Due to the reference of carbon fiber, the weight of the body can be reduced by more than 50%. Taking the weight loss of 100kg of the typical A-class model as an example, the weight of the whole vehicle is very obvious. It can be explained from the following aspects: 1 for 1 For a passenger car with a driving distance of 300km and a power consumption of 45kW·h, the same driving range can be reduced by 3.6kW·h by the industry expert “100kg per weight reduction and an increase of 8% driving range”. The battery saving cost is about 0.6 million yuan; 2, with a life cycle of 400,000 kilometers and an average electricity cost of 0.9 yuan/kW·h, the electricity cost can be saved in the life cycle of the vehicle by 400,000/100×1.2×0.9=0.32 million yuan. 100km saving 1.2kW·h electricity calculation); 3 Because of the application of carbon fiber materials, taking the production scale of 50,000 vehicles as an example, the saved investment in technology and equipment is converted into the economic equivalent of electric vehicles, in each vehicle. The amortization will save about 2,000 yuan; 4 because the process is streamlined, the personnel cost can be saved at least 1,000 yuan / Taiwan.
In total, the average cost per vehicle is 0.6+0.432+0.2+0.1=1.33 million, but these costs are not enough to offset the increase in the cost of the material itself due to the introduction of carbon fiber. It can be seen that the application of carbon fiber body still has a big problem. If you want to promote lightweight body, you can only start from reducing the investment in technology and equipment.

If you want to promote lightweight body, you can only start from reducing the investment in technology and equipment.
If the automobile realizes mass production of carbon fiber body, the cost of the carbon fiber material itself will also drop drastically, and the whole industry effect will be quite large, and the economic benefits will become more and more obvious. These are only analyzed from the perspective of carbon fiber. If we consider the factor of reducing the weight of the aluminum alloy body by 50kg, the economic effect is self-evident.
