Not all liquid cooling systems are suitable for "oil-to-electric" conversions!
Many mistakenly believe that general-purpose liquid cooling systems are universally applicable and simply install standard modules when converting heavy-duty internal combustion vehicles to electric power. However, heavy-duty operations present unique challenges; blindly adopting off-the-shelf solutions easily leads to malfunctions and safety hazards. Vehicles such as mining trucks, heavy-duty trucks, and construction machinery operate under full load for extended periods, endure frequent start-stop cycles and intense vibrations, and face dusty environments with extreme temperature fluctuations-conditions vastly different from those experienced by purpose-built new energy vehicles.
Standard liquid cooling systems often lack sufficient thermal dissipation capacity; they struggle to manage the massive heat generated by the high-current charging and discharging typical of heavy-duty operations, leading to thermal imbalances. In summer, inadequate heat dissipation causes temperature disparities across battery cells, accelerating degradation and even creating a risk of thermal runaway. In winter, insufficient heating capabilities can slash driving range and prevent the vehicle from starting. Furthermore, general-purpose systems often fail to align with the vehicle's existing spatial constraints and interfaces. Retrofitting requires cutting the chassis, drilling holes, and rerouting wiring-compromising the vehicle's structural integrity. This not only extends the conversion timeline and increases costs but also jeopardizes regulatory compliance and introduces safety risks such as coolant leaks and wiring harness abrasion.
For heavy-duty vehicle electrification, compatibility must take precedence over simply stacking hardware; one cannot rely solely on technical specifications. Solutions must be tailored to the vehicle's installation space, load requirements, and operating environment, utilizing integrated liquid cooling and heating systems specifically designed for heavy-duty applications. Priority should be given to non-destructive, in-situ installation that aligns with the vehicle's voltage and electronic control logic, ensuring effective thermal management through both high-temperature cooling and low-temperature preheating. Only by acknowledging the non-standard nature of these conversions-and rejecting the use of generic, one-size-fits-all solutions-can operators avoid common pitfalls and ensure reliable, long-term vehicle performance.
