1. Introduction
The BMOD0058 E016 B02 (16 V) and BMOD0006 E160 B02 (160 V) energy storage modules are
self-contained energy storage devices comprised of either six or sixty individual ultracapacitor cells,
respectively. The modules include passively balanced ultracapacitor cells that are wave soldered
to a printed circuit board. Units may be connected in series to obtain higher operating voltages,
parallel to provide additional energy storage, or a combination of series/parallel arrangements for
higher voltages and energy. To provide long life, passive balancing is used to provide an equal
voltage bias to individual cells.
The module packaging is a rigid plastic enclosure. The enclosure is water resistant (per IEC 529
IP54). BMOD0006 modules have a voltage center tap for monitoring purposes.
2. Unpacking and Handling
2.1 Unpacking
Inspect the shipping carton for signs of damage prior to unpacking the module. Damage to the
shipping carton or module should be reported to the carrier immediately. Remove the module from
the shipping carton and retain the shipping materials until the unit has been inspected and is
determined to be operational.
NOTE: The original shipping materials are approved for both air and ground shipment.
The original shipping container should contain the following:

3. Installation
3.1 Mechanical
Modules have 6 (BMOD0058) or 12 (BMOD0006) clearance holes for mounting screw locations.
The modules can be mounted in any orientation.
General mechanical and mounting information is shown in Figures 1 and 2. Please see the
datasheet for additional dimensional information.
Figure 1: BMOD0058 Mechanical Configuration
Figure 2: BMOD0006 Mechanical Configuration
For best results the modules should not be mounted in locations where they are directly exposed
to the environment. The modules are built to IP-54 standards. In particular, areas of direct splash
should always be avoided. In systems that operate at voltages in excess of 60 V, appropriate

protection and sealing should be used on module terminals to avoid shock hazards and corrosion.
Note that the terminals are fully exposed to the environment.
Dimensional spacing of the mounting holes for the modules is shown in Figures 3 and 4. It is
recommended to leave at least 1 cm of spacing between modules along the vertical axis.

A proper installation should not exert any bending or twisting torque to the module enclosure.
Ensure that the module’s mounting points are co-planar within ±1 mm. If the actual mounting
location is out-of-plane, use spacers to bring all four mounting locations within plane to within
±1mm.
Both the BMOD0058 and BMOD0006 modules have been qualified to IEC60068-2-6 for vibration
performance. Ensure that this is adequate for the end-use environment. To ensure meeting
specified vibration performance, all mounting points should be used. If more severe vibration
performance is required, consider the use of isolators to provide damping. Contact Maxwell
Application Engineering for assistance in these cases.
3.2 Electrical
WARNING
CAUTION
To avoid arcing, the energy storage module should be in a
discharged state and the system power disconnected during
installation. The module is shipped discharged and with a shorting
wire. The shorting wire should be removed prior to installation of
electrical connections.
WARNING
CAUTION
To provide the lowest possible ESR the energy storage modules are
not fused. Care should be taken within the application to prevent
excessive current flow. Excessive current and/or duty cycle will
result in overheating the module and cause irreparable damage.
Please consult the specific data sheet for each module for current
and duty cycle capabilities.
The power output terminals of the modules consist of M5 screw terminals intended to mate with
spade or ring terminals. Ensure that interconnect wire is of sufficient gauge to carry the system
current. The modules may be connected in series for higher voltages. As mentioned earlier, the
maximum torque is 4 Nm.
The BMOD0006 modules have a center-tap terminal that can be used to compare the voltage of
the upper half of the ultracapacitor array with that of the lower half as a diagnostic for imbalance.
This mid-point voltage is accessible through the M4 monitoring terminals as illustrated in Figure 2.
The current drawn from the center tap should not exceed 10 μA. Drawing currents in

excess of this amount can create imbalance within the module. The maximum torque for this M4
terminal is 3.5 Nm.
The energy storage modules have low Equivalent Series Resistance (ESR). As a result, the
resistance of the wires connecting the energy storage module to the application can easily exceed
the ESR of the module. Connection of modules in series or parallel should utilize the same gauge
wire as determined for final output connections. When connecting in series connect the positive
output terminal of one module to the negative output terminal of the next module. Two possible
series orientations are illustrated in Figure 5. Possible parallel orientations are shown in Figure 6.

