EASYBAT is part of the first EU Commission supported project for electric vehicles (EVs) with switchable batteries. Standardised automobile components and interfaces are developed within the framework of this project. This enables European automobile and battery manufacturers to easily integrate battery switching technology into their EV platform. Part of the Seventh EU Framework Program (FP7), EASYBAT is a 2.5 year project, which is co-funded by the European Commission.

Overall Project

The EASYBAT solution consists of mechanical, thermal, electrical and communication interfaces for switching a battery in and out of an EV quickly and safely. The solution in form of a demonstrator is integrated in an existing battery switch station in Paris and tested on EVs with battery switch technology to ensure it meets production-grade manufacturing criteria and European safety standards.

Role of TUM

The Institute for Energy Economy and Application Technology (IfE) at TUM is responsible for simulating battery switch stations in a predominantly renewable European power system. Hereby implications of battery switch stations are analysed on renewable energy integration, thermal power demand, primary energy charging costs as well as CO2 emissions. This involves the development of EV load demand and energy system modelling tools to simulate future developments thereof, ranging from 2015 to 2050 in 27 European countries. Hereby EVs with three different “range extension technologies” are assessed and compared to each other:

  • EVs with fast charge technology
  • EVs with battery switch technology
  • EVs with an additional micro internal combustion engine (existing benchmark EV, not shown in the diagram)

Result analysis

TUM’s Technical Report, titled “Analysis of the Renewable Energy Grid Integration Potential by Range Extension Technologies of EVs in Europe” by Gohla-Neudecker and Hamacher forms part of the project's work package 2 deliverables.
