"Four defenses, three mentions" This battery company "draws" the second curve of technological growth

Electric bicycles have long become one of the tools that people need to travel freely in the short and medium distance. In order to ensure the safe use of electric vehicles and curb the occurrence of safety accidents, the state issued the "Technical Specifications for the Safety of Electric Bicycles" (hereinafter referred to as the "Specifications") in April 2019. Many cities have set up a "transition period" for this purpose, leaving time for the elimination of electric bicycles that exceed the standard and the implementation of new standard electric bicycles.

Some institutions predict that in 2021-2024, the mainland will usher in the peak period of electric bicycle replacement, and it is expected that 50-60 million electric bicycles need to be replaced, and the demand for electric bicycle batteries is strong.

It is worth noting that the "Specification" adds requirements for safety technical indicators such as "fire performance, flame retardant performance, charger protection" for batteries to improve the safety and security of cyclists.

In addition to safety and security, electric bicycle manufacturers and cyclists are also paying more and more attention to the battery range, low temperature performance, cycle times and other aspects of performance. At present, electric bicycle batteries have technical routes such as lithium batteries and lead-acid batteries. In order to meet the new market demand, battery companies have increased investment in technology research and development.

As an early layout of the electric bicycle power battery industry, Chaowei Group has not only participated in and promoted the development of electric bicycles, but also won the attention of CCTV. Recently, CCTV2's "Punctual Finance" column focused on Chaowei lithium batteries and went deep into the lithium battery production workshop of Chaowei Chuangyuan Company to visit the field. According to the relevant person in charge of Chaowei, the company's sales department lithium battery orders have been growing, and the production line is basically running at full capacity. With the development of the new energy industry, the market space for lithium batteries will become larger and larger.

It is understood that the reason why Chaowei products can gain market favor for a long time is mainly due to the continuous progress of Chaowei batteries in cutting-edge technological innovation, improving safety performance, expanding high-quality partners and super after-sales service.

Chaowei battery in the technical investment can be described as a large amount, the current R & D investment has reached billions of yuan, with 19 R & D institutions in the world, thousands of technical experts, which also reflects its scientific and technological hard power.

In the field of power lithium batteries, Chaowei batteries use high safety lithium manganate and long-life lithium iron phosphate two kinds of lithium ion battery cathode materials, and there are many technological breakthroughs in the safety performance of products.

In fact, for power lithium batteries in practical applications, lithium analysis, small particles and overcharges inside the battery and other factors will induce the vicious event of battery fire and explosion, and the safety of lithium batteries can generally be evaluated by testing such as high current short circuit, squeeze needle punch, and overcharge.

Taking Chaowei 20Ah soft pack lithium manganate battery and 20Ah soft pack lithium iron phosphate battery as an example, after needle prick or overcharge test, the battery does not fire and does not explode.

In addition to the safety test required by the national standard, Chaowei Group also implemented an extreme safety test, and the above two batteries were crushed and tested at a height of 5m, and the battery did not catch fire and did not explode.

In addition, in daily life, cyclists may also encounter extreme weather such as storms, which also tests the waterproof performance of the battery. Chaowei lithium battery products can reach the IP7 level of waterproof level, the battery is soaked in water, the battery can still continue to power the electric bicycle, and does not hurt the fish in the water tank, to achieve the "water tank in the battery and fish" harmonious coexistence state.

These "four anti-internal short circuit", "anti-overcharge", "anti-pressure and anti-fall", "waterproof" "four anti- " safety requirements, all originate from some unexpected situations in the daily use of electric bicycles, and are also the battery performance indicators that consumers are most concerned about. With the needs of consumers as the core, Chaowei Group provides safer lithium batteries for the market from the perspective of technology research and development and lean production.

In addition to the development and production of lithium batteries, in order to meet the needs of customers at different levels, Chaowei has continuously integrated new technologies into the original lead-acid battery advantage technology route. Its latest super-energy graphene battery has the support of graphene high-end technology, which further improves the energy density of the battery.

In terms of mileage, the battery has experienced nearly a thousand "Super Energy Mileage Challenges", which fully proves the excellence of its battery mileage.

In terms of low temperature performance, in January 2022, Chaowei ultra-energy graphene batteries conquered China's snow towns, and still achieved a long endurance of 98.3km in the extreme environment of minus 30 °C. It provides a better experience for the use of cars in the low temperature environment in the northern region in winter.

In terms of the number of cycles, this battery adopts an efficient reinforced alloy, which improves the conductivity, corrosion resistance and creep resistance of the grid interface, improves the over-discharge performance of the battery, and makes the battery more durable and longer-lasting. Through the "three mentions", the traditional technology is revitalized again.

Whether the product is good or not, the market sales will give the answer. Nowadays, the "figure" of Chaowei battery is all over the streets and alleys, whether it is the head of the vehicle, or consumers, the Chaowei battery has a reputation. Taking the Chaowei black gold battery as an example, it is reported that more than 50 million are sold a year, and there are 1,000 Mount Everest heights stacked on top. At present, the downstream strategic partners of Chaowei Battery include Yadi, Luyuan, Tailing, Emma, Lima, Knife, Golden Arrow and other OEMs, as well as some foreign customers, with diversified and multi-level customer structures.

On the basis of meeting customer product needs, Chaowei Battery does not forget to improve after-sales service. This is especially important as the last line of defense for the end-user experience. Nowadays, Chaowei Battery 30W+ service outlets have spread all over the country and many countries (regions) in the world, as well as the official website, WeChat public account entrance, 400 customer service hotline, from offline to online, all hope to bring users a more convenient and efficient service experience.

At the beginning of this year, Chaowei Group held a technical exchange meeting with the top 30 electric vehicle head enterprises in the industry, and officially released the "Declaration on the Energy Upgrade of China's Electric Vehicle Batteries in 2022", marking that the industry has entered a new development cycle.

At present, Chaowei battery products have been exported to more than 100 countries and regions around the world, as a top 500 Chinese enterprises, China's top 500 manufacturing enterprises, China's top 500 private enterprises, Chaowei battery is walking on the second curve of technological development, its development logic is to take technology as the core, based on power, energy storage, consumer batteries and other fields to develop applications, the product into more application scenarios.

It is expected that with the advancement of the pace of electric bicycle replacement, the head battery company will open a new round of competition to seize market share. The market share will move closer to the head battery enterprises with technical advantages, rich channel resources and perfect after-sales system, and the market concentration will be further improved.
