What are the classifications of electric vehicle batteries?

Electric vehicle batteries are classified into storage batteries and fuel cells. Storage batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries. Fuel cells are used for fuel cell electric vehicles, including alkaline fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, solid oxide fuel cells, proton exchange membrane fuel cells, and direct methanol fuel cells. The performance parameters of electric vehicle batteries are: 1. Electromotive force: Also known as the standard voltage or theoretical voltage of the battery, it is the potential difference between the positive and negative poles when the battery is open-circuited; 2. Rated voltage: Refers to the recognized standard voltage of the electrochemical system when the battery is operating; 3. Open-circuit voltage: The battery voltage under no-load conditions.

Can the car start after water enters the exhaust pipe?

Water entering the exhaust pipe can prevent the car from starting. After the car has driven through water: If water enters the exhaust pipe and the engine stalls, do not attempt to restart it forcefully. Instead, immediately call for roadside assistance and wait for help. If the water intake in the exhaust pipe is not severe: You can inspect the electronic systems yourself and remove any accumulated water under the car body. Then, remove the spark plugs to drain some water from the engine before reinstalling them. This process allows the engine to start and prevents stalling. If the car has been severely submerged in water: Roadside assistance is required to tow the vehicle to a repair shop. If water has entered the exhaust pipe, a simple cleaning and drying process is necessary before the engine can function properly again.

How long after the car is turned off can the car cover be put on?

You can put on the car cover about 5 to 10 minutes after the car is turned off, which will not harm the car or the cover. The car cover, commonly known as car clothing, is an outer cover made of canvas or other flexible and wear-resistant materials according to the car's dimensions. It is a protective accessory for cars, consisting of the cover body, buckles, and spring hooks. Its functions include: 1. Protecting the car paint and window glass from dirt, dust, water, rain, and snow; 2. Resisting UV damage to the car paint, interior, and tires; 3. Providing insulation to prevent excessive heat inside the car in summer; 4. Preventing scratches on the car paint by pedestrians or children, thereby extending the lifespan of the car paint.

What Are the Causes of Car Water Pump Leakage?

Car water pump leakage is caused by: 1. The water seal seat ring assembly was not installed properly during the installation of the water pump; 2. The machine is old, and the internal components of the water seal are worn, corroded, and aged, leading to failure; 3. The harsh working environment of construction machinery causes uneven wear of the bakelite sealing gasket and the bushing end face; 4. The spring is soaked in water for a long time, leading to rust and reduced elasticity; 5. The condensation of water vapor in the cooling system forms ice, causing the water pump body to crack due to freezing. The maintenance methods for car water pumps are: 1. Regularly check the sealing components to prevent internal water ingress, which can cause motor short circuits and burnout; 2. Replace the lubricating oil at scheduled intervals; 3. Perform regular rust removal.

How much current is needed to start a car?

Starting a car requires 100 to 300 amps of current, and the larger the engine displacement, the greater the starting current. Starting current refers to the minimum current obtainable under specific conditions at -17.8°C and -28.9°C, which can relate the battery's starting capability to variables such as engine displacement, compression ratio, temperature, starting time, the technical condition of the engine and electrical system, and the lower operating voltage for starting and ignition. The working principle of starting current is as follows: at the moment the motor is energized, the rotor speed is 0, and the synchronous rotating magnetic field cuts the rotor windings at a high speed, inducing a high electromotive force in the rotor windings and generating a large current. This current counteracts the magnetic flux of the stator field, and to maintain the original magnetic flux compatible with the power supply voltage, the stator winding automatically increases its current, thereby increasing the stator current of the motor.
