Lithium Ion Battery Management
System for 12V—48V Applications
(Revision C)
Designed Use
 Designed for Lithium Ion battery packs up to 48V nominal (60V max)
 Individual cell voltage rating: 0.2v to 5v per cell tap
 Supports from 1 to 16 cells in series
 -40C to 80C operating temperature range
 Integrated low loss passive cell balancing to within 10mV
 Cell voltage resolution of about 1.5mV

Applications
 Light mobile applications (scooters, golf carts, etc.)
 Solar & wind energy storage
 Uninterruptible power supply
 Battery backup
Basic Functions
 Over-voltage and under-voltage protection
 Over-current protection
 Temperature protection
 Intelligent cell balancing
 State of charge monitoring
 State of health monitoring
Additional Functions
 Data logging capabilities
 Stored diagnostic information
 Programmable interfaces
 Current limit calculations (intelligent current limiting)
 Stored battery usage statistics including histogram data
Display Options
 Interfaces with third party smartphone software (CAN version only)
 Optional basic state of charge display
 Optional data logging display
Interfaces
 2 digital signal outputs for controlling charge and discharge limiting mechanisms
 1 digital signal output for controlling a battery charger
 1 CANBUS 2.0B interface [optional] (both standard and extended IDs supported)
 1 digital RS-232 interface for programming and diagnostics
 3 multi-purpose outputs with software assignable functions (2 on Rev. B)
 1 multi-purpose input with software assignable functions
 3 analog 0-5v outputs that represent the following signals: Charge Current Limit (CCL), Discharge
Current Limit (DCL), State of Charge (SOC).
 3 thermistor inputs (additional monitoring possible with thermistor expansion module) (2 on Rev. B)
Features
 Centralized design allows for faster polling of data resulting in increased accuracy and resistance
to EMI
 No cell boards (all electronics are contained within the unit.)
 Supports OBD2 protocol for storage of diagnostic trouble codes, freeze frame snapshots and
polling of live data
 PC software can be used to monitor battery performance, read and reset trouble codes, program
battery profile information, and update settings
 Accurate amp-hour and pack state of charge tracking (with correction based on cell open voltage)
 Retains data when power is lost (no always-on power source needed)
 Charger integration to allow for tapering of current during charge (if supported by charger)
 Battery profile information and settings are field programmable via PC utility.
 Internal resistance is measured for all individual cells
 Pre-calculated charge and discharge current limits
 Stores a snapshot of active data when faults occur for easy problem diagnosis.
Dimensions
 7.14 in (W) x 4.01 in (L) x 1.50 in (H)
