More range for electric vehicles

Functionalized thermoplastic sandwich components within minutes

Press release / 14.2.2019

In times of impending bans for diesel and generally internal combustion engine (ICE) vehicles, battery electric vehicles (BEVs) are becoming increasingly interesting for buyers, especially in urban environments. Boosting battery capacities enable longer travels, however driving range of EVs varies especially at low ambient temperatures. Within the EU project “OPTEMUS” (Optimized Energy Management and Use), a large number of efficiency-enhancing technologies were therefore developed and holistically linked, in particular to reduce the range variation of a Fiat 500e EV. This includes a traction battery with thermal storage capacity, which the Fraunhofer Institute for Structural Durability and System Reliability LBF has developed with partners. The focus is on a novel sandwich battery housing made of continuous fibre reinforced thermoplastics (CFRTP), which helps to insulate stored heat in the traction battery for preconditioning. Fraunhofer LBF will present its research results from 12 to 14 March 2019 at the JEC trade fair in Paris at the Hessen joint exhibition in Hall 5, booth G71.
