The hottest solution to the charging pain point of

Breaking the charging pain point of new energy vehicles, the power exchange mode may become a new outlet in the industry

now "power exchange mode" has become a hot word in the field of new energy vehicles. Changing electricity means replacing the power battery for electric vehicles. Compared with charging mode, the biggest advantage of changing electricity mode is that it is more efficient and fast. In May this year, as an important part of the new infrastructure, the power exchange station was written into the government work report for the first time, and the power exchange mode also ushered in a new situation of development

since July, many car companies have made new moves in the power exchange market. Some joint service providers set up a power exchange alliance to explore the power exchange market for the first time; Others are ready to work with partners to vigorously build power stations. Why has the power exchange mode received unprecedented attention? Can it replace the charging mode and become the mainstream in the future

the power exchange mode solves the "pain point" of electric vehicle charging.

since last year, the power exchange mode of new energy vehicles has been "supported" by many departments such as the Ministry of industry and information technology, and the power exchange mode is ushering in a tuyere

according to media reports, at an electric vehicle replacement station on the North West Fourth Ring Road in Haidian District, Beijing, an endless stream of pure electric taxis came to replace the electricity, and the whole process of replacing the electricity was very simple. The average time of replacing the electricity for a car was about 3 minutes

it is understood that the power exchange station receives about 150 taxis on average every day, and the whole power exchange process is operated by electrification. Compared with charging, the power change mode is shorter and faster, and it can also save more time and cost for taxis

compared with charging, it is faster to change electricity, and it can also save more time for taxis to carry passengers. "You can change the battery at the power station about once a day. You can run about 230 kilometers each time. It's very convenient and the cost is lower than charging." A taxi driver said

"due to the decline of subsidies for new energy vehicles, compared with fuel vehicles, the price advantage of electric vehicles is no longer, and the power exchange mode can reduce the cost of vehicle enterprises." Industry insiders have said that with the continuous increase of the number of electric vehicles, advocating the development of power exchange mode at this time can effectively solve the problem of charging difficulty

the policy encourages the power exchange mode to usher in the development outlet

on July 27, BAIC Motor Corporation Limited and a project to study and explore new light-emitting materials for labels have already raised funds. China Electric Vehicle Service Co., Ltd. signed a framework agreement to deepen strategic cooperation. In the future, China electric vehicle Corporation and BAIC bjev will continue to carry out in-depth cooperation in the field of power exchange, and take the lead in piloting the separation of vehicle and power, striving to jointly build 100 power exchange stations by the end of June 2021, serving at least 10000 power exchange vehicles nationwide

Xu Heyi, the former chairman of BAIC group, once said that after years of efforts, BAIC group has formed a domestic leading technical system in vehicle technology, three electricity system, intelligent connection, etc., especially in the field of power exchange. BAIC group has been deeply engaged in power exchange for many years, and has invested nearly 20000 vehicles for rent. After cooperating with BAIC group, China electric vehicle Corporation will give full play to their professional advantages and launch the business model of operating naked car sales and battery leasing on a large scale for the first time in China

in addition, Weilai automobile, which explored the power exchange mode earlier in China, will establish a battery asset management company to operate the power exchange business. Chang'an new energy has also established a power exchange alliance with power enterprises, power exchange service providers, battery enterprises, etc., committed to promoting the power exchange mode

in May this year, as an important part of the new infrastructure, the power exchange station was written into the government work report for the first time, and the power exchange mode also ushered in a new situation of development. The Ministry of industry and information technology has clearly supported the development of power exchange mode. On July 23, Xin Guobin, Vice Minister of the Ministry of industry and information technology, revealed at the press conference of the state information office that the "new energy vehicle industry development plan (year)" has been submitted to the State Council, and the next step will be to speed up the release. He stressed that in the next step, we will work with relevant departments to vigorously promote the construction of charging and changing infrastructure, further improve relevant technical standards and management policies, and encourage enterprises to develop models of switching mode according to the use scenarios, which will be piloted in Beijing, Hainan and other places

