Embodiment 1

[0038]In this embodiment, an electric vehicle charging device suitable for public transport or logistics stations is specifically provided. The electric vehicle charging device includes four charging guns, so that: the four charging guns are A charging gun, B charging gun, C charging gun and D charging gun, A charging gun, B charging gun, C charging gun and D charging gun can simultaneously charge multiple vehicles at the same time, and the four charging guns can be flexibly arranged to improve the utilization efficiency of the charging guns .

[0039] It also includes an AC power supply and protection device, a power supply module, a switch matrix and a control module. The switch matrix includes eight charging path groups, and each of the charging path groups is provided with four charging paths, and the four charging paths are connected to the four charging paths respectively. The charging guns are one-to-one corresponding and electrically connected, and relays are provided ...

Embodiment 2

[0048] On the basis of Embodiment 1, this embodiment provides an electric vehicle charging method suitable for public transportation or logistics stations, which is applied to the above-mentioned electric vehicle charging equipment suitable for public transportation or logistics stations, and the method includes:

[0049] (1) Divide the working hours of electric vehicle charging equipment, and define daytime hours and nighttime hours respectively, for example: the daytime hours are set from 8:00 am to 9:00 pm, or other time periods; from 9:00 pm to the next morning Eight o'clock is the night time period; if the current time period is in the day time period, then enter (2); if the current time period is in the night time period, then enter (3);

[0050] (2) The control module performs priority sorting according to the time sequence of each charging gun inserted into the vehicle, allocates the number of charging modules connected to each charging gun according to the priority ran...

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to an electric vehicle charging device and method suitable for public transportation or logistics stations. Background technique [0002] In recent years, electric vehicles have been strongly supported and promoted by the government due to their zero-emission characteristics, and their applications are becoming more and more widespread. [0003] Due to the characteristics of fixed driving routes and controllable mileage of public transport and logistics vehicles, electric vehicles are being rapidly applied. At present, most of the charging equipment operating in the market is mainly aimed at fast charging and serving social vehicles, but the daily dispatch and operating costs of buses and logistics vehicles cannot be well balanced, as follows: [0004] (1) The main purpose of the existing DC charging equipment is to meet the daily or temporary rapid power re...
