Against the backdrop of low-carbon energy transformation and the release of green development momentum, the penetration rate of the pure electric engineering machinery market is gradually increasing. Data shows that from January to October 2024, the market penetration rate of new energy loaders and new energy mining trucks increased by 15.1% and 6.3% respectively compared to the same period last year. However, construction machinery batteries have obvious pain points such as poor reliability, poor environmental adaptability, slow charging rate, short lifespan, and low integration level, which restrict the industry's new energy transformation and also make customers have many concerns when choosing products.
Weichai releases full range of construction machinery batteries
Faced with industry challenges, Weichai's blade CTP technology perfectly matches the needs of construction machinery. On December 6th, at the Weichai 2025 Global Partner Conference Non Road Power Branch, Weichai New Energy's full range of construction machinery batteries were unveiled, covering a power range of 280-765kWh, which can meet the electricity needs of different segmented markets such as loaders, excavators, and mining trucks. The 10 batteries in the full range lead the innovation of new quality and productivity in construction machinery.
Stronger reliability, preferred for construction machinery
Weichai customizes the development of engineering machinery operating conditions to provide batteries with high mechanical reliability and environmental adaptability. Faced with harsh working environments such as low temperature and corrosion in construction machinery, Weichai's R&D team conducted in-depth field research and conducted forward research based on harsh working conditions, with reliability as the primary consideration factor. Relying on the advantages of Weichai's R&D platform, the battery development has undergone more than 50 system level experiments, over 300000 hours of vehicle reliability verification, and the support of "three highs" tests, creating an industry benchmark for reliability and durability.
It is reported that the newly released battery vibration reliability can meet four times the national standard, and the system failure rate is 20% lower than the industry average level; The battery adopts efficient temperature equalization heating technology, with better low-temperature adaptability and a working temperature range of -35 ℃ to 65 ℃; Adopting CASS standard anti-corrosion coating, suitable for various harsh environments. In addition, the battery adopts the "blade CTP" technology, which has natural advantages such as high-strength edge beams and high integration, laying a solid foundation for the continuous operation of new energy engineering machinery in harsh environments.
Charging faster, higher attendance, and more profitable
For pure electric construction machinery, fast charging performance is a key factor related to work attendance. Based on the characteristic of high power consumption in construction machinery, blade batteries are naturally compatible with fast charging. At the cell level, a central symmetrical structure is adopted, and at the PACK level, efficient temperature equalization is achieved in both height and horizontal directions. An integrated reinforced panel is used to increase overcurrent capacity by 60%, shaping the product's excellent fast charging performance with technological advantages.
Weichai's engineering machinery battery products released this time have a 400A fast charging capability, completely stimulating the nature of blade batteries. The battery can be charged from 20% to 80% in only about 23 minutes, effectively shortening the charging time and greatly improving the operational turnover efficiency of the equipment, helping customers increase their operating income by 5%. In addition, the product supports low-temperature charging at -20 ℃, which increases the efficiency of low-temperature charging and discharging by 5%, effectively improving the operational efficiency of the equipment under low-temperature conditions, ensuring attendance, and making customers more profitable.
Long lifespan, worry free use throughout the entire lifecycle
In the use of construction machinery, equipment is a key tool for creating economic benefits, and the service life of its batteries is also a major concern for customers. Weichai has made breakthroughs in multiple core technologies, making its engineering machinery battery products a leader in the industry with both long lifespan and fast charging capabilities, allowing customers to use them worry free throughout the entire lifecycle of the vehicle.
With the support of a series of long-life technologies, this product adopts optimization measures such as self-healing electrolyte, efficient temperature equalization, active insulation, and super strong anti-corrosion. The battery system cycle life is optional at 2800/4500 times, with a 60% increase in life. It supports a vehicle life of more than 20000 hours, perfectly solving customers' concerns about battery life throughout the entire life cycle of the vehicle. In addition, the battery lays the foundation for a long lifespan from the cell level. The improvement and enhancement of product lifespan make the overall cost-effectiveness of the product more advantageous, allowing users to gain greater benefits throughout the entire product lifecycle.
Weichai, as a well deserved leader in the power industry, has always established a benchmark position in the traditional power field with its profound technological accumulation, outstanding innovation capabilities, and extensive market influence. Nowadays, Weichai is actively focusing on the field of new energy, which will further consolidate its leading position and lead the entire new energy engineering machinery industry towards green, efficient, and sustainable development, contributing more Weichai's strength to the global energy transformation and green development.
