With the advancement of lithium battery technology and the continuous reduction of cost, garden tools are expected to accelerate lithium-ion.
In recent years, "Urban Green Space System Planning", "Landscaping Project Specifications" and other guiding documents have been issued and implemented, all emphasizing that the scientific implementation of landscaping projects requires technology and environmental protection. In the bidding of greening projects, it is found that the use of energy-saving machinery and equipment, environmental protection agents and logistics equipment has a significant proportion in the "technical score. Low carbon environmental protection, light has become the development direction of garden machinery products.
Application of garden tools
As the maintenance equipment of human greening landscape, garden tools mainly take the maintenance of lawns, hedges, protection of flowers and plants, trees as the object of operation, is to replace most of the manual labor as the representative of mechanized tools.
With the increase in disposable income of Chinese households, the increase in the number of houses and the growth of demand for improved living conditions, the Chinese market still maintains its market share in the region. Relevant agencies predict that China, India and Hong Kong will have a higher compound growth rate, and the compound annual growth rate of China's home and gardening market is expected to reach 13%.
From the perspective of market region, China is the main production base of global garden tools. Since garden tools are currently exported mainly, and the export method is mainly shipping, the production area is mainly concentrated in the coastal area, mainly distributed in Zhejiang, Jiangsu, Shandong and other provinces in East China.
In the past, most of the garden tools used traditional gasoline engines, which have the advantages of high power and good cutting effect. However, with the introduction of relevant environmental protection policies, the emission problems of fuel engines will add many restrictions to their development. If the garden tool is powered by an AC motor, although the cost is low, it needs to be connected to a power supply and has poor portability; but if it is powered by a DC motor or a rechargeable battery, it has the advantages of convenient use, low noise, energy saving and environmental protection.
Among them, the lithium-ion DC lawn mower uses a lithium-ion battery as a power source, and generally uses a brushless DC motor. With the accumulation of technology in the lithium battery industry, lithium battery mowers are currently developing in the direction of high power, long battery life, and intelligence, which are more in line with market demand.
Relevant data show that the global market size of power tools increased from US $22.8 billion in 2016 to US $29.1 billion in 2020, with an average annual compound growth rate of 6% and a cordless rate of nearly 50% in 2020. And the new market-outdoor power equipment (mostly garden tools) cordless into lithium demand to bring incremental.
Although the current power source of electric garden tools is still gasoline engines, the cordless rate is less than 20%. However, from the lithium-electric penetration rate increase, mowing robots, riding-hand-push lawn mowers and other products to improve, electric garden tools lithium electric is expected to improve faster.
Compared with traditional nickel-metal hydride/nickel-cadmium batteries, lithium batteries have outstanding advantages such as high withstand voltage, high energy density, strong discharge rate, long cycle life, and environmental protection, and are more favored by the market. With the development and upgrading of lithium-electric technology, positive materials by higher energy high nickel ternary gradually replaced, safety performance and multiplier performance of stronger silicon-based negative technology reserves established, lithium battery performance improvement at the same time, accounting for more than half of the cost of lithium batteries positive and negative material costs will also be reduced accordingly.
If the production cost of lithium batteries is gradually reduced, the penetration rate of cordless power tools will be further improved. Compared with Japanese and Korean enterprises, the domestic leading enterprise Jiangsu Tianpeng's quotation is more than 20% lower. Although Japanese and Korean enterprises cylindrical lithium batteries are better in consistency than domestic batteries, the gap in other indicators is not large. The price advantage of domestic lithium batteries may give domestic power tool enterprises some resource advantages.
From the perspective of user experience, the preference of end users for lithium-ion products will continue to grow. On the one hand, benefiting from the rapid change and popularization of high energy density batteries, the transformation advantages of lithium battery are obvious cost-effectiveness, safety and environmental protection, and longer service life. On the other hand, lithium-electric power tools can provide strong ease of use and maintain long-term operation in different working environments; in addition, lithium-electric OPE produces less vibration and noise, and the convenience of operation and user experience are improved. Compared with traditional gasoline engine products, it is more environmentally friendly.
At present, lawn mowers and other garden tool products are more in pursuit of wireless, small size, light weight, longer battery life, low noise, and more comfortable customer experience. Relevant solutions and device selection that meet the requirements will also be more favored by the market.
In the next 10 years, garden machinery may become the backbone of the market. Electric garden tools enterprises need to increase product development and brand building efforts to continuously improve and improve the performance and quality of garden machinery products to meet the needs of the international and domestic markets, especially to improve the safety performance of garden machinery products, reduce noise and emissions. This is the key to enhance the competitiveness of China's garden machinery industry, but also the direction of China's garden machinery manufacturing enterprises. The use of gallium nitride (GaN) technology to design compact power tool chargers with high power factor, the development trend of BMS for power tools, the technical requirements and innovations of low-voltage MOSFETs in the field of intelligent motor drive and fast charging, and the achievement of green energy in the future by gallium nitride will be brilliant.
