Bleeding method after adding brake fluid: The air bleeding operation requires coordination between two people. One person continuously presses the brake pedal inside the vehicle to raise its position and holds it steady without releasing. Meanwhile, another person underneath the vehicle loosens the bleeder valve to allow air and brake fluid in the pipeline to discharge together. When the pedal position drops, immediately tighten the bleeder valve. Repeat this process multiple times until no air bubbles are discharged from the plastic tube, then tighten the bleeder valve and install the dust cover. Brake fluid, also known as hydraulic brake fluid, should be purchased from reliable manufacturers, and the higher the grade, the better. All liquids have the characteristic of being incompressible. In a sealed container or a liquid-filled pipeline, when the liquid is under pressure, it quickly and uniformly transmits the pressure to all parts of the liquid. Hydraulic braking works based on this principle.

What are the solutions for a dim reversing camera light?

The solution for a dim reversing camera light is to install some additional LED lighting bulbs around the reversing camera. The reversing camera, also known as a parking assist system, reversing visual system, or onboard monitoring system, captures real-time images of the area behind the vehicle through a rear-mounted camera and displays them on the central control screen. This allows the driver to observe the situation behind the vehicle and enhances parking safety. The meanings of the auxiliary lines in the reversing camera are: 1. The red line indicates a warning zone, where obstacles are approximately 30 cm from the rear of the vehicle—this is the optimal stopping point; 2. The yellow line indicates a caution zone, where obstacles are about 60 cm away—drivers can continue reversing but should slow down and monitor the distance; 3. The green line indicates a safe zone, with obstacles roughly 2 meters away—drivers can reverse freely within this range.

What Documents Are Required for Applying for a Home Charging Station?

To apply for a home charging station, you need to provide a copy of your ID card, the New Energy Passenger Vehicle Charging Conditions Confirmation Letter, proof of property management approval for installation, and proof of parking space ownership. Below are the factors to consider when installing a home charging station: Whether installation conditions are met: Before installing a charging station, users need to inspect their parking space to determine if it meets the installation requirements. The key issue is whether the parking space can be connected to the State Grid's power lines. The most direct and effective method is to communicate with the property management, who will briefly assess factors such as space occupancy, installation plans, and power requirements. Understanding the types of charging stations: Generally, the type of charging station to install depends on the conditions of your home. Currently, home charging stations are mainly divided into wall-mounted and pole-mounted types. Wall-mounted chargers save space and are more affordable, but they can only be installed on walls where wiring is possible. Pole-mounted chargers, although they occupy relatively more space and are more expensive, have fewer limitations on installation locations. Therefore, users can choose based on their specific installation conditions.

What does a plug-in hybrid electric vehicle mean?

A plug-in hybrid electric vehicle, abbreviated as PHEV, is a new energy vehicle that falls between pure electric vehicles and fuel-powered vehicles. It has both the traditional car's engine, transmission, drivetrain, fuel system, and fuel tank, as well as the pure electric vehicle's battery, motor, and control circuit, with a relatively large battery capacity and a charging port. It combines the advantages of both pure electric vehicles (EV) and hybrid electric vehicles (HEV), enabling zero-emission driving in pure electric mode and extending the vehicle's range through hybrid mode. In daily use, it can function as a pure electric vehicle as long as the single usage does not exceed the battery's provided range (generally achieving over 50 kilometers is not a problem), thus achieving zero emissions and zero fuel consumption. Due to the high cost of batteries, it is difficult for such vehicles to enter households at a lower price in the short term. However, influenced by the domestic automotive development trends and government attention, corresponding subsidies have been increased. Based on the proportion of motor driving power to the total vehicle power (also known as the hybrid degree), hybrid electric vehicles can generally be divided into the following four types: micro hybrid, with a hybrid degree of less than 5%; mild hybrid, generally around 20%; moderate hybrid, with a hybrid degree of 30% to 40%; and full hybrid, with a hybrid degree of over 40%. Series plug-in hybrid electric vehicle: Also known as range-extended electric vehicles. The engine does not directly drive the car; instead, it first drives a generator to produce electricity, which then powers the motor to drive the car. The energy transfer chain is long, resulting in relatively low overall efficiency. Parallel plug-in hybrid electric vehicle: In this type, both the engine and the motor can drive the car. It offers multiple power transmission modes, good dynamic performance, simple structure, and wide application, making it the mainstream technical route. Series-parallel plug-in hybrid electric vehicle: Also known as power-split type. It generally requires two motors (one generator and one motor) and a planetary gear set for power splitting. This type has the most complex structure and control. Only a very few manufacturers have the capability to produce and manufacture this type of product, and there are certain patent barriers.

What are the requirements for upgrading to an A2 driver's license?

Upgrading to an A2 driver's license requires the following conditions: 1. Condition 1: Hold a "B1 medium-sized bus" or "B2 large truck" driving qualification for more than three years, with no full-point record in the last two scoring cycles before application. 2. Condition 2: Obtain an "A1 large bus" driving qualification for more than one year, with no full-point record in the last scoring cycle before application. 3. Condition 3: Drivers aged between 24 and 50 years old with a normally valid driver's license can apply to the local vehicle management office at their registered residence to add the permitted driving type.
