High-Performance 2E Hybrid Powertrain Engine Test Cell at Millbrook with engineers performing engine testing and hybrid powertrain testing

High-Performance 2E Hybrid Powertrain Test Cell

This test cell is ideally suited to testing high-performance high-speed engines and complex hybrid powertrain development testing.

It has two wheel-mounted, ultra-high dynamic AC dynamometers and a 300kW battery simulator. It is large, allowing for additional equipment to be added as required, and self-contained, including its own control room. The 40,000L fuel tank is split into two bulk volumes.
