Cement Mixer Truck (24V/400V Platform) Development (P2 Hybrid + ePTO Hybrid System)

This technical white paper establishes a rigorous engineering framework for retrofitting cement mixers with 400V hybrid power systems, focusing on ensuring component longevity in high-vibration and high-heat construction environments. The document is structured into six strategic domains, prioritizing a zoning strategy that mandates placing sensitive electronics in "cold zones" away from engine heat and rotating machinery. Key technical themes include the adoption of a back-of-cab battery layout to balance safety and axle loads, and the implementation of active thermal management via refrigerant-based chillers to prevent power loss during stationary mixing. Ultimately, the text defines strict mechanical and electrical "red lines"—such as mandatory IP69K waterproofing and kinematic mounting to decouple batteries from chassis twist—to ensure these advanced systems survive a ten-year operational lifespan in the world's harshest working conditions.
