Ensuring precision and quality is critical for manufacturers of lithium-ion batteries. One essential method for testing battery performance is charge/discharge cycle testing, which evaluates battery capacity and longevity under different conditions.
Battery performance testing is vital to determine the length of time a battery can be used before it deteriorates. The testing process involves repeatedly charging and discharging the battery to evaluate its capacity and performance and provide the essential data to predict its life expectancy.
Since current and temperature conditions significantly impact these cycles, monitoring these parameters is crucial for accurate assessment. Manufacturers can ensure higher product quality and reliability by understanding how various factors influence battery performance.
AstroNova, a leader in data acquisition and recording for 55 years, has integrated a thoroughly efficient and reliable solution for thorough battery charge/discharge cycle testing consisting of the following components:
- Sistema de adquisición de datos AstroNova Daxus® DXS-100: The core system for capturing data during testing.
- UNIV-4 Universal or IHVM-4 High Voltage Input Modules: Modules for handling different input types.
- ADP-T Thermocouple Adaptor: For temperature monitoring.
- Shunt Resistor: Used for precise current measurement.
The Daxus DXS-100 system captures crucial data during battery charge/discharge cycles, monitoring voltage and current load through a shunt resistor. Additionally, a derived channel integrates the current to provide real-time numerical displays of battery charge/discharge levels. The data can be monitored in real-time and saved to the internal hard drive for later analysis.
Temperature sensors can also be integrated into the system to monitor the thermal effects on battery performance. Engineers can determine how temperature fluctuations affect battery capacity and charge time by analyzing temperature data.
The Daxus system is easily scalable, allowing for the simultaneous monitoring of multiple batteries, providing channel-to-channel isolation, and enabling testing of batteries up to 1000VDC. Digital I/O channels further enhance the system’s capabilities by integrating it into automated test stands for long-term cycle testing.
The AstroNova Daxus DXS-100 system, with its versatile components and real-time data capture capabilities, is an ideal solution for measuring lithium-ion battery performance. By enabling detailed analysis of charge/discharge cycles and temperature effects, this system helps engineers optimize battery design and ensure higher quality and reliability.
