Concrete Mixer’s Mixing Drum Electrification Project
Client: A concrete company Demand: An EV solution for their 22 concrete mixer trucks to save fuel costs Introduction: In 2022, a concrete company approached us and wanted an EV solution for their concrete mixer trucks to reduce the fuel costs. Challenges Faced by the Concrete Company: In the concrete mixer industry, as long as the mixing tank is turning, the engine cannot be turned off. This has been a persistant challenge, leading to high fuel consumption. Between 36% and 70% of the operating conditions for concrete mixers involve idling. Although they operate for 12 to 14 hours a day, only half of that time is spent in actual motion. Prolonged idling not only significantly increases fuel consumption but also necessitates frequent engine maintenance, reducing the lifespan of the vehicles. The Axial Flux Motor Solution for Concrete Mixer: Starting in 2022, they implemented our EV system using axial flux motors. The system replaced the traditional hydraulic transmission of concrete mixers with an electrically powered attachement, achieving a separation of engine power and mixing drum power. During loading, unloading, or normail driving, the system’s onboard power battery provides the rotating power for the mixing drum autonomously, eliminating the reliance on engine power. Consequently, during vehicle idling, engine shutdown no longer affects the drum’s rotation, allowing the air conditioning system to function normally and resulting in a significant reduction in fuel consumption. Morever, the system incorporates an energy-efficient loop mechanism that automatically collects surplus power from the engine during vehicle operation to recharge the battery. As a result, the system minimally draws on the engine’s power, further enhancing fuel efficiency. Result: After almost a year of practical application, the results speak volumes: some trucks have achieved monthly fuel cost savings of up to $1000. Despite the inital investment required for the system, the company anticipates a swift return on investment, with costs recovered within a few months.
