Charging communication control device and charging communication control method

Abstract

The invention relates to a charging communication control device and a charging communication control method. The charging communication control device comprises two communication conversion controllers, each communication conversion controller comprises a PLC (power line carrier communication) signal receiving and transmitting unit and a charging communication protocol signal receiving and transmitting unit, wherein the charging communication protocol signal receiving and transmitting units are used for receiving and transmitting charging communication protocol signals; a conversion unit used for realizing conversion between the charging communication protocol signal and the PLC signal; wherein the two communication conversion controllers are respectively arranged at a charging pile end and a vehicle end, the pile end communication conversion controller is used for transmitting a charging communication protocol signal with the charging pile end, and the vehicle end communication conversion controller is used for transmitting a charging communication protocol signal with the vehicle end; the pile end communication conversion controller and the vehicle end communication conversion controller are further used for establishing network connection through PLC signals after the charging pile end and the vehicle end form electric contact, and communication between the pile end and the vehicle end is achieved.

Description

technical field [0001] The invention relates to the field of communication control, in particular to a charging communication control device and a charging communication control method. Background technique [0002] Currently, charging methods for electric vehicles include two methods: a plug-in type and an electrode plate contact type. Due to the limitation of the charging gun and the electric vehicle socket, the charging current of the plug-in charging pile is relatively small during charging, so the charging is slow and the charging time is long. Using the electrode plate contact type charging pile, the charging electrode plate can be installed on the top of the charging pile. When the vehicle needs to be charged, it stops at the corresponding position of the charging pile. The charging guide rails are contacted for charging, which can realize high-power and high-current transmission, and can be used as a main charging method for electric buses. [0003] In the current ...

AI Technical Summary

Problems solved by technology

For the charging method using the electrode plate butt joint type, since the charging gun is banned, in order to realize the charging communication protocol of CAN communication, an additional communication cable needs to be added, which increases the complexity of the system and reduces the flexibility of charging.
