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. FIGURE 1-1: CONNECTIO N POINTS (SIDE 1) BP C TD BN VR V1 VP TN TR

2.0 FUNCTIONAL DESCRIPTION
2.1 PS501-0901 Fuel Gauge
The module fuel gauge provides State-Of-Charge (SOC) and battery status data in accordance with the SMBus standards version 1.1. The PS501-0901 monitors the pack voltage, battery temperature and current to determine SOC and battery status. The State-Of-Charge calculations compensate for cell self- discharge and charge acceptance. The remaining time calculation compensates for temperature and discharge rate. The parameters for determining battery status flags and alarm thresholds are all programmable as is the battery design capacity and the battery perfor- mance model data. Please refer to the data sheet “PS501-0901, Single Chip Field Reprogrammable Battery Manager – Nickel Chemistries” (DS21902) for details on configuring the PS501-0901.
