Renewable Energy Storage Laboratory (RESL)

Dalhousie University, Halifax, Nova Scotia
What the facility does

Applied battery research of modules/packs including electrical, mechanical, thermal, safety, and control systems for performance assessment and model validation

Area(s) of Expertise

The facility houses a wide range of battery power cyclers, thermal chambers, and advanced data acquisition systems. We operate on cells, modules (~50 V) and battery packs up to 800 V and with 1000+ A over a range of temperatures from -70 to +325 °C. An outdoor containerized thermally conditioned test chamber has isolated test bays. Battery test samples are contained in tightly controls specialized environments to evaluate their energy, power, efficiency, and thermal performance over a wide range of conditions and control strategies. This includes long term degradation testing, advanced “stacked” control algorithms, and the use of predictive technologies.

Alongside the experimental laboratory is an advanced energy storage modeling center that creates powerful analytical models of battery systems for both short term and long term storage applications. These are applied at a range of scales including single applications and highly varied geospatial and temporal scales (up to provincial levels). Models are then validated with results from experiments.
