It is harmful for electric vehicles to pass through deep water. In addition to the power system and battery system, there are many internal circuits in electric vehicles. If water enters, it may cause damage to electronic components or lead to rusting of parts due to inadequate sealing of the vehicle body, affecting the performance of the electric vehicle. The following is a related introduction to electric vehicles: 1. Power source: The power source provides electrical energy to the drive motor of the electric vehicle, and the motor converts the electrical energy from the power source into mechanical energy. Currently, the most widely used power source is lead-acid batteries. However, with the advancement of electric vehicle technology, lead-acid batteries are gradually being replaced by other types of batteries due to their low energy density, slow charging speed, and short lifespan. 2. Composition: It includes the electric drive and control system, mechanical systems such as drive force transmission, and working devices to complete specified tasks. 3. Core: The electric drive and control system is the core of an electric vehicle and also the biggest difference from internal combustion engine vehicles.

Driving an electric vehicle through deep water is really dangerous. With over a decade of driving experience, I can say that the battery under the chassis is the weak point of an EV. If the water depth exceeds half of the tire height, water pressure may allow water to seep into the battery system, causing internal short circuits or even fires and explosions—this is no small matter. While a gasoline car's engine might be repairable if flooded, battery damage can result in terrifyingly high repair costs or even total vehicle write-offs. I recommend being extra cautious when driving during heavy rain, avoiding waterlogged areas whenever possible. If you must cross a puddle, maintain a speed below 15 km/h and only choose shallow sections. Remember, safety comes first—avoiding any risk is the wise choice. If you're unsure, take a detour. In case your vehicle gets flooded, pull over immediately, do not move it, and contact a professional repair shop right away for inspection to prevent future hazards.

What are the reasons for the poor cooling effect of the Mazda6 air conditioning?

Here is a detailed introduction about the poor cooling effect of the Mazda6 air conditioning: 1. Lack of refrigerant: Refrigerant wear is mainly due to leakage. If the condenser leaks, it needs to be replaced. When the leakage is severe, you can see oil stains on the surface of the condenser through the grille, which usually indicates a condenser leakage. 2. Damaged air conditioning flap: Damage to the air conditioning flap motor is relatively rare, but it does happen. The flap motor is usually located in the lower middle part of the instrument panel and serves as the main switch for the air conditioning vents. Once the flap is damaged, even if the air conditioning can produce cold air, it can only escape through gaps. 3. Dirty condenser: The main purpose of cleaning the radiator and condenser is to dissipate heat. If spring catkins and willow catkins accumulate on the condenser, it can cause issues such as high engine temperature or poor air conditioning performance. When cleaning, make sure to blow them away first before using a water gun to clean, otherwise, it may have the opposite effect, leading not only to poor air conditioning but also increased fuel consumption. 4. Damaged air conditioning compressor, throttle valve, or expansion valve: If the low pressure is high and the high pressure is low, the compressor needs to be replaced. Faults in the expansion valve or throttle valve directly result in poor air conditioning performance. These checks are relatively complex and require professional repair shops. 5. Aging or loose belt: Generally, during maintenance, the 4S shop will remind you to replace the belt. If it is not replaced, slipping may occur during use, leading to belt breakage, belt noise, loss of power assistance, and poor air conditioning performance.

How many times does a private car need to be inspected annually after 15 years?

Private cars that are over 15 years old require two annual inspections. Vehicle annual inspections can accurately detect any issues with the vehicle, which can then be repaired based on the identified problems. The vehicle is only allowed on the road after passing the inspection. Vehicles that fail the annual inspection are not permitted on the road, and driving them is considered illegal.

What is the difference between SP and SN gasoline engine oils?

The differences between SN and SP engine oils are as follows: 1. Different viscosity levels: The difference between SN and SP engine oils lies in their thickness or viscosity (phosphorus content) at a certain temperature. SN engine oil has a relatively lower phosphorus content. 2. Different viscosity numbers: Comparing the viscosity of SN and SP oils, SP has a higher viscosity number, indicating that SP's oil film is stronger than SN's, providing better protective performance. Additionally, SP offers stable improvements over SN in terms of noise reduction, fuel consumption, and acceleration performance. SP represents the oil quality grade, where SG, SJ, SL, SM, and the subsequent SP are all grades of gasoline engine oils. SP is currently the highest grade of gasoline engine oil, and the higher the grade of the oil, the better its various technical indicators.

Where is the windshield washer button located?

The windshield washer button switch is generally located on the control stalk on the right side of the steering wheel. The design of the stalk may vary between different car models, but the principle of operating the washer fluid spray is basically the same. The windshield washer switch is the stalk on the right side of the steering wheel, which also serves as the wiper controller. Wiper Introduction: Wipers, also known as windshield wipers, are devices used to wipe away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. How to Use Wipers: On rainy days, when raindrops fall on the windshield, the view ahead quickly becomes obstructed, making vehicles, pedestrians, and scenery appear blurry. At this point, turning on the wipers will restore clear visibility ahead.
