Coincidentally，In the exhibition hall of Zoomlion，Mixer Truck、Crawler Crane、Straight arm aerial work platform and many other pure electric、New energy green products such as plug-in are unveiled.，Equipment accounts for about 30 percent。
What are the advantages of electrification?？
Zeng Guangan, Chairman of Liugong, analyzed.，At present，Under the background of carbon reaching peak and carbon neutralization，New energy technology and equipment will become one of the future development trends.。Compared with traditional fuel equipment，Electric products can achieve zero emission、Low noise，20% more productive%，The failure rate is reduced by 30%。
Not only that，Electric construction machinery also has better economy.，The comprehensive cost during the service life can be reduced by 50% compared with that of the fuel machinery%To 70%。
Look at the electric Excavator，The person in charge of Guangxi Fangchenggang Jimei Chemical Co., Ltd.，I used to use 320 fuel Excavators.，Fuel consumption 16 litres per hour，The daily fuel cost is 2600 yuan.。After the introduction of electric excavator，Average power consumption per hour 66.7 kWh，The daily electricity bill is less than 1000 yuan.。
“That's how it works，An item of light electricity charges，One equipment can save nearly 500000 yuan a year.，In addition, the electric excavator avoids maintenance costs such as oil replacement.，Lower cost of use。”The person in charge said。
Look at the electric mine car，He Huaqiang, director of Sany International Mine Car Technology Research Institute, introduced.，The mine car has a heavy load going up.、Three working conditions of flat road and heavy load down。Potential energy can be converted into electric energy when the mine car goes down under heavy load.，Calculated by attendance of 20 hours a day，Only need to charge once a day，It can save 300000 to 500000 yuan annually.，Save 80% compared with traditional oil Vehicles%The cost of。And that part of the electric mine car are less.，Attendance is better，The failure rate is lower，Lower maintenance costs。
“Although the initial purchase cost of electric construction machinery is relatively high at present.，But the whole life cycle is calculated.，Electric products are more economical.。”Su Zimeng said，And as that technology further improve,，The cost of electric products will be further reduced in the future.。
Overcome new difficulties
Domestic new energy supporting industry has provided a strong boost.
Electric Construction Machinery，Batteries are critical。Statistics show that，On the cost side，Batteries account for 40% of the total cost of electric construction machinery%To 50%。
“Compared to passenger cars，There are many kinds of construction machinery.，The working environment is worse.，Greater operating power requirement，It puts forward higher requirements for batteries.。”Su Zimeng introduced，For this reason，The head construction machinery enterprises all over the world have in-depth layout of electric equipment.，Technology self-research is also related to“Three electricity”Deep cooperation between enterprises。
For example，As early as 2020，Sany Group signed a strategic cooperation agreement with Ningde Times.，Close cooperation in new energy construction machinery and other fields。At present，Sany Electric Mixer with Ningde Times Battery、Electric muck truck、Electric Dump Trucks and other products have been in Henan、Yunnan、Batch application in Xinjiang and other regions。
XCMG Joins Hands with BYD to Set up Battery Joint Venture Factory。January 4 this year，Foundation of BYD New Energy Power Battery Production Base in Xuzhou，The total investment is 10 billion yuan.，Construction of blade battery production line，Part of the production line is planned to be put into operation in December 2023.。
“At present，The scale of China's power battery industry has been in the leading position in the world，It pioneered a number of patented technologies in the field of special power batteries for construction machinery.，Provide strong support for the research and development of electric products of construction machinery。”Jiang Yuwei, technical director of Ningde Times Heavy Truck and Construction Machinery, said.。
