What is the Demand for Copper in New Energy?

New energy has a demand for copper in motors and batteries. The following is a detailed introduction to the demand for copper in new energy: New energy vehicle motors: The usage of new energy vehicles will increase comprehensively compared to traditional internal combustion engine vehicles. Their motors require a large amount of wiring internally. Currently, the majority of new energy vehicles on the market choose to use PMSM (Permanent Magnet Synchronous Motors). This type of motor uses approximately 0.1kg of copper per kW. Since the power of commercially available new energy vehicles is generally above 100kW, the copper usage for the motor alone exceeds 10kg. New energy vehicle batteries: In addition, batteries and charging functions require a significant amount of copper, leading to a substantial increase in overall copper usage. According to calculations by IDTechEX analysts, hybrid vehicles use approximately 40kg of copper per vehicle, plug-in vehicles use about 60kg, pure electric vehicles use 83kg, and large vehicles such as pure electric buses require 224-369kg of copper.

What is the reason for the simultaneous illumination of the tire pressure and ABS lights on the Volkswagen Bora?

The reasons for the simultaneous illumination of the tire pressure and ABS lights on the Volkswagen Bora are: 1. Air in the system pipelines; 2. System computer malfunction; 3. Vehicle speed sensor failure; 4. ABS wiring harness breakage. The working principle of the ABS system is: During emergency braking, the highly sensitive wheel speed sensors installed on each wheel detect wheel lock-up, and the computer immediately controls the pressure regulator to release pressure from the wheel's brake caliper, preventing wheel lock-up. The functions of the ABS system are: 1. To prevent loss of vehicle control, increase braking distance, and improve vehicle safety; 2. To enhance the overall braking performance of the vehicle; 3. To prevent wheel lock-up during braking; 4. To ensure the driver can control the direction during braking and prevent rear axle skidding.

What Causes Steering Column Module Failure?

Detailed causes and solutions for steering column module failure are as follows: Incorrect front wheel alignment: Insufficient tire pressure. Deformation or wear of the steering linkage, overly tight ball joints. Lack of oil in the steering gear, excessive meshing clearance of the steering gear's meshing pair, bearing damage, or excessive preload. It is best to use identical tires, with the minimum requirement that the two tires on the front and rear axles must be the same. Deformation of the safety steering column and flange: Breakage of front coil springs or deformation of the body or frame; bending or deformation of the left and right tie rods, excessive clearance at the hinges. Unequal spring force or excessive deformation of the two front suspension coil springs, requiring professional inspection and repair at a 4S shop. Lack of lubrication in moving parts: Excessive clearance in the ball joints of the tie rods. Lack of lubrication in moving parts. Regularly lubricate the moving parts.

Why can't the car door be opened from the outside after locking, but can be opened from the inside?

The reasons why the car door cannot be opened from the outside after locking but can be opened from the inside are as follows: Child lock is engaged: You can check if the child lock is engaged. The function of the car child lock is to prevent active and unaware children from opening the door during driving when they are seated in the rear, thereby avoiding danger. In this case, the door can only be opened by an adult from the outside after the car is parked. Triggered the safety mechanism: If the rear door of the car cannot be opened from the inside but can be opened from the outside, it is highly likely that the child lock is in effect. This happens when passengers in the rear seat trigger the safety mechanism while getting in or out of the car. Simply reset it to normal. External handle linkage rod fell off: It is also possible that the linkage rod of the external handle fell off. Just reattach it to function normally. Door opening lever cracked: If the slot for the door opening lever on the external handle is cracked, replacing it will solve the problem.

Are New Cars Fuel-Efficient or Fuel-Consuming?

During the break-in period of a new car, it may consume more fuel. Break-in period precautions: During the break-in period of a new car, prolonged continuous driving should be avoided to prevent excessive working hours of the engine and chassis components, which would increase wear and directly affect their service life. The vehicle should also avoid operating at full load; typically, within the first 1,000 kilometers, it's best to keep the load below 80% of the rated capacity. Additionally, try to avoid high-speed driving. Within the first 2,000 kilometers, full-throttle speed should not exceed 70% of the maximum speed. Methods to reduce fuel consumption: The longer the idle time when parked, the greater the fuel consumption, so minimize idle parking time. Avoid rapid acceleration, slamming on the throttle, and driving at low RPMs. Factors affecting fuel consumption: Various driving conditions such as acceleration, deceleration, braking, and engine idling, as well as load capacity, ambient temperature, and whether the air conditioning is on, all have an impact.

How Long Does It Take for a New Car to Be Delivered from the Factory to the 4S Store?

It takes a certain amount of time for a new car to arrive at the store. Generally, after the consumer places an order, the 4S store will make a plan based on the consumer's order and report it to the manufacturer. Once confirmed, the vehicle can be transported, which usually takes at least 10 to 15 days. Confirm the pickup date: The time it takes to pick up a car after purchase can vary greatly, and different vehicles may have different pickup times. Therefore, consumers must negotiate with the salesperson in advance when buying a car, ensuring the salesperson provides an approximate pickup date and includes it in the purchase contract. Only in this way can the smooth pickup of the car be maximally guaranteed. Compensation for delayed delivery: If the 4S store delays the delivery of the car after the consumer places an order and cannot provide a specific delivery time, as long as the delivery date is clearly stated in the purchase contract, the 4S store must complete the delivery within the specified period. Otherwise, the 4S store will be in breach of contract, and the consumer has the right to demand double the deposit as compensation from the 4S store.
