It is covered under the Three Guarantees, and you can request a battery replacement. Introduction to Car Batteries: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, the term 'battery' refers to a lead-acid battery, which is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. Battery Maintenance: Avoid parking the car in an open-air parking lot for extended periods. If the car is to be parked for a long time, the battery should be removed and taken away to prevent it from freezing and getting damaged. Car batteries need to be charged regularly. If left unused for a long time, the battery will gradually discharge on its own until it becomes unusable. Therefore, the car should be started periodically to charge the battery. Avoid using car electrical appliances after the engine is turned off. Using the battery alone when the engine is not generating power can cause damage to it.

I once encountered a swollen battery. It happened just one year after buying the new car, and I was really anxious. I immediately took it to the 4S store for inspection, and they found it was due to an internal battery defect. They replaced it with a new one for free. Whether a swollen battery is covered by the warranty depends on the cause. The warranty policy covers product quality issues. If the swelling is caused by the battery's own defects during the warranty period, such as electrolyte leakage or manufacturing problems, it must be repaired or replaced for free. However, if it's due to frequent overcharging, high-temperature environments, or improper use causing damage, it's not covered by the warranty. It's best to take the car to the store for inspection immediately and get a diagnostic report before discussing compensation. For regular maintenance, avoid leaving the battery charging for too long, especially during hot summer days. Keeping it well-ventilated can reduce risks. A swollen battery is prone to overheating and catching fire, so safety first—don't tamper with it.

Can the air conditioning be turned on when a new energy vehicle is turned off?

New energy vehicles can turn on the air conditioning after being turned off. However, there is no cooling function, and prolonged use can easily lead to battery drain. Therefore, it is not recommended to keep the air conditioning on for a long time while the vehicle is turned off. If you need to ventilate, you should switch to the external circulation mode to allow fresh air to enter the car. Common misconceptions about using car air conditioning: 1. Smoking in the car with the air conditioning on: Some people turn on the air conditioning and smoke in the car while resting or waiting, which is harmful to the health of the occupants because the doors and windows are closed, and the smoke cannot escape, naturally irritating the eyes and respiratory system. Therefore, turning on the air conditioning while parked is harmful in itself, and if you must smoke in the car, be sure to adjust the air conditioning ventilation control to the "exhaust" position. 2. Always using the internal circulation mode: Some car owners keep the air conditioning switch in the internal circulation position, which is not ideal. The air conditioning mode should be adjusted according to temperature and environment. The internal circulation system can be used, but not for extended periods. When the air conditioning is first turned on, it's best to use the external circulation mode first and then switch to internal circulation after the temperature drops. 3. Arbitrarily choosing the air conditioning temperature: Car owners often select different temperatures "to stay cool," but when the indoor temperature remains too low for a long time, the body's endocrine system may struggle to adjust, leading to illness. Setting the indoor temperature below 20°C can cause various discomforts.

What Causes Soft Brakes in a Car?

Brake softness can be attributed to the following reasons: 1. Poor performance of brake fluid, resulting in insufficient friction between the brake pads and brake discs. 2. Over time, moisture can seep into the system. After the moisture evaporates, a certain amount of air gap forms between the brake pads and brake discs, leading to the phenomenon of soft and ineffective brakes. Self-adjustment methods for soft brakes: 1. Start the car and wait for the idle speed to stabilize (approximately 2-3 minutes). 2. Press the brake pedal firmly all the way down, applying strong force. 3. After two seconds, pull up the handbrake while keeping the foot brake pressed firmly for several seconds. 4. Then slowly release the foot brake and finally release the handbrake to complete the adjustment.

What materials are used in Tesla batteries?

Tesla models currently use NCA (Nickel Cobalt Aluminum) type batteries. Here is an introduction to Tesla batteries: 1. The common ratio of nickel, cobalt, and aluminum in NCA batteries is 8:1.5:0.5. The aluminum content is very low, making it close to a binary material. Aluminum (a transition metal) replaces manganese, modifying lithium nickel cobalt manganese oxide through ion doping and surface coating. Ion doping enhances material stability and improves cycle performance. However, during production, because aluminum is an amphoteric metal that is difficult to precipitate, the manufacturing process of NCA materials presents challenges. Nickel-cobalt-aluminum batteries require high manufacturing precision and are costly, but aluminum helps improve the chemical stability of battery cycles. 2. Within the ternary system, nickel content can be increased to achieve higher battery energy density. However, the nickel-cobalt-aluminum crystal structure is less stable than nickel-cobalt-manganese, making it prone to collapse at high temperatures, leading to thermal runaway. Additionally, excessively high pH levels can cause cell swelling, posing risks. Overall, Tesla's ternary lithium batteries are currently popular, with most pure electric vehicles using them. Lithium batteries are lighter and have higher energy density, making them highly suitable for pure electric vehicles.

How to Check Tire Pressure on Trumpchi GS4?

Trumpchi GS4's tire pressure monitoring can be viewed on the dashboard. The vehicle comes equipped with a tire pressure monitoring system that provides automatic alarm alerts, requiring no manual operation. Normal tire pressure range: According to the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5bar. Methods for adjusting tire pressure: When the vehicle is unloaded or partially loaded, it is advisable to adjust the tire pressure to the lower limit of the standard value. When the vehicle is fully loaded, the tire pressure should be adjusted to the upper limit of the standard value. For new tires, the tire pressure should be increased by approximately 0.2bar above the standard tire pressure. For old tires, the tire pressure should be appropriately reduced according to the standard; if the wear is severe, adjust to the lower limit of the standard tire pressure. For comfort-oriented soft tires, the standard tire pressure can be increased by about 0.2bar. For performance-oriented hard tires, adjust to the lower limit of the standard tire pressure.
