Can a 48V be upgraded to 72V without changing the motor?

No, if the original battery of an electric vehicle is 48V, adding two more batteries to make it 72V will definitely require replacing the controller and the motor. Without changing the controller, it won't function, and if the motor isn't replaced, the coils will burn out. 1. If the "motor is not replaced" and remains at 48V, under 72V, the load current will surge due to overvoltage, and the excessive current will burn out the controller. At the same time, the 48V motor will also be damaged by the overvoltage. 2. The "rated operating voltage" of the motor is crucial and is a necessary condition for the safe operation of the motor. For example, the rated operating voltage of a household air conditioner is 220V, and arbitrarily increasing the voltage is clearly unwise.

Is it necessary to clean the throttle frequently?

The cleaning of the throttle is very necessary. More information about cleaning the throttle is as follows: 1. A dirty throttle can cause inflexible movement of the throttle, allowing air entering the engine to carry many impurities, affecting the normal combustion of gasoline, reducing the engine's working power, and in severe cases, leading to unstable idling, difficulty starting, and decreased power. 2. Clean the throttle every 20,000 to 40,000 kilometers. If the driving environment is harsh, this cleaning interval should be shortened. 3. Excessive cleaning of the throttle can lead to premature scrapping of the throttle. Frequent cleaning gradually removes the special coating inside the throttle's inner chamber, making it easier for oil and dirt to adhere without the protective coating.

What are the warning signs of a CVT transmission failure?

CVT transmission failure warning signs include the engine speed increasing when the accelerator is pressed, but the vehicle's acceleration feels weak. Another symptom is noticeable jerking when the vehicle is driving normally at speeds above 30 km/h. At this point, pressing the accelerator pedal does not increase the vehicle's speed, which can only be maintained at around 4 km/h. The CVT transmission, also known as the continuously variable transmission, differs from conventional transmissions in that its gear ratio is not fixed but varies continuously and linearly. The CVT transmission provides excellent fuel economy, smooth driving, and effectively reduces emissions. However, the issue is that it can experience slipping when the load is too heavy.
