What causes the BAIC EU5 to display motor overheating?

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.

From a technical perspective, overheating in the BAIC EU5 motor is often related to cooling system failure. During operation, the motor generates significant heat, which is dissipated by the circulating coolant in the cooling system. Issues such as low coolant levels, water pump failure, or radiator blockage can prevent proper heat dissipation. Electrical problems, such as faulty temperature sensors or control module errors, may also cause the system to misinterpret overheating conditions. I suggest not rushing into repairs; first conduct a self-check: inspect whether the fuses are intact and check for loose wiring connections. In terms of design, electric vehicle motors have sensitive overload protection, which can be easily triggered during prolonged uphill driving or traffic congestion. Preventive measures include regular maintenance of the cooling system, cleaning the fan and heat sink, and avoiding continuous high-speed driving in summer. Poor maintenance can reduce motor efficiency and even affect overall vehicle performance. Addressing issues early can extend the motor's lifespan.

As a seasoned driver with years of experience, I've encountered motor overheating issues in my BAIC EU5. Common causes are cooling system problems, like low fluid levels or a dusty radiator. Environmental factors also play a big role—driving in hot weather can easily lead to temperature spikes. From personal experience: when a warning light appears, stop immediately and do a quick coolant check. Ignoring it could fry the motor, so I recommend heading straight to a service center. For prevention, I stick to regular maintenance to avoid risks.
