Why does the charger get extremely hot when charging an electric car?

The charger being very hot is abnormal. It may be due to battery issues preventing proper charging, such as battery aging or lack of water, causing the charger to overheat or even fail to switch to the green light. It's best to stop charging immediately to avoid accidents. We recommend taking the electric vehicle to a repair shop for inspection and maintenance. Below are some car battery maintenance tips: Avoid prolonged vehicle parking: The battery installed in the vehicle will self-discharge during extended periods of inactivity, so it's best to drive the car at least once a week for a minimum of 20 minutes to allow the battery to recharge while driving. Close windows before turning off the engine: The car's windows and sunroof operate using battery power, so it's advisable to close all windows before turning off the engine rather than after, or using the long-press lock button method to close windows after leaving the vehicle. Keep the battery clean and tidy: Regular inspection is an effective way to extend the car battery's lifespan. Use a professional battery terminal brush or an old toothbrush to clean dust and corrosion from the battery's positive and negative terminals. Apply petroleum jelly or grease to the contact surfaces to form a protective film.

Is Loud Noise in a New Car a Quality Issue?

Loud noise in a new car is not a normal phenomenon. It indicates an engine problem, which also falls under quality issues. Reasons for loud engine noise in a new car: Oil strainer issue: Poor sealing of the rubber ring causes the oil pump to fail in properly drawing up engine oil during operation, instead sucking in a large amount of air. This leads to insufficient lubrication in the engine system, particularly in the hydraulic valve lifters, resulting in metallic knocking sounds. If the oil strainer is clogged, it cannot properly draw oil into the engine lubrication system, causing poor lubrication. Abnormal engine speed: Most common abnormal engine noises depend on the engine's speed state. The noise may only occur during idling or low-speed operation, become chaotic at a certain speed, produce brief sounds during rapid deceleration, or appear during sudden acceleration and persist during high-speed operation.

Is Changing the Steering Wheel Considered a Modification?

Changing the steering wheel is considered a safety modification. However, it's best to switch it back during the annual inspection. Illegal Car Modifications: Modifying the car engine has always been considered illegal. While engine modifications might provide sufficient power, they can significantly impact safety and even affect the engine's lifespan. If you're pursuing speed, it's advisable to choose a performance-oriented car from the start rather than modifying it later. Considerations for Steering Wheel Modifications: Firstly, modifying to a racing steering wheel does not involve altering the vehicle's power or structure, so it's legally permissible. Secondly, changing to a racing steering wheel doesn't require filing with authorities, but it's recommended to revert to the original steering wheel during the annual inspection. From a safety perspective, modifying to a racing steering wheel is not advisable, as most racing steering wheels lack airbags, compromising safety in the event of a collision.
