MAE’s latest product for the development, calibration, certification, End-Of-line and
repair & maintenance testing of electric and hybrid vehicles is the MAE-AC-4000 Series
Universal Automotive Test Stand. This new universal tester is an advanced independent-wheel-control
AC motor dynamometer and ABS brake tester that is capable of reproducing an unlimited
array of testing and simulation conditions for full product life cycle testing of electric
and hybrid vehicles and vehicle sub-systems. For vehicle development, calibration and certification
applications, the AC-4000 Series provides a cost-effective design and enables quick
development cycles for performing many functions. Perform initial hybrid and electric vehicle
calibrations, traction system motoring and ABS testing with skid simulation, regenerative
braking and limited traction condition simulations using road load and federal drive cycles,
electrical power systems analysis, HEV/PHEV/EV controller development, efficiency testing,
fuel consumption testing, repair & maintenance and other complete vehicle or sub systems
evaluations. MAE offers a number of lab-grade software and data acquisition packages for
Hardware-in-the-loop and R&D environments.The AC-4000 utilizes four independent AC motors,
one coupled to each set of rollers, to control the load to each wheel independently. A moveable
wheelbase system allows the AC-4000 to accommodate both 2WD and AWD vehicles with wheelbases
ranging from 90-140”. An automatic vehicle restraint and safety system greatly reduces
the test cycle time and ensures that vehicles remain safely in position on the tester. As
a EOL test stand, the MAE-AC-4000 Series offers a flexible solution for test control, data
acquisition and operator interface, stepping test operators through each step of an automated
EOL test sequence in a simple and user-friendly format, while collecting, analyzing and reporting
on vehicle systems status and performance data. MAE’s AC-4000 test stand communicates
with each vehicle via CAN communication to determine pass/fail results and to establish
certain vehicle systems statuses as required during the test procedure. The flexibility
of MAE’s systems allows us to easily adapt to meet unlimited test procedures and simulation
requirements. MAE’s experience and expertise with sophisticated End of Line systems stems
from having supplied a host of fully-integrated automated testing solutions for a wide range
of EOL testing applications. MAE offers completely customized end of line testing solutions for
your specific end of line testing applications.
