Will the Body of an Electric Vehicle Leak Electricity While Charging?
2 Answers
Answer: Of course, it can leak electricity, especially in rain. Structurally, after the charging plug is inserted into the charging port, the plug's outer shell covers the connection part. Due to the installation, the charging port and plug are exposed, so theoretically, rainwater can flow inside. Additionally, charging stations provide a leakage protection mechanism. If the rain is particularly heavy and leakage is detected during the communication between the charging station and the vehicle, the charging current will automatically be cut off. Reasons for rapid car battery discharge: Reason 1: Prolonged battery use can make the car difficult to start. Typically, battery performance degrades significantly after three or four years. Although it may still start, the active material inside the battery deteriorates, and the connection between the positive and negative plates creates a circuit that drains the battery. Reason 2: The main issue could be insufficient power generation from the vehicle's alternator, indicating a potential problem with the alternator. If there are many electrical devices in use, the battery may become undercharged. Long-term undercharging can significantly reduce the battery's storage capacity, leading to difficulty starting the car the next day. Reason 3: There might be electrical devices continuously operating, such as trunk lighting or other devices not controlled by the ignition switch, consuming power. Reason 4: Occasional failure to start, after checking the alternator and the vehicle's static current without finding issues, suggests inspecting the starter relay for any sticking phenomena.
I was initially concerned about whether electric vehicle charging might cause electric leakage, given that the car body is made of metal. However, based on my experience of driving an electric car for over three years and frequently charging it in garages or at public stations, I've never encountered any electrification of the car body. This is because modern electric vehicles are designed with great attention to detail, featuring strict insulation materials and grounding systems that essentially confine the current to internal circuits. Manufacturers also conduct various waterproof and leakage-proof tests to ensure safety under extreme conditions. It's advisable to use original charging accessories and avoid operating in wet or rainy areas. If you're still worried, simply check the charging cable for any damage after each use, but otherwise, don't overthink it. In short, with improved safety standards, the risk of electric leakage is minimal, so just enjoy the convenience of electric mobility.
