Reasons why a new energy vehicle cannot be charged slowly: 1. The fuse inside the battery is broken, in which case only the fuse inside the battery can be replaced; 2. Poor contact, including many aspects, such as poor contact between the fuse tube and the fuse seat, poor contact between the plug and the socket, poor contact between the charger and the power source, etc., which will affect the normal charging of the electric vehicle, resulting in the battery not being charged or not being fully charged; 3. Poor contact of the plug-in inside the battery: mainly due to problems with the connection between the positive and negative poles of the battery, you can try re-plugging or replacing the wire; 4. The battery has exceeded its service life: the normal battery life is about 5 years, but if there are often incorrect charging methods, it will cause the battery to fail prematurely, and the solution is to replace the battery.

Last time I went camping, I ran into the trouble of slow charging not working, and it took me a while to figure it out. The most likely issue is that the charging gun wasn't inserted properly—you need to hear a click for it to lock in place. Another possibility is that the cooling fan of the onboard charger was clogged with mud or sand, causing overheating and triggering the automatic power-off protection. Or, your home power socket might have poor grounding—new energy vehicles have high grounding requirements, so try testing the ground wire with a voltage tester. The battery temperature being too high or too low can also cause charging to stop; in summer, temperatures above 50°C or in winter, below freezing, won't work. If you forgot to turn off the scheduled charging function in the car's system, it might show a charging failure—check the charging settings on the central control screen. Lastly, the metal contacts in the charging port might be oxidized; just clean them with a cotton swab dipped in alcohol. If none of these fixes work, you'll probably need to visit a 4S shop to check the wiring.

Is Replacing Engine Connecting Rods a Major Issue?

Replacing engine connecting rods is not a major issue and has minimal impact on the vehicle. Below are specific details about engine connecting rods: 1. Principle: The working principle of connecting rods involves using hinges and sliding mechanisms to interconnect components, enabling motion transformation and power transmission. Connecting rods can fulfill various motion trajectory requirements and facilitate conversions between different motion forms. Planar linkage mechanisms are widely used in machinery, instruments, and electromechanical products. 2. Structure: The connecting rod body consists of three parts—the small end connects to the piston pin, the big end connects to the crankshaft, and the rod section linking the small and big ends is called the connecting rod shank.

What is the name of the gear shifting position?

The lever used for shifting gears is called the handbrake, and its professional term is the auxiliary brake. Below are specific details about the handbrake: 1. Introduction: The professional term for the handbrake is the auxiliary brake. Unlike the principle of the main brake, it uses a steel cable connected to the rear brake shoes to brake the vehicle. Long-term use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the handbrake's travel will also increase. 2. Composition: It consists of a brake lever, cable, brake mechanism, and return spring, acting on the drive shaft or rear wheel brakes to achieve vehicle stability.

How to Solve Abnormal Noises in Car Engine?

Car engine abnormal noises may be caused by the following reasons and solutions: 1. Reason: Engine mount aging or loosening. The engine mount, which connects the car body and the engine, plays a role in fixing the engine. Once the mount ages or loosens, the engine will produce abnormal noises. Solution: Replace the mount. 2. Reason: Piston slap. If the car makes a clanking noise, it indicates poor lubrication conditions, and the piston collides with the cylinder wall during engine operation. Solution: Replace the engine oil. 3. Reason: Dirty throttle or excessive carbon deposits in the fuel injector. Solution: Remove engine carbon deposits, clean the throttle, and replace the oil pad and spark plugs.
