Does a 48V Hybrid System Need to Be Charged?

1 Answers

07/30/25 12:32am
48V hybrid systems do not require charging. When the vehicle does not need high power from the engine, part of the engine's power is used to generate electricity and store it in the battery. Additionally, the kinetic energy reduced during vehicle deceleration and braking is converted into electrical energy and stored in the battery. The electrical energy stored in the battery is fully utilized as driving force during vehicle operation, reducing fuel consumption while enhancing power. A hybrid system is essentially a traditional gasoline or diesel engine combined with another energy-based power system. Currently, the most commonly used is the oil-electric hybrid system.

What to Do When the Wiper Stops in the Middle?

The solutions for a wiper stopping in the middle are as follows: 1. Check the wiper blade: If you usually neglect the maintenance of the car's wiper blades and find they are severely damaged and unable to function properly, promptly replace a set of wiper blades. 2. Check the wiper motor: Open the car's hood to see the wiper motor. You can touch the wiper motor by hand. If it feels hot, it indicates an internal short circuit, and the motor should be replaced. 3. Check the wiper linkage: The wiper linkage has many connection points. If these points have issues, the wiper won't work properly. You can observe the wiper's operation to determine if it's a linkage failure. 4. Check the wiper fuse: To protect the car's wiring, each electrical device has a fuse. If the wiper doesn't work, check if the wiper fuse is blown and replace it with a spare fuse from the car. 5. Check the wiper switch: Although the wiper switch isn't used frequently, car electronics can be unstable. If no issues are found in the above checks, consider that the wiper switch might be faulty. Use a multimeter to test the switch or replace it with a new one for testing. 6. Check the wiper wiring: Inspecting the wiring is a complex and time-consuming task. You need to be proficient in using a car multimeter to measure voltage, resistance, and current, and combine this with practical experience to identify the wiring fault causing the wiper to malfunction.

What are the two common structural types of oil pumps?

There are two common structural types of oil pumps. Below are the specific introductions to these common structural types of oil pumps: 1. Gear-type oil pump: The oil pump housing is machined with an inlet and an outlet. Inside the oil pump housing, there is a driving gear and a driven gear. There is a very small gap between the gears and the inner wall of the housing. The working principle is that when the gears rotate clockwise, the volume of the inlet chamber increases as the gear teeth move away from the meshing direction, creating a certain degree of vacuum. The lubricating oil is then drawn from the inlet and fills the inlet chamber. The rotating gears carry the lubricating oil between the teeth to the oil chamber. As the gear teeth enter the meshing state, the volume of the outlet chamber decreases, increasing the oil pressure. The lubricating oil is then delivered to the engine oil passage through the outlet. 2. Rotor-type oil pump: The oil pump housing contains an inner rotor and an outer rotor. The inner rotor is fixed to the driving shaft with a key, and the outer cylindrical surface of the outer rotor fits with the housing, with a certain eccentricity between them. The outer rotor is driven by the inner rotor to rotate. The housing is equipped with an inlet pipe and an outlet. The working principle of the rotor-type oil pump is that during the rotation of the inner and outer rotors, the tooth profile of each tooth of the rotors always forms point contact with each other, creating four enclosed working chambers between the inner and outer rotors. Since the outer rotor always rotates slower than the inner rotor, the volumes of these four working chambers continuously change.

Can a car be maintained outside of a 4S shop?

It is possible to maintain a car outside of a 4S shop. There is no national regulation requiring maintenance to be performed at a 4S shop, but it must be done at a legitimate business, and there must be proof that the replaced parts are safe and reliable. This approach can save money without worrying about voiding the warranty. Daily car maintenance is very important; neglecting it can not only cause unnecessary damage to the vehicle but also endanger driving safety. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of a car, also known as car servicing. Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance scopes. The purpose of car maintenance is to keep the car clean, ensure normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life.
