This device is mainly used to form polymer battery cells in high temperature and high pressure environments. Its main functions include promoting the formation of dense SEI film, improving capacity utilization, and enhancing capacity consistency. In addition, the system supports high current charging, effectively shortening the formation process and shortening the overall battery production cycle.
This machine combines hot pressing fixtures and forming systems into an integrated unit, including a 128 channel forming power supply and a set of fixtures.
The equipment is composed of six major systems: temperature control, over/under-temperature alarm, over/under-voltage alarm, pressure control, formation cabinet system, and fixture mechanism.
It features: Independent temperature control for each board layer, pressure control, charge/discharge functions, overcharge/discharge protection, reliable contact between battery tabs and contact points, data connectivity, data storage upon process completion, voltage sorting after charging, capacity sorting after discharging, and smoke alarm system.

III. Main Software Functions
1. Working modes include: constant current charging, constant current/constant voltage charging, constant current discharging, resting, and cycling;
Charge/discharge cut-off conditions: voltage, time, end current, and end capacity.
2. Formation steps support power-off resume, manual pause/resume, software shutdown resume, communication interruption resume, and abnormal stop resume.
3. Stores all step curves for each battery. Test data is stored and can be viewed at any time for both current and historical data of each channel.
Data and curve are presented correspondingly in two formats, and support exporting to Excel individually or in batches.
Additionally, automatic data export can be configured upon test completion.
4. Multiple battery inspection interfaces available: graphical display, comprehensive data, categorized data, and error display.
5. Supports protection and alarm functions for all steps, including voltage, current, temperature, and pressure anomalies.
6. Minimum computer system requirements:
CPU: PII/300 or above, memory: ≥1GB, hard disk: ≥80GB,
Display: EGA/VGA, OS: Microsoft™ Windows 2000 or above,
One available USB serial port, mouse and keyboard.
7. Operation software is included; users must provide their own computer.
8. Protection Functions:
(1) Overvoltage, undervoltage, overcurrent, undercurrent, and overcapacity protection via software
(2) Configurable protection ranges for voltage and current, with alerts and event logging
(3) Alarm lights for temperature and pressure over-limit, with status indication
(4) Emergency stop button: when pressed, fixture remains clamped and system power is cut
(5) Smoke detector installed: system will trigger buzzer alarm upon detection
Three-color indicator light status:
(1) Yellow: Standby (fixture not pressed)
(2) Green: In process (pressing and charging)
(3) Red: System fault (over/under temperature, over/under voltage, smoke, communication fault, etc.)
