Charging intelligent control-based power battery pack management and control system

Abstract

The invention relates to the technical field of manufacturing of a battery pack, and specifically discloses a charging intelligent control-based power battery pack management and control system. The power battery pack management and control system is characterized by comprising a shell; a controller, a charging circuit, a radio frequency reader-writer and a radio frequency antenna are arranged inthe shell, wherein the radio frequency reader-writer is connected with the radio frequency antenna; the radio frequency reader-writer is connected with the controller; the power battery pack management and control system is also provided with a display and an operation keyboard, wherein the display and the operation keyboard are connected with the controller separately; the display and the operation keyboard are both arranged on the exterior of the shell; the power battery pack management and control system is also provided with an alternating current and direct current compatible type preceding stage circuit connected with the controller; and the alternating current and direct current compatible type preceding stage circuit is provided with a rectifying circuit, an alternating current voltage detection circuit, a direct current voltage detection circuit, a PFC circuit, a DC / DC voltage boosting circuit and a pulse width modulation integrated circuit. By virtue of the power battery packmanagement and control system, the problem of difference existing in charging of batteries of different specifications can be solved effectively; and by adopting the radio frequency reading-writing mechanism for identification, high speed and accurate identification are achieved.

Description

Technical field: [0001] The invention relates to the technical field of battery pack manufacturing, in particular to a management and control system for power battery packs based on charging intelligent control. Background technique: [0002] With the advancement of science and technology and the development of battery technology, electric energy is more and more widely used as power. At this stage, power batteries include lead-acid batteries and lithium-ion batteries. As we all know, each battery has its own charging characteristics, so a large amount of charging A device is a device equipped with a charger. Different devices cannot be charged with the same charger. The reason is that different devices use different charging voltages and charging currents (for example, the charging voltages of different models of mobile phones are 4.4V and 5V respectively), that is The charging curve is inconsistent, and if you try to charge it forcibly, it will damage the device. When ele...
