Energy Storage System (ESS) Testing Solutions

Energy storage systems are becoming more powerful and more connected, which naturally makes them harder to validate with conventional test equipment. In high‑power ESS environments, manufacturers must monitor voltage, current, temperature, power, and communication signals at the same time, while verifying how the system behaves under real charge and discharge conditions.

This challenge goes far beyond battery testing. Full ESS validation requires visibility into pack behavior, control logic, CAN communication, anomaly detection, and power quality on both the DC and AC sides. Critical events—such as current spikes—must be detected in real time, with automated safety responses that protect both the equipment and the test environment.

Averna addresses these challenges. Designed for large‑scale, high‑power applications, our systems combine cyclers, CAN monitoring, safety logic, data acquisition, MES connectivity, and grid‑facing measurements within a single scalable architecture. The result is a reliable test environment that supports production and system‑level ESS validation with the traceability and control required by modern energy programs.

Averna’s ESS platforms combine automated test execution, real-time supervision, and complete system-level data visibility to meet the demands of high-power applications from validation through production.

Electrical, Thermal, & Power Monitoring

Our systems continuously monitor voltage, current, temperature, and power throughout the test process to give teams a clear view of ESS behavior under real operating conditions. This includes charge and discharge profile tracking, performance verification, as well as the detection of abnormal variations that could affect system stability or safety.

CAN Bus Monitoring & Control-Level Visibility

In complex ESS environments, electrical behavior must be understood alongside communication behavior. Averna integrates CAN bus monitoring directly into the platform to validate control logic and correlate communication signals with system performance during test execution. Alternative communication protocols are also available, such as MQTT or Modbus.

Critical Event Simulation & Safety Response

Averna platforms support the simulation and monitoring of critical events and anomalies to validate how the ESS reacts under abnormal conditions. Abnormal temperature rises, current spikes, and power peaks can be detected in real time, with automated shutdown logic and protective actions configured to secure both the equipment and the test environment.

24/7 Monitoring & ESS Performance Tracking

For programs that require continuous operation, our solutions support 24/7 supervision with live visibility into system status and safety conditions. Teams can track battery performance and thermal behavior, making it easier to supervise long-duration testing in production environments.

Power Quality Measurement & Grid Integration

We also support advanced capabilities on the grid-facing side of the ESS. Our platforms can measure and monitor power quality to and from the grid on both the DC and AC sides, support fast PMU data for WAMS and TSO applications, and provide full Power Quality Class A measurement for standard parameters according to IEC 61000-4-30 Ed.3.

These capabilities help manufacturers validate grid interaction and prepare for integration into broader energy management infrastructures.

Data Capture, MES Connectivity, & Battery Passport Traceability

ESS testing requires more than a simple pass/fail result. Averna platforms capture detailed data throughout the test cycle, with support for local storage, automatic MES transfer, and reporting workflows adapted to production needs.

The system can also support detailed Battery Passport information, helping manufacturers strengthen traceability across battery packs and complete ESS platforms.

Scalable Test Architectures for High-Power ESS Programs

Large-scale ESS programs often exceed the limits of standard off-the-shelf equipment. Averna develops scalable test architectures designed around the required power level, channel count, communication needs, and deployment strategy of each application.

This makes it possible to support high-power ESS validation and production with a platform that can evolve across volumes and global sites without starting from scratch.
