5V 0.5A 128 Channels Hot Press Formation Machine for Polymer Battery Cells

I. Equipment Overview

1. Function (Principle)

This equipment is primarily used for the formation of polymer battery cells under high-temperature and pressure conditions. It helps to form a denser SEI film, enhance capacity utilization, and improve capacity consistency. The system supports large current charging, which shortens formation time and reduces the battery production cycle.

The machine integrates the hot press fixture and formation system into one unit. It consists of a 128-channel formation power supply and one set of fixture.

2. Main Functions

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.

6. Operating Procedure

Power On → Manually open cabinet door → Insert batteries into fixture A → Set parameters for fixture A → Fixture A presses down and starts process → Remove batteries manually after fixture A finishes...

7. Equipment Features

1. Compatible with cell thicknesses from 2.5–9 mm without needing fixture adjustments or tab block replacement

2. Fixture aluminum plates are 17 mm thick grid-structured lightweight aluminum, offering good strength and no deformation

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.)
