acumuladores

The research focus at the accumulator laboratory is the technological development of cells and lithium-ion, balteries for the inclusion of renewable energies and for empowerinig electric vehicles. Studies are also carried out on lead-acid batteries, an alternative that is valid for microstrip applications.

Its research areas are: real-time diagnosis of the state of charge and health of cells, modeling and electro-thermal simulation of cells and packs under different operating conditions, development of packs for applications in electromobility, and optimization strategies for improving the design of the packs.

This laboratory is part of the Energy Center and the Lithium Innovation Center.

The laboratory has a programmable load of 300W to perform cell discharges; equipment that allows tests of load/discharge with a capacity of 4KW; to be carried out an experimental device for testing at controlled ambient temperatures; a special welding machine for cylindrical lithium-ion cells; an 8-core workstation, and ANSYS professional license and modeFrontier that allow the electro-thermal simulation of battery packs and optimization of designs. In addition, it has instruments for the measurement and acquisition of electrical and thermal variables.

  • Optimal lithium battery packing (OLiBP/EOBLi): The objective is to develop software that helps in the process of designing battery packs taking into account the particular operation to which they will be subjected.
  • Health and Load State Estimation (SOHC): the objective is to develop a device capable of predicting the state-of-charge and health of a lithium-ion battery bank based on the historical usage pattern and Bayesian prediction algorithms.
  • Development of a lithium-ion battery pack for electric bicycles: the objective is to design, build, and test a battery pack that is part of a kit that allows the transformation of a traditional bicycle into an electric bicycle in only a few minutes.
  • Development of an SoC estimator for a lead-acid battery bank: the objective is to develop a fuzzy logic based model that allows the online SoC estimation of a pack that is installed in the Huatacondo microgrid.
  • Development of a cell packaging validation device: the objective is to design and build equipment that allows validating designs in terms of the performance of the ventilation system.
