Batteries and Battery Packs

The development of high performance battery modules, packs and cells continues to be a priority for the next

generation of low carbon vehicles. To this end we have developed a suite of tools for appraising and designing new

battery systems and related hardware, greatly reducing R&D lead times.

 
Achievements include:
  • Innovative design concepts for battery modules and battery packs
  • New testing methodologies for appraising battery cells and modules
  • A comprehensive database of commercially available battery products
  • An integrated computer simulation model with the capability to predict battery performance characterist
    in a wide range of vehicle applications
  • A new library of finite element models enabling structural and safety analysis of battery modules and battery packs
  • A validated lower-cost Battery Management System (BMS) concept utilising new algorithms for energy
    balancing and new hardware
  • Guidelines to improve design-for-assembly aspects of battery modules
  • Guidelines for the recycling of battery products to reduce their overall carbon footprint
  • An advanced battery cycler capable of replicating harsh operating environments

 

Business Impact – New Products and Processes

 

Tata Motors European Technical Centre (TMETC) has developed a flexible, scalable module suitable to produce battery packs for each of the target Generic Technology Validator (GTV) platforms. This module has been fully validated during the programme and design iterations have been established.

Based on a reduced electrochemical approach, TMETC has also developed a brand new process to model the heat generated from batteries for any drive cycle using estimated voltage. This has been validated for a tested load cycle, and is being utilised by TMETC in the design of state of the art BMS and predictive vehicle drive cycle models.

Ricardo has developed new analysis techniques for determining the physical strength of battery modules and their components in resisting both normal and abuse case loads. These new techniques will be an important addition to Ricardo’s engineering services portfolio.

Given the extensive range of battery cell technologies and suppliers, one of the key challenges facing the industrial partners is selection of the most suitable cells for their specific applications. To support this, WMG has built a new state of the art lithium ion battery testing facility allowing performance and characterisation testing of a variety of battery cell technologies.
