Fleximod
The FlexiMod project set out to develop a new battery module and battery management system (BMS) as part of the retrofit conversion of a TX4 Hackney Cab to electric propulsion.
Project Overview:
The battery module is based on the common 2170 cylindrical cell format, and is designed to be available at a competitive price, even in low quantities for smaller volume manufacturers and projects.
Technology Developed
Project partner AMTE Power supplied its latest 2170 battery cells, which were built into the FlexiMod module by MEP Technologies, who also developed the BMS with DC charging capability. The module has also been designed to be chemistry and manufacturer agnostic, and allowing it to support multiple different voltage configurations depending on the project requirements, whilst utilising common auxiliary components like busbars and liquid cooling plates.
Project lead Electron Garage procured a TX4 vehicle and designed a retrofit electric drive solution for the taxi based on the FlexiMod battery box, without the need for any significant vehicle structural modifications.
Significant project outcomes
The cells produced by AMTE were one of the first commercial cells produced using the UKBIC facilities. A fully running TX4 EV has now been produced and tested by the consortium.
Commercial Opportunities
By creating a fully reversible TX4 electric retrofit which can be performed without having to physically alter the chassis, Electron Garage has developed an IVA compatible solution to enable the extended life of the donor TX4 vehicles with zero emissions. MEP Technologies also plans to discuss supply of BMS components and FlexiMod modules with resellers who supply the growing UK conversion market.
Importance of NVN funding
The significant strides in development made through this project could not have been achieved in such a rapid way without the significant support of the Niche Vehicle Network. The network also supports the market adoption of these technologies through connecting OEMs and technology developers across the network and supporting awareness at a national level.
