Electric car battery rental test

Recently, news came from Xiamen that it will test the battery rental business of electric vehicles, which not only reduces the cost of purchasing electric vehicles, but also significantly shortens the charging time. In this regard, the industry believes that this move is a good attempt, but the high investment and the current domestic electric car battery standards are not unified will reduce the effect of this move.

The battery industry development "blocker"

According to data from the China Association of Automobile Manufacturers, only 8,368 new energy vehicles were produced in China in 2011, and 8,159 new energy vehicles were sold. The development of electric vehicles is not "ideal."

"One is that the price is too expensive, and secondly, it is still inconvenient." In response, the deputy secretary-general of the Federation of Machinery Industry of Hubei Province, Gu Changhua analyzed that an ordinary electric vehicle has a battery cost of 60,000 yuan - 70,000 yuan. It accounts for half of its cost. In addition, there are fewer charging facilities and the lower mileage reduces the user experience.

It is reported that there are two types of fast charging and slow charging for electric vehicles. Slow charging takes 2 hours and fast charging only takes 5 minutes. However, Mr. Wang, an auto maker, told reporters that if the model of fast charging is used for a long period of time, the battery life may be only one or two years, and the cost of purchasing the battery again is too expensive. If you use slow charging, “Who wants to wait for two hours?” Prior to this, some media reported that the usage rate of charging piles in some places was less than 30%.

Battery leasing standards and investment are key to the above issues. Xiamen recently introduced new measures. The replacement station provides electric vehicles with battery replacement, battery rental and other services. People can buy batteries without having to buy batteries and save half the money for car purchases. It takes only 5 to 8 minutes each time the battery is replaced, greatly improving the convenience of electric vehicles.

In this regard, Mr. Wang said that the prerequisite for the realization of the lease battery is to achieve a unified battery size standards, "otherwise the standard is different, how to replace the battery installed." In addition, battery rentals should be operated independently by third parties.

However, this will inevitably bring about new problems. Guchanghua said: “The practice of Xiamen is a good idea.” But the problem is that the cost of battery rental is too high. Besides the construction of charging stations, there are also the purchase of batteries and consumption. Cost, the average enterprise can not afford it. "Who will do this?"

For Xiamen's approach, Wuhan Power Supply Company stated that at present, the company has not received a notice from the State Grid Corporation of China, and that “electric vehicles entering the station without charging only need to replace the battery” may currently only be promoted in some cities. If the Wuhan company receives the notification, The relevant charging station construction will start as soon as possible.
