The project brief

The brief

WAE were selected to design, develop, manufacture, and supply the batteries and vehicle control modules (VCMs) for the first electric multi-brand Touring Car racing series, ETCR.

The work

Initial feasibility work to in vehicle testing was completed in just seven months. Extensive Computation Fluid Dynamics (CFD) and Finite Element Analysis (FEA) simulations were run in September 2019, allowing for manufacture in December culminating in physical testing to validate a full race season. The pack will also allow four “push-to-pass” events over the 21-minute race distance. CFD thermal analysis was performed at both cell and pack level to model in detail the thermal characteristics of the battery pack in order to optimise cooling and weight efficiency.

ETCR is the first ever multi-brand Touring Car series with production cars powered by a common 100% electric powertrain.

The outcome

798V battery pack provides a peak power of 500kW and 300kW continuous power with a 62kWh capacity

Can be recharged in less than an hour from 10% to 90% at 60kWh

Provides an electrical barrier against electromagnetic current and to survive a 50g crash simulation
