With the strong advocacy of green low-carbon environmental protection travel, a large number of new energy vehicles have brought greater pressure to the power grid, the power grid needs to meet greater power demand, in view of the major impact on the power grid, including the progress and growth of solar energy, wind energy and other technologies is an important factor driving the rapid development of energy storage.

Energy storage is a key technology to promote the replacement of fossil energy to renewable energy, mainly to solve the problems of unstable new energy power generation, time mismatch and energy waste. In order to ensure that new energy power generation is in a relatively stable state and reduce the waste of electricity, energy storage technology came into being. In order to cope with the changing demand for electricity, the energy storage industry needs to continue to progress and development, including energy storage equipment, energy storage harness and other supporting facilities need to be constantly improved.

Energy storage systems are designed to manage the level of electricity needed to supply customers during peak periods of demand, make the use of renewable energy smoother, and inject it into the distribution system. Energy storage system is an important device for balancing microgrid, achieving a stable balance between power generation and load, and maintaining a balance between network load and power generation.

Energy storage is conducive to peak cutting and valley filling of the power grid, alleviating peak power supply pressure, absorbing new energy, and improving the flexibility of power grid operation. Battery energy storage systems are technologies that use multiple batteries to store electricity, first charging the batteries and then releasing the power as needed. The power storage system needs stable and reliable signal and data connection, which cannot be separated from the role of energy storage harness.

Energy storage cable is an important part of the energy storage harness, using a multi-strand or single-strand conductor structure design, while adding special materials in the conductor and insulation materials to improve the transmission efficiency and electrical performance of the cable. The selection of energy storage harness specifications in practical applications needs to be selected according to different usage scenarios.
