1.0 GENERAL DESCRIPTION
The PS5100 module is a complete Smart Battery
controller subsystem based on the Microchip PS501
battery manager with patented Accuron® technology.
The module is designed to operate in a battery pack
consisting of six (6) to twelve (12) series connected
Ni-based cells. The module consists of the Microchip
PS501 battery manager IC with a four LED SOC
display and an optional connection for an external
thermistor.
1.1 Quick Start – Pack Assembly
Follow these directions to assemble a pack with the
PS5100 module.
• Use standard precautions when handling static
sensitive devices.
• Modules should be connected to battery cells in
the order indicated below to insure proper start-up
and operation. Wires should be attached to the
modules first and then connected to the battery
cells as instructed.
• The connection sequence is critical to successful
use of the PS501 family of CMOS ASICs. The
pack positive should be securely connected to the
module first, followed by pack negative.
Step 1) Configure the module for optional external
thermistor use. PS5100 modules are
shipped configured to use the internal
temperature sensor only. To add an
external thermistor to the board, remove
resistor R16 and connect the thermistor
across via TN and TR. A parameter change
is required to enable the external thermistor
measurements. Bit 5 of Flags1 must be
cleared.
Step 2) Connect wires to module. Use large
diameter wire (18 AWG-20 AWG) for
current carrying lines from VR and V1. All
others are signal only lines (24 to 22 AWG).
Step 3) Connect V1 to the most positive point on
the battery cell stack.
Step 4) Connect VR to the most negative point on
the battery cell stack.
Step 5) Connect external connector to BN, T, C, D
and BP.
Step 6) Program the assembled pack using
Microchip’s PowerTool™ 500 software and
PowerCal™ 2 board or PowerInfo™ 2
board hardware. The module is shipped
with default configuration values for a six
series cell pack. The Configuration Wizard
guides the user through basic configuration
and initial download. All of the configuration
parameters can be changed at will using
the utilities on the Parameters page in the
PowerTool 500 software.
Step 7) Calibrate the pack using the PowerTool 500
software and PowerCal 2 board hardware.
The pack is now ready for use.
