6V 125A 8CHS Regenerative Battery Charge Discharge Tester for Li-Ion/Lead-acid/Ni-Cd/NiMH Battery
Product Description
ACEY-HRCDS-6V125A-8CH energy-feedback lithium ion cell tester is used for cycle life tests and quality control in the production or experimentation of various battery types, including lithium-ion, lead-acid, nickel-cadmium, and nickel-metal hydride batteries.
It conducts comprehensive tests such as battery cycle life, capacity, charging and discharging characteristics, charge retention capacity, charging and discharging efficiency, as well as tolerance tests for overcharging and over-discharging rates.
Working Environment
- Power supply of the whole cabinet: AC 380V±10%, frequency: 50HZ±5%.
- Maximum input power of the whole cabinet: 8 KW (8CH)
- Working temperature: 0℃-45℃.
- Ambient humidity: not more than 85% R.H (no water vapor condensation).
- Environment without strong vibration, no corrosive gas and flammable and explosive gas.
Product Features
- Current support multi-range: 0.02A-25A (accuracy ≤ 0.03%FS), 25A-60A (accuracy ≤ 0.03%FS), 60A-125A (accuracy ≤ 0.03%FS).
- Minimum discharge voltage**: -6V.
- High reliability, low noise, and high energy density**, making it flexible for laboratory use.
- Energy feedback (optimal grid efficiency of 70%)**: Energy feedback type, both charging and discharging are energy-efficient, saving significant electricity costs and reducing air conditioning expenses caused by heat dissipation.
- Fixture contact impedance monitoring**: Prevents safety issues caused by poor terminal contact or oxidation over time.
- CCCV charging**: Seamless transition during the charging process without any voltage or current surges, effectively preventing heat concentration due to peak currents, which could lead to electrode powder shedding, micro-shorts, islanding effects, or overcharging, triggering PCB protection mechanisms.
- Stable and high-precision current and voltage sampling**: Utilizes high-precision, high dynamic range ADC/DAC units, ensuring high voltage sampling accuracy and long-term stability.
- DL dynamic load protection function**: Effectively protects batteries during charging and discharging, preventing sparks and avoiding current surges caused by loose connectors, thereby safeguarding battery components such as MOSFETs and fuses.
- Voltage clamping function**: During charging, clamps the voltage to a safe level in case of battery protection activation or equipment abnormalities, preventing damage to the battery or battery protection board.
- ECD & EVD protection**: Avoids and identifies batteries that activate protection under unqualified conditions, stopping charging or discharging prematurely.
- Rich software features**: Includes "working condition simulation testing" and "charge-discharge testing," paired with a professional data analysis software platform, enabling rapid data analysis during R&D testing. Working condition simulation testing supports the import of condition files (Excel format, time-current, or time-power modes) for millisecond-level test verification.
- Third-party device control support**: Controls devices such as environmental chambers during testing, with related test data saved together to meet battery testing requirements (optional, third-party protocols required).
- Capacity calibration function**: Designates a specific step's discharge capacity as a benchmark for current and capacity judgment conditions in various cycle tests.
- RSOC capacity recharge testing support**: Uses the charge/discharge capacity from the previous cycle (or cumulative capacity from earlier steps) as a benchmark for setting capacity judgment conditions in the next step.
- Cumulative capacity SOC function (AH calculator)**: Calculates real-time cumulative capacity based on preset cell capacity, serving as a step judgment condition.
- Single-channel automatic Excel export**: Defines relevant time nodes/export paths to automatically generate Excel files for the corresponding channel.
- Data statistics function**: Includes online and historical data statistics.