For both the BMOD0058 and BMOD0006 modules, the maximum allowable operating voltage for a
series string is 750VDC. Full UL810a compliance is satisfied for up to forty (40) BMOD0058
modules in series, corresponding to a system voltage of 640V. The BMOD0006 is not UL810a
listed.
When several modules are connected in series for operating at higher system voltages, care must
be taken to ensure proper creepage and clearance distances in compliance with appropriate
national and local safety standards for electrical equipment.
3.3 Thermal Performance
It should be noted that these modules are not intended for high cycling applications. Should there
be an interest in higher cycling applications, please consult Maxwell Technologies Applications
Engineering.
The thermal resistance, RCA, of the units has been experimentally determined assuming free
convection at ambient temperature (~ 25oC). The RCA value provided on the datasheet is useful
for determining the operating limits for the units. Using the RCA value a module temperature rise
can be determined based upon any current and duty cycle. The temperature rise can be
expressed by the following equation.
fCAESR dRRIT 2
where:
I = RMS current (amps)
RESR = equivalent series resistance, RDC (ohms)
RCA = thermal resistance (oC/W)
df = duty cycle fraction
The T value calculated above plus ambient temperature should remain below the specified
maximum operating temperature for the module (see datasheet).
4. Operation
The module should only be operated within specified voltage and temperature ratings. Determine
whether current limiting is necessary based on the current ratings of attached components.
Observe polarity indicated on module. Do not reverse polarity.

5. Safety
WARNING
DANGER HIGH VOLTAGE HAZARD!
Never touch the power terminals as the module can be charged and
cause fatal electrical shocks. Always check that the module is fully
discharged before manipulating the module. Please refer to the step by
step instructions below for the manual discharge procedure.
Do not operate unit above the specified voltage.
Do not operate unit above the specified temperature rating.
Do not touch terminals with conductors while charged. Serious burns,
shock, or arcing may occur.
Protect surrounding electrical components from incidental contact.
Provide sufficient electrical isolation when working above 50 VDC.
Prior to installation on or removal from the system, it is mandatory to
fully discharge the module to guarantee the safety of personnel.
WARNING
A fully discharged module may “bounce back” if it is stored without a
shorting wire connected to the + and terminals. This bounce back can
be as much as 2V for the BMOD0058 and 20V with the BMOD0006.
When used in series strings this has the potential to cause dangerous
electrical shocks.
6.1 Discharge Procedure
Proceed as follows to discharge the module:
1. Using a voltmeter, measure the voltage between the 2 terminals.
2. If the voltage is above 2V, a resistor pack (not supplied with the module) will need to be
connected between the terminals. Proper care needs to be taken in the design and
construction of such a dissipative pack. The resistor pack will need to be sized and
provided with suitable cooling to handle the resulting power dissipation. Additionally,
User Manual BMOD0058 & BMOD0006 Doc. No. 3000200.1
© 2013 Maxwell Technologies, Inc. Page 8
proper isolation and packaging are necessary to ensure safety.
3. If the voltage is under 2V, connect a shorting wire to the + and connectors.
4. The module is now safe for handling. However, leave the shorting wire connected at all
times until the module is installed in the system and the power cables are connected.
6. Maintenance
Prior to removal from the system, cable removal, or any other handling ensure that the energy
storage module is completely discharged in a safe manner. The stored energy and the voltage
levels may be lethal if mishandling occurs. Maintenance should only be conducted by trained
personnel on discharged modules (see above).

7. Storage
The discharged module can be stored in the original package in a dry place. Discharge a used
module prior to storage or shipment. A shorting wire across the terminals is strongly
recommended to maintain a short circuit after having discharged the module.
8. Disposal
Do not dispose of module in trash. Dispose of according to local regulations.
