What is a car BCM?

Car BCM stands for Body Control Module, whose main function is to achieve discrete control functions and manage various electrical appliances, primarily controlling automotive body electrical components such as lights, wipers, door locks, power windows, and sunroofs. The functions of the Body Control Module include: power window and door control, central door locking control, remote anti-theft, lighting system control, heated power mirror control, instrument panel backlight adjustment, and power distribution. The Body Control Module coordinates different functions within the vehicle through signals, managing numerous vehicle functions including door locks, alarm sound control, interior and exterior lighting, safety features, wipers, turn indicators, and power management.

How many kilowatt-hours does a new energy vehicle consume in one hour of charging?

Charging for one hour consumes 0.22 kilowatt-hours. Generally, a 48V20A battery requires 1.5 kilowatt-hours to fully charge, while a 72V20A battery requires approximately 2.3 kilowatt-hours. Charging time: Generally, the larger the battery capacity, the longer the charging time. For example: A 12V48AH battery indicates a voltage of 12V and a capacity of 48AH. Using an external charger with a 4.8A current, it takes 14 hours to fully charge. Charging method: While the car is running, the battery is replenished by the generator. However, when the battery is severely depleted, it needs timely recharging. The car's own charging capacity is insufficient in such cases, and a portable charger must be used. Charging a car's starting battery requires 20 hours.

Should Cars Be Equipped with Mud Flaps?

Whether a car needs mud flaps depends on the owner's driving conditions. If the owner frequently drives on muddy or poor road conditions, then installing mud flaps is highly recommended. However, if the owner primarily uses the car for urban commuting, there is no need to install mud flaps. Every car is designed with its own aerodynamics, which effectively reduces wind resistance during driving and also aids in heat dissipation. Adding mud flaps may disrupt the intended aerodynamic performance of the vehicle.

What does the auto setting for car lights mean?

Auto setting for car lights refers to automatic headlights, which will turn on or off when the light intensity is greater or less than a certain value. The principle of automatic headlights is that photosensitive resistors and electronic component sensors send electronic signals to the ECU to inform it whether to turn on or off the headlights, or to switch between high and low beams. Different car light usage scenarios: 1. Daytime running lights, also known as position lights, are turned on during rain or when it is dim; 2. Low beams are used on roads with street lighting; 3. High beams are used on roads without street lighting; 4. Turn signals should be activated in advance when the vehicle needs to make a turn.

Is reverse gear R?

Reverse gear is R, both in manual transmissions and automatic transmissions, there is an R gear, which stands for reverse gear. Generally, automatic transmissions have four gears: P, R, N, and D, representing Park, Reverse, Neutral, and Drive respectively. Both P and N gears can be used when parking, but they are different. The P gear has a locking mechanism inside. When the P gear is engaged, the locking mechanism can lock the transmission gears, which indirectly locks the wheels. In this case, even without pulling the handbrake, the car will not roll. The N gear does not have a locking mechanism. If the N gear is engaged without pulling the handbrake, the car may roll.

Why does the reversing camera display no signal?

The reasons why the reversing camera displays no signal: 1. The data cable connected to the reversing camera is loose or has poor contact; 2. The reversing camera is damaged; 3. The gear position sensor is faulty. The reversing camera is also known as a parking assist system, or reversing visual system, or vehicle monitoring system. This system makes the situation behind the car more intuitive when reversing, and it is one of the very practical configurations for reversing safety. Before reversing, first check the situation behind the car, estimate the reversing route, and make sure that during the reversing process, try not to press the accelerator and control the speed not too fast. During the reversing process, do not always look behind the car. Under the premise of confirming the safety behind the car, it is necessary to observe the left and right rearview mirrors from time to time, pay attention to the distance between obstacles and the car body, and accordingly use the steering wheel to correct the position of the car body when reversing.
