1.0 Introduction
1.1 Overview
The ABC-170 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. Examples are auxiliary power units, flywheels, motors, inverters, batteries,
fuel cells, capacitors, and more. The capabilities are:
•Greater Accuracy / Finer Control
•Remote Voltage Sense Capability
•Independent Hardware Channel Enable
•Independent Mode Control for each Channel
The ABC-170 is an ideal test system for a wide range of DC loads other than batteries,
offering more capability than a traditional power supply system. The ABC-170 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 loads (as used in this manual, load
refers to a device or system connected to the ABC-170 for the purpose of receiving
and/or delivering DC power).
Power is transferred from the utility to the load, or vice-versa. Using the utility to absorb
power eliminates the need for external resistive loads and conserves energy normally
lost. In addition, the ABC-170 incorporates special power processing algorithms,
enabling the user to perform a wide variety of testing.

1.3 ABC-170 Applications
The ABC-170 is flexible and may be used for a wide variety of DC power applications.
This section describes a few typical applications to illustrate the different features of the
ABC-170.

ABC-170 Installation, Operation & Maintenance
11780-03-E Page 10 of 52 Webasto Charging Systems, Inc.
Constant Voltage Source
In Voltage Mode, the ABC-170 regulates the voltage of a given DC output channel. The
load may draw current from the ABC-170 at the regulated voltage and the voltage level
may be varied on demand, as with a conventional DC power supply. In addition, the
ABC-170 allows the user to define voltage, current, and power limits to protect the load
and maintain safe operating conditions.
The ABC-170 also allows for bi-directional power flow (i.e., it allows the load to
discharge current back to the utility), unlike standard power supplies. However, during a
blackout, ABC-170 shuts down operation automatically.
Constant Current Source
In Current Mode, the ABC-170 regulates the current of a given DC output channel. As in
constant Voltage Mode, the load may draw or provide current bi-directionally subject to
user-defined limits.
Battery Quick Charging
Battery charging algorithms vary considerably depending on many factors. A basic
quick charging algorithm involves charging the battery at a constant current rate (i.e., the
maximum charge rate) until a certain voltage level is reached and then maintaining that
voltage level while the charge rate decreases to a trickle charge. This can be
accomplished very simply with the ABC-170.
By setting the correct upper voltage limit and operating the system in constant Current
Mode, the user can assure that the ABC-170 will charge the battery at the desired
current until its voltage rises to the limit and will then maintain that voltage. No manual
adjustment is needed during the test.
More complicated battery charge algorithms can be achieved by modifying the operating
limits, modes and command values as the test proceeds. Such algorithms can be
implemented manually or they can be programmed and run automatically using the
ABC-170 Remote Operation System.
Battery Pack Cycling
Battery packs used in electric vehicles (EV) endure constantly changing demands. As
the vehicle accelerates and brakes, the battery may go from rapid discharge to charge
and back again in a matter of seconds. In addition, the daily driving and charging of an
electric vehicle puts the battery through a large number of deep discharge cycles,
resulting in shortened battery life.
Because of these factors, EV battery pack testing is highly important but also very
difficult. Simulating the demands of an electric vehicle on a battery pack requires
computer controlled testing with a highly accurate and responsive battery cycling
system.
The ABC-170 was designed specifically to handle the demands of EV battery pack
cycling. Using the ABC-170 Remote Operation System, USABC compliant tests can be
developed and run to verify battery pack adherence to requirements. Repetitive use of
these automated compliant test profiles can be used for comparative research as well as
production level testing.
Battery Emulation

ABC-170 Installation, Operation & Maintenance
11780-03-E Page 11 of 52 Webasto Charging Systems, Inc.
With its computer control capabilities, the ABC-170 can be programmed to emulate a
battery. The ABC-170 would first be put into constant Voltage Mode at the desired state
of charge. As current is drawn from the ABC-170, the voltage would be lowered as if the
“battery” were being discharged.
Similarly, as the “battery” is charged, the voltage would be increased. The algorithm to
determine how voltage changes in response to charging and discharging would be
determined by the user, based on the size and type of battery to be emulated, and then
programmed into the ABC-170 Remote Operation System.
Other Applications
As the above examples illustrated, the ABC-170 is very flexible and versatile so it can be
used for many other applications. Test or emulation of most DC power system can be
achieved with the powerful, computer controlled testing capabilities.
The ABC-170 may be valuable even for very simple application such as discharging
batteries and putting their power back onto the utility grid. With a basic understanding of
the system, users can employ the ABC-170 in a virtually limitless set of applications.
The ABC-170 base unit can be customized for particular applications using ROS Scripts
or Optional J1850 or CAN Communication capabilities. Contact Webasto customer
service for more information.

