What causes the power output limitation in Chery Ant?
2 Answers
Chery Ant's power output limitation may occur due to the following reasons: 1. Causes: Overheating or overcooling of the power battery will limit the power output, which is a protective measure. This is acceptable in extreme weather conditions and does not indicate a defect in the battery temperature control system. However, if the voltage difference between individual battery cells exceeds 200mv, a "small turtle" warning will appear. This is also a protective measure, but it indicates a problem that needs to be addressed. It is recommended to visit a 4S store to apply for replacement of either low-voltage or high-voltage battery cells. 2. Comparison: The appearance of the "small turtle" warning is not unique to the 726 model; it also occurs frequently in the 729 model. It has been observed in the 151 and 251 series as well, though it is more common in the 726 model. Moreover, it tends to appear shortly after use, clearly indicating poor consistency in the Jiewei batteries, likely due to inadequate grouping and capacity determination during production.
I've been driving the Chery Ant for over a year and have encountered power output limitation issues several times, feeling sluggish acceleration as if being held back. The most common situation is when the battery level is too low—the car automatically reduces power to protect the battery from discharging too quickly. During hot summer days, if the motor's cooling can't keep up, the system will limit power output. Similarly, in cold weather, the battery's efficiency drops due to low temperatures, leading to the same issue. Hardware-wise, faulty sensors misleading the system or software bugs could also trigger this. Solutions: First, check the remaining battery level and try charging it; if it's hot outside, pull over to let the car cool down before continuing; you can also restart the car to reset the system. If the problem persists frequently, take it to the shop for inspection—don't delay, safety comes first. Experience tells me that understanding your car's condition can reduce trouble.
