Application Profile Engineering Firm Uses LMS Imagine.Lab Amesim to Optimize Driving Range of Electric Vehicles Sebastian Brixner, System Engineer Continental Engineering Services Julie Ercolani-Peck, Marketing Manager Siemens PLM Software Attaining Energy Efficiency One of the major concerns about battery systems used in electric vehicles is that their performance and durability can be diminished by extreme temperatures. In cold temperatures, the need for cabin and battery heating and the increased rolling resistance of winter tires are the most adverse conditions for any electric vehicle. The key is to determine how to allocate battery energy to make the most energy-efficient use of the vehicle. On cold days, warming a battery gradually brings the system's temperature to a level that allows it to provide enough discharge power for expected vehicle performance. Like humans, a battery functions best at room temperature, and any deviations in temperature changes the battery performance and/or longevity. Battery heating systems and optimal thermal management are critical for effective operation in all climates. The objective is to deliver a battery pack at an optimum average temperature with even temperature distribution. The question is: how do you determine the best heating architecture? Continental Engineering Services focuses on E-Mobility development. Leveraging Expertise Since 2006, Continental Engineering Services (CES) has been active worldwide as an independently operating provider of comprehensive engineering services. The expertise of CES has LMS Amesim lets engineers to optimize complex mechatronic systems in record time at a reasonable cost. Here, the high-voltage positioned the company to work on projects such battery and the thermal and energy management strategies as vehicle architecture and powertrain analysis of are specified. electric automobiles. Original equipment manufacturers (OEMs) have turned to CES for electrified drivetrain performance studies, optimization of heating systems and build-up of electrified prototype vehicles and demonstrators. In the design phase, the layout of the high-voltage battery and the thermal and energy management strategies have to be specified. Despite space limitations, weight, complexity and cost limits, the requirements of driving range and performance have to be met. Finding the best possible solution takes numerous optimization loops, testing, experience and time, and that's where LMS Imagine.Lab Amesim software from Siemens PLM Software comes in. It enables engineers to optimize complex mechatronic systems at reasonable cost. 34 Battery Power * Spring 2015
