Large Sized Battery Power Systems, Battery Cluster Building Blocks
 

 


Energy Dense Power Systems IBPS building blocks allow system designers to build very large capacity Li-ion battery systems. The IBPS MP-Series and XP-Series controllers support building power systems with over 10,000 watt-hours of high density rechargeable Li-ion battery power. These systems are built out of small safe Li-ion smart battery packs that can be shipped via any means when disassembled. Li-ion batteries that are above 100 Whrs are typically treated as DOT Class 9 hazardous goods.  Energy Dense Power System Packs are 95 Whrs. The picture below shows the basic building block to build a very large battery system.  Multiple XP-08S battery clusters (760 Whrs) can be grouped together with CB-04 communication modules to build virtually any size battery system.  Lower current requirements can use MP-08 modules.

Example: The system below shows a 32 pack battery array. The system has 3000 watt-hours of capacity and will produce 720 Watts of regulated 48V output with 3 DC2U-1V DC-DC converters. This subsystem is very compact due to the high energy density of the Li-ion cells and can be fully charged in 3.5 hours. Each battery pack has a complete safety circuit, fuel gauge and communication port that is used by the system to collect detailed information about each pack's operation.
Block Diagram: Shows the components used to create the 3000 watt-hour battery array. The configurations are plug and play and are constructed out of standard building blocks and stock cables.

XP-08, MP-08, XP-04, MP-04 IBPS Smart Battery Controllers
The XP/MP-08 and XP/MP-04 battery controllers are intelligent devices that allow users to attach Smart Battery packs to supply a common load. The MP-xx and XP-xx controllers are microprocessor controlled and monitor the safety and power information from each "Smart" battery pack attached to the controller. The MP-04 and XP-04 controllers are single modules and support up to four Smart Battery Packs, the MP-08 and XP-08 are a two module stack and support up to eight Smart Battery Packs.  The XP Series adapters can support higher power requirements than the M P Series.
The XP-xx and MP-xx series of controllers support operating in clusters with other XP-xx and MP-xx controllers. The devices work in harmony load sharing and sourcing a common load device (your system being powered). These controllers support charging from weak sources such as Solar Panels or Fuel Cells and can do charge balancing across the cluster.
The XP-xx and MP-xx controllers have lower RDs FETs than used on the BB-xx series controllers to support higher currents. The main FETs are covered with a heat spreader / sink to help aid in keeping the junctions cool.
The design of the XP-xx and MP-xx controllers are such that when the Charge Voltage is present the FETs will source the load from the Charge Voltage and switch the batteries offline and start charging them. If the load is not too large and the charge voltage supplies are sized correctly you may be able to operate your device while plugged into the charge voltage. The XP-04 and MP-04 controller boards are single modules that supports a maximum of four battery packs on a single module.

DC2U-1V: Regulated DC-DC Converter Modules
The DC2U-1V  module is a 240 Watt output module that provides either 19V, 24V, 28V or 48V jumper selectable output.. The DC2U-1V  is produced in a standard PC104  form factor with Molex connectors for making the system connections.  In addition, multiple DC2U-1V modules can be used in parallel with MP-xx or XP-xx series controllers to support battery clusters with very high power requirements.  This is used in applications where space is a premium.
The example picture shows DC2U-1V DC-DC Converter modules can be stacked or spaced out individually depending on your application .   These converters can produce up to 240 Watts individually or multiple units will work in parallel to meet higher power requirements. Energy Dense Power Systems also offers other regulated DC-DC Converts please visit our products page:
The standard modules can be easily packaged together in a weatherproof box to provide large portable power sources.  The above box offers 760 Whrs of power with regulated output.  The above power box could power a 20 watt notebook computer for 38 hours without recharging.
PS-600 DC Power Supply, 18V, 600Watts, N+1 operation
The PS-600 option is provided to supply the charge voltage in larger battery cluster systems. These power supplies can be connected for parallel operation to scale the power output.
The following example shows a four supply user configuration that can supply 2400 Watts of output power for charging. In this configuration the device is connected to t he supply when it requires a charge. The array of battery packs is fully charged in under 4 hours.

