Consistency Analysis Method of Electric Vehicle Charging Pile Business Logic Based on Sequential Logic

Abstract

The invention discloses a sequential logic-based business logic consistency analysis method for electric vehicle charging piles. Aiming at potential safety hazards in the data transmission process of the electric vehicle charging pile monitoring system, a server-side data reliability verification method is proposed to effectively prevent transmission errors. Malicious attacks where charging parameters lead to incorrect adjustments to the grid. This method is mainly to correlate the feedback data of the charging pile with the feedback data of the user's mobile terminal in time series, and jointly verify the multi-modal data, so as to judge whether there is data anomaly caused by hacking, and realize the business of the charging pile monitoring system based on time series logic. Logical consistency security check.

Description

technical field [0001] The invention belongs to the field of smart grid security, and relates to an analysis method for electric vehicle charging pile power terminals, in particular to a sequential logic-based business logic consistency analysis method for electric vehicle charging piles. Background technique [0002] The charging modes of electric vehicles mainly include fast charging, conventional charging and battery pack replacement. Multi-user charging piles are mainly for conventional charging modes and are generally used in parking lots. There are two main impacts of electric vehicle charging on the power grid: (1) In densely populated urban areas, there is a certain limit on electricity consumption, and centralized charging of electric vehicles is a relatively large load on the entire power grid. Consider the balance of power consumption when charging on a large scale. (2) For the parts with more loads at the power consumption end, the alternating power supply betw...

(2) For the part with a lot of load on the power consumption end, the alternating power supply between the three phases will produce certain harmonic effects, and the connection of large-scale charging piles to the power grid will cause relatively large dynamic pollution to the entire power grid

[0005] The security design of the electric vehicle charging pile monitoring system mainly exists in the data transmission process. Since the charging pile and the user's mobile terminal are often in the external network environment, there are extremely high security risks, especially the charging parameters fed back during the charging process of electric vehicles. Tampering will lead to wrong adjustment of the power grid, so it is necessary to improve the security of this link to improve the security mechanism of the system
