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.
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.
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.

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. 6.
6.3 Indicator LEDs 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.
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.

8 Getting Started This chapter describes how to connect the BattMan Smart Battery Reference System to power a COM Express system and access the battery power subsystem information under Windows OS. 8.
8.2 Cable Connections The BattMan module connectors are shown in the diagram below. 19V DC Power to Carrier Board SMBus to Host System Battery 1 Auxilary Power Battery 2 Be sure to set JP1 and JP2 to the correct settings for your battery packs before connecting the AC adapter to the BattMan module. See Section 6.4 Battery Settings. 1. Connect the ATX Power output of the BattMan module (CNX2) to the ATX power input of the COM carrier board using the 10-pin to 24-pin ATX cable provided. 2.
The figure below shows a BattMan Smart Battery Reference System connected to an Express-BASE carrier board with COM Express module and SATA hard drive. AC Adapter ATX Power SMBus Aux.
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.
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.
