Is the charging noise of new energy vehicles very loud?
2 Answers
New energy vehicles do produce some noise during charging. Below is relevant information about new energy vehicles: 1. Advantages: Compared to traditional fuel vehicle technology, new energy vehicle technology can effectively reduce emissions, improve fuel efficiency, lower usage costs, and also has the advantages of smooth operation and low noise. However, new energy technology is still in the exploration and development stage, placing extremely high demands on current battery technology, precision mechanical and electronic control technology, and various supporting facilities. 2. Application Scope: New energy vehicle technology mainly reflects the upgraded national emission standards, including fuel cell vehicles, hybrid vehicles, hydrogen-powered vehicles, and solar-powered vehicles. These are primarily used to replace petroleum resources and control emission pollution.
As an enthusiast of new energy vehicles, I've observed that the noise level during charging depends on the charging method and equipment type. With home slow charging, the sound is generally very low, similar to the gentle hum of an air conditioner outdoor unit, mainly due to the internal cooling fan. Fast charging, such as DC charging at service stations with power exceeding 100kW, results in faster fan speeds and louder noises, comparable to a handheld electric drill but lasting for a shorter duration, typically around 50 decibels. This is not a design flaw but a necessity for the battery management system's cooling requirements; different vehicle models have varying optimizations, with newer Tesla models featuring quieter fans. Temperature also plays a significant role: noise is louder in summer due to higher cooling demands, while in winter, the sound is much softer. In daily life, I usually charge my car in the garage at night, where the noise is minimal and doesn't affect sleep or rest. If noise is a concern, opting for slow charging mode or upgrading to a soundproof charging station are viable solutions. Overall, this is not a major issue and is much gentler than the idle noise of fuel-powered vehicles.
