Which solution is better for an electric wheel loader:"triple-motor" or "dual-motor plus single gearbox" ?

As electrification becomes the inevitable path for the transformation and upgrading of construction machinery, the choice of technical route determines a company's strategic positioning. The"triple-motor solution" vs. the "dual-motor plus single gearbox solution" is not only a simple contest of superiority, but rather an industry-wide choice concerning the "depth" and "breadth" of electrification "overturn"and "continuity" ,together, they propel the industry toward the era of electric drive.

Core Divergency: Disruptive Innovation vs. Inheritance Evolutionary

The fundamental difference of these two solutions stems from their different deconstructive logics upon traditional powertrain structures.

AOLITE's E606 triple-motor solution: a complete platform-level revolution.

This solution eliminates traditional components such as gearboxes and driveshafts, adopting a "dual travelling motor plus single working motor" layout. The travelling and working systems are completely decoupled, moreover,the power transmission is transformed from a mechanical rigid connection to electronic signal control which reconstructs the underlying power structure.

AOLITE's E615 dual-motor plus single gearbox: Precision Power Source Replacement

This solution replaces the engine with a high-power motor while fully retaining the mature mechanical gearbox and drive axle. The power transmission path remains consistent with that of fuel-powered vehicles, representing an electrification adaptation built upon a mature mechanical system rather than a reconstruction.

Route Strategy: Efficiency Futurists vs. Pragmatic Reliabilities

Triple-Motor: Anchoring a Future of Efficiency and Intelligence.

The advantage of the triple-motor solution is rooted in its simplified structure and upgraded electronic control system. By eliminating mechanical transmission procedure, it significantly reduces energy losses, moreover,the electronic control system dynamically allocates power in real time achieving ultimate energy efficiency,simultaneously, offers enormous potential for intelligent applications. Furthermore, the simplified structure lowers operational and maintenance costs, aligning with the industry's long-term evolutionary needs. However, it entails higher initial costs and imposes new demands on control technology and maintenance systems.

Dual-motor plus gearbox: Grounded in Current Reliability and Cost-Effectiveness

The core of this solution lies in its inheritance of traditional technologies. The mechanical components have been rigorously proven in the market, perfectly aligning with the core demand of "robustness and durability" in construction machinery. Relying on a mature supply chain, its R&D and manufacturing costs are lower, making purchase and maintenance more manageable, thereby, accelerating the market adoption of electric products. Meanwhile, the mechanical structure boasts extensive experience in withstanding impacts and overloads, offering more responsive operation. However, inherent mechanical loss limits its energy efficiency upper limit and somewhat restricts its capability for intelligentization .

Scenario Selection: Adapting to the Present or Leading the Future?

The competition between the two routes represents the parallel coexistence of "present adaptation"and "future leadership."

In the long run, the triple-motor solution represents the ultimate direction. The core of electrification is high efficiency and energy saving, coupled with intelligent technology. With technological costs decrease, the triple-motor solution will lead the industry into a new era of "pure electric plus intelligent"which will be the primary focus of AOLITE's R&D efforts.

As for the current market, the "dual-motor plus gearbox" solution is more widely adopted. During the initial phase of electrification penetration, users prioritize reliability and cost.Thus,this solution enables traditional users to embrace electric equipment with minimal conversion costs, serving as a key force for rapid market expansion.

Dual-track in parallel, jointly embracing the electric future

The triple-motor solution is like a pure electric vehicle designed from scratch, pursuing the optimal solution and leading the transformation,yet, the dual-motor plus gearbox solution resembles a mature "fuel-to-electric" model, based on the existing system and empowering popularization.

For users with sophisticated operational needs, the triple-motor solution offers more significant long-term benefits; for ordinary users who prioritize reliability and cost, the latter is more pragmatic. In the short term, the two solutions will coexist, precisely matching the different users needs,however, in the long run, the deeply integrated, drive-by-wire triple-motor solution will ultimately become an irreversible trend, propelling the industry to leap from "electric substitution" to "intelligent upgrading."
