Hutchinson webinar: Engineered materials a reliable answer to EV battery thermal sensitivity
Thermal conditioning is necessary to keep the battery operational in a wide range of weather conditions and the way it is implemented impacts the resulting driving range, performance and lifetime.
Poor thermal insulation and poor temperature control of the battery and its enclosure can reduce dramatically the driving range. In our laboratory, we aim at imagining, designing, simulating and making systems based on the association of proprietary materials, super insulator and formulated phase change materials which have ability to maintain the lithium-ion cells, modules and pack in the best conditions.
Making a battery compartment insensitive to outside temperatures during parking phases is a simple way to restore the user of an electric vehicle, a significant energy capacity. Testing and demonstration show that a full pack insulation does not require higher performance liquid cooling and/or bigger heat pump. Dimensioning out from a sensitivity analysis to maximize the benefits for average journeys (usual cases) shows positive effects greater than the consequence of increasing weight.
