Part # PS042 PS044 Description PowerCal calibration board CellSim board (optional)
Development / Test Software
Part # PS040 Description PowerToolTM
performs loading and verification of battery configuration parameters and 3D cell models in Accuron EEPROM and OTP memory. In addition, PowerCal provides a complete precision system for calibrating current, voltage, and temperature measurements in a smart battery, eliminating the need for expensive meters or power supplies. During calibration, PowerCal accurately measures current, voltage, and temperature and compares these measured values to those 1

PowerSmart PowerTool Product Brief reported by the smart battery. Calibration values are then loaded into the Accuron programmable storage and used by the chip to compensate raw measurements made during normal operation. Reported values from the Accuron are therefore corrected to eliminate known, measured errors. PowerCal accomplishes calibration with a programmable load and precision A/D hardware so that a known, constant discharge current is drawn from the battery pack. The programmable load circuit is capable of drawing up 36W continuous discharge power from the battery pack during calibration using naturalconvection cooling. Higher discharge currents are supported at reduced duty cycles, and/or with forced-air cooling. In addition, there are provisions for the user to add their own external charger or load, at up to 10A. PowerCal is designed to support both development and test environments. Both RS232 and RS485 interfaces are present so that the board can operate with a stand-alone connection (RS232) or with a multidrop connecton (RS485) to the host PC. The hardware supports up to 7 PowerCal boards interfaced on a multidrop link from a PC COM port. As a result, up to 28 boards can be interfaced on a single PC with 4 COM ports. PowerCal boards can fit in a DIN 6U rack (2.25" board spacing); they can also be panelmounted.
Preliminary Extensive safety features including production proven EMI / ESD protection, fuses for device under test, and optical isolation for serial ports. The board is implemented using 4 layers with a dedicated ground plane. All I/O's are connected to bypass capacitors to earth ground. Development Tool Summary PowerSmart provides all the necessary hardware and software to enable easy tailoring of battery control algorithm parameters and cell performance models to meet specific application requirements and attain the highest accuracy available anywhere.
