What is the normal voltage after a car starts?

After a car starts, the normal voltage of the battery is 12V, but in reality, it is higher than 12V. The car battery is always in a floating charge state, with a floating charge voltage of around 14-14.5V. Below is a detailed introduction about the battery: Overview: The battery is a type of cell, also known as a storage battery. The working principle of the battery is to convert chemical energy into electrical energy. The usual battery refers to a lead-acid battery, which is mainly composed of lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. Others: The plates of an ordinary battery are made of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low cost. The disadvantages are low specific energy (i.e., the amount of electrical energy stored per kilogram of the battery), short service life, and frequent daily maintenance.

Can Car Locks and Keys Be Replaced?

Car locks and keys can be replaced. There are mainly two types of car keys: mechanical keys and remote keys, both of which can be duplicated and replaced. Currently, car keys are typically remote keys. Below is a detailed introduction about car remote keys: Overview: Car remote keys utilize the wireless remote control function of the central locking system, allowing doors to be opened and locked from a distance without inserting the key into the lock. The advantage is the ability to remotely lock and unlock the car anytime and anywhere. Additionally, they can sense the vehicle's location. Components and Classification: The car remote key system mainly consists of two parts: the transmitter and the receiver. The transmitter includes components such as the transmission switch, transmission antenna (keypad), and integrated circuits. Based on their usage methods, they can be classified into three types: active working mode, passive working mode, and coil induction mode.

What Do the Dashboard Warning Lights Mean?

Dashboard warning lights represent various vehicle conditions: the engine fault warning light indicates engine malfunction; the battery indicator signals either depleted battery charge or alternator failure; the oil pressure warning light shows low oil pressure; the coolant temperature warning light indicates overheating; the ABS fault warning light denotes anti-lock braking system malfunction; the antifreeze warning light means insufficient coolant level; the door ajar warning light shows improperly closed doors; the brake fluid warning light indicates low brake fluid level; and the airbag fault warning light signifies issues with the safety airbag system. Vehicle indicator lights serve three primary functions: 1. Oil pressure indicator: Displays engine oil pressure status. It illuminates during vehicle self-check when turning the ignition key and extinguishes after engine start. 2. Coolant temperature indicator: Shows engine coolant temperature. It only lights up for seconds during self-check and remains off during normal operation. 3. ABS indicator: If the ABS light doesn't flash during engine start or remains lit afterward, it indicates ABS system malfunction.

What are the functions of the buttons on a car?

The following are the introductions to the functions of car buttons: 1. Light buttons: Vehicle lights need to be turned on differently in various situations, mainly including low/high beams, fog lights, position lights, hazard warning flashers, turn signals, etc.; 2. Air conditioning buttons: In summer and winter, when temperatures are extreme, drivers and passengers often turn on the air conditioning for comfort, but incorrect operation of the air conditioning buttons can affect its effectiveness; 3. Wiper buttons: Wipers are commonly used during rainy days and also when the windshield is dirty. However, improper use during rainy days can impair visibility and easily lead to traffic accidents; 4. Front/rear hood buttons: Generally, the front hood is opened less frequently, only during maintenance and repairs, while the trunk is used more often. These two buttons are usually located on the left side of the driver's position.

Does a Car Chassis Need Cleaning?

Under normal circumstances, a car chassis does not require cleaning. The car chassis is one of the components of a vehicle. Below is a detailed introduction about the car chassis: Overview: The car chassis consists of four main parts: the transmission system, the running gear system, the steering system, and the braking system. The function of the chassis is to support and install the car engine and its various components and assemblies, forming the overall shape of the car. It also receives power from the engine to enable the car to move and ensure normal driving. Additional Information: The transmission system of a car chassis is generally composed of the clutch, gearbox, universal transmission device, main reducer, differential, and half-shaft. The transmission system can be classified into mechanical transmission, hydraulic transmission, hydrostatic transmission, and electric transmission based on different energy transfer methods.

Can the Start-Stop Function of the Excelle Be Permanently Disabled?

The start-stop function of the Excelle cannot be permanently disabled. Pros and cons of the automatic start-stop system: 1. Pros - Fuel saving: Whether waiting at a red light or stuck in traffic, the engine automatic start-stop technology can automatically shut off the engine when the vehicle is stationary, achieving the goal of fuel economy. 2. Cons - Increased vehicle costs: Cars equipped with the automatic start-stop system are more expensive than those without. Additionally, due to the frequent starting and stopping of the engine, there is a higher demand for oil quality. Impact of engine start-stop on the vehicle: 1. The engine and start-stop system configured for start-stop functionality can endure hundreds of thousands of cycles, essentially matching the lifespan of the vehicle. 2. The start-stop function only stops the engine from working, but the oil system does not stop. This means that even though the engine is not running, oil will still circulate inside the engine, ensuring better lubrication when the car starts again, thereby protecting the engine.
