Supercapacitor management device and system for charging and discharging with the same port control

Abstract

The invention provides a charge and discharge same-interface control supercapacitor management apparatus and a system thereof. The apparatus comprises an acquisition detection module connected with single supercapacitors in a supercapacitor module and used for acquiring the voltage, current and temperature of the single supercapacitors; a main controller connected with the acquisition detection module and used for determining the charge and discharge state of the single supercapacitors according to the voltage and the current and controlling the motion of the acquisition detection module, a charge and discharge control module, and a data interaction module; a charge and discharge control module connected with the main controller, a charging controller of the supercapacitor module and a discharge controller of the supercapacitor module and used for controlling the on-off state of the charging controller and the discharge controller according to the charge and discharge state; and a data interaction module connected with loading equipment, the main controller, and the charge and discharge control module and used for data interaction between the acquisition detection module and the charge and discharge control module. According to the apparatus and the system, the energy loss during charge and discharge same-interface control can be reduced.

Description

technical field [0001] The invention relates to the technical field of energy control and management of supercapacitors, in particular to a supercapacitor management device and system for controlling charging and discharging through the same port. Background technique [0002] Supercapacitors are currently the most widely used energy storage devices. Due to the characteristics of small resistance, long life, fast charging, safety and reliability, supercapacitors have attracted much attention from all walks of life. However, in practical applications, due to the low voltage and capacity of a single supercapacitor, it needs to be connected in series or in parallel to be used as a supercapacitor module. There are certain differences between different supercapacitors in the supercapacitor module. During the charging and discharging process, a certain supercapacitor may be overcharged, overdischarged or overheated before other supercapacitors. Therefore, in practical applicatio...
