Against the backdrop of the low-carbon energy transition and the release of green development momentum, the market penetration of pure electric construction machinery is gradually increasing. Data shows that from January to October 2024, the market penetration of new energyloadersand new energy mining trucks increased by 15.1% and 6.3% compared with the same period last year. However, construction machinery batteries have obvious pain points such as poor reliability, poor environmental adaptability, slow charging speed, short life, and low integration, which restrict the industry's new energy transition and also leave customers with many concerns when choosing products.

WeichaiRelease of Weichai's full series of construction machinery batteries

Facing industry challenges, Weichai's blade CTP technology perfectly matches the needs of construction machinery. On December 6, at the Off-Road Power Sub-forum of the Weichai 2025 Global Partner Conference, Weichai's new energy full series of construction machinery batteries were brilliantly released, with capacity covering 280-765kWh, which can meet the electricity needs of different market segments such as loaders,excavatorsand mining trucks. The full series of 10 batteries leads the innovation of new quality productive forces in construction machinery.

Stronger reliability, the first choice for construction machinery

Weichai has carried out customized development for the operating conditions of construction machinery, enabling the batteries to have high mechanical reliability and high environmental adaptability. In the face of harsh operating environments such as low temperatures and corrosion in construction machinery, Weichai's R&D team conducted in-depth field research and carried out forward-looking R&D based on stringent working conditions, making reliability the primary consideration. Relying on the advantages of Weichai's R&D platform, battery development has undergone more than 50 system-level experiments, more than 300,000 hours of vehicle reliability verification, and the support of "three-high" tests, creating an industry benchmark for reliability and durability.

It is reported that the vibration reliability of the newly released batteries can meet 4 times the national standard, and the system failure rate is 20% lower than the industry average; the batteries adopt efficient uniform-temperature heating technology, have better low-temperature adaptability, and support an operating temperature range of -35℃ to 65℃; they adopt CASS standard anti-corrosion coating and are suitable for a variety of harsh environments. In addition, the batteries adopt "blade CTP" technology and have natural advantages such as high-strength side beams and high integration, laying a solid foundation for new energy construction machinery to operate continuously in harsh environments.

Faster charging, higher attendance, more profitable

For pure electric construction machinery, fast-charging performance is a key factor related to operating attendance. Based on the characteristic that construction machinery usually has large battery capacity, blade batteries are naturally suitable for fast charging. At the cell level, a centrally symmetric structure is adopted; at the PACK level, efficient uniform temperature in the height and horizontal directions is achieved, and an integrated reinforced panel is adopted, increasing the current-carrying capacity by 60%, shaping the product's excellent fast-charging performance with technical advantages.

The construction machinery battery products released by Weichai this time have 400A fast-charging capability, fully unleashing the nature of blade batteries. It takes only about 23 minutes to charge the battery from 20% to 80%, effectively shortening charging time, greatly improving the equipment's operating turnover efficiency, and helping customers increase operating income by 5%. In addition, the product supports low-temperature charging at -20℃, with low-temperature charge-discharge efficiency improved by 5%, effectively improving the equipment's operating efficiency under low-temperature conditions, ensuring attendance, and enabling customers to make more money.

Ultra-long life, worry-free use throughout the full life cycle

In the use of construction machinery, equipment is a key tool for creating economic benefits, and the service life of its battery is also what customers worry about most. With multiple core technology breakthroughs, Weichai has made its construction machinery battery products stand out in the industry with both long life and fast-charging functions, allowing customers to use them worry-free throughout the vehicle's full life cycle.

Supported by a series of long-life technologies, the product adopts optimization measures such as self-repairing electrolyte, efficient uniform temperature, active thermal insulation, and super anti-corrosion. The battery system cycle life is optional at 2,800/4,500 cycles, with life increased by 60%, and it supports a vehicle life of more than 20,000 hours, perfectly solving customers' concerns about battery life throughout the vehicle's full life cycle. In addition, the battery has laid the foundation for long life from the cell level. The improvement in product life makes the product's overall cost-effectiveness more advantageous, allowing users to obtain greater returns during the product's full life cycle.
