MD-AWD-150-SE-EV Overview

THE MAE-AWD-150-EV Designed for E-Mobility Testing

With the growing market of electric vehicle (EV, BEV, HEV, PHEV, FCEV) , Mustang has developed a series of rolling roads that are cost-effective, highly accurate, and designed for testing EVs with advanced testing road-load simulation capabilities.

• Mechanically-linked all-wheel-drive Design

• Efficiency Energy Loss Evaluation of EVs

• Precision Road-load Simulation

• kWh/mile Evaluation for EVs

• Battery Power Measurement (Optional)

• Longer wheelbase available

Why Rolling Roads

The MAE-AWD-150-EV series of rolling roads were designed for testing of both 2WD and AWD electric vehicles. AWD models with a mechanically-linked roll system are available to accommodate wheelbase ranges from as short as 89-inches all the way up to 127-inches without needing to adjust the rollers.

A mechanically-linked AWD roller system synchronizes the front and back roller speeds to simulate a flat, dry road condition. Synchronization, or linkage, insures that the front and rear rollers are always spinning at precisely the same road speed when in AWD Mode, thereby eliminating the possibility of activating a vehicle’s traction control system and insuring that a vehicle’s torque management system is operating under the assumption that the vehicle is not skidding, turning or slipping.

To achieve this, Mustang’s AWD-150 incorporates a linked drive system that synchronizes the front and back rollers to simulate a flat, dry road condition. Synchronization, or linkage, insures that the front and rear rollers are always spinning at precisely the same road speed. This process eliminates the possibility of activating a vehicle’s traction control system and also insures that a vehicle’s torque management system is operating under the assumption that the vehicle is not skidding, turning or slipping.
