CR1220 battery

Who will win the final showdown between fast charging and fast charging in the power CR1220 battery pattern?

As the saying goes, there is no first in literature and no second in martial arts. Regarding the topic of which of the two modes, fast charging and battery swapping, has a better development prospect, the industry has different opinions, and the two camps of fast charging and battery swapping are always competing.

As the saying goes: The world's martial arts can only be broken by speed. In today's efficient society where "time is money", "speed" is the king. For a long time, slow charging speed and long time have always been the constraints on the development of new energy vehicles. To solve this problem, new energy vehicles have innovated two fast charging modes, fast charging and battery swapping, in the power supply solution.

As the saying goes, there is no first in literature and no second in martial arts. Regarding the topic of which of the two modes, fast charging and battery swapping, has a better development prospect, the industry has different opinions, and the two camps of fast charging and battery swapping are always competing.

The first confrontation, the battery swapping mode encounters

As a way of replenishing power for new energy vehicles, charging and battery swapping are two completely different technical routes, and fast charging is a charging mode. According to Einstein's theory of relativity, fast and slow are relative rather than absolute. Fast charging and slow charging are also relative concepts. Generally, fast charging is high-power DC charging, which can fully charge 80% of the battery capacity in half an hour. Slow charging refers to AC charging, and the charging process takes 6-8 hours. At present, domestic Weihong Power, Zhuhai Yinlong, and Miaosheng Power are the main representatives of the fast charging technology route, which can achieve fast charging in more than ten minutes.

Whether new energy vehicles adopt the charging mode or the battery replacement mode has been debated for a long time in the entire industry. However, in several head-on confrontations earlier, the charging mode to which fast charging belongs has prevailed, while the battery replacement mode has suffered.

The first company to launch the battery replacement mode was BetterPlace in Israel, which eventually declared bankruptcy due to high investment costs and slow development. In addition, Tesla has also vigorously promoted the battery replacement mode, but it ended up with expensive prices and poor service experience. The battery replacement mode once promoted by the State Grid of China also failed comprehensively.

At present, the charging mode is not only the mainstream method adopted by most domestic new energy vehicle companies, but also the perception of the charging method by most new energy vehicle owners. The reason why new energy vehicle companies insist on the "charging mode" is very clear: they can independently control core technologies such as batteries, and then take the initiative in the development of new energy vehicles, and also control the profits brought by battery technology. From the perspective of consumer use, the charging mode can avoid repeated disassembly and assembly of batteries, and if conditions permit, they can be charged at home, which is convenient and hassle-free.

The outcome is hard to determine again

Although the charging mode occupies the mainstream of the current new energy vehicle charging method, the battery swap mode still has a large number of supporters. Although the early battery swap pioneers encountered, now a group of car companies such as BAIC New Energy, Lifan, CHJ, and NIO have resolutely embarked on the road of battery swap, and the battery swap mode is likely to make a comeback.

In fact, the advantages of the battery swap mode are also very obvious. The battery swap mode can realize the separation of vehicle and battery value, and can resolve a series of pain points of pure electric vehicle users in the entire life cycle of purchase, use and exit at the consumer level. Moreover, the efficiency of the battery swap mode is very high. After the vehicle enters the battery swap station, the battery swap can be completed in about 3 minutes, which is no less than refueling a fuel vehicle.

At the same time, centralized and professional charging and discharging control is conducive to extending the battery life, and car owners no longer need to worry about the battery life and quality; it can also minimize the potential accidents caused by personal charging, and the safety is greatly improved. In addition, the battery swap mode can also use the low-peak electricity in the second half of the night for large-scale centralized charging, saving energy resources and reducing charging costs.

Wang Binggang, leader of the National 863 Energy-Saving and New Energy Vehicle Major Project Supervision and Consulting Expert Group, once said: "The battery swap mode has a relatively efficient operation cost-effectiveness advantage in some specific use environments, such as the field of electric taxis. Compared with the current mainstream charging mode, the battery swap mode has the advantages of smaller footprint, improved efficiency, and greatly reduced costs."

However, the disadvantages of the battery swap mode are still quite obvious. Its development obstacles mainly come from product standardization, business model, and inconsistent interests of vehicle manufacturers and battery swap operators. "One of the conditions for the sustainable operation of the battery swap mode is that the battery must be standardized. If the battery standards of different cars are different, the cost of the car company is too high. If each car company builds its own battery swap station, the economic account is difficult to calculate." Liu Yanlong, Secretary-General of the China Chemical and Physical Power Supply Industry Association, said.

Another obstacle to the battery swap model comes from the high initial cost investment. The construction of a battery swap station is similar to that of a gas station. Equipment, land, and operation all require a lot of costs, which is not enough with the strength of a few companies. Especially in the first- and second-tier cities where every inch of land is valuable, the output after investment is particularly important.

In short, the fast charging mode and the battery swap mode have their own advantages and disadvantages. Judging from the current technical level and commercial environment, it is difficult to determine which of the two modes will win in the future. Can the battery swap model make a comeback? Will the fast charging model continue to expand its market share? Is it a "life-and-death" fight or "peaceful coexistence"? These remain to be tested.
