On April 24, the 2024 Electric Bicycle Battery High-Quality Development Conference was held in Beijing. With the theme of "Safety and Sharing", the conference was hosted by China Electronics Quality Management Association, undertaken by China Electronics Standardization Institute and Beijing Bicycle and Electric Vehicle Industry Association.
As the key co-organizer of this conference, Xingheng has always been a representative of the lithium-ion battery industry for electric bicycles, and was invited to attend the conference and give a keynote speech, sharing the "Xingheng experience" and "Xingheng solution" with the industry for the development of industrial safety and compliance, and passed the mandatory national standard (draft for approval) evaluation of lithium-ion batteries for electric bicycles, becoming the first batch of enterprises in the industry to pass the mandatory national standard evaluation of lithium-ion batteries for electric bicycles.
The "Xingheng Program" has been recognized by the authority and has taken the lead in entering the era of lithium battery national standard for electric bicycles
At the conference, the list of enterprises that passed the mandatory national standard evaluation was released, and Xingheng produced 2 products on the list with profound technical accumulation and industry responsibility, which means that Xingheng's lithium battery products have passed the technical strength, performance indicators and safety guarantee of the national strong standard certification, and will be the first to enter the era of electric bicycle lithium battery national standard.
The product submitted for inspection is Xingheng DZ48N-20EM lithium battery
The product submitted for inspection is Xingheng DZ48N-24EM lithium battery
The national strong standard stipulates more than 30 safety technical indicators such as overcharge, overdischarge, battery pack temperature protection and overcharge protection of single batteries. In addition, personal safety-related items have been introduced into the national strong standard, and requirements have been made for battery thermal diffusion control capabilities, mutual recognition and collaborative charging, etc., and safety requirements have been strengthened.
This pass of the national strong standard evaluation is a high recognition of the industry's leading technical strength and reliable product quality by the industry's authoritative institutions, which represents that Xingheng's technology, products and solutions meet the strict indicators of the national strong standard, and can take the lead in launching the national strong standard lithium battery products in the industry, quickly meet the needs of the market and users to use the national strong standard lithium battery products to ride with peace of mind, and further promote the healthy, compliant and orderly development of the industry.
Create a high-standard, high-demand safety lithium battery, and protect the travel of Chinese people with a full life cycle safety system
The reason why Xingheng can take the lead in passing the national strong standard evaluation is due to Xingheng's insistence on high standards of precision manufacturing for materials and products. In the keynote report session, Xingheng, as the first company to share on stage, shared the high safety of Xingheng lithium battery products in multiple dimensions through the theme report of "Safe Application of Manganese-based Lithium Batteries on Electric Bicycles" by Sun Daqiang, chief expert of the Battery Cell Production and Research Center, and brought the "Xingheng Solution" for the high-quality development of the lithium battery industry for electric bicycles.
Sun Daqiang said that Xingheng manganese-based materials have extremely high safety, first of all, from the self-developed precursor material - MFO manganese iron oxide. In view of the problems of long-term cycle voltage attenuation, poor low-temperature performance and poor fast charging performance of lithium manganese iron phosphate materials in the industry, Xingheng has created the world's leading lithium battery genetic material - MFO manganese iron oxide precursor synthesis technology, which obtains manganese iron oxide from manganese source and iron source through a series of processes, and successfully synthesizes lithium manganese iron phosphate material with stable structure and better rate performance, with stable structure and dense crystal, which can effectively inhibit manganese dissolution and improve the low-temperature performance and fast charging performance of the material.
With the support of this technology, Xingheng monocrystalline lithium manganese oxide + lithium manganese iron phosphate "golden dual-core" composite material technology can achieve high performance and high safety, and the "golden dual-core" material system of Xingheng lithium battery can safely pass the 1.5 times overcharge test and the acupuncture test of authoritative institutions, without smoke, fire and explosion.
Mr. Sun also introduced the "six safety systems" of Xingheng to ensure product safety in an all-round way, and focused on PACK safety and BMS safety. In terms of PACK safety, Xingheng carries out safety structure design based on market applications and user needs, V0 flame retardant shell material, and multiple safety protection designs such as "self-extinguishing from fire" standard, which greatly enhances the structural safety of the battery pack.
In terms of BMS safety, the BMS Apocalypse Management System independently developed by Xingheng can realize eight safety protections such as battery safety detection and protection, BMS failure self-test, BADCELL protection, ESD electrostatic protection and EMC anti-electromagnetic interference that meet the EU 15149 standard.
The S7, S20 and other series of products exhibited by Xingheng at the scene are the best interpretation of "safe lithium battery and Xingheng manufacturing". S20 series lithium battery is the industry's first batch of lithium battery series that meets the GB 42295 specification of "Electrical Safety Requirements for Electric Bicycles", which is safe, reliable, compliant and compliant, and has not only been highly recognized by Li Qiang, deputy director of the Consumer Goods Industry Department of the Ministry of Industry and Information Technology, and other leaders, professional institutions and authoritative media, but also has become the focus of attention of many vehicle brands and shared operations.
Playing an exemplary role, Xingheng leads the wave of compliance development in the industry
Compliance development is the only way for enterprises to develop with high quality, and it is also an important foundation for promoting the healthy and sustainable development of the industry. In recent years, in order to promote the compliance of the industry, Xingheng has taken the lead in demonstrating in the industry and carrying the "pioneer flag" of the development of the lithium battery industry. At this conference, whether it is the honor of the first batch of enterprises that have passed the authoritative certification, or the professional technical explanation and dazzling product display, it is an important driving force for Xingheng to play an exemplary role and lead the compliance development of the industry.
Facing the future, Xingheng will take the national standard system as the baseline for product research and development, insist on starting from the bottom line of protecting user safety, continue to strengthen the product safety factor with technological innovation, create more compliant and safe lithium battery products to the market, and contribute to the acceleration of industrial compliance.
