The ATOMFAIR EFC-8639 is a high-voltage lithium-ion battery formation system requiring strict electrical and environmental constraints for safe operation. It demands a three-phase five-wire 380VAC±15% input with power factor above 0.99 and total harmonic distortion below 5% to ensure grid compliance and equipment longevity.
- Input Power Requirements: The system must be connected to a three-phase five-wire 380VAC±15%, 50Hz±10% power source with a maximum withstand input voltage of 450VAC for up to one hour static.
- Operating Temperature Range: The ambient operating temperature must be maintained between 0°C and 45°C to ensure reliable performance and prevent thermal stress.
- Battery Side Impedance: The battery side impedance must exceed 100 kΩ to maintain safety and measurement accuracy during formation and grading cycles.
- Unattended Operation Safety: Multiple software and hardware protection mechanisms are integrated to support long-term unattended operation, but all safety protocols must be verified before initiating automated cycles.
- Battery Voltage Compatibility: Only lithium-ion battery cells with charge voltage within 0–5 V and discharge voltage within 1.2–5 V are compatible with this system.
This procedure outlines the essential steps to safely set up and begin a formation or grading cycle on the EFC-8639 cabinet. Follow these steps in order to ensure proper electrical connection, channel configuration, and battery loading.
Required Equipment: Three-phase five-wire 380VAC power source
- Connect Power Supply
Verify and connect the system to a three-phase five-wire 380VAC±15% power source with proper grounding and overcurrent protection. - Configure Communication Interface
Connect the Ethernet communication interface to a control network and configure the IP settings for remote monitoring and data acquisition. - Set Channel Parameters
Program each independent DSP-controlled channel with the desired charge/discharge current between 20 mA and 12 A and voltage limits within 0–5 V for charge and 1.2–5 V for discharge. - Load Battery Cells
Insert lithium-ion battery cells into the cabinet ensuring correct polarity and that the cell voltage and chemistry are within the specified ranges. - Initiate Formation Cycle
Activate the formation or grading cycle via the control software and monitor the LED panel for real-time status and any fault indications.
What is the actual energy savings and total harmonic distortion (THDi) performance of the Atomfair EFC-8639 formation and grading cabinet?
The EFC-8639 achieves 50% energy savings compared to traditional equipment under identical working conditions, with a total harmonic distortion (THDi) of less than 5% and a grid power factor exceeding 0.99. This reduces power consumption to half and lowers workshop ambient temperature by 5–15°C, decreasing cooling equipment investment.
What are the voltage and current ranges for charging and discharging lithium-ion cells with the EFC-8639, and what is the response time?
The EFC-8639 supports a battery voltage range of 0–5V for charging and 1.2–5V for discharging, with a charge/discharge current range of 20 mA to 12 A per channel. The current rise time and channel start time are both 50 ms at 90% load, enabling rapid and precise control for formation and grading processes.
What are the electrical infrastructure and environmental requirements for installing the EFC-8639?
The EFC-8639 requires a three-phase five-wire 380VAC±15%, 50Hz±10% input power supply, with a maximum withstand input voltage of 450VAC for 1 hour (static). It operates within an ambient temperature range of 0–45°C and features a battery side impedance exceeding 100 kΩ, ensuring safe and stable operation in research and production environments.
The EFC-8639 is a 256-channel, 5V12A lithium-ion cell formation and grading cabinet with independent DSP control per channel, delivering 50% energy savings and THDi below 5% for reduced thermal load and grid impact. Its 20 mA–12 A current range and 50 ms response time support precise cycling across cylindrical, pouch, and prismatic cells, though it requires a dedicated 380VAC three-phase five-wire supply and 0–45°C operating environment.
Positive
- 50% energy savings with reduced thermal load: The system consumes only 50% of the power of traditional equipment under identical conditions, lowering workshop ambient temperature by 5–15°C and reducing cooling infrastructure costs.
- Independent DSP control with wide current range: Each of the 256 channels is independently controlled by an industrial-grade DSP, enabling single-point programming across 20 mA–12 A with 50 ms response time, suitable for precise formation and grading of various cell formats.
Trade-offs
- Requires three-phase five-wire 380VAC supply: The system operates on 380VAC±15% three-phase five-wire input at 50Hz±10%, necessitating dedicated industrial power infrastructure that may not be available in all laboratory settings.
- Operating temperature limited to 0–45°C: The specified operating range of 0–45°C requires controlled ambient conditions; operation outside this range may affect performance or require additional environmental management.
