JH5V50A-48CH Channel-Isolated Battery Charge/Discharge Test Cabinet
1. Single-point independence: Each channel can be configured with independent charge and discharge settings, offering flexibility and convenience. 2. Channel isolation: Each channel is electrically isolated from the others, with no shared ground; individual cells within a battery pack can be charged or discharged independently or in series‑parallel configurations. 3. Powerful software with a user-friendly human–machine interface. 4. Four-wire output interface for high measurement accuracy. 5. Modular design for easy maintenance. 6. Energy regeneration: Discharge energy is fed back to the grid, promoting energy efficiency and environmental protection. 7. Comprehensive protection features, including overvoltage, reverse polarity, overcurrent, short circuit, overheating, and cross‑connection (unintended parallel connections among series‑connected cells). 8. Channels can perform group‑level balancing as well as individual cell balancing. 9. Capable of testing the full range of lithium‑ion batteries—including lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, ternary materials (lithium nickel cobalt manganese oxide/lithium nickel cobalt aluminum oxide), and lithium titanate—as well as sodium‑ion batteries. 10. Scan‑code activation for convenient operation and traceability.

I. Technical Features
1. Single-point independence: independent charge and discharge settings can be configured for each channel, offering flexibility and convenience.
2. Channel isolation: Each channel is electrically isolated from the others and shares no common ground; individual cells within the battery pack can be charged and discharged independently or in series‑connected stacks.
3. The software is powerful and features a user-friendly human-machine interface.
4. Four-wire output interface with high accuracy.
5. Modular design for easy maintenance.
6. Energy regeneration: discharging energy back to the grid, promoting energy conservation and environmental protection.
7. Equipped with protection mechanisms against overvoltage, reverse polarity, overcurrent, short circuit, overheating, and cross‑connection (i.e., random串联 connections among individual cells in a battery pack).
8. Each channel can be configured for grouped equalization or independent equalization.
9. It can perform testing on the entire range of lithium‑ion batteries, including lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, ternary materials (lithium nickel‑cobalt‑manganese oxide/lithium nickel‑cobalt‑aluminum oxide), and lithium titanate, as well as sodium‑ion batteries.
10. Scan the code to start, making operation and traceability convenient.

Software
1. The software supports various resumption modes, including manual pause‑and‑resume, automatic resume upon software shutdown, resume after power loss, resume following a communication interruption, and resume after an abnormal stop.
2. Supports barcode scanning, enabling the reading of both 1D and 2D barcodes, with options such as sequential scanning, skip‑channel scanning, and tray‑based scanning.
3. Detailed test data is stored locally, allowing you to view current and historical data for each channel at any time. Data can be displayed either as tabular values or as corresponding curves, and you can export the data as Excel reports individually or in batches. Additionally, you can configure the system to automatically export the data upon test completion as needed.
4. Supports capacity grading, enabling battery grade classification.
5. Supports pass/fail judgment at the end of testing, determining Pass or NG results based on specified cycle capacity, voltage, time, and other parameters.
6. Supports various step‑by‑step protections as well as global protection against voltage, current, and temperature abnormalities, with corresponding fault alarms.
7. Supports unit conversion;
8. Supports backend storage on the database server or integration with the MES (optional);
9. Supports MES system creation (optional);
10. Offline software protection;
