A New Standard for Battery Validation in Electric Mobility
Electric vehicle battery systems are becoming increasingly complex, with higher energy densities, tighter safety margins, and evolving performance expectations. Ensuring consistency across cells, modules, and battery packs requires precise, scalable, and highly reliable testing systems.
At Infiwave, we provide advanced EV battery testing solutions that enable manufacturers to detect micro-level variations, validate performance, and ensure safety across the entire battery lifecycle.
Addressing Modern EV Battery Testing Challenges
As battery technologies evolve, testing requirements must keep pace. Manufacturers today require systems that can:
- Detect minute electrical anomalies at the cell level
- Scale seamlessly from R&D to high-volume production
- Integrate with automated and complex test environments
- Deliver high accuracy, repeatability, and uptime
Even the smallest variation in voltage, resistance, or temperature can impact the performance and safety of the entire battery system.
Comprehensive EV Battery Test Solution
Battery Characterization & Electrical Measurement
Accurate electrical measurement forms the foundation of EV battery validation. Our capabilities include:
- Open Circuit Voltage (OCV) measurement for battery grading
- DC internal resistance and impedance testing
- Charge and discharge profiling under static and dynamic loads
- Self-discharge analysis and leakage detection
These measurements enable early identification of defective cells and ensure consistent pack performance.
Battery Cycling, Formation & Aging
Battery performance is defined over time. We simulate real-world operating conditions through:
- Formation and aging cycle testing
- High-precision charge/discharge cycling
- State of Charge (SoC) and State of Health (SoH) evaluation
Formation and cycling are critical stages that directly influence long-term battery and reliability.
Battery Pack & System-Level Testing
Testing at system level ensures the reliability of fully integrated battery packs:
- Full pack charge/discharge simulation
- Dynamic load response testing
- Battery management system (BMS) validation
- High-voltage and high-power performance testing
Advanced systems enable controlled energy flow, simulating real driving conditions and load variations.
Thermal & Environmental Testing
Battery safety and efficiency are highly temperature-dependent. Our testing includes:
- Multi-point temperature monitoring
- Thermal profiling under load conditions
- Environmental simulation (temperature, humidity, stress)
- Thermal runaway detection indicators
Temperature behaviour is a key indicator of battery health and potential failure risks.
Mechanical & Interconnection Testing
Reliable electrical connections are essential for safe battery operation:
- Weld integrity testing (tab and busbar connections)
- Low-resistance measurement for joint quality
- Detection of micro-ohmic variations
Poor connections can increase resistance, generate heat, and lead to critical failures
Insulation & Safety Testing
Ensuring electrical isolation and safety compliance is critical:
- Insulation resistance testing
- Short-circuit detection and analysis
- Overvoltage and fault condition simulation
Proper insulation prevents hazardous failures and ensures system reliability.
Battery Grading & Quality Control
Battery grading ensures that only high-performance cells are used in EV applications:
- OCV-based classification (Grade A, B, C)
- Detection of internal defects such as micro-shorts
- Performance-based sorting for EV and second-life use
Accurate grading improves pack consistency and lifecycle performance.
Scalable & Energy-Efficient Test Infrastructure
Modern EV battery testing demands flexible and efficient systems:
- Bidirectional power systems for charge and discharge
- Regenerative energy capabilities to return power to the grid
- Modular test setups for scaling from lab to production
- Automated data acquisition and control systems
Energy recovery systems can significantly reduce operational costs while improving sustainability.
