A few days ago, the first domestically developed new energy electric bus featuring an extended-range power system made its debut and successfully completed a roadshow covering over 1,300 kilometers. This groundbreaking vehicle, branded as "Hualong," was co-developed by Henan Jinyi New Energy Group and Shenyang Hualong New Energy Automobile Co., Ltd. The roadshow not only showcased the practicality of this innovative technology but also provided real-world data that supports its potential for widespread adoption in the public transportation sector.
The extended-range power technology behind the Hualong bus is backed by exclusive core invention patents and has even earned the Second-Class National Invention Award. With motor and generator efficiency reaching up to 98.2%, this system offers a major breakthrough. Unlike traditional
Battery-electric buses, the Hualong doesn’t require charging stations during operation, effectively solving one of the most significant challenges in the electric vehicle industry—range anxiety.
According to Chen Junyan, Chairman of Jinyi New Energy Group, the extended-range bus incorporates a range extender that optimizes both electricity and fuel usage, delivering impressive environmental benefits. “To achieve this, we integrated an automatic battery-charging system into the original pure electric design, known as the Auxiliary Power Unit (APU). This APU includes a small-displacement internal combustion engine, a high-efficiency generator with over 98% efficiency, and a control system that converts traditional fuels like gasoline or natural gas into electricity,†he explained.
The range extender brings four key advantages: it significantly reduces the need for frequent charging, improving vehicle utilization; enhances battery stability and lifespan, lowering fire and explosion risks; cuts fuel consumption by more than 50% compared to conventional city vehicles; and allows for short-distance travel in fully electric mode, up to 100 kilometers. Once mass-produced, this new energy bus is expected to play a crucial role in urban public transport systems, offering a sustainable and efficient alternative to traditional fuel-powered buses.
182mm Mono Solar Panel
From the upgrade of the existing 158.75 and 166 production lines, the process span of 182 solar panels is smaller, and the existing equipment and processes are more mature. Therefore, the difficulty and cost of new or upgraded production lines are lower, and the product yield rate is currently normal. PV industry experts suggest that the advantage of 182mm is that the industrial ecology is more mature, and it is the optimal size silicon wafer that meets the current development level of upstream and downstream, and is the first choice at this stage.
Sunket 182mm Solar Panel use 182mm 10BB/11BB Solar Cell, increases the wafer size, optimizes the layout profoundly and decreases the invalid power generation area.
1.Half Cell Technology
The half-cut cell design can decrease the power loss by the shadow effectively. The optimized circuit design not only realizes the maximum power output but also assures the reliability of solar panels.
2.MBB Technology
Sunket 182mm Solar Panel adopts multi-busbar technology. More busbars of the cell decrease the current transverse propagation path by 50%, effectively reduce the internal loss, and improve power of solar panels.
