Pulse Simulation Test with Langtian System
In battery research and development, pulse charge and discharge processes are widely used to simulate real working conditions. We conducted a pulse simulation test to provide reliable data for evaluating battery performance.
The test was carried out in four steps: hibernate, discharge, hibernate, and charge. During the discharge and charge steps, pulse mode was applied with a current of 1mA, voltage ranging from 1000mV to 3600mV, and temperature maintained between -30°C and 30°C.
| Step | Mode | Current (mA) | Upper Voltage (mV) | Lower Voltage (mV) | Time | Max Temp (°C) | Min Temp (°C) |
|---|---|---|---|---|---|---|---|
| 1 | Hibernate | - | - | - | 00:00:05 | 30 | -30 |
| 2 | Discharge (Pulse) | 1 | 1000 | 3600 | 00:01:01 | 30 | -30 |
| 3 | Hibernate | - | - | - | 00:20:00 | 30 | -30 |
| 4 | Charge (Pulse) | 1 | 1000 | 3600 | 00:01:01 | 30 | -30 |
The graphs below show the battery’s response to pulse charge and discharge. The red curve represents voltage changes, and the green bars show current pulses. The data indicates stable battery behavior under the simulated pulse conditions, providing a clear picture of performance over time.
Pulse simulation tests are essential for evaluating battery performance under real-world conditions. This method helps engineers and researchers understand battery behavior more accurately and design better testing protocols.
