BattMan User’s Guide

1 Introduction

ADLINK’s BattMan (Battery Management) module is a Smart Battery Management System
that supports two Smart Batteries and provides ATX power for a mobile embedded system.
The BattMan Smart Battery Reference System is a proof-of-concept battery power
subsystem that allows for quick development and integration of battery power into a COM
Express system in the following ways:

f To emulate the battery power subsystem functionality of your prototype system during

the design phase

f As a ready-made battery power subsystem for your customized system
f As a reference design to integrate a battery power subsystem into your custom-designed

carrier (schematic provided)

The BattMan Smart Battery Reference System is compliant with the Smart Battery Manager
Specification and uses the System Management Bus (SMBus) for communications between
the battery power subsystem, Smart Batteries and host system (COM module and carrier).
The BattMan module is ACPI compliant and provides complete battery management under a
supporting operating system. ADLINK's COM Express modules feature a BIOS that fully
supports all Smart Battery communications using existing interfaces defined in the COM
Express specification and are fully compatible with the BattMan module.

The BattMan module delivers power output to a standard ATX 20-pin connector and provides
an Auxiliary Power 4-pin Molex connector for storage devices. Power input is from a 19V AC/
DC adapter. When not connected to a host system, the BattMan module can function as a
stand-alone battery charger.

2 Electrical Specification

The Battman module is a single or dual Smart Battery Manager. The module supports a
standard 2.5 mm DC Input Jack for connection of a standard 19V AC/DC power adapter. The
battery charger output voltage is configurable to adapt it to battery packs consisting of 2, 3,
4 or 5 Li-ion battery cells*. The module can work in either notebook mode (ACPI) or as
stand-alone battery charger.

* Battery packs with 2 or 3 cells cannot provide 12V output and will not support the
requirements of COM Express systems.

2.3 Functional Characteristics

f Dual Charging - charges two Smart Batteries simultaneously to reduce charging time
f Simultaneous Discharge - simultaneous dual discharge increases battery operating

time by reducing internal battery losses due to high discharge rates

BattMan User’s Guide

3 Functional Block Diagram

The BattMan module provides 12V and 5Vsb to the COM Express Carrier Board and 12V and
5V to the Auxiliary Power connector to support a storage device.

The BattMan module communicates with the COM Express host system via the Host SMBus
interface. The BattMan module acts as a slave and the COM Express module sends
commands to the BattMan module to get information. The three SMBus signals SMB_CLK,
SMB_DAT and SMB_ALERT# correspond to pins B13, B14 and B15 on the AB connector of
the COM Express module. A Local SMBus is used for communciations between the BattMan
module and Smart Batteries.

6 Module Configuration

6.1 Operating Mode

The BattMan module supports two operating modes that are configurable by jumper setting:

f Battery Management Mode - connects with the COM Express host system via the Host

SMBus interface to function as a Smart Battery Management System

f Stand-alone Charger Mode - acts as a stand-alone charger for two Smart Batteries

The operating mode is set using jumper JP1.

JP1 Mode

1-2 Battery Management Mode (default)
2-3 Stand-alone Charger Mode

6.2 Charger Enable/Disable

The BattMan module charger function can be enabled or disabled by jumper setting. When
the charger is enabled and the 19V AC/DC power adapter is connected, Smart Batteries
connected to the module will be charged automatically according to the battery status. When
the charger is disabled, Smart Batteries connected to the module will not be charged.

JP1

The charger function is set using jumper JP2.

JP2 Mode

1-2 Enabled (automatic charging) (default)
2-3 Disabled (charger OFF)

6.3 Indicator LEDs

LED4
LED1
LED2
LED3

There are four LEDs to indicate the Operating Mode and Charger Status of the BattMan
module. The functions of LED1~4 are dependent on the settings of JP1 and JP2.

