CONSTRUCTION DUTY CHALLENGES
Why Construction Machinery Needs a Dedicated Thermal Strategy
The thermal architecture must follow the machine work cycle, installation envelope and jobsite conditions rather than a generic road-vehicle profile.
01 | Variable Hydraulic Loads
Digging, lifting and travel create rapidly changing battery and electrical heat loads.
02 | Low-Speed Operation
Long periods at low vehicle speed reduce natural airflow across heat exchangers.
03 | Opportunity Charging
Break-time or fast charging adds thermal demand within a short operating window.
04 | Dust, Mud & Debris
Airflow, sealing, mounting and service access must suit real construction sites.
05 | Shock, Vibration & Tilt
Components and interfaces must remain stable during impacts and uneven operation.
06 | Compact Installation
Limited envelopes require coordinated packaging and accessible maintenance points.

FREQUENTLY ASKED QUESTIONS
Construction Machinery Thermal Management FAQ
What is a thermal management system for electric construction machinery?
It is the coordinated cooling, heating and control architecture used to keep the battery and related electrical components within their required operating ranges during work, travel, charging and standby.
Why is construction machinery thermal management different from road vehicles?
Construction machines combine variable hydraulic loads, low-speed operation, restricted airflow, compact packaging, shock, vibration and dusty jobsites. The system should be designed from the machine work cycle rather than a road-driving profile.
How does fast or opportunity charging affect battery cooling?
Charging can add substantial battery heat in a short period. Charging power, duration, timing and repetition must be included in the thermal load calculation.
Can EVLINK support electric excavators and wheel loaders?
EVLINK can evaluate excavator, wheel-loader and other off-highway platforms. Final component selection depends on battery data, duty cycle, installation space and validation requirements.
Can the system communicate with the machine VCU and BMS?
CAN integration can be planned around the selected controller, communication protocol, operating states, diagnostics and control ownership.
What information is needed to start a project?
Provide machine type, operating mass, battery and voltage data, hydraulic and travel duty cycle, charging power, ambient range, dust and water exposure, available space, coolant requirements and CAN protocol.
