Minimum charging current for permanent
LED display. Since permanent LED display
requires current draw from the battery,
LEDs can be set to be on only while the
battery is charging, with a minimum current
of LEDPermMin.
Duration of LED display. When LEDs are
set up to display state-of-charge
information, they will be illuminated when
the switch is pushed. They will stay
illuminated for 2 seconds plus NLED *
period. For NLED = 8, period = 0.5, the
LEDs will stay on for 2 + 8 * .5 seconds, or
2 + 4 = 6 seconds.
Delay filter for all current safety conditions.
The safety conditions must be valid for
NSafeI * period to avoid false triggers due
to spikes or noise.
Delay filter for all cell voltage safety
conditions. The cell voltage based safety
conditions must be valid for NSafeV *
period to avoid false triggers due to spikes
or noise.
Maximum cell voltage difference reset
condition.
Maximum temperature reset condition.
Maximum current reset condition.
Maximum cell voltage reset condition.
Maximum pack voltage reset condition.
Minimum temperature reset condition.
Minimum cell voltage reset condition.
Terminate Charge Alarm reset condition.
Safety condition of maximum cell voltage
difference.
Safety condition of maximum charging
current.
Safety condition of maximum discharging
current.
Safety condition of maximum temperature
(Celsius*10+200).
Safety condition of maximum cell voltage.
Safety condition of maximum pack voltage.
Safety condition of minimum temperature
(Celsius*10+200).
Safety conditions of minimum cell voltage.
