With global emphasis on sustainability, electric heavy trucks are rising in logistics. Stats show the market share will grow by over 30% in 5 years. Maintenance of their charging piles is key, as they face high power, harsh environments, and multi-model needs. Here is a guide to keep them optimal.
I. Ensuring Efficient Charging: Electrical System Maintenance
Heavy trucks have high range and tight schedule needs, requiring high-power charging to reduce downtime. This puts pressure on the electrical system, requiring meticulous maintenance.
Weekly Checks:
At least one comprehensive check of cables for damage, aging, or loose joints.

Professional Tools:
Use multimeters and clamp meters to detect current-carrying capacity.
Timely Problem Solving:
If cables heat up or soften, stop power immediately for deep inspection and replace cables if needed to ensure safety and stability.

II. Coping with Harsh Environments: Secrets of Stable Operation
Many stations are near construction sites, mines, or remote hubs with heavy dust and high altitudes.
In heavy dust, the cooling system is threatened first.
① Clean dust on radiators daily to prevent clogging and overheating.
② Use high-pressure air guns for periodic blowing to ensure air duct flow.
③ Check shell sealing and seal any gaps found.
At high altitudes, air is thin and insulation performance changes.
① Increase frequency of insulation tests for key parts using insulation resistance meters.
② Optimize the cooling system, such as increasing fan power to ensure stability.

III. Compatibility with Multi-models: Software and Hardware Key Points
Logistics fleets use diverse brands with different battery parameters and protocols.
Software: Stay tuned to technical updates of various brands and get software upgrade packages from manufacturers to optimize algorithms and fix vulnerabilities.
Hardware: Periodically check the fit between the charging gun and vehicle interface. Check for wear or deformation and ensure tight contact to avoid safety hazards like arcing.

IV. Daily O&M: Appearance and Surrounding Environment
Daily check the shell for damage from collisions common in heavy truck scenarios. Fix promptly to prevent rain or dust from entering.
Ensure operation panel buttons work well for driver convenience. Keep the surroundings clean and the foundation stable with good drainage.
Daily clean gun heads with anhydrous alcohol, and check cables for bends or internal damage from frequent plugging. Replace if the outer skin is worn to keep the link smooth.

V. Safety First: Fault Handling and Maintenance Principles
In daily O&M, these points are vital. If difficult issues occur, do not handle blindly. Contact the manufacturer or professional institutions immediately. Always prioritize safety and follow specs to keep heavy truck piles in good condition.
