Electric energy storage cable, how to speed up to the era of clean energy

Faced with the limitation of traditional energy and the serious damage and pollution of atmosphere and environment caused by its large-scale application, the research and development of clean new energy has become an important strategy for the scientific and technological development of all countries in the world, energy storage system has entered a period of rapid development with the strong support and promotion of governments. The cable, an important part of the energy storage system, will meet the golden period of new product development with the development of the whole machine.

Today we are going to introduce is in the energy storage system plays an important role in the power storage system with batteries connected to the cable.

The product has a broad market

The 2021’s Global Economic and Social Development Program supports the development of new energy vehicles and energy storage industries, among other priorities. Global Energy Storage is accelerating, with global investment expected to exceed $660 billion over the next three decades.

The battery connection cable is mainly used for the connection between the DC side of the battery module, between the battery cluster, between the battery cluster and the bus box and between the battery cluster and the energy storage converter in the power storage system, is an integral part of the energy storage system, has a huge market potential.

The Slocable has been undergoing validation testing for several months since November 2019, so far, the battery connection cables for the power storage system have completed all the project tests in the standard (PPP 58049A: 2019 and CQC 1143-2019) jointly formulated by T üv and CE, and have passed the T üv product audit smoothly. This means that the use and safety performance of Slocable energy storage system with battery connected cable products meet the strict requirements of international and domestic standards. Slocable follows the mainstream of the market to develop the first time the energy storage system dedicated cable, and participate in the energy storage system for battery cable standards.

Product performance advantage

（Physical drawing of cable）

Energy storage cables are used in DC systems with rated voltages up to and including DC1500V and a maximum temperature rating of 125 °C. Due to the service environment of the energy storage cable, the service life, high and low temperature resistance, chemical resistance, battery acid resistance and combustion performance of the cable are strictly required:

　　1

Excellent electrical performance;

　　2

Acid and alkali resistance, salt fog resistance, UV light resistance, with long-term outdoor use characteristics;

　　3

Low smoke, halogen-free, flame retardant performance requirements;

　　4

Good softness, the rebound angle of softness is not more than 40 ° ;

　　5

Cable Life Assessment: the temperature index at 20000h extrapolated from the Arrhenius regression curve is not less than 125 °C.

Drafting of “Battery connection cable for electric energy storage system”

In the standard-setting process, Slocable is actively involved in the drafting of the standard for connecting cables with batteries in electric energy storage systems while combining with the market leading edge to develop products. The mechanical and electrical properties, cable life assessment and aging resistance of the battery-connected cables used in the energy storage system are comprehensively evaluated, especially considering the characteristics of different service environments in the energy storage system, the test indexes, such as bundle flame retardant, battery acid resistance and softness evaluation, have been added, and the long-term outdoor cables have been tested for resistance to sunlight aging, near the seaside or high temperature and high humidity environments for resistance to salt spray, to ensure the reliability of the battery cable used in the energy storage system.

The development and utilization of clean energy on a large scale can effectively reduce the dependence of economic development on fossil fuels, restore and protect the Earth’s ecology, and enable the world to achieve sustainable development. Slocable will take on the responsibilities of industry leaders to promote higher quality and more efficient development and upgrading of clean energy.
