Thermal Management in Off-Highway EVs – better efficiency and lifespan
Electrification has transformed the transportation landscape, and this development is increasingly extending to off-highway electric vehicles (EVs). Hybrid and fully electric-powered machines used in ports, mines, and construction sites are becoming more common, but their design presents new challenges. One of the critical aspects is thermal management, which directly affects machine performance, energy efficiency, and lifespan.
Why is Thermal Management Important?
1. Longer Battery Life and Improved Performance
The batteries in off-highway electric vehicles (EVs) are exposed to intense charging and discharging cycles, generating excess heat. Keeping the battery at an optimal temperature extends its lifespan and enhances performance. Retrofitting cooling and heating systems later can be challenging, so thermal management should be considered from the design phase.
2. Energy Efficiency and Waste Heat Utilization
Optimizing thermal management improves energy efficiency. Power surges during charging and discharging cycles can give a misleading impression of cooling system requirements. Through simulations and precise calculations, the cooling system can be correctly sized—avoiding unnecessary energy consumption.
3. Reliable Operation in Cold Conditions
Extremely cold weather can slow down battery operation and prevent charging. Effective thermal management is essential to ensure the battery remains operational. Solutions like heat pumps and electric resistors play a crucial role, especially when temperatures drop to -30°C.
4. Protecting Power Electronics and Other Components
When maintained at optimal temperatures, power electronics and other components last longer and operate more efficiently. Inverters, transformers, and drivetrains benefit from well-designed thermal management, supporting the overall functionality and lifespan of the machine.
