With the implementation of various policies such as energy conservation and emission reduction, the market's demand for energy will further change, and the energy storage industry will advance with greater momentum. Promoting the development of the energy storage industry is an inevitable choice for the dual-carbon goal.

Energy storage is stored in energy storage devices by converting electrical energy into other forms of energy. The main forms of energy storage include physical energy storage, electrochemical energy storage and other energy storage. Energy storage is mainly used for power grid transmission and distribution and auxiliary services, grid connection of renewable energy such as photovoltaics and solar energy, distributed micro-grid and user side, etc.

The energy storage system realizes the charge and discharge of electric energy through the energy storage inverter. The energy storage system has high DC voltage, high power, and a large number of batteries. The electromagnetic interference is serious and the control is relatively complicated. In order to ensure the integrity of the energy storage system signal, reduce environmental interference, and reduce potential safety hazards, the research and development design of the entire energy storage system cable needs to consider the mutual coupling of signals and the shielding structure design.

The wiring space of energy storage cables is narrow in energy storage applications, and the cables are required to be flexible enough and have a small bending radius to meet the wiring requirements. In order to ensure good flame retardancy, the cable needs to pass a single flame retardancy test; set up a thermal life test to ensure that the cable meets the long-life requirements; due to the particularity of the application environment, it needs to be resistant to battery acid and battery electrolyte; especially for outdoor use Energy storage cables have more stringent requirements for anti-UV and anti-salt spray. In addition, energy storage cables must also meet low-smoke, halogen-free, and flame-retardant requirements.

The common materials of energy storage cables are PVC, XLPE, and silicone rubber, the common temperature grades are 90°C, 125°C, and 150°C, and the rated voltage is DC 1000V/1500V.
