Table 1 Faults of electric drive systems.
From: Long and short term fault prediction using the VToMe-BiGRU algorithm for electric drive systems
Fault type | Priority | Description |
|---|---|---|
Motor Encoder Error (MEE) | High | Encoder malfunctions affecting motor speed and position accuracy. |
Battery Over-discharge (BOD) | High | Battery discharged beyond safe limits, risking permanent damage. |
Battery Pack Voltage Fault (BPVF) | High | Abnormal voltage in battery pack, impacting power supply stability. |
Motor Gear Scratch (MGS) | Medium | Scratches on motor gears affecting power transmission. |
Motor Startup Speed Abnormal (MSSA) | Medium | Abnormal speed during motor startup, indicating potential issues. |
Speed Sensor Fault (SSF) | Medium | Fault in speed sensor leading to inaccurate speed feedback. |
Hub Motor Speed Abnormal (HMSA) | Medium | Abnormal speed in hub motor, affecting vehicle propulsion. |
Gearbox GearWear Fault (GGF) | Low | Wear on gearbox gears, gradually degrading performance. |
Bearing Inner Ring Fault (BIRF) | Low | Fault in bearing inner ring, causing increased friction and vibration. |
