P-CTTS1A-64CH 64-Channel Energy-Saving Formation Cabinet for Prismatic Aluminum-Shell Battery Cells
⚡ Key Benefit: PPCELL 64-Channel Energy-Saving Feedback Formation Cabinet is specially designed for high-volume prismatic battery formation and capacity grading, delivering ±0.05% FS accuracy, 90% energy feedback efficiency, and 64 independent channels for EV and ESS prismatic battery production.
Energy-Saving Feedback Formation Cabinet Product Overview
PPCELL 64-Channel Energy-Saving Feedback Formation Cabinet is a specialized piece of equipment designed to perform two essential processes on lithium batteries: formation and capacity grading. This equipment is mainly used for high-volume production lines of lithium-ion prismatic (square aluminum-shell) batteries for Electric Vehicles (EVs) and Energy Storage Systems (ESS). It supports multi-step formation profiles, high-temperature formation (30-50°C), and negative pressure formation (-10 to -95kPa) — covering the full range of prismatic cell manufacturing from pilot lines to gigafactories (100,000 to 1M+ cells/day).

FAQ — Frequently Asked Questions
Q1: What is the difference between a formation cabinet and a grading cabinet?
A: Formation is the initial charge/discharge process that activates the battery and forms the SEI (Solid Electrolyte Interphase) layer on the anode. Grading or capacity testing measures the actual capacity, OCV, and internal resistance to sort cells into performance grades. Our 64-channel cabinet integrates both functions into one system, supporting formation, grading, and capacity sorting.
Q2: How does energy-saving feedback technology work?
A: During the discharge phase, the energy normally wasted as heat in traditional resistive load testers is captured, converted, and fed back into the facility’s power grid. This reduces your total power consumption by up to 90% for discharge cycles, significantly lowering electricity costs. Our system achieves ≥90% feedback efficiency, with some models reaching up to 95% under optimal conditions.
Q3: What cell formats can this formation cabinet support?
A: The cabinet is specifically designed for prismatic aluminum-shell (square) cells used in EV and ESS applications. With adjustable voltage range (0-4.5V) and current (up to 150A per channel), it supports various capacities — from small prismatics (10Ah) to large-format power batteries (280Ah+).
Q4: What is negative pressure formation and why is it important?
A: Negative pressure formation applies a vacuum environment (0 to -95kPa) around the cell during the charge/discharge cycle. This removes gas bubbles generated inside the cell during the initial activation process, resulting in a more uniform SEI layer, better capacity retention, and reduced internal pressure — especially critical for large-format prismatic cells where gas accumulation can cause cell swelling.
Q5: Can the cabinet be integrated with my MES system?
A: Yes. Our formation cabinet supports RS485 and Ethernet (Modbus TCP) communication, providing real-time data upload — voltage, current, capacity, temperature, and test results — for full traceability and quality control. Centralized PC control with data management software supports multi-step formation profiles and automated grading based on voltage, capacity, and internal resistance.
