It is possible to charge the battery while the car is idling, but the charging amount is relatively small, the charging time is long, and the charge may not be stable. Generally, this method is not recommended. Idling refers to the engine running in neutral gear without the car moving, consuming fuel while stationary. The charging duration can also be affected by other factors, such as whether high-power devices are in use inside the car, air conditioning is turned on, or external USB power is being supplied—all of which can increase charging time. Charging while idling consumes more fuel, and emissions during idling are highly polluting. Occupants should not sleep in a closed car with the air conditioning on, as incomplete combustion in the engine can produce carbon monoxide, which can accumulate to lethal concentrations inside the vehicle. If possible, it is advisable to use a dedicated battery charger for charging the car battery.

What is the body length of the Trumpchi GS4?

The dimensions of the Trumpchi GS4 are 4545mm/1856mm/1700mm and 4545mm/1856mm/1668mm, which are official data. The length of the Trumpchi GS4 refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle. The width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the supporting plane of the vehicle. The turbocharged engine of the Trumpchi GS4 has a maximum power of 124kW and a maximum torque of 265 Nm. This engine delivers a maximum horsepower of 169 and reaches its peak torque between 1700 and 4000 rpm. It features direct fuel injection technology and uses an aluminum alloy cylinder head. The engine is paired with a 6-speed automatic transmission. National regulations stipulate specific dimensions for vehicles. According to the national standard 'GB1589-89,' the total width of a vehicle does not include side mirrors. The limitation on vehicle width is intended to provide sufficient lateral clearance for overtaking in adjacent lanes. This means that, according to national standards, the significance of vehicle width data lies in ensuring enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the requirements of public road usage.

What type of battery does the Tesla Model 3 use?

Tesla Model 3 utilizes two types of batteries: lithium iron phosphate (LFP) batteries and ternary lithium batteries. Below are relevant details about the Model 3: 1. Model 3 Overview: The Tesla Model 3 is a new product in the Tesla Model X series, officially launched in the United States on April 1, 2016, at 11:30 AM Beijing time. 2. Features: The Model 3 does not use an aluminum body, so the vehicle dimensions are reduced by 20% to offset the impact of increased weight on range. The Model 3 has an estimated range of approximately 320 kilometers. It eliminates the impractical but visually striking falcon-wing doors and removes the 3-second acceleration from 0 to 60 mph, possibly also omitting the autopilot feature.

How to Diagnose Automotive Circuit Faults?

Common troubleshooting methods for automotive circuit faults: Common automotive circuit faults mainly include: open circuits, short circuits, electrical equipment damage, etc. To quickly and accurately diagnose faults, here are several common maintenance methods. Visual diagnosis method: When an automotive circuit malfunctions, sometimes abnormal phenomena such as smoke, sparks, abnormal sounds, burnt smells, or overheating may occur. These phenomena can be directly observed to determine the fault location. Short circuit method: When an automotive circuit device experiences a grounding (short circuit) fault, the open circuit method can be used for judgment. That is, after disconnecting the suspected faulty circuit section, observe whether the grounding fault still exists in the electrical equipment, thereby determining the location and cause of the circuit grounding. Open circuit method: If an open circuit fault exists in the automotive circuit, the short circuit method can also be used for judgment. That is, use a screwdriver or wire to short-circuit the suspected open circuit fault section, and observe changes in the instrument pointer or the operation of the electrical equipment to determine if an open circuit fault exists. Test lamp method: The test lamp method uses an automotive bulb as a test lamp to check if an open circuit fault exists in the circuit. Instrument method: Observe the indications of the ammeter, water temperature gauge, fuel gauge, oil pressure gauge, etc. on the automotive dashboard to determine if there is a circuit fault. For example, when the engine is cold and the ignition switch is turned on, if the water temperature gauge indicates full scale without movement, it indicates a fault in the water temperature sensor or a grounding in the circuit.

What Are the Basic Methods of Automotive Diagnosis?

Basic methods of automotive fault diagnosis: Inquire with the user about the time, symptoms, and circumstances when the fault occurred, the possible causes, and whether any repairs or disassembly have been performed. Initially determine the scope and location of the fault. Retrieve the fault code and identify the content of the fault. Based on the fault range indicated by the fault code, conduct repairs, paying special attention to whether connectors are loose or detached and whether wire connections are correct. After completing the repairs, verify whether the fault has indeed been resolved. If the fault code cannot be retrieved or if the fault content cannot be identified after retrieval, roughly determine the fault range based on the symptoms and use a method of checking the working performance of each component one by one to eliminate the fault. Currently, there are basically two diagnostic methods for automotive faults: one is the manual intuitive experience diagnostic method, and the other is the instrument and equipment diagnostic method. The instrument and equipment diagnostic method involves obtaining performance and fault information parameters of the vehicle without disassembling the assembly, comparing them with the technical condition of a normal vehicle, and providing conclusions on technical performance and faults. With the application of electronic information and computer technology in automobiles, diagnostic instruments and equipment for automotive faults are becoming increasingly sophisticated, and more advanced instruments are being used in automotive fault diagnosis. Instruments and equipment enable fast and highly accurate fault diagnosis, can detect latent faults, and can also predict the service life of assembly components.
