Reliable Storage Units for Electromobility
Next to the cell chemistry of energy storage systems, the overall »Power Pack System« plays an important role for vehicle construction. The Fraunhofer IVI executes research in all fields of this sector, from cell packaging to battery and thermal management systems, aspects of housing construction as well as the integrated protective circuitry.
Operators in the emerging hybrid and electric vehicle market lack the option of assessing the disposability and state of their vehicles, most importantly that of the batteries. Sometimes, however, disposability is a crucial factor for success. The IVImon system determines relevant state parameters of the battery storage unit and provides them in a user-friendly way. With these features, IVImon provides the basis for a number of new business models.
Heat2Go
Emission-free heating of fully-electric vehicles is currently only possible with a significant reduction in range. In order to solve this problem, the Fraunhofer IVI developed a fast-charging latent heat storage system in the course of the Heat2Go project. The energy is thus no longer supplied by the traction batteries, but by wayside infrastructure. Battery buses that operate by the principle of opportunity charging are now able to absorb all the energy required for a cycle within a few minutes at the terminal stop and without straining the battery during heating mode.
