Battery format into a charging and discharging machine

The battery formation refers to a process of charging and discharging a secondary battery.

The formation of the battery is the first process of charging the newly produced battery! It is an important part of the life of the battery. The lithium battery requirements are very strict. It is divided into two stages: constant current charging and constant voltage charging. The small current trickle charge makes the battery terminal voltage to the discharge termination voltage and then the constant current is charged until the battery terminal voltage reaches the constant voltage charging voltage, and then the constant voltage is charged until it is full!

Specifically, the packaged secondary battery is charged with a small current to activate the material activity, and a protective film is formed on the surface of the anode to protect the entire chemical interface. The specific practices vary from manufacturer to manufacturer! Deeper, it involves the use of confidential documents. Hope it helps you!

The formation is to completely dry the raw plate (not formed into a plate) in a dilute sulfuric acid electrolyte for electrolysis, after oxidation and reduction, respectively, the lead oxide of the positive plate is changed to lead dioxide and the oxidation of the negative plate The process by which lead changes to spongy metal lead. After solidification and drying, the active material composition of the electrode plate is roughly: positive electrode plate: lead oxide, basic lead sulfate, lead and lead dioxide (as a component of red dan (Pb3O4) when used) negative electrode plate: lead monoxide, sulfuric acid Lead, lead, inorganic expansion agents, organic expansion agents and antioxidants. Most of these active substances must be converted into lead dioxide on the positive plate and spongy metal lead on the negative plate. The formation process is an electrochemical transition of the composition of the solidified plate to the working material of the positive and negative plates. The substance solidified by the positive electrode plate is transferred to the electrolytic solution by sulfate ions, and receives oxygen from the negative electrode plate material, and is oxidized to lead dioxide. At the same time, the sulfate ion is transferred from the material solidified by the negative electrode plate to the electrolyte and transfers oxygen to the positive electrode plate material. There are two methods for forming a plate for a lead-acid battery: a method for forming a groove into a groove (commonly known as "externalization") and a method for forming a battery (commonly known as "internalization"). Regardless of the method of formation, it usually takes 2 to 3 days from the start of formation to the termination of formation.

WDY1 series lead-acid battery into a charging and discharging machine (hereinafter referred to as charging and discharging machine) uses advanced double closed-loop PID feedback control technology to set the working voltage and working current of the charging and discharging machine. The microcontroller can give the voltage and current signals according to the program setting and the DC side voltage and current signals fed back by the closed-loop system for comparison and calculation. After adjusting the circuit, the phase-shifting chip outputs a trigger pulse to trigger the thyristor to rectify and contact. The device performs switching between charging and discharging. When the device is running, the system feedbacks the DC side voltage and current signals in real time. On the one hand, it compares with the set value to automatically adjust, so that the voltage and current parameters remain consistent with the set value. On the other hand, the above signals are transmitted to the microcontroller and calculated. The actual value is displayed on the LCD panel in real time.

It also has fault protection functions such as overvoltage, under voltage, current interruption, under current and over temperature. Safety during the formation process

1. Over-current protection: Automatic protection when the output current is higher than 5% of the set current.

2. Undercurrent protection: Automatic protection when the output current is lower than 5% of set current.

3. Overvoltage protection: Automatic protection when the output voltage is higher than 5% of the set voltage.

4. Under-voltage protection: Automatic protection when the output voltage is lower than 5% of the set voltage.

5. Cut-off protection: automatic protection when the output current is less than 2% of the rated current.

6. Over-temperature protection: When the temperature of the radiator inside the chassis exceeds 110 °C, it will automatically shut down and protect.

The process can be edited and sent by the host computer, or the process can be directly edited by the lower computer. The process program is stored on the computer hard disk and can be stored in tens of thousands of pieces and can be called at any time. The host computer can store the collected loop operation data in real time, and can import the data into Excel2003 or 2007 table processing or export and print the original data.

Power-down protection function: If accidental power-off occurs during charging/discharging, automatically save the set charging/discharging parameters and the data collected during charging/discharging. After the call, it will automatically run from the breakpoint. The /discharge data is stored continuously without damage to the device.

Data acquisition: The data can be collected at a faster frequency (the data collection period can be set by itself), which is convenient for battery pack analysis.

Data processing: The data collected by the host computer through the “data analysis” module (random configuration) is processed to generate various curves that reflect the battery pack (current/voltage/electricity) and can be printed.
