How is the chassis of a new energy vehicle different from that of a conventional car?

　　What is the difference between the chassis of a new energy vehicle and a traditional vehicle? There are significant differences between the chassis of new energy vehicles and those of traditional internal combustion engine vehicles in terms of design concept, structural layout and materials used. In terms of the power transmission system, traditional internal combustion engine vehicles rely on a complex mechanical transmission system consisting of the engine, drive shafts, etc. to drive the wheels, whereas new energy vehicles, especially pure electric vehicles, are driven directly by electric motors.

　　As the power source of new energy vehicles is a battery pack rather than fuel, this directly affects the design of the chassis. The battery is usually placed at the bottom of the vehicle to lower the centre of gravity and improve driving stability. The small size and relatively fixed position of the fuel tank in a conventional vehicle has far less impact on the chassis design than the battery pack in a new energy vehicle.

　　In terms of lightweight design, new energy vehicles often use more lightweight but high-strength materials such as high-strength steel, aluminium alloys and even carbon fibre to manufacture the chassis structure in order to improve the range, thus reducing the weight of the body. Although traditional cars are also pursuing lightweight, the choice and application of materials may not be so aggressive because there is no urgent need like new energy vehicles.

　　With the development of intelligent driving technology, new energy vehicle chassis are also at the forefront of intelligent configuration. Modern new energy vehicles are equipped with various sensors and advanced driver assistance systems. Although traditional cars are gradually introducing similar intelligent technologies, the overall integration and sophistication may be slightly less advanced.

　　How is the chassis of a new energy vehicle different from that of a conventional car? Considering the energy recovery system, this is one of the major features that differentiate new energy vehicles from traditional ones. With the regenerative braking system, new energy vehicles are able to convert some of the kinetic energy into electrical energy for storage when slowing down or braking, further improving the efficiency of energy utilisation.

Why don’t all new energy vehicles use the same type of powertrain?

 　　Why don’t all new energy vehicles use the same type of powertrain? The core reason why new energy vehicles do not uniformly adopt a single powertrain is that there are significant differences between different technology routes in terms of performance, applicable scenarios and infrastructure requirements, and companies need to choose the optimal solution based on technical characteristics and market demand. 　　Pure electric vehicles use batteries as the only power source, with a simple structure and outstanding zero-emission advantages, but range and charging time are still bottlenecks. However, performance degradation in low-temperature environments and insufficient coverage of charging facilities still limit their application in long-distance travelling or inconvenient charging areas. 　　Plug-in hybrid vehicles combine a fuel engine with an electric motor to achieve pure electric driving for short distances through external charging, while relying on the fuel engin...

Where does the power for new energy vehicles come from?

 　　Where does the power for new energy vehicles come from? The power sources for new energy vehicles are diverse, primarily including electricity and hydrogen fuel. These energy forms are more environmentally friendly and sustainable compared to the petroleum used in traditional fuel-powered vehicles. 　　Electricity is the primary power source for new energy vehicles. Pure electric vehicles rely entirely on batteries and electric motors for propulsion, without an internal combustion engine. Batteries are charged at charging stations or using home chargers, and electric motors convert electrical energy into power to drive the vehicle. 　　Hydrogen fuel is another important power source for new energy vehicles. Fuel cell vehicles use hydrogen as fuel, combining hydrogen and oxygen through fuel cells to generate electricity. This process only produces water vapour and other harmless by-products. The batteries in fuel cell vehicles utilise this electricity to drive the vehic...
