2.1 ABOUT THE 900 EX
The 900 EX is a bi-directional, computer-controlled, two-channel, DC power
processing system offering superior accuracy and flexibility. The system was
specifically designed for testing (i.e., “cycling”) electric and hybrid-electric vehicle
components and subsystems.
The 900 EX is an ideal test system for a wide range of DC loads, in addition
to batteries, offering more than a traditional power supply system. Examples
include Auxiliary Power Units (APU), flywheels, motors, inverters, batteries, fuel
cells, capacitors, and more. The 900 EX uses the bi-directional characteristic of
the electric utility (it can deliver and absorb power) to meet the needs of both
uni-directional and bi-directional operation.
Power is transferred from the utility to the load or from the load to the utility.
Using the utility to absorb power eliminates the need for external resistive loads
and conserves energy that is normally lost. In addition, the 900 EX incorporates
special power processing algorithms to perform a wide variety of tests.
2.2 900 EX POWER APPLICATIONS
The 900 EX is flexible and may be used for a variety of DC power applications
(see Table 1). This section describes a few typical applications to illustrate the
different features of the 900 EX.
