Battery | Cell, Module, Pack Testing

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.

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.

Battery Simulation

Battery simulation software for testing battery-connected devices in all applications to confirm if the device under test in performing as intended. Battery state is simulated if the battery is unavailable for testing, which eliminates waiting for the charge/discharge of an actual battery. Real-time test results include voltage, current, power, SOC%, charge/discharge state, and capacity.

Fuel Cell Testing

Fuel cells produce power by combining hydrogen fuel and oxygen electro-chemically and are extremely efficient and environmentally friendly. Chroma’s battery test platforms are engineered and well-equipped to support fuel cell research and design validation for efficiency, power, and characteristics.

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.
