Chilwee is a large-scale enterprise specializing in the R&D and manufacturing of power and energy storage batteries. However, it is not the same brand as Superb, which is familiar with mosquito coils and insecticides, and there is no relationship between the two. Chaowei in the field of batteries, especially in the field of electric vehicle batteries, the reputation is not weaker than that of the brothers of the same name, the market share of electric vehicle batteries is the first in the industry, with an annual output of 180 million electric vehicle batteries.
 
In terms of automotive batteries, Chaowei cooperated with Moll of Germany and established Henan Chaowei Zhengxiao Power Supply Co., Ltd., which followed the battery technology of Moll of Germany. Moll is a German battery manufacturer with a history of nearly 80 years, and has obtained many battery-related patents over the past 50 years. As an important supplier of many German car companies, Moll is the designated partner of Porsche, Lamborghini, Audi, Volkswagen and other famous car brands, and has a 50-year cooperative relationship with Volkswagen.
 
The start-stop battery that supports the start-stop system is divided into AGM battery and EFB battery. Among them, the start-stop EFB battery was first created in Moll, Germany. The engine start-stop system is the most rapidly developing energy-saving technology in recent years, especially suitable for stop-and-go urban road conditions, and the new car is mostly started with the start-stop system. Moll is a world leader in EFB and AGM technology, and the cooperation with Chaowei began in 2014, and the market and publicity have not yet been rolled out, and it is a potential stock among automotive battery brands.
 
Chaowei series products include maintenance-free series and EFB start-stop series. The maintenance-free battery adopts the Italian Sovema grid manufacturing technology, the German Eirich vacuum and paste technology, and the South Korean Moojin assembly line, which can be called the culmination of many foreign first-class technologies, but it is also the reason why the technology is introduced more than the original, and the electrical performance, especially the capacity control, is still a long way from the first-line brand.
 
For northern regions with extremely low winter temperatures, especially in weather with temperatures of -20°C or lower, it may be difficult to start the car and be trapped in the cold outdoors. In fact, the products of some foreign battery brands will be marked with the use climate, the southern region suitable for hot climate is marked as S, and the northern region suitable for cold climate is marked as N, S type is more resistant to high temperature, and N type is more focused on improving the CCA starting coefficient. However, although China has a large north-south span, it has not introduced this method, so it needs to be judged by the CCA value by itself.
 
The so-called CCA is an important parameter that needs to be referred to for cold weather starting, and the Chinese name is cold start current, and the unit is amperes (A). A higher CCA value means better starting capability and better battery performance. It is not recommended to choose a battery that is lower than the performance index of the original battery, which will lead to poor start-up and unstable voltage, which in turn will damage the on-board electrical appliances and lead to battery failure. Of course, a battery with a high CCA value can only ensure that it is easier to start in extreme situations, but the temperature is too low, such as -30°C, and it is extremely difficult to start a non-special lead-acid battery.
 
Among the batteries of the same model, taking the L2-200 battery suitable for Jetta and other cars as an example, the maximum CCA of the VARTA Silver Label is 600A, followed by the VARTA Blue Label and Bosch 580A, and the next echelon is Chaowei and Camel are 550A and 570A respectively, and Yuasa, Fengfan and GS are not very ideal, all below 500A. The price of Chaowei maintenance-free battery is low, and the L2-400 battery is only 460 yuan, which is the lowest price in the industry.
 
Chaowei has its unique offline channel advantages, and there are Chaowei battery repair and assembly shops in various cities and even remote towns, which is one of the fastest brands that can be installed and replaced at home.
