With the rapid development of my country’s new energy automobile industry, the quality of new energy vehicles is greatly improved, but the problems such as the use of steam and charging difficulties are still constantly being ill. Since 2020, there has been “high energy efficiency”, “replenishing process safety”, the power-saving model has ushered in the new wind, the government side continues to introduce new policy guidance and improve the construction of the power exchange system, the enterprise side began to lay the ecology, common Explore the new model of new energy vehicles to make up the operation. This article is focused on exploring the development history of power saving mode and the results of staged development.

1 Better Place “Create a Qianhe”

Change station + battery rental + Parked national car. Better Place is the first operation company in the world, founded in 2007, headquartered in California, USA. The company’s combined Renault proposes a power-on solution for use the “electric electric separation + mileage bill” mode, that is, the user purchases the fluence ZE for electrici from Renault, but the battery is held by Better Place, providing battery rental, Charging and replacing battery services, and charges the customer with a monthly basis based on the driving mileage.

Better Place Substation

Zengli lassed Chinese players into the extension area. In 2010, Better Place and Chery jointly developed the production of electric vehicle models, and studied leading electric vehicles charging network solutions. In 2011, Better Place signed a strategic cooperation agreement with the Southern Power Grid and set up a power exchange experience center in Guangzhou.

$ 850 million in financing, $ 2.25 billion valuation. In the second half of 2007, Better Place got A round of $ 111 million financing, and then experienced a total of $ 850 million in general electrical and Morgan Stanley, with a valuation of $ 22.5 billion.

6 years of operation time, 4 countries carry out business. In 2007, the application for bankruptcy in 2013, Better Place expanded its business to 4 countries for 6 years. In December 2008, Better Place opened its first power-on station in Tel Aviv, Israel, and then opened in Japan, Danish, Australia, in December 2011, which focuses on Japan, Denmark, Australia. Layout country.

High cost & sales, ultimately to bankruptcy. Better Place Substation Expected Construction cost is 500,000 US dollars. The actual construction cost is as high as 2 million US dollars. In addition, it is preferentially set up 100,000 FLUENCE ZE electric vehicles to Renault, but the final sales is only 1% of the plan, and the construction operation cost is seriously exceeded. The sales of electric vehicles are far from the expected double factors, and the Better Place application is issued in May 2013.

2 Tesla “Strategy Abandon”

Strategically focus on fast charge. In 2013, Tesla launched a fast-conducting technology, and the shift time was shortened to 93 seconds, but due to high exchange costs, the shaped battery could not be shared, the power-on power is low, the operation efficiency is low, and it is difficult to integrate car enterprise resources. The problem of forming a general standard will quickly turn the development focus to superchard technology, strategically abandon the power transmission technology route and operation mode.

3 China’s exchanged “carry forward”

Different period replenishment technology routes have different weights, and at this stage, the electricity is overweight. In the early days: high exchange efficiency, enhance consumers to receive the acceptance of new energy vehicles, the national network lead, and the demonstration is mainly. Mid-term: Due to the high exchange cost, heavy asset operations, change in electric tricycles, and compatible models, the replenishment technologies gradually turn to charging, but some enterprises adhere to the power transmission. Try: Affected by new energy subsidies, private users can reduce the cost of purchase, taxi and other operational users can improve operational efficiency and reduce waiting time, gradually be recognized by consumers and market.

At the stage, the new policy driver shifting mode development. In 2019, the government introduced the development of new policies and regular electric exchange industries. The three ministries and other three ministries such as the National Development and Reform Commission in June 2019 jointly issued the key consumer goods update and upgraded and smooth resources recycling implementation plan (2019-2020) “, and put forward the development of enterprises. Bringing electrical combination, battery configuration flexible new energy automotive products; in April 2020, the four ministries issued a “Notice on Perfecting New Energy Automobile Promotion Application and Financial Subsidy Policy” In November, the State Council issued the “New Energy Automotive Industry Development Plan (2021-12035)”, which proposed to vigorously promote the construction of the electric network, and encourage the application of the power transmission mode. In addition, local governments have also proposed the operation incentive plan for power saving stations, stimulating the maintenance of the power-on infrastructure.

Charging and power-exchange complementary, power-saving market prospects. At the same time, electric vehicles with the electricity function are attached to the taxi, webmark, urban ship, municipal vehicles with high frequency, fast replenishment, and municipal vehicles.

According to the Department of Entertainment Chain, Beijing Taxi is equivalent to 0.35 yuan / kilometers in power transmission mode. The entire shift process is 3 minutes, and the charging mode is equally 0.25 yuan / km. The charging time takes about 1 hour. Beiqi taxi queuing

The number of national shipments has exceeded 600, and the Olympics, Jixiang and Bo Bot are the main force of the power-saving infrastructure construction. Operating enterprises in public domains have mainly protected from Austrian new energy, Hangzhou Bobi Technology (for taxi, etc.), and private sector exchange station operators mainly have a military car (facing the user). According to the data of China Charging Alliance, as of June 2021, there were 613 shots of the electricity exchange station, including 307 new energy sources, 192 Janshan, 164 Hangzhou Bertan Technology.

Take the new energy source as an example, as of March 27, 202, it is shipped more than 300 yuan, covering 20 cities across the country, accumulating 9 million shifting, equivalent to the average transfer station to complete more than 30,000 times Service, the shift capacity exceeds 220 million degrees, with a mileage of more than 1.3 billion kilometers. Plan 2025 years ago, the national layout is 100 cities, and operates 5,000 power plants, providing power-on services for 2,000 new energy vehicles.

More players in the field of change. The whole vehicle has accelerated the layout of the power transmission technology and accelerates the replacement of tram type iteration. Geely began to R & D technology, commercialization, commercialization in 2020, in February 2021, Geely’s first 10 smart shifting station in Chongqing Expressway Jingguan Service Area is synchronized at Jingguan, Pear Mountain, Wai Dragon, Wei Zi, Da Road 5 Input operations in the service area. Since June 2020, SAIC promotes the change version of model certification, Roewe EI5, Roewe R brand ER6 and other models into the recommended directory, and the new R standards in the future supports the charge.
