EV-Lite Battery Project Aims to Cut Pack Cost in Half, Reduce Weight by One Third

EV-Lite, a 2-year project funded by the UK’s Technology Strategy Board, aims to revolutionize the electric vehicle industry by advancing battery technology.

Too Costly?  Addressing That is on EV-Lite's Agenda Too

Too Costly? Addressing That is on EV-Lite’s Agenda Too

The project, to be conducted in Coventry, England, is led by The Manufacturing Technology Centre and the consortium consists of Unipart Manufacturing, Electrovaya, RDVS, CRR, Loughborough University, Cenex and Bluebird Innovation Group.

The goals of the 2-year project are as follows:

Project Targets

  • Reduce weight of battery system components (excluding cells) by 30%
  • Reduce cost of battery system components (excluding cells) by 50%
  • No compromise on technical functionality
  • Simulation of assembly, fixtures, tooling, etc.
  • Bench testing using real world data and vibration, safety testing etc
  • End of life applications and scenarios to be considered
  • Based on 30,000 battery assemblies per annum

    Maya 300

A testing and production facility will be constructed within Coventry’s Manufacturing Technology Centre, at Ansty Park.  The facility will use the Maya 300 low-speed electric vehicle as it test bed.  The Maya features Electrovaya’s lithium-ion SuperPolymer battery.

EV-Lite believes that today’s batteries are over-engineer, which in turn drives up costs.  The project hopes to address this issue so that finished electric vehicles can sell at a lower price point.

Reducing costs in the main objective here, but EV-Lite believes weight is an issue, too.  Perhaps that’s why they called themselves “Lite,” as in lightweight?  Or light on the environmental impact?

    I’d say they are trying to advance battery “pack” technology, since they aren’t touching the cells. Interesting objective.

      They just want to draw grant, read it between lines. Battery chemistry is too difficult!

  2. Bret says:

    OK, sounds great. How exactly do they plan to do it? Current EV batteries may be over-engineered, but nobody wants them to catch on fire or lose capacity, like a LEAF in Arizona. The real breakthrough is increasing energy density within the cell, so there are fewer cells per KWh. Reducing the cell packaging won’t reduce the weight and cost significantly.

    I never really understood why Lithium Polymer didn’t take off for cars. I use them in my model airplane, where they are light, powerful and cheap.
