Isn’t it dangerous to charge EV outdoors on a rainy day?

Electric vehicles have attracted much attention in recent years. The Tokyo Metropolitan Government has also set a goal of "increasing the proportion of Zero Emission bikes in new car sales in the city to 50% by 2030" and implementing various popularization measures.

However, the current penetration rate of electric vehicles is still not high, and there should be many people who are not sure about the performance of electric vehicles. What everyone is most worried about when driving an electric car is charging related matters.

Some electric car owners also asked on the Internet, "I often leave it plugged in to charge all night. Will there be battery leakage in rainy or snowy weather?"

Anyone who uses electricity will worry about leakage. When charging outdoors, is there a risk of electric shock if snow comes into contact with the charging pile?

No special countermeasures taken? Waterproofing methods for electric vehicle owners

First, let’s take a look at how people actually charge electric vehicles.

A car owner said: "I have been driving an electric car for about 6 years, and it can still be charged even in heavy rain or snow. I have also used fast charging and it has never had any problems. There is no need to take special precautions when it rains or snows. , it can be charged."

Although most people do not take special preventive measures, some people also take minimum preventive measures.

Another car owner said: "Because I live in the Tohoku region of Japan, I often charge when it snows, and I pay special attention to preventing water from entering the charging hole on the side of the car. Other than that, I don't do anything special. The precautions I have taken The countermeasure is just to hold an umbrella to plug in and out of the charging pile. If there is water dripping around the charging pile and freezes, it may not be possible to plug in and out smoothly."

Other than that, I didn't see any other particularly worrying comments. So is the risk of charging in bad weather really low? We asked the experts for their opinion.

Electric vehicles use high-voltage batteries and high-voltage electrical components with a maximum voltage of about 400V.

However, the high-voltage electrical parts it uses are all designed to be waterproof and dustproof. Of course, it is also designed to be rechargeable when it rains or snows, so the possibility of leakage is extremely low.

We also asked the Japan Automobile Manufacturers' Association, a general incorporated association composed of 14 car manufacturers, "Can electric vehicles be recharged in rainy days?" Their answers are as follows.

"The charger has anti-leakage treatment, so if the car and charger are maintained properly, there will be no leakage."

Just wipe the connection between the charging hole and the vehicle to reduce the risk of leakage. In the event of a real leakage, there will be sensors to detect the power outage. There is no problem in charging electric vehicles when it rains or snows.

Through the above article, we can fully understand that there is no need to worry about any charging risks.

The person in charge of the Automobile Industry Association also said: "If it were not a very early electric model, the driving distance would not be significantly shortened by turning on the air conditioner to remove fog."

The early electric vehicles more than 10 years ago used a design similar to a "hot kettle" heating wire to boil water, so they consumed a lot of electricity. When the Nissan Leaf was facelifted in 2012, it changed the air-conditioning to a "thermal mercury type" to improve its impact on cruising range.

JAF, which operates a road service business, also conducted a survey on effective cold protection measures for electric vehicles on December 21, 2021.

Reproduce the state where the vehicle cannot move in heavy snow, and set the air conditioner in the car to 25°C to observe how many hours the power can run.

The result of the investigation is that the remaining power level will be less than 10% after 9 and a half hours. In the same environment, if the air conditioner is not turned on and instead an electric blanket or seat heater is used, more than 50% of the battery is still available after 13 hours.

The external temperature during the experiment was -8.1°C, which is a very harsh environment, so the load on the air conditioner is also quite heavy. If it were not in an extremely special environment, it would be unlikely to be short of power.

Electric vehicles also continue to improve, striving to ensure that charging and driving are not affected by weather and temperature.
