With the current firmware, the PowerCal board can
perform programming and test of packs and modules
and the calibration of pack and cell voltages on packs.
Apply power (24V DC) to the board at either the JP
connector using an A/C wall adapter or at TBP
connector. To use a single PowerCal board connected
to the serial port of a PC, configure the COM and RX
jumpers for RS-232 and connect the P1 connector to
the PC serial port. To use multiple boards per COM
port, configure the COM and RX jumpers for RS-485
and connect the P1 connector to the RS-485 connector
on the PC card. Additional PowerCal boards my be
added by connecting J1 on the first board to P1 on the
next using a standard (straight-through) PC serial
cable. Up to seven boards may be added in this
manner. Use the ADR jumper to give each board a
unique address. Install and run Microchip’s PowerTool
software on the PC. The calibration platform is ready to
use.
3.1
Attach the external pack contacts of the Microchip
SmartBattery pack (V+, C, D, T, V-) to the same
terminals on the TBB connector. Using PowerTool
software, the EEPROM can be programmed and the
pack voltage can be calibrated. To program OTP
memory, the V
connected to V
connection is only necessary for OTP programming.
Additional PowerTool features, such as final test, can
also be performed on the pack.
3.2
Additional connections to the TBB connector are
necessary for the calibration of individual cell voltages.
The bottom of the cell stack is connected to V
top of the cell stack is connected to V1, and the
intermediate cell connections are made from the top-
down. In other words, V2 is connected to the next cell
below V1, V3 below V2, and V4 below V3. For 3-cell
packs, do not connect V4. For 2-cell packs – do not
connect V3 and V4. PowerTool software is used to
calibrate the cell voltages.
