Battery | Cell, Module, Pack Test

High precision, integrated battery test and energy storage test solutions designed for lithium ion and other battery chemistry. From R&D to end of line, we provide advanced battery test features including regenerative discharge systems that recycle energy sourced by the battery back to the channels in the system or to the grid. Systems are configurable and flexible with multiple channel capabilities that can be upgraded as testing requirements change.

Battery Test Solutions

Chroma satisfies battery test requirements such as charge rate, discharge rate, state of charge (SOC), and state of health (SOH), and depth of discharge (DoD) with your need for accuracy in measuring voltage, current, temperature and power – statically and dynamically.

Battery Cycling | Cell, Module, Pack

Battery cell, module and pack level charge/discharge cycle testing solutions designed to provide high accuracy measurement with advanced features. Most of our solutions are regenerative – so energy sourced by the battery back is recycled back to the channels in the system or to the grid. Systems are configurable and flexible with multiple channel capabilities that can be upgraded as testing requirements change. 

Battery Pack ATS

Chroma 8720

Test the battery packs in end of line (EOL) production for a comprehensive Pass/Fail check, including mechanism assembly, pressure insulation, BMS communication, internal high voltage relay parts, battery balance, and temperature distribution, etc.

Battery Reliability Test System

Chroma 17010

Chroma’s Battery & Reliability Test System is a high-precision system designed specifically for testing lithium-ion battery (LIB) cells, electric double-layer capacitors (EDLCs), and lithium-ion capacitors (LICs).

Ultra/Super Capacitor

Chroma offers ultra and super capacitor charge/discharge testing systems with high precision output and measurement up to 0.02%. Satisfy IEC 62391 EDLC test requirements with a high sampling rate of 10ms. The modularized multi-channel architecture offers both flexibility and expand-ability, catering to cycle test requirements. It is capable of supporting various charge/discharge test modes such as CV (Constant Voltage), CC (Constant Current) and CP (Constant Power). 

Fuel Cell Testing

Fuel cells produce power by combining hydrogen fuel and oxygen electro-chemically and are extremely efficient and environmentally friendly. With that said, fuel cell technology has yet to reach the mainstream and requires further development. Chroma’s battery test platforms are engineered and well-equipped to support fuel cell research and design validation for efficiency, power, and characteristics.

Battery Simulator

Chroma A170202

Validate device functions during development in lieu of an actual battery or batteries.

Battery Simulation

Battery simulation software for testing battery connected devices in all applications to confirm if the device under test in performing as intended. Integrated with our 17020, 17030, and 17040 bidirectional battery testers, battery state is simulated if the battery is not available for testing and eliminates waiting for the charge/discharge of an actual battery. Real time test results include voltage, current, power, SOC%, charge/discharge state and capacity.

Battery Safety Testing

Chroma offers several other new solutions for developing safe batteries. An example of this would be if battery cells are connected to a module with inadequate insulation, the battery cell or module may short due to insulation materials failure. Our electrical safety testers support AC/DC hipot, leakage current (LC), insulation resistance (IR), and partial discharge (PD) at very high speed and accuracy to ensure the quality and safety of cells and modules before they go to the next level of production.
