Condensation water around the evaporator is perfectly normal. Below is an introduction related to new energy vehicles: 1. Development History: From the birth of the first electric vehicle in 1834 to the prominence of new energy vehicles as the main attraction in international auto shows by 2011, new energy vehicles have traversed nearly 180 years of history. After nearly two centuries of fluctuating development, new energy vehicles have achieved unprecedented breakthroughs in variety, technology, and market share. As a segment of electric vehicles, hybrid vehicles, pure electric vehicles, and fuel cell vehicles dominate the development process of new energy vehicles and have received more attention than other types of vehicles. The century-long journey of new energy vehicles can be broadly divided into four stages: the birth of electric vehicles, the renewed focus on electric vehicles, the development of hybrid and other vehicle types, and the market-oriented development of pure electric vehicles. 2. Power Sources: From a global perspective on the development of new energy vehicles, their power sources mainly include lithium-ion batteries, nickel-metal hydride batteries, lead-acid batteries, and supercapacitors, with supercapacitors mostly appearing in the form of auxiliary power sources. The main reason is that these battery technologies are not yet fully mature or have obvious shortcomings, and there are considerable gaps compared to traditional vehicles in terms of cost, power, and range, which is also an important factor restricting the development of new energy vehicles.

I just encountered this situation last week - a puddle of water under the front of my car gave me quite a scare. After consulting with a 4S店 technician, I learned that it's completely normal for new energy vehicles to drip water after using air conditioning. The principle is the same as home air conditioners: during cooling, moisture in the air condenses into water droplets that flow out from beneath the evaporator. However, pay attention to the location: dripping from the middle or front of the undercarriage is fine, but if you see green or pink liquid leaking beneath the battery pack, you should stop immediately for inspection. As a tip, the lower the water temperature during cooling, the more water will drip - in summer you'll often notice the underside of the car getting quite wet.

As an owner who has driven three electric vehicles, I'm all too familiar with this issue. It's completely normal for new energy vehicles to drip water under the car when the air conditioning is on. The key is to observe the water trail location – don't panic if you see accumulated water below the front bumper, that's where the AC condensate drains. But pay attention to the color: clear water is fine, while colored liquids or oily substances definitely indicate a problem. My neighbor's EV once leaked light blue coolant, which turned out to be caused by loose pipe connections. My advice is to take a quick look at the discharged liquid after turning on the AC – this simple check can prevent major troubles.

From the principle of heat exchange, dripping is normal. When the electric vehicle's air conditioning is cooling, the hot air inside the car passes through the evaporator and cools down instantly, causing the water vapor in the air to condense into water droplets. I've measured that during hot weather, running the air conditioning for an hour can discharge two soda bottles' worth of condensate. Some plug-in hybrid vehicles with range extenders may also have dripping from the exhaust pipe, similar to fuel-powered vehicles. The key is to identify the dripping location: the air conditioning drain pipe is usually at the front of the chassis, while the battery pack is typically in the middle. If you see thick liquid leaking from the middle of the car or water with coolant color, it could be dangerous.
