Why does the fan still run after the car is turned off?

The reason why the fan continues to run after the car is turned off: If the engine coolant temperature at the moment of parking is higher than the acceptable soak temperature of the engine, the vehicle's computer will automatically calculate the fan's operating speed and duration, thereby controlling the fan's operation automatically. The higher the engine temperature, the longer the fan runs after parking; when the engine coolant temperature drops below the soak temperature, the fan turns off. This mechanism protects the engine and extends its service life. More information about the car's electric fan is as follows: 1. Working principle: The car's electric fan is controlled by a thermostat. When the water temperature rises to the upper limit, the thermostat connects the power supply, and the fan starts working. When the water temperature drops to the lower limit, the thermostat disconnects the power supply, and the fan stops working. 2. Working requirements: The electric fan motor draws a large current during operation, requiring higher specifications for the wiring used.

Can the car be turned on while charging?

Electric vehicles can be started while charging. Here are the specific details about electric vehicles: 1. Concept: Battery Electric Vehicles (BEV) refer to vehicles powered by an on-board power source, using electric motors to drive the wheels, and meeting all the requirements of road traffic and safety regulations. They are started using electricity stored in batteries. Sometimes, 12 or 24 batteries are used to drive the car, while other times more may be required. 2. Types: The types of electric vehicles include Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), and Fuel Cell Electric Vehicles (FCEV). 3. Power Source: The power source provides electrical energy to the drive motor of the electric vehicle, and the motor converts this electrical energy into mechanical energy. The most widely used power source is the lead-acid battery, but with the advancement of electric vehicle technology, lead-acid batteries are gradually being replaced by other batteries due to their low energy density, slow charging speed, and short lifespan. Emerging power sources under development mainly include sodium-sulfur batteries, nickel-cadmium batteries, lithium batteries, fuel cells, and other new types of power sources.

How to Proceed with Parking Space Transaction if the Invoice is Lost?

If you intend to transfer the usage rights of a parking space, the original lease invoice must be provided during the transfer process. In case the invoice is lost, you can request a reissue from the developer by presenting relevant supporting documents. Below is an introduction to invoices: 1. Invoice: An invoice refers to a business document issued and received by all entities and individuals in the purchase and sale of goods, provision or receipt of services, and other business activities. It serves as the original basis for accounting and is also a crucial document for audit authorities and tax authorities during law enforcement inspections. A receipt, on the other hand, is proof of payment, while an invoice only confirms the occurrence of a transaction, not whether payment has been made. 2. Invoice Classification: Ordinary Invoice: Primarily used by business tax payers and small-scale VAT taxpayers, it can also be used by general VAT taxpayers when they are unable to issue special invoices. VAT Special Invoice: A product of China's new tax system, it is specifically designed by the national tax authorities for the needs of VAT collection and management, exclusively for taxpayers selling or providing VAT taxable items.

What Causes Water Leakage into Car Doors on Rainy Days?

Water leakage into car doors on rainy days is usually caused by two reasons: one is water entering while the vehicle is in motion, and the other is water entering while the vehicle is parked. There are gaps on the car body and doors, so it is inevitable for rainwater to seep into the doors during rainy days, leading to water leakage. Relevant information about car doors is as follows: 1. Introduction: A car door provides access for drivers and passengers to enter and exit the vehicle, isolates external interference, reduces side impacts to a certain extent, and protects occupants. The aesthetics of a car are also related to the design of its doors. 2. Standards for Good Car Doors: The quality of car doors is mainly reflected in their anti-collision performance, sealing performance, ease of opening and closing, and of course, other functional indicators. Anti-collision performance is particularly important because during a side collision, the buffer distance is very short, making it easy to injure occupants inside the vehicle.

What does a car ESC system malfunction mean?

When the ESC warning light illuminates, possible causes include: 1. Faulty sensors in the ESC system, such as the yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor. 2. Issues with the system's wiring, including short circuits or open circuits. 3. Malfunction of the control unit itself. Below is relevant information about the ESC system: 1. Definition: The ESC system is the Electronic Stability Control system, a new active safety system for vehicles. It primarily includes the functions of the Anti-lock Braking System (ABS) and Traction Control System (TCS), and additionally incorporates a yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor when the vehicle is turning. 2. Function: The system ensures lateral stability by detecting understeer or oversteer through signals from the steering angle sensor, lateral acceleration sensor, and wheel speed sensors. It then controls one or more wheels to apply braking, adjusting the vehicle's body posture during lane changes or cornering, making the car more stable and safe when changing lanes or navigating curves.

What Causes the Rear Air Conditioning to Stop Blowing Air?

Here are the specific reasons why the rear air conditioning may not be blowing air: 1. Valve malfunction leading to poor opening: When the plastic components of the air outlet valve age or screws come loose, preventing normal opening and closing, it can affect the airflow. You can gently pry open the valve with a tool. 2. Damaged ducts: The air ducts of car air conditioners are made of plastic and can age, crack, or wear due to interference with other components over time. Once the ducts are damaged, air will leak from the damaged areas. It is advisable to visit a 4S shop or repair shop for inspection and replacement. 3. Clogged pipes or air filter: Prolonged use of the car can lead to the accumulation of debris such as leaves, lint, and dust inside the engine, which can block the pipes and reduce the airflow efficiency of the air vents. If the air filter is not replaced for a long time, it can also decrease the airflow efficiency. In such cases, you can disassemble the pipes to clean out the debris and regularly check the condition of the air filter.
