Abstract

The invention discloses a multi-frequency-band intelligent charging pile system supporting car networking. The multi-frequency-band intelligent charging pile system is characterized in that a DSRC radio frequency chip is embedded in a communication module and supports receiving and sending of a 5.9 GHz IEEE802.11p data package, and a multi-frequency-band wireless communication access mode is formed by the DSRC radio frequency chip, a 4G / 3G / GPRS communication module and a Zigbee radio frequency chip in a collaboration mode; the communication relay function of a communication infrastructure in the car network and the core network accessing function are achieved, state data and interest information can be interchanged between the system and an electric car which is provided with a DSRC radio frequency chip, an uplink supports the function of collecting battery margin data, vehicle running data and other state data, and a downlink supports the function of issuing battery charging privilege, battery charging schedule guiding, equipment failure early warning and other interest information; a plurality of car network building modes based on a mobile public network, a vehicle-mounted ad hoc network, a vehicle-mounted wireless sensing network and a hybrid network are supported; two USB interfaces capable of supporting expanding application of other newly-developed wireless communication technologies in future are reserved in the system.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging systems, in particular to a multi-band intelligent charging pile system supporting Internet of Vehicles. Background technique [0002] Smart charging piles are widely used charging infrastructure for electric vehicles, and are also a core member of building a smart charging and swapping service network. Compared with traditional charging piles, in addition to meeting the basic functions of electric vehicle charging, smart charging piles can participate in the construction of intelligent charging and swapping service networks by integrating a variety of information communication and automation technologies, providing charging and swapping facilities, and electric vehicle battery power. , Real-time monitoring and scheduling of operating status of charging and swapping stations, metering and billing, asset management and other functions. From the perspective of the hardware system ...
