Problems solved by technology

[0003] In the process of studying the application of lithium batteries, it is found that the existing power lithium battery charging technology has the following problems: the development trend of power lithium batteries is towards high voltage and high capacity, and there is no fixed standard for battery capacity and voltage, which makes the battery charger very difficult. Difficult to use universally, the cost of developing a charger for each set of batteries is too high; due to the inherent characteristics of lithium batteries, different control strategies need to be adopted in the charging phase, constant voltage and constant current charging switching control, the control method is complicated

Abstract

The invention provides a charging device. The charging device comprises a rectifying unit, a control unit, a charging plug and a charging communication module, wherein the rectifying unit is used for converting external alternate current from an external power supply into direct current and outputting the direct current through the charging plug; the charging plug is connected to a charging port of to-be-charged equipment and used for charging the to-be-charged equipment; the charging communication module is connected to a communication control port of the to-be-charged equipment, the control unit and the rectifying unit and used for transmitting battery state information of the to-be-charged equipment to the control unit and transmitting a control signal from the control unit to the rectifying unit; and the control unit is connected to the charging communication module and the rectifying unit and used for generating the control signal according to the battery state information of the to-be-charged equipment and controlling the current and / or voltage of the direct current output by the rectifying unit according to the control signal. By adopting the technical scheme provided by the invention, power lithium batteries in different specifications can be charged, and the output current and voltage can be automatically controlled in the charging process.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a charging device. Background technique [0002] So far, in construction machinery and port machinery, the application of lithium batteries is just in the exploratory stage, and how to charge the applied power lithium batteries has not been studied in depth. [0003] In the process of studying the application of lithium batteries, it is found that the existing power lithium battery charging technology has the following problems: the development trend of power lithium batteries is towards high voltage and high capacity, and there is no fixed standard for battery capacity and voltage, which makes the battery charger very difficult. Difficult to use universally, the cost of developing a charger for each set of batteries is too high; due to the inherent characteristics of lithium batteries, different control strategies need to be adopted in the charging phase, constant ...
