Proper maintenance ensures reliable operation, extends service life, and maintains safety for battery - powered electric flat cars. Below are key condensed guidelines:
1. Battery System Maintenance
Charging Management
Use the manufacturer - specified charger and follow correct charging procedures (connect after power off, disconnect after full charge).
Avoid over - discharge (stop at ≤20% power) and over - charging (unplug immediately when full).
Charge in a well - ventilated area to dissipate heat.
Inspection & Cleaning
Check terminals for corrosion/looseness; clean with weak alkaline solution, dry, and apply vaseline.
Inspect for cracks, bulges, or leaks in the battery case-replace immediately if found.
Keep the battery surface clean and dry to prevent short circuits.
Storage Care
Store with 50% - 70% charge in a cool (10°C - 25°C), dry, ventilated area away from sunlight/flames.
Recharge every 1 - 2 months if voltage drops below the recommended level.
2. Mechanical Component Maintenance
Chassis & Frame
Regularly check for loose bolts, deformation, or cracks-tighten bolts and repair/replace damaged parts promptly.
Lubricate hinges, bearings, and moving parts to reduce wear.
Wheels & Brakes
Inspect wheels for wear/looseness; replace worn tires and lubricate axles.
Check brake pads, discs, and lines; adjust clearance and replace worn pads. Test brakes before each use.
Platform & Loading Devices
Check for cracks/deformation on the platform; repair or replace as needed.
Ensure fixing bolts, clamps, and anti - slip pads are intact-replace damaged pads to prevent sliding.
3. Electrical System Maintenance
Control System
Verify control panel buttons, switches, and indicators work normally.
Inspect wiring harnesses for damage/loose connections; secure or replace as needed.
Clean dust from controllers and sensors to avoid operational issues.
Motor & Drive System
Listen for abnormal noises/vibrations/overheating during operation-stop use and inspect immediately.
Check drive belts/chains for tightness/wear; adjust or replace to ensure efficient power transmission.
Keep the system clean of oil and debris to maintain heat dissipation.
4. Safety System Maintenance
Test the emergency stop button regularly to ensure quick power cutoff.
Clean obstacle - detection sensors and check sensitivity to avoid false alarms or missed obstacles.
Inspect anti - collision buffers for damage and replace if cracked.
Ensure safety signs are clear and visible-replace missing/blurred ones.
5. Regular Overall Checks
Conduct a full inspection (mechanical, electrical, battery systems) monthly.
Perform no - load and load test runs to check starting, braking, and steering performance.
Record maintenance results in a log to track equipment status and plan repairs.
Following these key points reduces failures, extends lifespan, and maximizes operational efficiency.
