The differences between fast charging and slow charging for electric vehicles are as follows: 1. Charging time: Fast charging can reach 80% in half an hour, while slow charging takes 6~8 hours to fully charge. 2. Impact on the battery: Fast charging may cause some damage to the battery, whereas slow charging is better for the battery's lifespan. 3. Charging mode: Fast charging directly connects to the vehicle's battery without passing through the onboard charger, while slow charging requires conversion via the charger. 4. Pros and cons: ① Advantages: Fast charging uses DC charging, which imposes higher requirements on the voltage resistance and protection of the power battery pack. Slow charging at a lower rate not only reduces heat and battery pressure but also benefits the long-term health of the battery. ② Disadvantages: The installation requirements and costs for fast charging equipment are very high. The higher current and voltage of fast charging can easily cause the active material of the battery to fall off and the battery to overheat, affecting its lifespan. Slow charging takes a long time and is only suitable for vehicles that operate during the day and rest at night.

Will points be deducted if rear passengers do not fasten their seat belts on the highway?

No points will be deducted for not wearing seat belts in the rear seats on the highway. Relevant information about seat belts is as follows: Emergency situations: When a car encounters an emergency and brakes suddenly, seat belts can restrain the driver and passengers in their seats to prevent them from being thrown forward, thereby protecting them from injuries caused by secondary impacts. Function: The function of a car seat belt is to instantly tighten when the vehicle collides or emergency braking is applied, pulling the slack in the belt to securely fasten the occupants to their seats and prevent secondary collisions. Once the tightening force of the seat belt exceeds a certain limit, the force-limiting device will appropriately loosen the belt to maintain stable chest pressure. Therefore, car seat belts serve to restrict movement and provide cushioning, absorbing impact energy and dissipating inertial forces to avoid or reduce the severity of injuries to drivers and passengers.

What is the Volkswagen air conditioning channel number?

Volkswagen air conditioning channel numbers are 0, 1, 2, 5, 6, 7, 12, 13. Meaning of each number: Number 0 indicates the AC switch is ON (air conditioning is activated), number 7 indicates the AC switch is OFF or there is a switch/signal malfunction. Number 1 represents low air conditioning pipeline pressure, while number 2 indicates high pipeline pressure. Number 5 means the ignition switch is ON, AC switch is ON, but engine speed is zero. Number 6 represents ECON mode with heater activated. Number 12 indicates rapid acceleration/engine starting state where air conditioning won't cool. Number 13 means the system detects low voltage and will shut down the air conditioning. Function of automotive channel numbers: Automotive channel numbers allow technicians to input specified values during maintenance for quick basic settings, making fault diagnosis more convenient.

Why does an automatic transmission always start in 2nd gear?

Automatic transmission always starting in 2nd gear is caused by a faulty transmission separator. Here is an introduction about the transmission: Introduction: The transmission, also known as a gearbox, is an automotive component used to alter the speed and torque from the engine, and can fixedly or stepwise change the transmission ratio between the output and input shafts. Function: It can be categorized into stepped, continuously variable, and integrated transmissions, with functions such as enabling reverse driving, interrupting power transmission, and changing gear ratios. Principle: Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations; while automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations.
