1-24 Series 50A Charge 120A Discharge BMS Testing Equipment
Products Description
The ACEY-BP24-50A120A is a 1–24S BMS tester designed for testing lithium battery protection boards used in battery pack manufacturing, R&D, and quality inspection.
The system simulates charging and discharging conditions to evaluate key BMS protection and recovery functions. It supports programmable test sequences for overcharge, overdischarge, overcurrent, short-circuit protection, balancing, self-consumption, internal resistance, and protection response time.
With support for up to 24 battery series connections and discharge testing up to 120A, the tester can be used for functional verification of BMS boards used in lithium-ion battery packs. The test process can be programmed and recorded, while test results can be exported for production traceability and quality control.
Applications
This 1–24S BMS testing system can be used for:
- Lithium battery pack manufacturers
- BMS manufacturers
- Battery pack R&D laboratories
- Battery quality inspection
- Production-line functional testing
- Electric vehicle battery pack development
- Energy storage battery system development
- E-bike and light electric vehicle battery applications
Product Advantages
1. 1–24S Flexible Testing
Supports BMS protection boards with different series configurations from 1S to 24S, making the system suitable for multiple lithium battery pack designs.
2. High-Current Protection Testing
Supports overcharge protection current testing up to 50A and overdischarge protection current testing up to 120A.
3. Programmable Test Sequences
Test procedures can be programmed for repeated protection and recovery tests, reducing repetitive manual operations during production inspection.
4. Test Data Traceability
Test records and abnormal events can be logged and exported to Excel for quality control and production traceability.
5. Balancing & Self-Consumption Testing
The system supports balancing voltage/current testing as well as single-cell and total BMS self-consumption measurements.
6. Suitable for R&D and Production
The equipment can be used for BMS development, sample verification, incoming inspection and production-line quality testing.
Test Functions
- Overcharge protection and recovery voltage testing
- Overdischarge protection and recovery testing
- Overcharge and overdischarge current protection testing
- Short-circuit protection response testing
- BMS balancing voltage and balancing current testing
- Single-cell and total self-consumption measurement
- Main-loop resistance testing
- Protection delay time measurement
- Programmable charge/discharge test sequences
- Test data logging and Excel export
A 1–24S BMS tester can evaluate whether a battery protection board responds correctly under different charging, discharging and fault conditions. Typical tests include:
| Test Item | Purpose |
| Overcharge Protection | Checks whether the BMS disconnects charging when cell voltage exceeds the set threshold |
| Overcharge Recovery | Verifies recovery after the overcharge condition is removed |
| Overdischarge Protection | Checks the BMS response when cell voltage falls below the protection threshold |
| Overcurrent Protection | Evaluates protection against excessive charging or discharging current |
| Short-Circuit Protection | Checks the response time of the protection board under a short-circuit condition |
| Balancing Test | Evaluates balancing voltage and balancing current |
| Self-Consumption | Measures the current consumed by the BMS |
| Internal Resistance | Measures resistance in the main loop |
| Protection Delay | Measures the response time of protection functions |
