Arbin Instruments A multiple independent channel test station fine-tuned for testing bat eries, superca-pacitors, and other energy storage devices. The BT-I Series provides individual voltage clamp safety limits for testing to prevent damage to the devices being tested. Includes a PC preloaded with our MITS Pro and Data Watcher software for writing test schedules, monitoring real-time data, and reviewing and plot ing test results. Primary Applications: MODEL VOLTAGE CURRENT ■ Lithium, Lead-acid, Nickel & Alkaline Battery Testing ■ BT-I-100 (-2)V to 10V ± 10A/100mA/1mA Smal bat ery packs ■ Half cel testing and materials research BT-I-200 OV to 20V ± 10A/100mA/1mA ■ Primary & secondary bat ery testing ■ Multiple independent channels, where each channel functions independently to run multiple experiments simultaneously. ■ Each channel comes with three current ranges with 16 bit resolution. ■ Advanced software package, MITS Pro (Multiple Integrated Testing System, professional version), provides flexible scheduling, user-friendly interface, distributed system control and data acquisition ■ Software provides easy data analysis and plot ing based in Data Watcher or Microsoft Excel ■ In multi-electrode applications, each channel accommodates an individual RE, or several channels can share one RE (such as in a combinatorial cel ). This results in accurate control and measurement and enables individual IR drop compensation. Channels share ground as the counter electrode (CE). ■ Each channel in the test station wil be safely control ed by their own Voltage Clamp Value ■ User-defined value set in the software that is applied at the hardware level. The system wil not al ow the voltage to go above or below the set clamp values on al channels to keep bat eries within the safety set ings. ■ The system provides a Low Voltage Clamp Value and High Voltage Clamp Value BT-I +1 979 690 2751 www.arbin.com Arbin Instruments Model Number: BT-I-100 BT-I-200 MODEL NUMBER BT-I-100 BT-I-200 Bipolar Linear Circuit Type Provides zero switching time between charge and discharge Circuit Board: 2243-4 Voltage Range (max/min) -2V to 10V 0V to 20V Accuracy of Voltage Control & Reading ±10mV, 0.05% Ful Scale Resolution Current Ranges Provided High: 10A ± 10mA High: 10A ± 10mA 0.05% Ful Scale Resolution Medium: 100mA ± 100uA Medium: 100mA ± 100uA Low: 1mA ± 1uA Low: 1mA ± 1uA Minimum V at Maximum Current -2V @ 10A 0V @ 20A Maximum Continuous Power Output/Channel 100W 200W Voltage Measurements Input Impedance ~10GΩ Current Rise Time 100-150µS Time required for current output to get from 10%-90% of requested value Current and Voltage Resolution 16 Bit or 0.0015% FSR Voltage Clamp Individual Voltage Clamp Connection for Batteries Standard 6 ft. cables with al igator clips Arbin can also provide different bat ery holder options to allow easy engagement of the device to the test station Connection to Computer TCP/IP Ventilation Method Air cooled, front-to-rear airflow Room Operating Temperature 10 to 35 degrees C Computer Specifications PC with 22” flat-screen monitor is included, preloaded with our MITS Pro testing software CHASSIS SIZE OPTIONS CHANNEL NUMBER OPTIONS 15” X 30” X 25” 4 4 30” X 30” X 45” 32 32 30” X 30” X 77” 64 64 Arbin can provide input power options of 110V or 220V Single Phase, or 208V, 380V or 480V Three Phase System power input options are determined by customer site and system power required. BT-I +1 979 690 2751 www.arbin.com Arbin Instruments Model Number: BT-I-100 BT-I-200 Current (A) Outputs constant current to the cel or bat ery at the value specified Positive current refers to charge and negative current refers to discharge Voltage (V) Outputs constant voltage to the cel or bat ery at the value specified C-Rate C-Rate is a method for indicating the discharge as wel as the charge current of a bat ery. It can be expressed as I=M*C where I=current A; C=bat ery capacity; M is the C-rate value. Rest The bat ery is disconnected from the charge/discharge circuit but remains connected to the voltage measurement circuit to enable open-circuit voltage measurement Power (W) Outputs constant power to the cel of bat ery at the value specified. This is accomplished by iteratively measuring the bat ery voltage and calculating the current necessary according to Ohm’s law in order to achieve the power level set by the user. Each time the channel is sampled, the calculation is preformed al owing the current to quickly stabilize at the desired power level and maintain this power level as the voltage changes. Load (Ohm) Applies a constant resistance load to the bat ery at the value specified. A positve value for load wil result in a positive current and a negative value for load wil result in a negative current Set Variable(s) Change test related variables including channel capacity, energy, and al test counter variables Current Ramp Generates a current ramp with a positive scan rate for increasing current and a negative scan rate to generate decreasing current ramp Current Staircase Generates a current staircase with increasing current and negative decreasing current staircase with adjustable step amplitude Current and Voltage Non-standard time-domain functions may be input ed from external sources such as ASCI data Simulation streams and used as control parameters for repetitive tests DC Internal Resistance This function applies a 10-pulse train with 1ms pulse width of the specified magnitude fol owing a constant-current charge or discharge step Current CV Mode to create linear sweeps in one step, eliminating the need to jump steps or reverse sweep directions CC-CP Combine constant current control and constant voltage control into one stage “CC-CP” End Conditions Time, Voltage, Current, Capacity, Energy, ΔV, DV/dt, formula, meta-variables, and other combinations Data Logging Rate During a standard step: 40-150 data points per second, per PC Network Capabilities Provide TCP/IP access for networking Data Result File Imported into Microsoft Excel; Arbin’s Excel Data Pro macro included for easy data manipulation Data File Content Channel data; test time, step time, voltage, current, capacity, energy, first/second derivative of I or V, auxiliary input data (optional). Statistical data: cycle #, cycle capacity/energy, max voltage, etc. BT-I +1 979 690 2751 www.arbin.com Arbin Instruments Model Number: BT-I-100 BT-I-200 Arbin Instruments provides a wide variety of auxiliary modules for expanding the capability of the main I, V control circuitry. Each module plugs securely to the bus board. These auxiliary modules are classified as input, input/output, and control modules. Input Modules: Auxiliary inputs can be used to record desired data as wel as to terminate or regulate charge and discharge processes based upon measured conditions. Selectable inputs are of V (voltage), Input / Output Modules: Digital I/O is an integrated peripheral on/of control. The output commonly is used to control valves and switches. The input al ows an external control signal to control testing procedure. Control Modules: Arbin provides control modules for Auto-Calibration, Smart Battery Testing, External Charger, Temperature Chamber Interface and AC Impedance Measurement. For more information please visit: www.arbin.com/products/accessories/auxiliaries.htm Several safety provisions are provided in every Arbin system. There are three levels of fusing provided inside the system for further protection at the channel, board, and power supply levels. The software also has several safety functions with which the user can avoid over charging the cel s, over discharging, overheating, etc. Smart UPS: This option uses a very smal Smart UPS to back up power to the computer only. This al ows the user to enable auto resume options to al of specific channels after a stop due to power interruption. Provision is provided for the user to intervene if they so desire before the channels resume. This is an essential component for any user with an unreliable power source unless you have the whole facility on backup power. BT-I +1 979 690 2751 www.arbin.com
