What causes the BAIC EU5 to display motor overheating?
2 Answers
The reasons for the BAIC EU5 displaying motor overheating are as follows: 1. Excessive load: If the mechanical drive belt is too tight or the shaft rotation is not smooth, it can cause the motor to operate under prolonged overload. 2. Harsh working environment: For example, if the motor is exposed to direct sunlight with ambient temperatures exceeding 40°C, or operates in poorly ventilated conditions, it can lead to elevated motor temperature. Solutions include setting up a simple awning for shade or using blowers and fans for cooling. Additionally, it is crucial to clean oil stains and dust from the motor's ventilation ducts to improve cooling conditions. 3. Unstable power supply voltage: If the power supply voltage exceeds 10% of the rated voltage, it can cause a sharp increase in the core magnetic flux density, leading to higher core losses and resulting in motor overheating.
EV drivers are no strangers to motor overheating warnings. The BAIC EU5 displaying a motor overheating alert is primarily due to potential cooling system issues. Common culprits include insufficient coolant or water pump failure – especially problematic during hot weather or prolonged high-speed driving, which can cause motor temperatures to spike. Other possibilities include a radiator clogged with dust, malfunctioning cooling fans, or faulty temperature sensors triggering false alarms. When encountering this warning, my immediate response is to pull over safely and let the vehicle cool down, avoiding continued driving that could worsen the situation. Preventive maintenance is straightforward: check coolant levels quarterly and clean the radiator before summer driving to prevent blockages. Driving habits also play a crucial role – avoiding aggressive acceleration and maintaining steady speeds reduces motor strain. Ignoring this warning risks permanent motor damage, leading to costly repairs, potential battery lifespan reduction, and diminished driving range.
