Can New Energy Pure Electric Vehicles Be Charged on Rainy Days?
2 Answers
New energy pure electric vehicles can be charged on rainy days. During the construction of charging piles, waterproof materials are applied to the bottom of the charging facilities, enabling the lower part of the charging pile (approximately 20~30 cm) to withstand water immersion. The national standards for the waterproof performance of charging piles are very stringent. Before charging begins, both the vehicle side and the pile side undergo insulation testing. If the insulation test fails (due to rainwater or debris), charging cannot be initiated. Relevant information about automotive batteries is as follows: 1. Introduction: Automotive batteries, also known as storage batteries, are a type of battery that works by converting chemical energy into electrical energy. Typically, the term "battery" refers to lead-acid batteries, which are mainly composed of lead and its oxides, with sulfuric acid solution as the electrolyte. 2. Working Principle: The battery uses lead plates filled with sponge-like lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and 22~28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.
There's basically no problem charging a pure electric new energy vehicle on rainy days. The waterproof rating of current charging interfaces is generally IP67 or above, so they can even withstand being submerged in water for half an hour. The charging stations themselves are also designed to be waterproof, making it normal for them to operate in the rain. However, it's worth reminding that it's best not to plug or unplug the charging gun in heavy rain; you can do it under an umbrella or in a garage. Once, I was charging during a heavy downpour and noticed the surface of the charging station was completely wet, but the current remained stable, proving the sealing is indeed robust. Still, it's important to avoid areas with severe water accumulation, as there could be risks if the charging port gets flooded. Opting for charging stations with canopies is the most worry-free and safe choice.
