SELECTING BATTERY CHEMISTRY AND NUMBER OF CELLS
For single cell Li-Ion, a 3,600 mA-Hr. battery with internal protection
circuitry is recommended for evaluation. For NiMH charge cycle, Panasonic
HHR-210AA/B2B batteries were used to develop the -dV/dt and +dT/dt ter-
mination methods.
Three push buttons are used to start a charge cycle, select chemistry and
select number of series cells. There are two LED’s, (green - NiMH, red -
Li-Ion) used to indicate chemistry type and four yellow LED’s to indicate
the number of series cells selected (D6, D7, D8, D9).
S1 (ON/OFF) is used to start and stop the charge cycle or to enter the
programming mode. When the input voltage is within the specified
operating range (+5.3V to +16V), press and hold the ON/OFF button for 5
seconds, all LEDs with the exception of D3 should flash. Release S1 and
STATUS LED (D3) will be flash, indicating that the board is in
programming mode.