IBPS Battery Monitoring Windows™ Software Applications
Intelligent Battery and Power System (IBPS)
The standard Base Battery Controller Module, BB-04, with the DC-023,
DC-DC Converter Module, forms the basis of a very flexible and efficient
power supply and battery contro ller.  This subsystem allows engineers
to design a power supply with Lithium-ion (Li-ion) battery back-up or
battery power. It can be used to make instruments or electronic
devices portable or uninterruptible if AC power is lost. The BB-04
module supports up to four BA-95HC Smart Li-ion battery packs
allowing between 95 and 380 Watt-hours of battery power. 
The next generation BB-04SR/FR module and DC-DC Converter
DC123SR are RoHS compliant and are recommended for most new
designs.  The DC123SR can provide up to 144 Watts compared to
the DC023 unit's 100 Watts.
The IBPS (BB-04 or BB-04SR/FR) operating model is similar to the
power supply in a notebook computer. When AC is plugged in (charge
voltage present) the system runs from the charge voltage and the
remaining power is used to charge the battery packs. When the
charge voltage is removed, (loss of AC or source unplugged),
the regulated DC outputs switch over seamlessly to battery power.
Below are two examples of systems using the IBPS.
Example 1: PC104 Embedded Computer and LCD Display (12V)
powered from a BB-04 module, four BA-95 battery packs (flying lead
and backplane shown as an example), and DC-023 module. This
Windows™ system consumes 35 Watts of DC power at peak. The
system will run indefinitely with the AC (Charger 18V) applied and
switch automatically to battery power when the charge voltage is
removed. With the four packs, the system will run between 12 and
20 hours (20 hours if display is blanked).
Example 2: This standard tower PC system was converted to
Battery Power using an Energy Dense Power System's Standard
Evaluation Kits and two BA-95HC battery packs. The system will
operate for over 3 hours when the CPU is running; about 6 hours
when the CPU is in power saver mode. The maximum power
observed was 100 Watts. A single battery pack can source
about 60 Watts, two packs will source this 100 Watt max system.
The IBPS hardware operates like a notebook computer, i.e.
charging and running the system when AC is present (18V DC
charge voltage) and automatically switching to battery power
when the charge voltage is removed.


This is a block diagram of a basic power controller system. The
EK-02 kit has been replaced by the EK-04, regulated output
evaluation kit.  This shows two BA-95HC battery packs included.
The "MINIBATS" Windows™ software utility is provided to
monitor the status of the battery subsystem when it is powering
a Windows™=2 0X86 system.
BB-04 Unregulated Battery Cluster, 380Watt-hours, 11-18V
raw output  
 
BB-04 & DC-023 Regulated Battery Cluster, 380Watt-hours,
ATX Power output
Product Description
BB-04 & BB-04SR/FR Base Battery Controller
The BB-04 or BB-04SR/FR module manages up to four Smart Li-ion
battery packs. They manage the charge and discharge of all packs
as well as load balancing and real time status reporting from each
battery pack. The module includes four level 3 smart battery
chargers (Smart Battery Charger Specification, V1.1) that will
simultaneously charge all battery packs when an 18V DC charge
voltage is provided to the DCIN connectors. The charge voltage
will also source the power to the user device.
The BB series units communicate to the host system via an RS232
port and reports real time status. The BB-04 or BB-04SR/FR
working with the "MINIBATS" program on a Windows™ host
system will perform the functions found on a notebook computer.
The "MINIBATS" program can take action when the system's
battery capacity reaches user determined set points. The three
actions are (1) "warning" system power low; (2) run a program
or (3) shut down (or hibernate) the Windows™ computer.
DC-023 & DC123SR Power Supply Module w/ATX Functions
The DC-023 DC-DC Converter Module provides very high efficiency
regulated DC output s of 3.3V, 5V and 12V to operate the user
electronics and computer hardware. The DC-023 Power Supply
can provide a MAXIMUM of 7Amps @ 12V, 10 Amps @5V &
3.3V. The PC104 sized module has both an ATX connector and
a six pin Molex connector that provides the three voltages.
The DC-023 Power Supply is sized to power any embedded
computer system, CPU, disks, I/O and user electronics. If
you need additional power at a given voltage you can
connect two DC-023 modules and double the current from
any voltage rail. The ATX connector provides the POWERON
and POWEROK signals for ATX motherboards. However, it
does not provide -12V, -5V and 5VSB signals. The 5VSB
output is supplied by the switched 5V and requires the user
to setup the motherboards to TURN ON after POWER FAIL.
The module can power most standard PC motherboards.
Small motherboards under 60 Watts like the VIA EPIA
(20 Watts) can run on a single battery pack; motherboards
between 60W and 110 Watts require two BA-95 battery
packs to provide sufficient power to operate the load.
The DC123SR module is RoHS compliant and supports
higher power applications compared to the DC-023
power supply. The module outputs the same regulated
voltages as the DC-023 (3.3V, 5V, 12V) and has -12V
standard.  The 12V output can run up to 12 amps. 
In addition, the module comes in a small form factor
2.91" x 3.58".
