Societies around the world are looking for clean and affordable mobility. The global trend for sustainability is obvious, and electro-mobility is moving forward, driven by a significant progress with attractive market oriented cars with enhanced drive dynamics, cruising capabilities and driving range.

However, car buyers are still reluctant to purchase electrical vehicles (EV) that are still more expensive than conventional vehicles. Additionally, customers have concerns about limited driving range and doubts to reach the planned destination due to variations of up to 50% from the car’s nominal range. This underlines the need for improved autonomy and predictable mileage, powertrain and battery thermal endurance, and passenger comfort despite changing climatic conditions. Simply increasing the battery capacity is not a viable option for cost-efficient vehicles.

The expectation on the 3rd and 4th Generation of electrified cars is to have the same level of comfort as on conventional cars today. According to market intelligence safe, eco and human oriented mobility at afford-able costs is required. OSEM-EV translates the foreseen project innovations into a customer value proposition. Highest priority is improved mileage and predictable range without adding further cost and weight.

Review Preparation Meeting @ Hutchinson, Montargis, FR.

 

In May 2018, the OSEM-EV Review Preparation Meeting was hosted by Partner Organisation Hutchinson in Châlette-sur-Loing, held at the inspirational and collaborative Areas of 507 Fab House, close to the Hutchinson Research Center.

WP1 Requirements

Range limitation, due to the limited storage capacity of batteries, is one major issue in electric vehicles. The main challenge in this project is to achieve a systematic energy management of the vehicle, based on the integration of new electro-thermal energy management strategies and new subsystems, and focusing on solutions for solving the state-of-the-art major issues in electric vehicles. The energy consumption of the auxiliaries (e.g. climate control) and accessories, using part of the electric energy from the battery, are still worsening the global picture. In extreme conditions, up to 50% of the batteries’ capacity is absorbed by these subsystems. The systematic management of energy in electric vehicles is a mean to gain extended range without sacrificing comfort. The challenge is therefore to extend the range of electric vehicles in almost all climatic conditions. In this work package, the requirements of the concepts and solutions intended to be developed for the key subsystems in electric vehicles are specified.

Work Package 1 is led by DAIMLER AG.

Main objective of OSEM-EV is a comprehensive thermal management system by novel electro-thermal architectures and control algorithms, including thermal insulation, thermal storage, innovative heating and cooling approaches applied to the powertrain (battery, inverter and motor), battery life duration enhancement as a side effect of thermal management, electronic control of energy and power flows, energy efficiency of electrified accessories as well as energy substitution and harvesting functions.
