Abstract

The invention relates to a quick charging device which is mainly composed of a main control panel, a touch liquid crystal display screen, a network communication module, a GPS module, an AC-DC module,a relay module, a charging terminal, a bi-directional DC-DC module, an energy storage unit and an RFID reader-writer. The invention further relates to a quick charging system which comprises the quick charging device and further comprises a fixed Bluetooth module and a to-be-charged device. The invention further relates to a charging control method which uses the quick charging system and mainlyincludes the recognition step, the power output step or the reversely charging step. The quick charging device and system and the charging control method have the beneficial effects that charging is quick, a quick charging mode conducted through a power lithium battery and the like is used, the energy storage unit such as a super capacitor as a representation is added to the charging device, the to-be-charged device can be charged through larger power, and the influence on the input end is reduced; recognition is automatic, and the to-be-charged device and the quick charging device can be matched; and the system can reversely charge the quick charging device.

Description

technical field [0001] The invention relates to the field of charging system and management technology, in particular to a fast charging device, system and charging control method. Background technique [0002] The conventional charging method is to charge the energy storage device with a current of 0.1C-0.5C. The charging time of this charging method is as long as several hours. In order to achieve fast charging, the charging current must be increased, especially in the early stage of charging. The current is generally 2C-5C. The conventional method is to equip a high-power switching power supply to provide a large current, resulting in a higher cost of the charging equipment, and in order to fully charge the battery, the current changes greatly during the charging process, which leads to a high power consumption of the charging equipment. The changes are also relatively large, forming large fluctuations on the power grid and affecting the operation of the power grid. [0...
