The operation of public charging infrastructure in China: the number of public charging piles increased by 44000 in October 2022 compared with that in September, with a year-on-year growth of 58.1%. As of October 2022, member units in the Alliance have reported a total of 1.68 million public charging piles, including 710000 DC charging piles and 970000 AC charging piles. From November 2021 to October 2022, about 51000 new public charging piles will be added each month.

Overall operation of charging infrastructure: from January to October 2022, the increment of charging infrastructure will be 2.091 million, of which the increment of public charging piles will increase by 109.0% year on year, and the increment of private charging piles built along with the vehicle will continue to increase by 391.4% year on year. As of October 2022, the cumulative number of charging infrastructure nationwide is 4.708 million, with a year-on-year increase of 109.0%.

With the development of digital currency and the progress of technology, the form of charging pile is also changing. From the initial coin operated charging mode, to card charging, code scanning charging, to inductive communication, the charging pile of electric vehicles is also making continuous progress. Charging pile equipment using 4G modules is expensive and requires the support of mobile networks. In some special places, such as basements, where the signal is weak or no signal, unless a communication base station is installed, the use of charging piles will be affected, which increases the cost of the product. Therefore, the application of Bluetooth BLE technology in charging piles arises at the historic moment.

The low-power Bluetooth charging pile uses Bluetooth BLE technology, scans the QR code of the charging pile with the mobile phone, and wakes up the charging pile on WeChat applet or app; The other is to use the Bluetooth identification function to automatically wake up the charging pile when the charging pile recognizes the mobile phone user information. The charging pile does not need to be connected to the network, and does not need complex wiring. It has strong flexibility and low construction cost; Effectively solve the reconstruction and upgrading of new/old residential areas or decentralized roadside charging piles, and effectively solve the traditional charging convenience.
