SEEL – Energy Storage Testing

Research and testing environments supporting industrial development

SEEL’s battery research laboratory is built to meet industry needs for rapid iteration, high data quality and stable test conditions. It includes all equipment required to develop and verify new cell chemistries, materials and design concepts — from temperature chambers and cell cyclers to gloveboxes and fume hoods.

In addition to the research environment, we offer testing at cell, module and pack level with flexible equipment capable of handling different formats, chemistries and BMS solutions. All tests are performed in controlled environments to ensure reproducible, industry‑standard results.

Test capacity for cells, modules and complete battery packs

Battery cells

We test all commercial cell formats and offer scalable current levels, parallel channel configurations and direct liquid cooling to replicate real operating conditions. We also develop testing with pressure and strain measurement for more advanced analysis of battery performance and durability.

Battery modules

Our module chambers handle modules and smaller packs with support for BMS/MMS, CAN communication and SEEL’s own BMS when needed. The equipment is dimensioned to meet industrial requirements for voltage, current and power.

Battery packs

Our largest climate chamber accommodates complete battery packs including cooling systems, BMS and mechanical components. We offer parallel coupling for higher power levels and detailed measurement of cell and module parameters to support validation of full pack performance.

Charging testing for global markets

SEEL provides testing and verification of charging functions according to international standards such as CCS, CHAdeMO and GB/T. We support three key industrial use cases:

• EV charging performance
• Charger performance
• Communication and energy transfer analysis between vehicle and charger

Our test equipment can simulate electrical grids from different regions and is prepared for megawatt charging, fast‑charging and Vehicle‑to‑Grid (V2G), making it relevant for both current and future electric‑vehicle products.

Safe and energy‑efficient test infrastructure

SEEL’s facilities are built to meet industrial requirements for safety and operational reliability. We offer:

• High‑pressure water mist to counter thermal runaway
• Gas detectors and isolated rooms for incident management
• Noise‑free work environments through separate machine rooms

All test equipment is regenerative, meaning discharge energy is recovered and reused internally. Combined with rooftop solar panels, this reduces both operating costs and environmental impact while supporting sustainable battery testing.
