Operational Description
This is the full charging current that the battery requires
during normal charging. It can be broadcasted to the charger
or read from the PS501.
ChrgCurrOff

Trickle charging current. This is a small amount of current
that the charger should deliver when full charging needs to
be halted temporarily due to high temperature.
ChrgMaxTemp

0

235
Temperature threshold when charging,
Coded value = (Celsius * 10 + 200)/4. When the temperature
exceeds ChrgMaxTemp and the battery is charging, then
ChargingCurrent is set to ChrgCurrOff and ChargingVoltage
is set to ChrgVoltOff .
ChrgMinTemp

0
255
50
Low temperature threshold,
Charging coded value = (Celsius * 10 + 200)/4. When
charging, if the temperature is less than ChrgMinTemp , then
ChargingCurrent is set to ChrgCurrOff and
ChargingVoltage is set to ChrgVoltOff .

Voltage required when charging should be halted.
Reset FULLY_CHARGED bit at this level, 100 = 100%. Once
the FULLY_CHARGED bit is set, taper or pulse current will
not be monitored any more. When discharging begins, the
FULLY_CHARGED bit must remain set until the cell voltages
are below EOC_VOLT so that a small current will not trigger
a false End-Of-Charge trigger. Thus, ClrFullyChrg is set at
about 90%. FULLY_CHARGED bit will be on until the battery
has discharged to less than 90%.
ClrFullyDischrg

255
10
Reset FULLY_DISCHARGED bit, 100 = 100%. Once fully
discharged bit is set, it will stay set until capacity rises above
this value, typically 10%.
EOCCurAvg

0
65535
200
EOC trigger for pulse charging. If the average current during
charging, with the CFET turned off, has dropped below the
AvgCurrEOCThresh threshold for a pass count equal to the
EEPROM parameter value ChrgCntrlTimr (typically
between 8 and 16), the End-Of-Charge state will be reached.
EOCRecheck
1
0
255
6
Delay filter for the EOC condition. Number of checks before
EOC trigger. The End-Of-Charge conditions must remain for
at least this number of periods before being considered true,
to help filter out false full conditions due to spikes.
EOCVolt
2
0
65535
4175
EOC trigger cell voltage. When any cell in the battery pack
reaches this voltage, the End-Of-Charge determination will
start monitoring the average current to determine when the
battery is full. When the average current is in the proper
range and the cell voltage is greater than EOC_VOLT, then
FULLY_CHARGED bit in BatteryStatus will be set and
terminate charge alarm will be active.
MaxTemp
1
0
65535
750
Maximum temperature measured (including external and
internal sensor). Coded value = (Celsius * 10 + 200)/4. This
is where the PS501 keeps track of the highest temperature it
has measured.