2.0 System Description
2.1 System Block Diagram
The ABC-170 architecture is shown in the following system block diagram (Figure 1).
The AC Inverter connects to the utility via an internally installed isolation transformer.
The DC Converter and AC Inverter transfer power via an Intermediate DC Bus and
communicate via an RS-485 data bus. The DC Converter also communicates to the
ABC-170 Remote Operation (ROS) System via an RS-232 data link, or CAN data link
depending on system configuration. The DC Converter provides the DC interface to a
load (or possibly two separate loads) in one of two configurations.

2.1.1 AC Inverter Functions & Controls
The AC Inverter regulates the Intermediate DC Bus based on the maximum voltage
expected by the DC Converter connected. The range for the Intermediate DC Bus is
350 - 425 Volts DC for 125KW source and 170KW sink. The bus can be raised to 450
Volts DC for 40KW source and 40KW sink operation.
Circuitry designed into the AC Inverter monitors the utility to detect any abnormalities.
This is accomplished by measuring the frequency and amplitude of the utility and
verifying that it remains within the specified range given in the Technical Specifications.
The AC Inverter operates under current control instead of the more common phase
control. This allows for a more robust interface to the utility and linear response in the
inverter dynamics.
In addition, references for the current are obtained from the utility waveforms, thereby
maintaining the AC Inverter as a true unity power factor interface regardless of line
harmonics.
Figure 2 shows the AC Inverter front panel. Each of the front panel controls and
indicators are described below.

locking mechanism and must be rotated counterclockwise to enable the
control power to repower the system.
NOTE:
The main circuit breaker must be switched off and locked out by
authorized factory personnel; and
, either the MAIN POWER or
EMERGENCY OFF switch service must be switched off to remove
power from the system for at least five minutes prior to accessing the
interior of the cabinet.

Inverter Fault, DC Converter Fault, Utility Fault, and Communication
Fault. (Refer to Table 5.1 in Section 5 of this manual to determine the
definition of any faults indicated.)
2.1.2 DC Converter Functions & Controls
The DC Converter monitors load connections, processes power from the Intermediate
DC Bus for the load, and provides a local control interface for the user.

ABC-170 Installation, Operation & Maintenance
11780-03-E Page 14 of 52 Webasto Charging Systems, Inc.
The DC Converter is composed of two separately controllable converters, converter A
and converter B. Each converter has its own set of front panel meters, mode select
switches and output terminals.
The converter has the ability to operate in two different configurations:
Independent Configuration: Two loads can be connected and separately controlled.
(The negative sides of the ABC-170 outputs are tied together when outputs are active,
so the two outputs cannot be placed in series.)
External Parallel Configuration: The outputs for both channels must be utilized for
parallel operation. The Channel A front panel limits and controles are used for this
mode. When using the External Parallel configuration, the output cables must be
connected together at the load, or at separate junction points and then to the load.
Alternately, the two bus bars provided with the system can be installed across the two
positive output studs and across the two negative output studs to enable external
parallel operation. Care must be taken to ensure the proper wire and lug size are used
to support the output current.
The DC Converter can present the power to the load using a variety of control algorithms
(modes). It can be operated as a constant current source, a constant voltage source or a
constant power source. In addition, limits value for voltage, current, and power are
specified by the operator to additionally constrain the output.
The internal contactors remain disconnected during load configuration or
reconfiguration, and will also be disconnected in the event of a load fault condition (e.g.,
a short circuit) or an unsafe operating condition (e.g., a voltage higher than the user-
defined limit).
Figure 3 DC Converter Front Panel
Figure 3 shows the ABC-170 DC Converter front panel. The displays and controls are
described below.

