Why Do Electric Vehicles Catch Fire Spontaneously?

1 Answers

Electric vehicles may catch fire spontaneously due to battery issues. Hot summer weather can cause batteries to overheat, leading to spontaneous combustion. Alternatively, it could be due to battery quality problems or improper charging practices during the charging process. The specific reasons are as follows: 1. Battery issues: In the scorching summer, electric vehicles perform well while driving as the cooling system is operational. However, after parking, the cooling system stops working. The high internal battery temperature from driving combined with the external high-temperature environment can cause the battery to overheat, potentially leading to spontaneous combustion. Additionally, although electric vehicles can drive in rainy conditions without issues, water must never seep into the battery. If water enters, it can cause a short circuit, leading to spontaneous combustion. 2. Quality issues: Currently, most new energy electric vehicle power battery packs are not produced by the automakers themselves but rely on battery manufacturers. Therefore, minor defects in the manufacturing process of some new energy electric vehicle power batteries may go unnoticed. These undetected power batteries may be directly installed in electric vehicles and eventually delivered to users. Over time and with usage, battery problems gradually become apparent. 3. Charging issues: Many new energy electric vehicle owners do not follow proper charging practices, such as using non-compliant charging cables or not using certified charging stations. Over time, this can damage the pure electric vehicle battery, creating safety hazards. This is actually the most common issue, as the charging duration for most pure electric vehicles is currently a concern. In summary, vehicle owners should pay attention to charging standards and use original equipment manufacturer (OEM) accessories when charging their vehicles.

What is the normal RPM range for engine idle vibration?

550-800 RPM. Engine: Internal combustion engine, also known as reciprocating piston engine. The key difference between this type of engine and external combustion engines is that its fuel burns internally. External combustion engines, where fuel burns outside the engine, are also called Stirling engines. Jet engines refer to engines that directly generate thrust by high-speed airflow ejected from nozzles, widely used as power units for aircraft. Fuel and oxidizer undergo chemical reactions in the combustion chamber to release thermal energy, which is then converted into kinetic energy of airflow in the nozzle. Electric motor. Function: The device that provides power for automobiles, determining their power performance, fuel economy, stability, and environmental friendliness.

What Causes Abnormal Noises from the Air Conditioning?

Here are the specific reasons for abnormal noises from the car air conditioning: 1. Throttle valve dirty or stuck: After the air conditioning is turned on, the compressor also starts working. Since the compressor is driven by the engine, turning on the air conditioning increases the engine load, requiring the throttle valve to open wider to allow more air intake. When the throttle valve has carbon buildup or is stuck, it can cause engine vibration and abnormal noises. 2. Air conditioning pump noise: There are two main reasons for air conditioning pump noise—the electromagnetic clutch and the bearings inside the air conditioning pump. Noise from the electromagnetic clutch is mainly caused by wear, leading to increased gaps, while noise from the air conditioning pump bearings is primarily due to insufficient lubrication. If these issues are not addressed promptly, the air conditioning pump may burn out, resulting in a loss of cooling function. 3. Improper tension of the compressor drive belt: If the drive belt is too loose, the electromagnetic clutch is prone to slipping; if the drive belt is too tight, the load on the electromagnetic clutch increases. Improper tension of the drive belt can cause abnormal noises at best and damage the air conditioning compressor at worst.

What Do the Yellow and Red Dots on Tires Mean?

Tires with a solid red dot indicate the position of maximum longitudinal vibration on the tire, meaning this spot is the heaviest, or in technical terms, the center of gravity. During rotation, tires generate vibration, and this spot is where the vibration is most pronounced. The hollow yellow dot is the opposite of the solid red dot, representing the position of minimum longitudinal vibration, meaning this spot is the lightest, known as the tire's light point. Below are some precautions for tire installation: 1. Align the valve with the heaviest point: A car's wheel consists of three parts—the tire, the rim, and the valve. The valve should be installed on the rim first, and it should align with the rim's heaviest point. 2. Align the yellow mark with the heaviest point: When assembling the tire, the position marked with yellow on the tire should correspond to the heaviest point on the rim to achieve better dynamic balance.

What sound does engine cylinder scoring make?

If there are slight signs of engine cylinder scoring, the engine will exhibit the following conditions during idle operation: 1. There is usually a tapping or knocking sound. 2. As the temperature rises, the sound becomes duller and is accompanied by engine shaking. 3. In severe cases of cylinder scoring, the engine may stall directly. Additional information: 1. Definition of engine cylinder scoring: Engine cylinder scoring refers to obvious longitudinal mechanical scratches and abrasions on the inner wall of the cylinder within the movement range of the piston rings. In severe cases, adhesive wear may occur, leading to difficulties in starting the engine or causing it to stall. 2. Causes of cylinder scoring: The root cause of cylinder scoring is the difficulty in forming an oil film between the inner wall of the cylinder and the piston rings or piston, resulting in poor lubrication or even dry friction.

What is the difference between a direct sales store and a 4S store?

The main differences between a direct sales store and a 4S store are as follows: A 4S store refers to an automotive sales service station that integrates vehicle sales, spare parts supply, after-sales service, and information feedback. It collaborates directly with manufacturers and receives support such as relevant technical information and vehicle inventory from them. On the other hand, a direct sales store is solely responsible for selling motor vehicles, and its inventory is sourced from 4S stores. Below are the detailed explanations: 1. Explanation of 4S stores: (1) A 4S store is essentially an automotive sales service shop that combines vehicle sales (sale), spare parts supply (sparepart), after-sales service (service), and information feedback (survey). (2) Due to the variety of services provided, 4S stores typically have larger premises and more staff. (3) The establishment of a 4S store receives support from the automotive manufacturer, including technical support, vehicle inventory support, and information support. At the same time, manufacturers require 4S stores to maintain a strong brand image and meet quarterly sales targets. 2. Explanation of direct sales stores: (1) Direct sales stores are solely responsible for selling vehicles and do not offer services such as vehicle registration or insurance. Therefore, they do not require large premises—just enough space to display a few vehicles. (2) The vehicle inventory of direct sales stores comes from 4S stores, which is why they are also referred to as secondary dealers. Since direct sales stores are not regulated by manufacturers, most of their inventory is sourced from 4S stores, with a small portion coming from unspecified channels. (3) Similarly, because they are not regulated by manufacturers, direct sales stores can offer lower prices than 4S stores, which is their key competitive advantage.

Pros and Cons of Buying a Car Under a Company Name

Advantages of buying a car under a company name: 1. Acts as a company asset: Vehicles purchased under a company name can serve as fixed assets for the company, helping to avoid excessive capital injection. 2. Reduces corporate income tax: Since the vehicle is part of the company's assets, all related expenses (including fuel, maintenance, repairs, etc.) can be recorded in the company's accounts, effectively lowering some corporate taxes. This is why many business owners purchase luxury cars under their company's name. 3. Lowers tax burden: The VAT invoice from the car purchase can be used to offset company expenses, saving a significant amount of money for the company. Disadvantages of buying a car under a company name: 1. Risk of being used as collateral: If the company faces debt disputes or poor performance, the vehicle, as a fixed asset, may be directly used to settle debts. 2. Complicated transfer to personal ownership: Transferring a company-owned vehicle to an individual later can be very troublesome and may require paying certain taxes. Additionally, the purchasing process is more complex.
