Summarize.

Solar energy storage charging and detection system, the system is divided into battery cabinet, power cabinet (power conversion) and charging terminal. Power cabinet and battery cabinet are standardized cabinets; photovoltaic access, maximize the use of clean energy power supply; use of universal DC bus program; power cabinet modular design, support for multiple modules in parallel, easy to maintain; charging and detection, the use of electric vehicles or battery packs discharged, detecting the battery capacity, calculating the extent of the battery capacity degradation; increase the energy storage system, reduce the initial investment, improve the reliability of the power supply, and resolve some of the Grid expansion problems, alleviate the impact on the regional power grid; electric vehicles can be both charged and discharged, realizing the two-way interaction between electric vehicles and the grid, and realizing peak shaving and valley filling.
