What is BYD's Battery Replacement Policy?

BYD's new energy vehicle core components come with a warranty period of 8 years or 150,000 kilometers, while the power battery cells are covered by a lifetime warranty. When the battery's power degrades by 20%, customers can apply for a free replacement. Below is more related information: Reasons behind BYD's new policy: 1. As a company that started with batteries, BYD's electric vehicles have inherent advantages. Although the world is pushing for the development of electric vehicles, it must be said that there are still many technological challenges to overcome. Among these, battery power degradation and driving range are the most concerning factors for the public. To address these concerns, BYD introduced its battery replacement policy to alleviate consumer worries. 2. BYD's ability to launch such a generous policy is largely due to its rapid development in recent years. Technologically, BYD has a long history of expertise, particularly in battery technology, which has allowed it to quickly surpass other domestic automakers in the new energy vehicle sector and closely follow international leaders like Tesla. BYD's confidence in introducing this policy reflects its belief in vehicle quality. If the quality were subpar, the cost of large-scale battery or motor replacements and warranties would be unsustainable for BYD.

I bought a BYD Han EV last year and specifically researched their battery policy. The first owner gets an 8-year or 150,000 km warranty on the battery pack, with lifetime warranty on battery cells - that's genuinely generous. If the battery capacity drops below 70% during the warranty period, the manufacturer replaces it for free. The service center technicians said they use professional equipment to test battery health and only replace if it meets the criteria. But I should mention that battery damage caused by scraping the undercarriage isn't covered, so be careful when driving over potholes. The resale value of electric cars is directly tied to battery condition, so this policy is like buying long-term insurance.

Can Modified Interior Pass the Annual Inspection?

Vehicle interior modifications can pass the annual inspection. Below is relevant information about vehicle annual inspections: 1. Introduction: Vehicle annual inspection refers to mandatory testing required for all vehicles that have obtained official license plates and registration certificates. It is equivalent to an annual physical examination for vehicles conducted according to the "Technical Conditions for Motor Vehicle Operation Safety." Vehicle annual inspections help promptly eliminate potential safety hazards, encourage enhanced vehicle maintenance, and reduce the occurrence of traffic accidents. 2. Inspection Content: Check whether the engine, chassis, body, and auxiliary equipment are clean, complete, and functional; whether the paint surface is uniform and aesthetically pleasing; whether major assemblies have been replaced and match the initial inspection records; verify whether the vehicle's braking performance, steering operation, lighting, exhaust, and other safety features comply with the "Technical Conditions for Motor Vehicle Safety Operation" requirements; inspect whether the vehicle has undergone modifications, redesigns, or alterations, and whether the registration certificate, license plate, and vehicle records match the actual vehicle condition, including any changes, and whether approval and modification procedures have been completed.

How Long Can China V Vehicles Remain in Use?

They can remain in use until at least 2031. Below is relevant information about China V standards: 1. Overview: China's fifth-stage motor vehicle pollutant emission standards, abbreviated as 'China V standards,' have emission control levels equivalent to Europe's currently implemented Euro 5 emission standards. The EU has been enforcing these standards since 2009, imposing stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Each upgrade from China I to China IV has reduced single-vehicle pollution by 30% to 50%. 2. Comparison with China IV standards: Compared to China IV standards, the new standards reduce nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Based on Shanghai's annual vehicle registration volume of approximately 350,000 units, it is estimated that annual new vehicle additions could reduce nitrogen oxide emissions by about 1,000 tons. Additionally, China's China V emission control levels are equivalent to Europe's currently implemented Euro 5 standards.

What are the common causes of car body shaking?

Common causes of car body shaking are as follows: 1. Unstable oil pressure: Abnormal fuel pump supply pressure or incorrect readings and poor performance of the intake pressure sensor can cause body shaking. Solution: Check the oil pressure and replace components if necessary. 2. Aging engine components: Car shaking can also be related to worn engine mounts. Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and cabin, causing shaking at idle. Solution: Replace the components. 3. Severe engine carbon buildup: Dirty throttle body or excessive carbon deposits in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector can be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. Solution: Clean the fuel system and check if the idle control valve has carbon deposits that need cleaning.

What are the mandatory insurances for sedans?

The mandatory insurances for sedans are as follows: 1. Compulsory Traffic Accident Liability Insurance (CTALI): CTALI is mandatory by the state, and without it, you cannot even get a license plate, so it must be purchased. However, due to the limited coverage and compensation of CTALI, supplementary commercial auto insurance is necessary. 2. Third-party Liability Insurance: This refers to the maximum amount the insurance company will pay in the event of an accident. It compensates for property damage and personal injuries caused to a third party, serving as a supplement to CTALI. 3. Vehicle Damage Insurance: While CTALI and Third-party Liability Insurance cover compensation for others, Vehicle Damage Insurance covers compensation for your own car. For example, repair costs incurred after an insured accident, including daily collisions, scratches, and damages caused by falling objects or various natural disasters, even losses incurred during ferry transport, as long as they fall within the coverage of Vehicle Damage Insurance, can be claimed. Moreover, the coverage of Vehicle Damage Insurance has become more extensive than before.

Can a 6-point deduction for running a red light be handled on the Traffic Management 12123 app?

Running a red light resulting in a 6-point deduction can be handled on the Traffic Management 12123 app. However, due to variations in law enforcement and management across different regions, if the app prompts the owner to visit a service window for processing, the owner must then go to the local traffic police station or vehicle management office to handle the violation. The scope of violations that can be processed on the Traffic Management 12123 app includes: those recorded by traffic monitoring equipment; single fines not exceeding 200 yuan; and where the total penalty points for the violation and the driver's accumulated points do not exceed 12. Under the above conditions, drivers can also use the platform to self-process non-scoring traffic violations for vehicles not registered under their name. Additionally, for on-the-spot penalties issued by traffic police under simplified procedures, drivers can pay the fines through the Ministry of Public Security's Traffic Management Service Internet Platform. To pay a traffic fine on the Traffic Management 12123 app, select the unpaid violation under 'Violation Processing,' then click 'Process and Pay' at the bottom. The general procedure for traffic violation penalties includes: investigation and evidence collection, notification of the penalty details, reasons, basis, and relevant rights, hearing statements or defenses or holding a hearing, and making a penalty decision.
