Problems solved by technology

However, after the electric vehicles produced according to Chinese standards are exported to the United States or Europe, they cannot be charged by local charging piles.
[0004] It can be seen that the existing technology cannot realize free charging between electric vehicles and charging piles using different charging protocol standards

Abstract

The invention relates to the technical field of electric automobile charging and discloses a charging conversion method, device, system, a computer device and a storage medium. The charging conversionmethod comprises the following steps of: receiving a charging pile signal, and analyzing to obtain a charging mode of the charging pile; respectively calling charging protocols corresponding to the charging pile and the automobile charging system, carrying out charging handshake with the charging pile according to the charging protocol corresponding to the charging pile, and carrying out charginghandshake with the automobile charging system according to the Chinese standard charging protocol corresponding to the automobile charging system; and receiving the charging parameter information ofthe power storage battery which is sent after the handshaking of the automobile charging system is successful, and sending the charging parameter information of the power storage battery to the charging pile after the handshaking is successful in a European or international standard charging protocol form, wherein the charging parameter information is used for configuring the output parameters ofthe charging pile. The charging conversion method can carry out conversion between the Chinese standard charging protocol and the European or international standard charging protocol, thereby promoting the use of the electric automobile.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a charging conversion method, device, system, computer equipment and storage medium. Background technique [0002] [Electric vehicles are currently relatively green and energy-saving means of transportation, mainly powered by on-board power supplies, so they usually need to be charged. Fast charging technology can charge electric vehicles in a relatively short period of time, thereby solving the problem of long charging time for electric vehicles. [0003] Due to the relatively large current and voltage in the fast charging process, the charging protocol is usually designed between the charging pile and the car to ensure the safety of the charging process. At present, the charging protocol standards used in various countries or regions are different, including Chinese standards (GB-T-27930), American standards (SAE J1772), European standards (DIN 70121) and inte...
