Is the Fuel Level Displayed on Haval Smart Home Accurate?
2 Answers
Haval Smart Home displays the fuel level accurately. Pointer indication deviation: When the fuel pump is working, a negative pressure is created inside the fuel tank, which reduces the corresponding fuel tank volume and raises the fuel level. Additionally, the thermal expansion effect of gasoline due to temperature naturally causes the display to be higher. When the temperature drops and the fuel tank is opened, the pressure is released, and the fuel level subsequently drops. Therefore, the display deviation is a normal phenomenon. However, the deviation generally does not exceed the width of one pointer. Do not continue driving after the indicator light comes on: When the indicator light comes on, it indicates that the fuel level is too low. Continuing to drive at this point can be harmful because the fuel pump is located inside the fuel tank and generates a significant amount of heat during operation. Fuel acts as its coolant, continuously cooling the fuel pump to ensure its proper functioning. Without the cooling effect of the fuel, prolonged operation of the fuel pump will inevitably cause it to burn out.
As a long-time Haval owner, I find the fuel level displayed by Haval Smart Home is generally reliable, though occasional discrepancies occur. It mainly depends on how the fuel level sensor works - this float-type sensor inside the fuel tank estimates fuel volume based on float position, but readings can be affected by bumps or temperature changes. For instance, when driving on bumpy mountain roads once, the display showed a sudden significant drop that was actually the float's misjudgment. Software delay is another issue - the system might not immediately update after refueling, sometimes requiring an app restart. I've developed the habit of manually verifying the reading before each trip to avoid sudden low-fuel warnings mid-drive, as this concerns driving safety and shouldn't be taken lightly. Overall, it's accurate 99% of the time, but developing a routine of cross-checking with the physical dashboard provides extra assurance.
