Embodiment 1

[0038] The present invention provides a method for quickly adjusting battery current, such as figure 2 and image 3 shown, including the following steps:

[0039] Step 1, the monitoring terminal samples the real-time output current of the battery pack and the real-time output voltage of the charging module, and sends a voltage regulation command to the voltage regulation management module according to the real-time output current and real-time output voltage;

[0040] Step 2, after receiving the voltage regulation command, the voltage regulation management module inputs the first voltage signal to the battery pack;

[0041] Step 3, after the battery pack receives the first voltage signal, determine the current information and battery pack performance of the battery pack, and transmit the current information and battery pack performance to the PID controller;

[0042] Step 4: The PID controller adjusts the PID control parameters according to the performance of the battery pa...

Embodiment 2

[0065] The difference between this embodiment and the first implementation is that a battery ammeter is added between the battery pack and the PID controller, and the battery record table is used to record the current information output by the battery pack each time, which is convenient for the staff to preview, query and check the current information of the battery pack .

[0066] Such as Figure 5 As shown, the monitoring terminal, charging module, battery pack, PID controller, battery recorder and voltage regulation management module are constructed into a high-voltage DC power supply system. First, the monitoring terminal samples the real-time output current of the battery pack and the real-time output voltage of the charging module. And according to the real-time output current of the battery pack and the real-time output voltage of the charging module, it is judged whether the voltage regulation management module needs to regulate the battery pack. pressure command;

Abstract

A method for quickly regulating battery current belongs to the field of high-voltage DC power supplies and includes sending a voltage regulation instruction to a voltage regulation management module according to real-time output current of a battery pack sampled by monitor terminal and real-time output voltage of charging module, regulating the voltage of the battery pack by the voltage regulationmanagement module according to voltage regulation instruction ; enabling the battery pack to feed back the battery pack performance and current information to the PID controller; enabling The PID controller to adjust the PID control parameters according to the performance of the battery pack and feed back the regulated voltage difference to the voltage regulating management module; and If the regulated voltage difference is not zero, enabling the voltage regulation management module to continue to regulate the voltage. The voltage regulating management module regulates the voltage of the battery pack after receiving the voltage regulating instruction sent by the monitoring terminal, The output of PID controller is more stable by adjusting PID control parameters according to the performance of battery pack, which avoids the large current oscillation of battery pack, improves the utilization rate of battery pack and prolongs the life of battery pack.

Description

technical field [0001] The invention relates to the field of high-voltage direct current power supplies, in particular to a method for rapidly adjusting battery current. Background technique [0002] At present, due to the advantages of reliable power supply and effective energy saving, the high-voltage DC power supply system is widely used in the field of communication power supply. Among them, the high-voltage DC power supply system includes a monitoring terminal, a charging module and a battery pack. The charging module includes a mains input and a rectifier. The high-voltage DC power supply system can use a charging module or a battery pack or a charging module and a battery pack to supply power to the load at the same time. [0003] Due to the limitations of the existing technology, the adjustment of the battery current is single at present, and the PID (Proportion-Integral-Derivative, proportional-integral-derivative) controller is only used to control the charging pro...
