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 Voltage Ramp Generates a voltage ramp with a positive scan rate for increasing voltage and a negative scan rate to generate decreasing voltage ramp Current Staircase Generates a current staircase with increasing current and negative decreasing current staircase with adjustable step amplitude Voltage Staircase Generates a voltage staircase with increasing voltage and negative decreasing voltage staircase with adjustable step amplitude Current & Voltage Pulse Applies a predefined voltage or current profile to the cel or bat er pack under test Current & Power Simulation Non standard time domain functions may be interrupted from external sources such as ASCI data streams and used as control parameters for repetitive test 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 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 combi-nations BT-2X43 +1 979 690 2751 www.arbin.com Arbin Instruments Model Number: BT-2043 BT-2143 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. 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), T (temperature), and P (pressure). Control Modules: Arbin provides control modules for Temperature Chamber Interface 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-2X43 +1 979 690 2751 www.arbin.com
