What do hybrid and 48V mild hybrid mean?

Mild hybrid 48V, as the name suggests, increases the original 12V voltage by four times, enabling it to easily power higher-wattage in-car electrical equipment. This allows high-power electrical devices such as the steering system, starter motor, and air conditioning to continue operating even when the engine is turned off. A hybrid vehicle, on the other hand, adds one or more drive motors to the internal combustion engine. These motors not only assist the engine in generating stronger power but can also independently drive the vehicle at low speeds or under steady-state conditions, especially in congested urban environments where hybrids demonstrate significant fuel-saving effects. The 48V mild hybrid system is an additional power component outside the internal combustion engine, primarily consisting of a BSG motor-generator, a 48V battery, and a DC-DC voltage converter. It is mainly used during startup or idle stops and can also support a large number of electrical devices. During startup or brief idling, the BSG motor-generator helps the engine avoid idle power consumption. During braking, the BSG acts as a generator to quickly suppress the engine's speed and recover this energy into the battery. For example, when stopping at a red light, the engine can be turned off while the battery powers the air conditioning compressor and cooling water pump to keep them running. For hybrid vehicles, the electric motor typically operates during startup. Generally, when the vehicle speed exceeds 40 or 60 km/h, the engine will intervene. This period is usually short but relatively energy-efficient. However, during stops at red lights or braking, energy is recovered, but the engine remains running and does not shut off. Compared to the 48V mild hybrid, this setup tends to consume more fuel.

What Causes the Tire Pressure Warning Light to Flash?

Tire pressure warning light flashing can be caused by the following reasons: Punctured tire: This situation usually results in very slow air leakage, making it difficult to immediately identify which tire is affected. In this case, you can use a tire pressure gauge to measure the pressure (front: 2.3, rear: 2.5). If the pressure is low, inflate the tire to the proper level and then observe the tire pressure warning light. If it lights up again after a few days, you may need to remove the tire for inspection. Overinflated tire: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. Therefore, if any tire exceeds 3.0bar, it may trigger the tire pressure monitoring light. Prolonged driving with low tire pressure: This usually occurs when a tire has significantly low pressure, and high-speed driving causes the tire temperature to rise, leading to increased tire pressure. In such cases, you should promptly stop to rest or replace the tire with a spare.

When is the maintenance time for the Audi Q5L?

Audi maintenance is generally performed once a year or every 10,000 kilometers. Car Maintenance: Car maintenance refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Audi Q5L Maintenance Items: Replace engine oil and oil filter, visually inspect the engine for leaks or damage, visually inspect all components related to exhaust emissions, check the exhaust system for leaks or damage, check the concentration of coolant/antifreeze, add coolant or adjust concentration if necessary, query the self-diagnosis system fault memory, check the thickness of brake friction linings, visually inspect the brake system for leaks or damage, check the brake fluid level based on the wear status of the brake friction linings, visually inspect the transmission, final drive, and constant velocity joint boots for leaks or damage, check the steering ball joint dust boots for leaks or damage, check the tread depth and wear pattern of all tires, check tire pressure and adjust if necessary, check the battery electrolyte level and add distilled water if needed, check the steering tie rod joint clearance, tightness, and dust boot condition, check the air reservoir and drain valve for cleanliness and clean if necessary, check and lubricate the function of door locks, safety locks, and child safety locks, check the function of lighting, turn signals, hazard warning lights, warning/indicator lights, and horn, check the function of windshield wipers/washers, headlight washers, washer nozzles, and the stopping position of the wipers.

Do Rear Wheels Need Dynamic Balancing?

Two reasons whether rear wheels need dynamic balancing: 1. Necessary: Involves wheel disassembly/reassembly (1) When replacing rims, tires, patching tires, installing TPMS modules, or changing valve stems of different materials, tire dynamic balance needs readjustment. (2) For asymmetric tread or unidirectional tread tires - both have fixed rolling directions and can only rotate one way. Installation must ensure correct orientation to prevent reduced wet traction. 2. Unnecessary: Only involves wheel assembly removal (1) When simply rotating tires front-to-rear, as this only involves wheel assembly repositioning.
