Detailed Description
The invention is further explained below with reference to the drawings:
as shown in fig. 1 to 3, a portable energy storage power supply with a high-frequency switching power supply includes a main control module 1, an output module 2, a functional module 3, a communication module 4, a charging module 5, a power management module 6 and a power module 7, wherein the output module 2, the functional module 3, the communication module 4, the charging module 5 and the power management module 6 are respectively connected with the main control module 1, the charging module 5 is connected with the power management module 6, the power management module 6 is connected with the power module 7, the charging module 5 includes a charging main control module 51, an input module 53 and an overvoltage protection module 52, and the input module 53 is connected with the charging main control module 51 through the overvoltage protection module 52.
The type of the main control module is as follows: PIC16F 19197.
The model of the charging main control module is as follows: PIC16F 1779.
The overvoltage protection module 52 comprises a temperature fuse 521, an SCR protection module 522 and an overvoltage detection module 523, the temperature fuse 521 is connected with the input module 53, the temperature fuse 521 is further connected with the SCR protection module 522, and the SCR protection module 522 is connected with the charging main control module 51 through the overvoltage detection module 523.
The thermal fuse 521 is also called a thermal fuse (national standard GB9816.1-2013) and is a temperature-sensitive circuit breaker. The temperature fuse can sense overheating generated in abnormal operation of electric and electronic products, so that a loop is cut off to avoid fire. When the input power is large, the thermal fuse 521 will automatically fuse to protect the lithium battery.
This implementation is through setting up SCR protection module 522 and temperature fuse 521, detects input voltage when overvoltage detection module 523, and after detecting the voltage overvoltage, SCR protection module just can make the short circuit to ground generate heat, and the temperature will blow temperature fuse 521 to play the effect of protection lithium cell.

The solar charging input interface 533 is a 1327 port input interface or a solar charging anderson input interface.
When the input module 53 has multiple inputs, the back-to-back MOS transistors are turned on when the input voltages are the same, that is, the lithium battery is charged (the first MOS transistor 534, the second MOS transistor 535, and the third MOS transistor 536 are all turned on), and when the input voltages are different, the solar charging input interface 533 is preferentially turned on for charging because the interface is a large-current charging interface.
In the prior art, if the diodes are used for separation, the path cannot be selected for charging, and only the path with high output voltage is automatically selected for charging, so that the efficiency is poorer than that of an MOS (metal oxide semiconductor) tube.
