New energy technology breakthrough! CATL launches high-efficiency zero-auxiliary source optical storage integration system

According to news on May 24, CATL released the world’s first zero-auxiliary source light and storage integration solution at today’s SNEC Photovoltaic Conference and (Shanghai) Exhibition. This solution realizes the real-time linkage of light and storage through the innovative application of self-developed light-storage converters, high-temperature battery technology and self-heating technology, getting rid of the dependence of traditional energy storage solutions on cooling systems and auxiliary power supplies. The charging and discharging efficiency is greatly improved, and the power control response speed reaches millisecond level.

In order to combat climate change and achieve decarbonization goals, the world is working hard to increase the proportion of renewable energy use. However, despite the strong development momentum of photovoltaic energy, its stability is still limited by weather conditions, while traditional photovoltaic storage systems have problems such as low operating efficiency and complex operation and maintenance. In order to solve these problems, CATL has innovatively launched a zero-auxiliary source photovoltaic and storage integration solution. The solution consists of three modules: photovoltaic components, energy storage cabinets and photovoltaic storage converters. It achieves efficient cooperation and coordinated operation and helps the power grid to proactively Implementation of functions such as support, power fluctuation suppression, and peak shaving.

According to the editor’s understanding, in CATL’s zero-auxiliary source optical storage integration system, each string optical storage converter is equipped with an independent local energy management system (Local energy management system). EMS), and can realize real-time communication with the upper management system to achieve more intelligent energy storage operation. The photovoltaic-storage converter regulates the photovoltaic components through the energy storage battery, forming a self-contained system that is responsible for the "profit and loss" and realizes the coordinated operation of photovoltaic and storage. In addition, the system can also analyze light intensity and working scenarios in real time, identify photovoltaic and energy storage energy distribution needs in different environments, adapt to maximum efficiency under changing weather conditions, achieve "zero" deviation in output power, and respond at the millisecond level.

After three years of research and development, CATL has innovated in the entire chain of materials, cells and products, and built an integrated zero-auxiliary source optical storage integration solution The solution has greatly improved the operational efficiency, response speed, service life, durability and safety of the energy storage system, and achieved significant ecological and economic benefits. As the world's leading new energy innovation technology company, CATL is committed to providing customers with excellent quality, outstanding performance and positive results, setting a benchmark for the establishment of new power systems around the world, fully unleashing the potential of renewable energy, and providing It has made outstanding contributions to global clean energy transition and sustainable development.
