As an automotive technology enthusiast, I'm thrilled to delve into the powertrain systems of new energy vehicles. The power primarily comes from battery packs and electric motors, unlike traditional fuel-powered cars that rely on combustion engines. When you start the vehicle, the battery supplies direct current, which is converted to alternating current by the controller to drive the motor, propelling the wheels. The entire process offers rapid response, linear acceleration without jerking, delivering an exceptionally smooth ride. A related topic is range anxiety—battery energy density determines how far you can go, with current mainstream lithium-ion batteries offering approximately 300-500 km per charge, though performance may drop in cold temperatures. Charging is crucial, ranging from slow charging via household sockets to fast-charging stations that can replenish 80% in half an hour. Regenerative braking recovers energy, boosting efficiency, but battery lifespan management shouldn't be overlooked—regular check-ups are recommended to extend service life. This powertrain design is highly efficient and eco-friendly, forming the cornerstone of future mobility.

Is there a charge for checking the tire pressure warning at a 4S shop?

If the tire pressure warning light is on due to an increase or decrease in tire pressure, there should be no charge for visiting a 4S shop. They will only need to adjust and supplement the tire pressure and reset the tire pressure warning light. However, if the tire pressure warning light is on due to a malfunction, eliminating the warning light will require repairs by the 4S shop, and these repairs will incur a charge. Abnormal tire pressure can be caused by the following reasons: Abnormal tire pressure: Generally, the system will alert if the pressure is below 1.8 bar or above 3.0 bar. In such cases, a tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will continue to record the previous data, causing the tire pressure monitoring indicator light to remain on. In this case, simply resetting the tire pressure monitoring system will suffice. Damaged tire pressure sensor: The tire pressure sensor, which is used to monitor tire pressure, is installed directly inside the tire and connected to the tire inflation valve. If the tire pressure sensor is damaged during driving, such as by hitting an object, the tire pressure fault light will also illuminate. For sensor damage issues, the only solution is to replace it with a new component.

Do I need to replace my vehicle license?

Car license needs to be replaced under the following circumstances: 1. Annual inspection expired: The car license was not inspected when it expired, and the annual inspection validity of the previous year has expired. Failure to conduct the annual inspection on time means the vehicle has not passed the required annual or biennial inspection. Vehicles without a valid annual inspection cannot be driven on the road, and driving without it will result in penalties, hence the need for replacement. 2. The validity of the main license has expired: This expiration is equivalent to not having a license. Vehicles without a valid license cannot be driven on the road and will face corresponding penalties, thus requiring replacement.

What brand is alken tires?

alken tires are from the Cooper brand. The tire size is 225/65R17. Cooper Tires, with nearly a century of history, is the second-largest tire manufacturing enterprise in North America. Cooper Tire holds a leadership position in the global tire replacement market. Currently, its tire sales rank as the eighth largest in the industry worldwide. When using alken tires in daily life, pay attention to the following points: Regularly inspect the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves on tires gradually become shallower. If the tread pattern wears out, it loses its drainage and anti-slip functions, significantly reducing the vehicle's performance. Small cracks may seem minor but can lead to tire blowouts at high speeds. Additionally, promptly remove pebbles lodged in the grooves. Try to park on flat ground. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that can deteriorate rubber. After parking, avoid turning the steering wheel, as this action accelerates tire wear. Do not splash water for cooling. In hot weather or during high-speed driving, tires can overheat, and the air pressure may increase. In such cases, stop to allow the tires to cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent use of brakes and sudden stops to prevent accelerated tread wear caused by dragging between the tires and the ground.
