Is it okay to keep a power bank in the trunk during summer?

It is not advisable to keep a power bank in the trunk during summer. Here are specific details about items that should not be left in the car in summer: 1. Lighters: In hot summer, outdoor temperatures can reach around 35 degrees Celsius, not to mention the enclosed space inside a car, which can easily lead to explosions. 2. Power banks: When the car temperature is high, batteries left in a high-temperature environment for a long time can bulge or even explode. Therefore, car owners should avoid placing electronic product batteries such as mobile phone batteries and digital camera batteries on the top of the center console exposed to direct sunlight or on the storage shelf between the rear seats and the window.

What to Do When Bluetooth Connects to the Car but There's No Sound?

If the car Bluetooth is successfully paired but there's no sound, it may be because the phone volume or the volume of the car navigation system is not turned on. It could also be that the car system is not on the Bluetooth media audio playback interface and is still playing the last media audio source, resulting in no sound when playing music. Here is an introduction to car Bluetooth: 1. Introduction: Car Bluetooth is an in-car wireless hands-free system designed based on wireless Bluetooth technology. Its main function is to connect with a mobile phone via Bluetooth for hands-free calls during normal driving. 2. Precautions for using car Bluetooth: (1) Do not use it under strong light for too long, as this will affect the lifespan of the car Bluetooth. (2) Do not clean the device with corrosive liquids, as this will damage it. To extend its lifespan, regular protection is necessary. (3) Do not store it in excessively hot places, as high temperatures will shorten the lifespan of electronic devices, damage the battery, and cause some plastics to degrade.

How Many Years Does an Electric Car Battery Generally Last?

Electric car batteries generally last between 3 to 8 years. Here are specific methods to extend battery life: 1. Timely replenishment of electrolyte: During the use of car batteries, the electrolyte naturally evaporates and depletes. If the battery electrolyte is insufficient, it may result in a loss of power, requiring the addition of electrolyte. 2. Avoid using high-power devices when the engine is off: Frequently using in-car electrical equipment such as radios and dome lights after parking can harm the battery and shorten its lifespan. When the car is turned off, minimize the use of high-power electronic devices inside the car to prevent excessive battery drain. 3. Clean the battery: Regularly wipe the battery to remove surface dust, grease, and white acid corrosion powder, which can further extend the battery's lifespan.

What is the reason for a sudden significant drop in range mileage?

Range mileage can suddenly drop significantly due to different driving habits, as the calculation results for range mileage will also vary, and fluctuations are normal. Related information: 1. Introduction: Range mileage refers to the distance that can be traveled on a full tank of fuel. Simply put, if you fill up a 60L tank and travel 800KM, this is the range mileage. Alternatively, if you have half a tank of fuel left, a computer calculation tool can display how many more kilometers you can travel, and this figure is the range mileage. Many vehicles have this feature. 2. Notes: This is an estimated figure provided by the vehicle's instruments based on certain standards and calculations, and it may not be entirely accurate.

What Causes Engine Shaking When Starting a Car?

Engine shaking when starting a car is caused by severe carbon buildup in the engine or ignition system failure. Below is a detailed explanation of the causes of engine shaking during startup: 1. Severe carbon buildup in the engine: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the cold start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This makes the engine difficult to start. In such cases, the engine can only start easily once the carbon deposits have absorbed enough gasoline to reach saturation. After starting, the gasoline adsorbed on the carbon deposits is then drawn into the combustion chamber by the engine's vacuum suction, enriching the air-fuel mixture again. This fluctuation between lean and rich air-fuel mixtures causes the engine to idle roughly after a cold start. 2. Ignition system failure: Issues with the ignition system or poorly functioning spark plugs can also lead to such symptoms.
