As we all knowNew energy vehiclesThere are technical shortcomings in battery life and charging. However, the latest sudden typhoon rain unveiledNew energy vehiclesThe last piece"Fig leaf"。In this torrential rain in Fujian,New energy vehiclesThe damage suffered was more severe than other vehicles. Many car owners have expressed regret about buyingNew energy vehicles。What's going on?
The original text mentions that parked in the underground parking lotNew energy vehiclesIt's very miserable. This is becauseNew energy vehiclesofBatteryIt is generally installed near the chassis once it is floodedBatteryand the motor is easily damaged. Even if it is not started, once the water is entered,New energy vehiclesIt's basically scrapped. ReplaceBatteryThe ** is expensive, which is equivalent to buying a car at the same priceUsed carsNew energy vehiclesThe value retention rate is low, which makes the losses even greater.
And in contrast, fuelCarsThe losses are much smaller. Despite the fuelCarsIt can also be flooded, but as long as the engine is not ignited, the probability of engine damage is low, and there is wading insurance to make up for the loss. However,New energy vehiclesDue to its special construction, onceBatteryand water ingress into the motor, and even if it is not started, the vehicle is likely to be scrapped. New energyBatteryThe replacement of ** is expensive, a car of about 100,000New energy vehiclesIt may cost more than fifty or sixty thousand to replaceBattery, which is almost possible to buy a car with the same wear and tearUsed carsFinish.
In addition,New energy vehiclesThe electronic control system is more complex and requires major repairs after wading through water. In contrast, conventional fuelCarsThe electronic control system is relatively simple, so maintenance costs are reduced. On the issue of wading in the water,New energy vehiclesThere are even greater challenges. For some hardcoresOff-roadmodels, such as Land Patrol, Tu Le,Land Rover Old Defenderetc., their wading opportunities are very large, but they are still thereOff-roadIt is widely used in enthusiast circles.
SoNew energy vehiclesIn the rainy season, it is difficult to have a chance to rescue a flood in the middle of the rainy season. Power batteryAsNew energyThe core components of the car, usually locatedCarsUnder the chassis, manufacturers will take into account its waterproof performance when designing, but currently on the marketNew energyThe highest water resistance level of the car is only 4 meters of water for 30 minutes. In reality, once the vehicle is flooded, it is likely to be soaked in water all night. At this time,Power batterywill trigger a protection mechanism that automatically cuts off the circuit, and that meansPower batteryIt has been impossible to repair, replaceBatteryThe cost is too high, and the vehicle can only be scrapped.
So how to prevent itNew energyWhat about the car soaking in water during the rainy season?First of all, when passing through the wading section, you should always pay attention to the water depth and water potential, and pass through the wading area slowly and evenly. When the water depth is more than half that of an electric car tireElectric vehiclesIt's not a good fit to move on. If there is water immersion, do not start the vehicle, and it is best to let the manufacturer's professionals check and deal with it to avoid dangerous situations such as short circuits.
In addition, caution is also required when charging in rainy weather. In thunderstorms, try to avoid charging in an open place to avoid the human body andCharging pilescontact, becauseCharging pilesThe shell is usually metal, and it is prone to lightning during thunderstorms, which poses a certain safety risk. At the same time, remember not to wipe directly with your hands when there is rain splashing in the charging port or charging gun port, and you can choose a paper towel or rag to clean up the stagnant water.
Finally, for the purchaseUsed carsof consumers, be sure to check the vehicle's historical maintenance records, especially whether it has been soaked in water. Vehicles soaked in water are prone to safety hazards such as short circuits and spontaneous combustion of electronic systems, so they must be chosen carefully.
In short,New energy vehiclesSoaking during the rainy season does happen, and when it does, the damage to the vehicle is often huge and the repair cost is high. Therefore, in the purchase and useNew energy vehicles, you need to fully understand its waterproof performance and repair costs, and take corresponding precautions to protect the safety and assets of car owners.
