scale and market-oriented development, with technological innovation and equipment manufacturing capabilities remaining at the forefront globally.

Common topologies of energy storage power supplies
Most popular topologies in this regard include the Dual Active Bridge with Extended Phase Shift (for example in TIDA-010054) which deals with a primary voltage of 700V to 800V DC, and secondary voltage of 350V to 500V DC (single-phase-shift SPS) or 250V to 500V (extended-phase-shift EPS) for power levels up to 10 kW, Phase-shifted Full-Bridge (for example in PMP22951) which deals with a voltage of 400V down to 54V and a power level of 3kW or CLLLC Dual-Active Bridge (for example in TIDM-02002) which deals with a primary voltage range of 380–600V to a secondary voltage range of 280–450V and power levels up to 6.6kW.
