ENERGY STORAGE SYSTEM SELECTION

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.

Solar power generation and automotive energy storage

This paper explores the concept of electric power generation from SEV shighlighting how embedded solar panels can convert sunlight into usable electrical energy for vehicle propulsion, battery charging, and even grid support through bidirectional energy systems.While current technological limitations—such as low surface area, variable solar efficiency, and high costs— pose challenges to large-scale adoption, advancements in lightweight materials, high-efficiency PV cells, and intelligent energy management systems are steadily improving SEV viability.

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.
