Non-contact power supply supercapacitor rgv charging protection method

Abstract

The non-contact power supply supercapacitor RGV charging protection method described in the present invention aims at the charging circuit of the existing noncontact power supply supercapacitor, and accordingly proposes a charging protection control circuit and a protection method based on the circuit, in order to realize the supercapacitor charging circuit The control methods of fast charging and start-stop control, reverse charging protection and zero-battery automatic activation charging and protection realize the prospect of supercapacitor application in the RGV industry and effectively increase the overall safety performance of supercapacitor RGV charging. The charging protection method is based on the supercapacitor charging circuit connected to the RGV body connected to the charging protection circuit. The supercapacitor RGV charging protection circuit includes terminal X1, insulating terminal MC, reverse charging protection module, fast charging start-stop switch module, zero battery Automatic activation of the charging module and zero battery automatic activation of the charging and protection module.

Description

technical field [0001] The invention relates to a circuit design and a control method for corresponding safety protection applied in the charging process of a non-contact power supply type supercapacitor RGV, and belongs to the field of electrical design. Background technique [0002] With the rapid development of e-commerce logistics and production automation technology, the scale of automated logistics systems and automated warehousing systems is getting larger and larger. Non-contact power supply supercapacitor smart RGV has become one of the indispensable equipment for automated logistics systems and automated warehousing systems. [0003] The existing RGV power supply can be divided into trolley line power supply and super capacitor (hereinafter referred to as super capacitor) power supply, and RGV super capacitor power supply is better than trolley line power supply in terms of large current charge and discharge capacity, high reliability, maintainability, convenience a...

Problems solved by technology

In the existing circuit design, it is still impossible to solve the problem of charging the supercapacity in a short time by using the slow charging circuit activated automatically by zero power, and the circuit design cost is relatively large and cannot be designed according to the circuit design of fast full and large current; 4) the existing The protection of the zero-battery charging circuit has not yet been related to the design of adding a current-limiting resistor to ensure the safety of the circuit. At the same time, it is also necessary to consider the failure of the RGV body controller to start fast charging and disconnect the zero-battery activation circuit in time, such as abnormal circuit temperature and occurrence of How to quickly and automatically disconnect the charging circuit to protect the charging circuit when the line temperature is abnormal, and how to automatically restore the charging circuit after the temperature is normal