lianqingfeng, deputy secretary of the Party committee and spokesman of BAIC new energy, believes that the fundamental reason why the power exchange mode can be recognized is that the power exchange mode can effectively solve the bottleneck problem of new energy development and promote the industry to mature. In solving the charging problem of new energy vehicles, China has reached a consensus that "slow charging is the main thing, supplemented by fast charging, and electricity change is encouraged". However, slow charging is faced with the problem of "difficult pile building", which cannot achieve large-scale comprehensive coverage, and has become a key bottleneck affecting the growth of new energy vehicle consumption. "According to research statistics, about 70% of Chinese car users do not have fixed parking spaces, and only 40% - 50% of new energy vehicle users can install exclusive charging piles." Lian Qingfeng said. Fast charging not only affects the service life of power batteries, but also increases the distribution load of urban electricity

in contrast, the energy replenishment process in the power change mode is faster than refueling, and there is no need for parking space support, which is more intensive and efficient. Through the separation of vehicle electricity value, consumers can lower the purchase threshold and solve the problem of low residual value of new energy vehicles. Through the unified management and centralized slow charging of batteries, it can effectively ensure the charging safety and battery life, and help cities cut peak and fill valleys, so as to absorb more renewable energy. In the future, big data operation will also become an important part of energy interconnection and smart city construction

BAIC bjev leads the industry in the power exchange mode

it is understood that BAIC bjev has been exploring and deploying the power exchange mode for 10 years. BAIC bjev has started the pre research of power exchange technology since about 2011, carried out the development and verification of power exchange products in, began to explore the demonstration operation of power exchange mode in, and realized commercial operation. Since 2018, it has entered the stage of large-scale operation and promotion. Up to now, the company has built and operated 187 power stations in 19 cities, with 18000 replacement trams in operation, 4.8 million times of replacement, and a total mileage of 690million kilometers. At present, these data are leading nationwide and even globally, and BAIC bjev is undoubtedly the "C" leader in the field of power exchange

in terms of technology, BAIC bjev has mastered many key technologies, such as vehicle positioning system, quick change connection system, chassis power change system, battery life cycle management technology, quick change battery box, power change network operation management, etc. In particular, the power battery evaluation with strong "identification ability" has made these product evaluation technologies. The integrated network platform of battery tracing, monitoring, evaluation and operation based on big data analysis can realize the rapid evaluation of retired power batteries through vehicle charging data and rapid detection data. The evaluation time is 0.5 hours and the evaluation accuracy is 90%. In addition, BAIC bjev's "safe and efficient power exchange technology for pure electric passenger vehicles" project also successfully won the 2019 "China automotive industry science and Technology Award"

in terms of products, BAIC bjev has successively launched ev160/eu220/eu260/eu300/eu5 quick change versions and other tram models. The maximum cumulative mileage of a single vehicle has exceeded 850000 kilometers, and the overall safety is much higher than that of rechargeable models. The next generation of products are being developed with new platforms, including the arcfox brand. Charging and changing tram models are considered simultaneously, and the driving range can cover kilometers, fully entering the to B and to C markets

at the same time, the power station has also been upgraded several times, and now the floor area has been reduced to 70m2, which may tear the sample or break point difference;, The power change time has been reduced from 3 minutes to 1.5 minutes, and the battery adaptation rate has been greatly improved

at present, BAIC bluevale also gives full play to the role of state-owned enterprises and industry leaders, and has in-depth cooperation with industrial chain partners such as Ningde times, SK, Mercedes Benz energy, Aodong, Guodian, Nanfang power, greenmei, haopeng, etc., to establish a "satellite blue ecological alliance" to promote the standardization process of the entire power exchange industry. It is understood that China has formulated and issued 26 national standards and 18 industrial standards in terms of terms and information related to power change mode, planning and design, construction acceptance, quick change battery box, battery system interface, power change station, operation service network, operation management, service management, safety and evaluation methods of changing trams. In the future, we will also work together to rebuild and create the value of power battery in the whole life cycle, link the four major fields of vehicle manufacturing, energy management, smart travel and smart city, and build a multidisciplinary and interdisciplinary ecosystem of IOT, intelligence and sharing

the arrival of the new infrastructure outlet makes the power exchange mode more snapshot into reality. The new energy vehicle industry is showing richer connotation and extension, and its development space will be beyond imagination
