'Questioning' behind the power battery electric car with a battery life of 1,000 kilometers

Recently, many car companies, including GAC New Energy, SAIC's Zhiji Auto, and Weilai, have announced that they will launch electric vehicles with a battery life of 1,000 kilometers, which has triggered disputes and discussions on the maturity and feasibility of supporting battery technology in the industry. In the realization of 1,000 kilometers of battery life, different car companies and battery companies have given differentiated implementation paths. Some use graphene-based technology, some use 'silicon doped lithium' technology, and some use solid-state battery technology. Regardless of the technology, we must face up to the fact that mass production and loading of vehicles in a short period of time is not realistic, and from the perspective of industrial technology and market development, this move is to a large extent a commercial follow-up behavior, not reason. First, in the absence of revolutionary innovation in technology, higher cruising range means more batteries must be stacked in the car, and the body weight of the car is higher, which in turn leads to higher overall energy consumption and carbon emissions of the vehicle. This is not in line with the overall goal of carbon reduction. Second, the cruising range has increased too fast, and the safety of electric vehicles has reduced risks. In addition to the 'stack batteryThird, the cost is high. At this stage, the increase in cruising range is generally accompanied by an increase in cost, because the battery is the most expensive component of electric vehicles. The 1,000-kilometer battery life is unreasonable in terms of economy, and it will cause electric vehicles to be more expensive than fuel vehicles. The latest commercialization of solid-state batteries and graphene-based batteries has long faced the problem of high costs. From another point of view, the pursuit of battery life by car companies has actually exposed consumers' current problems in the convenience of charging. Industry analysis pointed out that to solve the pain points of battery life anxiety, it is not reasonable to simply pursue battery life, but a breakthrough should be found in the convenience of charging. Many people in the industry have pointed out that in order to solve the mileage anxiety of electric vehicle consumers, the convenience of charging is more important than the improvement of the range. The two parameters of the convenience of charging and the range must be properly coordinated, otherwise they will fall into blindness. On top of the 'lost' endurance.
