The reasons for lithium battery explosions are as follows: 1. Long-term overcharging of the battery cell: Under prolonged charging conditions, overcharging and excessive current can also lead to high temperature and high pressure, creating potential hazards. Lithium batteries may discharge instantaneously under special temperature, humidity, or poor contact conditions, generating a large current and causing spontaneous combustion or explosion. 2. Battery short circuit: When a phone is in a high-temperature state or subjected to impacts, metal friction, etc., it may cause a battery short circuit, leading to an explosion. 3. Charging-induced battery explosion: Playing with the phone while charging prolongs the charging time. Extended charging can cause the phone's temperature to rise, making it more prone to explosion.

What is the Principle of Hybrid Electric Vehicles?

The working principle of hybrid electric vehicles is as follows: 1. At the beginning of the vehicle's operation, the battery is fully charged, and its energy output can meet the vehicle's requirements. The auxiliary power system does not need to work. When the battery level drops below 60%, the auxiliary power system starts. 2. When the vehicle's energy demand is high, both the auxiliary power system and the battery pack provide energy to the drive system. When the energy demand is low, the auxiliary power system not only supplies energy to the drive system but also charges the battery pack. Below is an introduction to the concept of hybrid electric vehicles: Hybrid electric vehicles combine fuel (gasoline, diesel) and electric energy, utilizing an electric motor as an auxiliary power source to drive the vehicle. This represents a complementary technology that can also be considered as integrated innovation.

How to Read Spark Plug Heat Range?

Spark plug heat range is indicated by numbers, which are typically located in the middle of the model number. For example, in the model BP5ES11, the number 5 represents the heat range of this spark plug. Different brands have varying heat ranges, and each brand's heat range corresponds to specific vehicle models. More details about spark plug heat range are as follows: 1. The heat range of a spark plug essentially refers to an indicator of its heat absorption and dissipation capabilities. Higher-revving engines require spark plugs with higher cooling heat ranges. 2. Heat ranges are categorized into numbers 1 through 9, where 1-3 indicate low heat range, 4-6 medium heat range, and 7-9 high heat range. Most passenger car spark plugs fall within the 5-7 range.

How Often Should Car Belts Be Replaced?

Car belts are divided into engine belts and timing belts, which generally need to be replaced every 2 years or after driving approximately 60,000 kilometers. A broken belt can lead to failures such as the air conditioning system malfunctioning, power steering system failure, and power generation system failure. Therefore, timely replacement is necessary. Below is an introduction to the installation tension of belts: (1) If the belt is installed too tightly, the excessive tension can cause the belt to break easily. (2) If the belt is too loose, it may slip, causing timing lag. This can result in car shaking, poor acceleration, insufficient power, increased fuel consumption, and even tooth jumping under heavy engine load or power impact. (3) The belt should be adjusted to the optimal tension (with 10mm of give when pressed down and able to flip 90°). This ensures the belt's best performance and can extend its lifespan to some extent.

Do You Need to Keep Pressing the Accelerator While Driving?

Whether you need to keep pressing the accelerator while driving depends on the road conditions. Here are the details: 1. While driving, if there is no need to slow down or stop, your right foot should continuously press the accelerator pedal (if the vehicle has electronic cruise control, you don't need to press the accelerator pedal continuously after activating it). 2. If you need to slow down or stop, your right foot should move away from the accelerator pedal and, if necessary, press the brake pedal. If you are preparing to stop, your right foot should move away from the accelerator pedal and then press the brake pedal. After coming to a complete stop, if you don't intend to turn off the engine, there's no need to press the accelerator pedal, as the engine will automatically idle.

Does the Honda Vezel Have Anti-Collision Beams?

Honda Vezel is equipped with front and rear anti-collision steel beams. The front protection structure consists of a bumper cover, a secondary buffer layer, and a metal beam with energy-absorbing boxes. The secondary buffer layer features a two-stage design, distributed on both sides of the front end. The metal buffer layer is welded to the front bumper, adopting a design style similar to models like the Fit and Elysion. Below is an introduction to the Honda Vezel: 1. The Honda Vezel is the first SUV under GAC Honda, developed on Honda's new vehicle platform. As the third global strategic model introduced by GAC Honda following the Accord and Fit, it represents a significant milestone. 2. The Vezel not only showcases the powerful capabilities of Honda's FUNTEC technology but also embodies the brand proposition of "Ultimate Smart and Stylish." With five disruptive highlights—diamond-like versatile exterior, ultra-dynamic all-around driving control, aviation-style dream cockpit, versatile flexible space, and humanized intelligent configurations—it comprehensively breaks traditions and delivers consumers an unprecedented trendsetting experience.

Is a 6-speed dual-clutch transmission considered an automatic transmission?

6-speed dual-clutch transmission is a type of automatic transmission structure. Car transmissions can be divided into two main categories: manual transmissions and automatic transmissions, which correspond to the difference between manual and automatic transmissions. Automatic transmissions can be further subdivided into four types: AT (automatic transmission), AMT (semi-automatic transmission), DCT (dual-clutch transmission), and CVT (continuously variable transmission). More details are as follows: 1. The so-called dual-clutch transmission is essentially a car transmission with two sets of clutches. In terms of classification, dual-clutch transmissions can be broadly divided into wet dual-clutch transmissions and dry dual-clutch transmissions. Currently, mainstream dual-clutch transmissions generally have either 6 or 7 gears. A 6-speed dual-clutch transmission is one that has 6 forward gears. 2. The characteristic of a wet dual-clutch transmission is that it consists of two sets of multi-plate clutches, one large and one small, installed coaxially together in a sealed oil chamber filled with hydraulic oil. Therefore, the wet clutch structure offers better adjustment capability and higher thermal tolerance, enabling it to transmit relatively large torque. 3. The dry dual-clutch transmission was developed by simplifying the related hydraulic system based on the wet dual-clutch transmission. Since the clutch is not installed in a sealed oil chamber, the dry friction plates on the driving disc can directly engage with each other, resulting in more direct transmission efficiency. However, the drawback is that it is more prone to overheating.
