Cell to pack
Test individual battery cells, modules, and complete battery packs for in-depth characterization at each stage of development, ensuring quality and performance at every scale.
Regenerative power
Designed with regenerative capabilities, often exceeding 90% energy recovery, so energy from the battery during discharge cycles is fed back into the grid rather than being dissipated as heat.
Comprehensive software
Define, control, and monitor complex test sequences, including performance, functional, aging, and environmental tests with built-in compliance for global industry standards.
EIS across all channels
Support electrochemical impedance spectroscopy (EIS) on multiple channels to characterize a cell's impedance across a frequency range, helping identify potential issues or degradation mechanisms.

Frequently asked questions
EV battery testing, while crucial for the success of electric vehicles, presents a unique set of challenges due to the complex and high-energy nature of the technology. Overcoming these challenges often involves leveraging advanced simulation tools (like battery emulators), developing sophisticated test automation, investing in robust safety infrastructure, and fostering interdisciplinary expertise. Battery testing challenges span across technical, safety, logistical, and economic domains. These include the following:
- High voltages and safety risks: The inherent dangers of working with high-voltage batteries require strict safety measures and specialized equipment.
- Complexity of battery systems: Testing at cell, module, and pack levels, with various chemistries and complex BMS.
- Evolving technology: The rapid pace of battery development requires adaptable and future-proof testing solutions.
- Long testing durations: Cycle life testing and aging simulations can be time-consuming.
- Environmental conditions: Assessing performance under varying temperatures, humidity, and vibrations.
- Data management and analysis: Handling and interpreting large volumes of test data.
Keysight offers a comprehensive suite of EV battery test solutions designed to address the entire battery development lifecycle, from individual cells to complete battery packs and their accompanying Battery Management Systems (BMS). Keysight battery test solutions provide a holistic approach to battery validation, covering the entire spectrum from basic electrical characterization to complex system-level integration and safety testing, all supported by powerful software for automation and data management. Here's a breakdown of the types of tests Keysight EV battery test solutions can perform at the cell, module, and pack levels:
- Electrical characterization:
- Capacity and efficiency: Measuring the total energy a cell can store and how efficiently it can charge and discharge.
- Internal resistance (DCIR/ACIR) and impedance (EIS): Assessing the cell's internal resistance and impedance using methods like Electrochemical Impedance Spectroscopy (EIS) to understand its power density, heat dissipation, and State of Health (SoH). This is critical for identifying early signs of degradation or flaws.
- Voltage, current, power: Precise measurements of these parameters during various charge/discharge cycles.
- Capacity and efficiency: Measuring the total energy a cell can store and how efficiently it can charge and discharge.
- Cycle life and calendar life testing: Simulating repeated charging and discharging cycles and long-term storage to evaluate a cell's degradation over time and predict its lifespan.
- Thermal performance: Assessing how cells react to temperature changes and their thermal stability.
- Self-discharge analysis: Characterizing how quickly a cell loses charge when not in use, a key indicator of cell quality. Keysight emphasizes methods that reduce test time for this.
- Formation testing: Performing the initial charge/discharge cycles required to form the Solid Electrolyte Interphase (SEI) layer, which is crucial for cell performance and longevity.
- Real-world emulation: Simulating various real-world conditions (e.g., driving cycles, temperature profiles) to assess module performance.
- Connection quality: Detecting faulty connections between cells within a module or pack, which can lead to performance issues or safety hazards.
- High-power charge/discharge: Testing the entire battery pack's ability to handle high power levels for charging and discharging. Keysight solutions can handle power up to 300 kW and voltages up to 1500 V.
- Software testing: Keysight's solutions are further powered by their software, which allows for control, testing, and evaluation of the entire energy storage test environment, including automation of compliance, load, and endurance tests. They also offer Lab Operations for Battery Test software for optimized test lab management, enabling efficient planning, coordination, and data management across multiple test stations and locations.
