Mobile charging system and controlling method thereof

Abstract

The invention discloses a mobile charging system and a controlling method thereof. The mobile charging system comprises an energy storage battery and a battery management system, wherein the input end of the energy storage battery is connected to a recharging interface of equipment through a switch S1, the output end of the energy storage battery is connected to a charging interface of an automobile through a switch S2 and a switch S3, a DC / AC charging module is arranged between the switch S2 and the charging interface of the automobile, an auxiliary power supply is arranged between the switch S3 and the charging interface of the automobile, the battery management system is connected with a switch S4, a contact A of the switch S4 is connected to the recharging interface of the equipment, and a contact B of the switch S4 is connected to the output end of the auxiliary power supply, a mobile charging controller is arranged between the switch S3 and the auxiliary power supply, the mobile charging controller is connected with a switch S5 used for selecting operation states, and the mobile charging controller can be used for controlling the switches S1-S4 through the operation state of the switch S5. According to the mobile charging system and the controlling method thereof, standby loss of the system is reduced, over discharge of the battery is prevented, the service life of the battery is prolonged, and meanwhile the problem of time sequence in the process of automobile charging and equipment recharging can be solved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to a mobile charging system and a control method thereof. Background technique [0002] With the progress of society and the enhancement of environmental protection awareness, electric vehicles are gradually favored because they are powered by on-board power supplies and can solve the problem of exhaust emissions from fuel vehicles. However, during the use of electric vehicles, the following situations often exist: the battery power of the electric vehicle is insufficient during driving, and it cannot reach the charging station for charging; the parking lot with relatively insufficient charging spaces cannot meet the charging needs of users. The capacity of the power grid in the old community is not enough to build DC charging piles and meet the needs of users for fast charging. Contents of the invention [0003] The purpose of the present invention ...
