Preventive maintenance intervals and key wear parts for electric powertrains.
Maintaining EV fleet powertrains requires a different approach compared to internal combustion engines. Here is a comprehensive checklist.
Regular Inspection Items
- Motor cooling system: Check coolant levels and inspect for leaks every 10,000 km
- Gear reducer: Inspect for abnormal noise and check lubricant every 20,000 km
- MCU connections: Verify torque on high-voltage connections every 30,000 km
- Battery thermal management: Inspect cooling plates and coolant quality every 40,000 km
Key Wear Parts to Stock
Keep inventory of commonly replaced parts including motor bearings, reducer seals, coolant pumps, and thermal sensors.
