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.
