On June 4th, the day before World Environment Day, BYD, as a global green travel advocate, held a tour of the third BYD plant after Hangzhou and Shenzhen and went to BYD pure electric in the high-tech zone of Xi’an, Shaanxi. The bus factory, which is the latest production base for BYD commercial vehicles, is also the largest of the four factories in the northern region.
Annual production capacity of 5,000 green bases
Entering BYD's factory workshop, it was clean, tidy, and organized. It was the reporter's first impression. Workers were steadily taking control of the time to complete the delivery of the K9 pure electric bus order for public transport in Anyang, Henan Province. Then, there were orders for Kashgar in Xinjiang to be put into production. .
According to Zhang Zhiyuan, the director of the BYD Xi'an plant, BYD attaches great importance to factory management, and has strict requirements on the cleanliness, temperature and humidity of the whole plant. This is just a microcosm of BYD's “craftsmanship spirit”.
It is understood that the Xi'an BYD new energy automobile project has a total construction area of more than 90,000 square meters. Plans include self-manufactured parts workshops, parts workshops, welding workshops, painting workshops, assembly workshops, final assembly workshops and testing lines. Welding, painting, assembly and interior assembly of parts and components, passenger car inspection and other work.
In the welding shop, the reporter saw two assembly lines and a skeleton assembly and frame lifting platform to complete the assembly and welding of vehicles. Most notably, the workshop cited the key component of the double-slip machine and BYD. Star product K8S pure electric double-decker bus is completed with this equipment.
Afterwards, the reporter went to the painting workshop. The workshop was composed of two workshops. It has 9 drying rooms, 9 grinding rooms, and 2 foaming rooms. It has a constant-humidity vehicle for water-based paint spraying. Rotary spray booth, vehicle painting and anti-corrosion treatment are completed in the workshop.
After the assembly line and the final assembly line of the assembly line, the vehicle has basically been formed. At this time, the most crucial step is to complete the vehicle inspection. According to reports, the BYD Xi'an plant uses an automatic vehicle inspection system, including vehicle speed, axle load, and Moving, lighting, sound level, slippery, rain and other items, daily detection capacity of up to 20 units. This is BYD pure electric bus to achieve 'zero accident' operation based.
According to Zhang Zhiyuan, Xi'an plant can complete the production of 14 pure electric buses per day when two production lines are produced at the same time. The factory has a maximum annual production capacity of 5,000 vehicles, which is mainly targeted at Xi’an and Northwest China.
Three green products with the first core technology
At the scene, BYD demonstrated a pure-electric passenger car K9 that had just off the assembly line. According to Xiao Haiping, PR Director of BYD Commercial Vehicle Group, K9 is BYD's pioneering work in the field of electric buses. It is a user word of mouth and market sales. Double Good's quality products. This model adopts a one-step low-floor structure and a full-channel design. All-aluminum body is further reduced in weight, which helps improve cruising range. At the same time, it improves corrosion resistance and extends vehicle life.
It is worth mentioning that in addition to the core 'Three Powers' independently developed by BYD, this model also uses the three core technologies pioneered by BYD: wheel-side drive, bidirectional inverter charging and discharging technology and power battery thermal management system. .
Among them, the wheel drive is BYD's global initiative in 2010, with high power density, high efficiency, high reliability and diversification advantages, the most intuitive is to reduce energy consumption and increase driving range; bidirectional inverter charging and discharging technology for pure electric The passenger car has a breakthrough meaning, so that the pure electric passenger car not only stays at the power consumption level, but also has the ability of 'power supply'. It can realize the mutual energy conversion between the car and the load, the car and the power grid, and the car, and can give Rescue equipment power supply; and the introduction of power battery thermal management system has greatly increased the scope of application of the vehicle, to get rid of the limitations of temperature, by ensuring that the battery cell temperature is stable within the set range, ensure that the power battery in all environments are the most Excellent performance.
In addition, BYD is actively leading the trend of integration, standardization and modular design to provide more economical and more efficient solutions for the production, maintenance and vehicle safety of new energy buses.
According to Xiao Haiping, at present, these superior technologies have been widely used in BYD's various products, becoming BYD's leading technical support.
Doing 'Green Northwest' actor
In fact, BYD chose Xi'an as its starting point for exploring the new energy market in the northwest, and it also originated from its 'historical roots' with Xi’an. As early as January 2003, BYD Auto completed its new plant in Xi’an, after 15 years of development. , At present, Xi'an BYD base has achieved the entire industry layout of passenger cars, passenger cars, electronics, rail transportation, and automobile finance.
In the promotion and application of new energy vehicles, Xi'an K9, the first 50 pure electric buses purchased by Xi'an, was put into operation in 2013. This is the second batch of pure electric passenger car orders BYD after Shenzhen. In the past two years, BYD The cooperation with Xi’an Bus has become increasingly close. In 2016 and 2017, two orders for pure electric buses were signed, which were 1,100 and 1,900 respectively. The commissioning of these two batches of vehicles will also significantly increase the electrification level of public transport in Xi'an. .
According to Guo Jujun, general manager of BYD Northwest Market, the quantity of BYD pure electric buses in the northwest region has been steadily increasing year by year. It has now become the largest brand in the northwestern region, accounting for 36% of all public transport vehicles. Only last year, BYD was In the northwestern area, the replacement of public transport reached 2,600 vehicles, accounting for 36%.
Judging from the current situation of the promotion of new energy vehicles in China, the northwest region still belongs to a relatively blue sea area and there is great room for development. We believe that with the unremitting efforts and efforts of green actors represented by BYD, 'Green Northwest' is in people's hearts. Not only does it mean magnificent scenery, but also fresh air and blue sky.
