What does SOC mean in cars?

SOC is the abbreviation for state-of-charge, which refers to the charging status of a car battery, also known as remaining capacity, indicating the battery's ability to continue functioning. Below is a detailed explanation of SOC: 1. SOC is generally the ratio of charged capacity to rated capacity, expressed as a percentage. A battery typically has a rated capacity, and after charging for a certain period at a specific rate, you obtain the charged capacity. The ratio of this capacity to the rated capacity is the SOC. Its value ranges from 0 to 1, where SOC=0 indicates the battery is fully discharged, and SOC=1 means the battery is fully charged. 2. The battery SOC cannot be measured directly but can only be estimated through parameters such as battery terminal voltage, charge/discharge current, and internal resistance. These parameters are also affected by various uncertain factors such as battery aging, changes in ambient temperature, and the vehicle's driving conditions. Therefore, accurate SOC estimation has become a challenge to be solved in the development of electric vehicles.

Which country is Toyota from?

Toyota is a Japanese automobile manufacturer. Some of Toyota's models are produced in Japan, while others are domestically manufactured. The Toyota models that are domestically produced include the Avalon, Camry, Corolla, Highlander, Prado, Reiz, and Izoa. Toyota Motor Corporation (abbreviated as Toyota) is an automobile manufacturing company founded by Kiichiro Toyoda in September 1933 and officially established on August 28, 1937. In 1940, Toyota produced approximately 15,000 vehicles, 98% of which were passenger-cargo vehicles. That year, it launched a relatively compact new sedan equipped with a 4-cylinder 2.2-liter 48-horsepower engine, which in appearance was closer to the Swedish Volvo PV60. In 1973, with the outbreak of the Fourth Middle East War, the world economy encountered the first oil crisis. Under these circumstances, Toyota set its new starting point on the finiteness of resources and vigorously carried out campaigns to save resources, conserve energy, and reduce costs.

What is the working principle of an air brake system?

The working principle of an air brake system involves an air compressor driven by the engine, which compresses air and delivers it through a one-way valve into a wet reservoir. Inside the wet reservoir, the compressed air is cooled and undergoes oil-water separation. The air is then divided into two circuits: one circuit passes through the air reservoir and the middle chamber of a dual-chamber brake valve to reach the rear brake chamber, while the other circuit passes through the air reservoir and the lower chamber of the dual-chamber brake valve to reach the front brake chamber. Below is a detailed explanation: 1. When not braking. Both solenoid valves are not energized; the intake solenoid valve remains normally closed, and the exhaust solenoid valve remains normally open. Both diaphragm valves are closed under the action of their springs, ready to engage in braking at any time. 2. When braking. Neither solenoid valve is energized. Compressed air from the brake valve enters the right side of the diaphragm-type intake valve. Since the intake solenoid valve is closed, the passage between the compressed air and the control chamber on the left side of the intake diaphragm is cut off. At this time, the control chamber is vented to the atmosphere, and under the pressure difference, the diaphragm-type intake valve opens, allowing compressed air to enter the pipeline leading to the brake chamber. Additionally, since the exhaust solenoid valve is also not energized and remains open, compressed air enters the control chamber on the right side of the diaphragm-type exhaust valve. Under the combined action of its spring force and air pressure, the diaphragm-type exhaust valve remains reliably closed, ensuring that compressed air flows unimpeded into the brake chamber, producing a follow-up braking effect.

How to Accurately Determine the Position of Left and Right Wheels?

Judging the left wheel position: When the line of sight aligns the protruding node of the left wiper with an object on the ground, the left wheel will run over that object while moving. Judging the right wheel position: When the line of sight intersects the right wiper with the target, the tire will run over the target. Below is a related introduction on methods to judge the distance between vehicles: 1. When the edge line of your car's front aligns completely with the lower edge of the rear wheel of the car in front, the distance between the two cars is approximately 3.4 meters. 2. When the edge line of the car's front aligns with the lower edge of the front car's bumper, this is suitable for a distance of about 2.4 meters between the two cars. In congested urban areas, this distance is relatively safe. 3. When the edge line of the car's front aligns with the upper edge of the front car's bumper, the distance between the two cars is approximately 1 meter.

What does the circle A in a car mean?

Car circle A represents the engine start-stop technology, and that A button is called the automatic parking system. Here are the specific explanations: 1. After turning on this switch, when your vehicle comes to a complete stop during driving, even if you release the brake pedal, the vehicle will not continue moving. It will only resume driving when you press the accelerator, at which point the system automatically deactivates. If you want to turn it off, you must do so manually. 2. Engine start-stop technology automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. 3. The working principle of the start-stop system is that when the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates there is enough energy for the next start. When these three conditions are met, the engine automatically stops.

How to Remove the Front Windshield Film?

Use a knife to slightly pry up one corner of the film, then apply some force to peel the sticker off. During the peeling process, it's best to maintain a small angle between the peeled film and the car glass, and peel slowly and evenly. This will leave less adhesive residue.
