OSTLER Summary of Progress in Period 1


In general, the project is on schedule, with resource usage in line with expectations. WP2 Requirements for integrated storage, was completed on time, WP3 Crashworthy battery pack and vehicle crash investigation, is well underway, WP4 System integration, started on schedule and is well underway, WP5 Removable packs, started on schedule and is well underway, WP6 Demonstrators, started on schedule and is underway, WP7 Dissemination and exploitation, started on schedule and is making satisfactory progress.

Specific achievements in period 1 include:

  • Reviewed of current scenarios and forecasts for market penetration of EVs
  • Reviewed existing and planned regulations/standards e.g. ISO/TC22/SC21, ECE Reg. 100
  • Documented the underlying assumptions with respect to future development in regulations and standards
  • Identified the future requirements, targets and attributes for integrated storage systems;
  • Created a CAE model of a passenger car
  • Used CAE simulation to produce a deformation pattern based on 4126 numerical weighted vehicle collisions to help with the battery location study
  • Created a system specification document that encompasses a wide segment of the market including quadricycle, mini, compact and premium car types
  • Made significant progress in defining the OSTLER electrical architecture
  • Developed and agree the concept for a removable battery pack
  • Selected a donor vehicle and electric motor for the demonstrator
  • Created for review, a specification for the demonstrator vehicle
  • Created a project website: http://www.ostlerproject.com.  Access to public deliverables will be possible by following the appropriate link
  • Produced a project brochure.

It was concluded that the Regulations adopted in Europe, and in the rest of the World, with the exception of North America, are in general compliant with the UNECE Regulations that are intended to globally cover electric vehicle production. The USA adopts its own regulations, FMVSS, which are in general different to UNECE.  In order to try to aid electric vehicle market penetration, an effort to unify standards and regulations is required.  Different legislations and standards are an obstacle to car makers and can result in car manufacturers abandoning some relatively promising markets for the sake of stringent directives.
One objective of the OSTLER project is to develop a new removable battery pack module that is connected to the main battery pack installed in the vehicle.  The purpose of these removable modules is to easily extend the vehicle range (i.e. 5 km for each module added).  The removable battery pack should consist of relatively low weight, small modules, to enable them to be added and removed from the car by the user without significant effort or difficulty. The modules should be readily available (i.e. from service stations); the driver must be able to remove and replace them, and might pay only for its use and return it when discharged. The removable modules might be recharged in the service station.  The location of the battery packs within the electric vehicle will be considered in the project.  Although the final location of the battery packs will depend on many factors, from structural resistance of the car, to crash impact results, and accessibility to the removable modules, a basic distribution has been proposed in period 1.  In addition, with consideration of a variety of safety regulations, the following characteristics have been proposed for the removable modules: module nominal voltage: < 60V; maximum weight: 10 kg; desirable energy capacity: 1.4 kWh. These target values would enable an increase in vehicle range of approximately 5 km. although the exact range is dependent on a number of factors.
