Solar energy storage power station debut for battery management system certification

On July 10, energy storage alliance electrochemical energy storage unit, vice director of sun power was awarded the first power station with a battery management system ( BMS) Authentication certificate. At this point, the sun power became the first complete, module, battery cluster from the battery to the battery management system four one certification of enterprises.

BMS is energy storage battery of the brain and central nervous system, its degree of advanced, reliable, solar energy equipment, solar panels, the battery can get longer life, more safety running plays a key role. According to GB/T34131 - Electrochemical energy storage power station in 2017 'technical specification for lithium ion battery management system and CGC GF - 176 - 2020 a 'electrochemical energy storage system with complementary technology battery management system requirements, the evaluation scale certification center of the sun power BMS environment adaptability, voltage, current, temperature monitoring, data acquisition precision and safety comprehensive assessment, etc.

results show that the solar panels, sun power independent research and development of BMS, fully meet the requirements of two standard test data. SOC ( SOE） Estimate accuracy calculation accuracy and precision of electric current, the electric energy is far superior to GB/T34131 - key indicators Limit in 2017, is the industry leading level. Plus the battery monomer, module, battery certification of the clusters, the sunlight power battery system has been formed from the full range of equipment to the system level certification.

at present, around the system security and life of two key problems, photovoltaic (pv) grid, the power energy storage system USES a & other; Battery level management, level 4 fusing and millisecond linkage protection & throughout; Safety design, formed from the battery monomer, modules, batteries, battery management system to the PCS cluster all-round protection system.

in recent years, our country energy storage size has maintained rapid growth, how to balance security premise, solar energy, raise the overall performance of the battery, guarantee the safe and stable operation of power station, has become the industry faces an important subject. For a long time, the sun always adhere to the power supply from the parts to the comprehensive coordination and linkage system level, to ensure the safety of the energy storage system is reliable. As of the first half of 2020, sun power energy storage system has been applied in global 1000 + major energy storage project, not a security incident.
