What are the components of an electric vehicle powertrain system?

Electric vehicle powertrain systems include fuel cell engines, electric vehicle battery systems, onboard hydrogen supply systems, power supply systems, electric drive systems, and powertrain control systems. Below is an introduction to the electric power system: Components of the electric power system: Pure electric vehicles consist of three main parts: the electric drive system, the power source system, and the auxiliary system. The electric drive system includes the controller, power converter, electric motor, mechanical transmission device, and wheels. The electric motor functions similarly to an engine in traditional vehicles, primarily converting the electrical energy stored in the power battery into kinetic energy to drive the wheels under the driver's control, or converting the kinetic energy from the wheels back into electrical energy during braking to achieve energy recovery. The controller acts like the nervous system of the human body, coordinating the control of various subsystems through a vehicle control system to achieve optimal performance. The power source system includes the battery pack and battery management system (BMS). The auxiliary system includes the auxiliary power source, power steering system, air conditioning unit, lighting devices, etc. Operation process of the powertrain system: Based on signals from the brake pedal and accelerator pedal, the electronic controller issues corresponding control commands to regulate the electric motor and manage the power flow between the motor and the power source. The auxiliary power supply system primarily provides power for power steering, air conditioning, braking, and other auxiliary devices. In addition to input signals from the brake and accelerator pedals, the steering wheel input is also a crucial signal, as the power steering system determines the vehicle's steering flexibility based on the steering wheel's angular position.

How many days is the validity period of a temporary license plate?

Temporary license plates are valid for no more than thirty days. A temporary license plate is a paper motor vehicle license plate that permits temporary road use of a motor vehicle, also known as a temporary driving license plate. It serves as a provisional vehicle driving permit issued by the local vehicle management department of the public security bureau for newly purchased vehicles before official registration. There are four types of temporary license plates: temporary plates for administrative jurisdictions, cross-administrative jurisdiction temporary plates, temporary plates for testing purposes, and temporary plates for special-type motor vehicles. The use of temporary plates is time-limited and region-specific. You can apply for a temporary license plate at the local vehicle management office under any of the following conditions: 1. When returning from the vehicle purchase location to the place of use, you need to apply for a temporary license plate at the purchase location's vehicle management office; 2. When transferring vehicle registration, after surrendering the official license plate, you need to apply for a temporary license plate at the local vehicle management office before returning to your home location; 3. For a new vehicle in the local area that has not yet obtained an official license plate but needs to be modified in another location, you must apply for a temporary license plate locally, complete the modifications, and then apply for a temporary license plate at the modification location to return to the original area; 4. When purchasing a vehicle locally and planning to travel to another location, you need to apply for a temporary license plate locally; 5. If you do not have a fixed vehicle registration and need to test the vehicle temporarily.

Can You Open the Hood and Directly Rinse the Engine with Water?

You should not rinse the engine compartment with water directly. Here are the reasons: 1. Water can easily reach the generator, which may cause it to malfunction or even become irreparable. It is advisable to cover the generator, distributor, and brake fluid reservoir with cloth or plastic bags, especially the generator and distributor. 2. If the engine is hot, rinsing it with water can cause significant damage due to thermal contraction. The engine block may crack under sudden cooling. 3. There are many electrical wires in the engine compartment, and water exposure can lead to electrical issues and accelerate wire aging. If you must clean with water, ensure proper waterproofing of critical components. It is recommended to use compressed air for cleaning instead.