When in Battery Management Mode (JP1 pins 1-2 shorted), LED1/LED2 are connected to the
Host SMBus clock and data signals and are ON to indicate that the BattMan module is
actively communicating with the Host System. LED3 is connected to the SMB_ALERT signal
and will light briefly during system power up but will remain OFF during normal operation.

When in Stand-alone Charger Mode (JP1 pins 2-3 shorted), LED1 is OFF and LED2/LED3
indicate the charging status of Battery2/Battery1 respectively (ON if charging).

LED JP1 (1-2) Battery Management Mode JP1 (2-3) Stand-alone Charger Mode

1 (ON) SMB_CLK Active OFF
2 (ON) SMB_DA T Active ON if Battery2 charging
3 SMB_ALER T Active ON if Battery1 charging

When the charger is enabled (JP2 pins 1-2 shorted) and the 19V AC/DC power adapter is
connected, LED4 is ON. When the charger is disabled (JP2 pins 2-3 shorted) or the 19V AC/
DC power adapter is not connected, LED4 is OFF.

LED JP2 (1-2) Charger Enabled JP2 (2-3) Charger Disabled

4 ON (charger enabled & 19VDC present) OFF (charger disabled or no 19VDC)

6.4 Battery Settings

The BattMan module has been designed to provide power to COM Express systems using
battery packs having 2, 3, 4 or 5 Li-ion cells in series. There are two jumper settings that
must be set according to the number of cells in series in the battery pack:

f Maximum Charge Voltage - protects the Smart Battery from charging with excessive

voltage

f Low Battery Voltage Trip Threshold - protects the battery from excessive power drain

Maximum Charge Voltage (CN5)

The Maximum Charge Voltage setting is a hardware limitation on the
charging voltage supplied to the Smart Battery. The CN5 jumper setting
determines one of four voltage limits that are applied to the charger voltage
output value. These limits provide a measure of safety with a hardware
restriction on charging voltage, which cannot be overridden by software. This voltage sets
the limit that will be applied to the battery as reported by battery. Since the battery internal
voltage monitor point is the actual cell voltage, you may see higher voltages (up to 512mV
higher) at the external charger terminals due to the voltage servo loop action.

CN5 Max Charge Voltage Li-ion Cells per Battery

1-2 8.2 V 2
3-4 12.6 V 3
5-6 16.8 V (default) 4
7-8 21 V 5

Low Battery Voltage Trip Threshold (CN2)

This jumper provides a user selectable voltage trip threshold to protect a
Smart Battery from over discharging and effectively damaging the battery. The
voltage trip threshold setting depends on the Smart Battery output voltage
which in turn depends on the number of cells in series in the battery pack.

8.3 Windows OS Interface

Device Presence

ADLINK's system BIOS fully supports the BattMan Smart Battery Reference System and
reports the presence of a Smart Battery device to the OS. In Windows, the battery power
subsystem information is listed in the Device Manager under the "Batteries" category. The
system BIOS will check the current system configuration and then report back to the OS.
There are three possibilities for the battery report information.

No battery power subsystem present

The system BIOS checks for the presence of a charger, selector or system manager. If there
is no device attached, it will only report the presence of an AC adapter to the OS.

BattMan module present

If the BattMan module is present in the system, the system BIOS will report an AC adapter
and two battery devices to the OS.

Page 24

BattMan User’s Guide

Battery State Notification

The system BIOS is notified of the state of the battery power subsystem (AC power or battery
mode) when it receives an SMBALERT# as a SCI event. An alert may be sent to update the
charging state, remaining battery capacity, or presence of an AC adapter. The OS can also
query the system BIOS to update the battery power information. Placing the cursor over the
battery state icon will cause the OS to update the battery power information.

When an AC adapter is inserted or removed, the battery state icon in the taskbar will change
to indicate the current state. To display the battery state icon in the taskbar, enable the
option "Always show icon on the taskbar" from the "Advanced" tab of "Power Options
Properties".
