PCM briefing: Traction battery for electric vehicles; Ember mug available in Apple stores

Ben Welter - Friday, October 19, 2018

• The Fraunhofer Institute for Structural Durability and System Reliability in Darmstadt, Germany, has developed a traction battery that can use thermal energy as a heat source in electric vehicles. A new type of fiber-reinforced composite sandwich housing protects the battery from temperature fluctuations. The phase change material composite system is designed to precondition the battery at low outside temperatures and reduce heat generation during rapid charging. The system was developed as part of the European Union's Optimized Energy Management and Use project. "We've developed material, structural and process technologies that can guarantee drivers a more reliable and uniform range for their battery-powered vehicles," said Felix Weidmann, project manager at Fraunhofer LBF.

Airec AB of Sweden has joined the EU Horizon 2020 project SWS-Heating. The project's goal is to develop seasonal thermal storage of solar energy. The energy will be stored in phase change materials. Airec will develop heat exchangers for the project.

PCM briefing: UCF wins $360,000 grant to develop solar storage module; Nike unveils prototype cooling vest

Ben Welter - Monday, September 17, 2018

• The University of Central Florida was awarded a $360,000 grant from the National Science Foundation last month to develop and commercialize a grid-connected solar storage module. UCF is partnering with battery maker AllCell Technology to develop the system, known as iPV++. The system will use smart inverters and battery management to deliver stable and predictable PV-based solar power for grid-tied applications. AllCell phase change composite material will provide passive thermal management of the system's lithium-ion battery modules. Dr. Issa Batarseh, UCF electrical engineering professor and the project principal investigator, says use of the material "guarantees the safety of the battery modules, simplifies the installation and maintenance, and significantly increases lifetime due to temperature control.”
