New energy vehicles and traditional cars differ in the following aspects: 1. Lifespan: The battery life of new energy vehicles is typically around 5 years, requiring replacement upon reaching its limit; traditional cars use engines that can last until mandatory scrapping with proper maintenance. 2. Environmental standards: New energy vehicles feature energy-saving and emission-reducing characteristics with less exhaust production; traditional cars have higher tailpipe emissions. 3. Noise levels: New energy vehicles operate quietly; traditional cars produce more noise. New energy vehicles consist of power batteries, car chassis, body, and vehicle electrical systems. As a crucial component of electric vehicles, the power battery system includes battery modules, battery management systems, thermal management systems, and electrical & mechanical systems.

There are quite a few differences between new energy vehicles and traditional cars. As an ordinary driver, I think the main differences lie in daily convenience and operating costs. Electric cars are quiet and smooth to drive, with quick acceleration, making them very comfortable for short commutes in the city, especially for picking up kids or daily commutes. However, charging is a big issue—finding charging stations isn’t as convenient as gas stations, and long trips require careful planning, often leading to range anxiety. In terms of costs, electric cars are cheaper to run, costing just a few dollars per 100 kilometers, and maintenance is simpler with no need for oil changes, saving a lot of money. However, the initial purchase price is higher. Gas cars refuel quickly and have longer ranges, making them more reliable for long trips, but fuel costs are higher and they pollute the air. When choosing a car for the family, it depends on your lifestyle—electric cars are better for city dwellers with lots of urban activities, while gas cars are more reliable for frequent highway driving.

I think the differences between cars are quite significant. From an environmental perspective, electric vehicles (EVs) have obvious advantages, with zero tailpipe emissions, reducing greenhouse gases and air pollution, contributing to climate change mitigation. Traditional gasoline or diesel vehicles produce large amounts of harmful gases during engine operation, which are a major source of urban smog. Although EVs have some carbon footprint during battery production, they are generally a greener mode of transportation, and governments encourage their adoption through subsidies. In the long run, EVs have high energy efficiency, with minimal energy loss during power conversion, supporting sustainable development for the planet. In terms of driving habits, EVs offer a quiet driving experience, avoiding noise pollution and making residential areas much quieter at night. However, charging infrastructure is still developing, with insufficient support in rural areas.

I'm particularly interested in mechanical structures. New energy vehicles use electric motors and battery systems to replace traditional internal combustion engines, which brings about key changes. The torque output of electric motors is direct and fast, with no delay in acceleration, unlike gasoline cars that require gear shifting via transmissions. The battery pack provides power, but the range is significantly affected by temperature, with reduced mileage in sub-zero conditions. Gasoline cars rely on burning fuel, featuring complex engines that require more maintenance, such as regular oil changes and spark plug replacements. Technologically, electric vehicles are more intelligent in control, featuring regenerative braking to recover energy, and their onboard systems receive frequent updates. The overall design is simpler, with fewer mechanical components, potentially leading to longer lifespans and lower failure rates, adapting to the era of technological innovation.
