USERS MANUAL ISL94212EVKIT1Z UG048 Rev 0.00 Evaluation Kit User Guide August 26, 2015 Description Key Features The ISL94212EVKIT1Z is a kit that facilitates use of the Supports both stand alone and daisy chained configurations ISL94212 BMS device. The ISL94212 monitors cell voltage and Daisy chaining with both connector only or wire jumper temperature. It converts the cell voltages and temperatures to options 14-bit digital values, provides cell balance control, It provides GUI provided export option for generation of detailed significant fault detection. The ISL94212 can operate in a single register and/or SPI communications log files. device configuration, or multiple kits can be cascaded using a built-in daisy chain connection. The daisy chain hardware USB dongle runs HID firmware for driver-less enumeration provides robust, redundant board-to- board communications. and communications with Windows platforms GUI add-in chart generation tool supports real-time Specifications graphing, zoom and export of captured data. This board has been configured and optimized for the following Software provides checksum requirements associated with operating conditions: daisy chain communications. Kit includes Battery Emulation board(s) for cell voltages V = 6V to 60V BAT generation.

One daisy chain cable Functional Description What is needed The ISL94212 evaluation Kit, coupled with the associated GUI provides the means to familiarize oneself with the various The following instruments will be needed to perform testing: instructions capability and operation of the device. A single 60V/1A adjustable power supply ISL94212 Li-ion battery manager IC supervises up to 12 series connected cells. The part provides accurate monitoring, cell Wires to connect power supply to MCB PS2 Z board balancing and extensive system diagnostics functions. Precision multimeter The kit enables the user to activate and data log voltage and Oscilloscope (optional) temperature measurements. Cell voltages are supplied via a resistor ladder network in the MCB PS2 Z multi-cell power Cables and wires (Optional) supply test board. Windows computer with USB port The ISL94212 has three cell balancing modes incorporated: Manual Balance mode, Timed Balance mode and Auto Balance Operating Range mode. The auto balance mode terminates balancing functions when a charge transfer value specified by the host Single device setup (non-daisy chain) mode can operate with a battery voltage of 6V to 60V. When using less than 12 cells, the microcontroller has been met. Note: Cell balancing will require user should consult the datasheet regarding cell connections. the removal of the MCB PS2 Z multicell power supply test board and attachment of Cell devices that are capable of sourcing and However, caution should be employed during daisy chain sinking current. operation. In this mode, up to 14 boards can be connected. While each board is operating on a relative voltage of up to 60V, this The ISL94212 communicates to a host microcontroller via an SPI interface and to other ISL94212 devices using a robust, two-wire floating is accomplished via the AC coupling of the daisy chain circuits.
