CHINA REPORT
Electrification has become one of the important directions of green development within China’s construction machinery segment. Domestic construction machinery leaders have increased the development of equipment electrification and have launched a variety of electrification products.
Some professional organizations predict that by 2025 the penetration rate of main products may reach 25%. The electrification of construction machinery initially replaces conventional diesel engine drive with electric drive and then the hydraulic device is replaced by an electric device. Concrete mixers, truck cranes, muck trucks, excavators and wheel-loaders are the most easily electrically driven products, especially for small construction machinery.

PSR Analysis: At present, the subcategories applicable to closed and fixed working environments such as ports, municipal vehicles and mines have taken the lead in moving towards electrification. Most Off- Road products face several challenges. One is that the capacitance is not enough and a lithium iron phosphate battery has a service life of less than five years. There is a big gap compared with traditional diesel engines.
On the other hand, the use cost has been reduced, but the manufacturing cost or one-time purchase cost is still very high.
At the same time, construction conditions of electric construction machinery charging pile limit the scope of electric machinery. Mines and other remote construction sites face these challenges. The current use environment is not particularly positive, because the charging conditions at the work site are generally not very good.
The implementation of China IV emission standards of the Off-Road segment will bring benefits to the electrification of the construction machinery from the policy level. How to reduce product cost is still a difficult problem for enterprises, and battery cost may be a problem for many enterprises.
Some other issues such as poor battery safety, short mileage and insufficient supporting charging equipment will also be the key to technical breakthrough in the future. PSR
