The research team has been testing batteries for more than a decade, in both portable and traction applications, with special dedication to Ni and Li technologies. Since its formation in 1997, focuses his research on the electrical characterization of batteries, and on the design of efficient fast-charging and management methods, with a simultaneous transference of results to companies.


In recent years, the experience is being applied to electrical and chemical characterization of the new Li-ion technologies, with emphasis on LFP batteries because of its applicability in the field of electric vehicles.

Research Areas

Laboratory Tests

  • Design of specific testing methodologies for each application.
  • Battery characterization under variable conditions of charging/discharging and room temperature.
  • Study of thermal behavior, including the use of an infrared camera.
  • Analysis of deformations (increase of volume and/or pressure) and gas expulsion detection.
  • Performance evaluation in specific applications and/or under extreme operating conditions.
  • Aging test (determination of cycle life).
  • Degradation study: evaluation of capacity lost, internal resistance increase, etc.

Analysis of Li-Ion Cells Degradation

  • Disassembled of cells and post-morten analysis with the collaboration of chemical research groups from the University of Oviedo and INCAR (CSIC).
  • Independent electrochemical tests of each material (graphite and nanophosphate) to assign degradation signals to each electrode.

Field Evaluation

  • «In situ» or remote battery monitoring in the applications.
  • «On board» data acquisition units to analyze the road performance of EVs.

Projects Development

  • Selection of the most suitable energy storage device for each application.
  • Implementation of automated testing systems for companies.
  • Development of charging methodologies, including fast charge.
  • Design of batteries monitoring and management systems (evaluation of protocols for BMS).
