Chassis Dynamometers

AWD-500-AC/EC Hybrid Series

12.625" Rolls, 150-mph, 3,000-hp, 900-hp Peak Absorption, 2WD or AWD Modes

AWD-500 AC/EC Hybrid Series

The AWD-500-AC/EC Hybrid Series Chassis Dynamometers were designed for pre-certification development and testing of both 2WD and AWD hybrid and electric vehicles with wheelbase ranges from 88-inches to 118-inches.

A mechanically-linked 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.

The AWD-500-AC/EC Series incorporates an AC drive motor and a powerful air-cooled eddy current power absorbtion unit to provide the perfect combination of precision and economy. Systems are available with AC Motors ranging from 100-hp up to 600-hp and with one or two air-cooled eddy current PAUs for extended testing to meet the needs of your application.

The AWD-500-AC/EC Series provides a cost-effective design and enables quick development cycles for performing intitial hybrid and electric vehicle calibrations, traction system motoring, regenerative braking and limited traction conditions using road load and federal drive cycles, electric power systems analysis, HEV/PHEV/EV controller development, efficency testing, fuel consumption testing, and other complete vehicle or sub systems simulations.