ABC-170 Installation, Operation & Maintenance
11780-03-E Page 15 of 52 Webasto Charging Systems, Inc.
CONFIGURATION
Pressed to select the load configuration and wiring connection.
There is one button each for PARALLEL
, RVS and
INDEPENDENT, respectively.
To change to PARALLEL Mode, the bus bars provided with the
system need to be installed to short both channels together.
Pressing the PARALLEL (yellow) button enables parallel
operation. Once a valid configuration has been selected, only the
appropriate button will remain lit (not flashing). After successfully
configuring the system, the user can pressed the RVS button to
enable Remote Voltage Sensing in either PARALLEL or
INDEPENDENT mode.
LIMITS
Pressed to set upper and lower operating limits for each
converter. The user presses either the UPPER or the LOWER
button to view the existing limit and holds the button down while
pressing the Up arrow and Down arrow buttons to adjust that
limit.
Upper and lower limit buttons are included for each converter (A
and B). When these buttons are flashing, the DC Converter is
prompting the user to check the operating limits and adjust them,
if necessary.
MODE
The MODE determines what control algorithm the converter will
use. The choices are VOLTAGE, CURRENT, POWER control
(green), or STANDBY (red).
When all four of these buttons on one converter (A or B) are
flashing, the DC Converter is prompting the user
to choose a
mode. When a mode has been selected, only the appropriate
button will be lit (not flashing) for that converter. Another mode
button may also be flashing at the same time if the DC Converter
is at an operating limit for one of the parameters that is not being
controlled.
STATUS
Each channel will display (remote) status independently (Remote
A and Remote B). When operating remotely, the REMOTE
button will be lit for that channel. At powered up, the system
begins in local operation.
PROTECTED
REMOTE
OPERATION
While operating in Remote mode, the user can change the status
of the ABC-170 to standby by pushing the Standby button. This
action will cause the output contactor to open, isolating the output
of the respected channel from the load. To re-
initiate Remote
mode operation, the user must manually push the flashing
Remote A/B button to resume operation under ROS control.

11780-03-E Page 16 of 52 Webasto Charging Systems, Inc.
2.1.3 Communication Between AC Inverter and DC Converter
The AC Inverter and DC Converter communicate over a RS-485 high-speed multiplexed
data bus. The communication bus is not intend to be accessed by the user at any time.
The AC Inverter sends information about its status and mode of operation to the DC
Converter. The DC Converter sends fault status information and communicates to the
Remote Operation System (ROS) via an RS232 link.
2.1.4 Remote Operation Interface
The Remote Operation Interface, based on the RS-232 communication standard, allows
communication between the DC Converter and the ABC-170 Remote Operating
Sysytem (ROS). The purpose of this interface is to provide status information and DC
output measurements from the ABC-170 to the ROS and to accept commands from the
ROS. For more information about the Remote Operation Interface, please refer to the
Remote Operation System Manual, Webasto document number 06631-03.
2.1.5 ABC-170 Remote Operation System (ROS)
The ABC-170 ROS is a personal computer based system for controlling the ABC-170.
The system consists of the computer itself and any peripherals, and the ABC-170 ROS
application.
This software provides a graphical user interface for controlling and monitoring the
operation of the ABC-170, a command language interpreter that allows for simple
implementation of complex test programs, communication with the ABC-170 system,
and the option of integrating external data acquisition devices into the system.
2.1.6 High Voltage Interlock (Front Panel)
Each channel of the ABC-170 has a High Voltage Interlock Switch (HVIS) for added
protection (Figure 4). The HVIS can put one channel of the ABC-170 into the STANDBY
mode without affecting the other channel.
Pin 1 (+V) is a system supplied +5 voltage source that is to be connected to Pin 2
(+sense). The Pin 3 (-sense) has to be connected to the Pin 4 (Gnd) signal, which is the
ground. A break in either one of these links will put the associated channel into the
STANDBY mode (open the output contactor and isolate the output of the ABC-170 from
the load). (See appendix V for proper wiring.)
NOTE: If this feature is not used, then it is necessary to have mating connectors with
jumper wires installed (see Appendix V) for the system to operate properly.
2.1.7 Remote Voltage Sense (RVS)
To increase voltage accuracy at the Load, activate the Remote Voltage Sense. This
feature shall be activated via ROS by pressing the button labeled RVS on the top left
side of the screen, or by pressing the RVS button on the front panel (RVS cable must
also be in place for both channels). The RVS feature can be used in voltage mode as
well as power mode (Figure 2.4). (See Appendix III for proper wiring and use of this
feature.)
