Smart Battery Charger Specification
SBS Implementers Forum -Page 22- Revision 1.1
5 The charger is supplying “wake-up” charge to
the battery (from condition 1 above) AND
RES_HOT changes from 0 to 1.
The charger stops charging the battery. It
cannot “wake-up” charge again until it gets a
POR_RESET, AC is removed, or the battery is
removed. It can supply “controlled” charge to
the battery if the appropriate conditions are met
(see condition 8).
6 The charger is supplying “wake-up” charge to
the battery (from condition 2 above) and
RES_UR changes from 1 to 0.
The charger stops charging the battery. It
cannot “wake-up” charge again until it gets a
POR_RESET, AC is removed, or the battery is
removed. It can supply “controlled” charge to
the battery if the appropriate conditions are met
(see condition 9).
7 The charger is applying “wake-up” charge to
the battery AND INHIBIT_CHARGE is set to
1.
The charger stops charging the battery. The
timer continues to run. The charger can resume
“wake-up” charging if INHIBIT_CHARGE is
reset to 0 and RES_HOT = 0 or RES_HOT = 1
and RES_UR = 1.
8 The charger is applying “wake-up” charge to
the battery (or had been but has been stopped),
AND a ChargingCurrent() command is
received AND a ChargingVoltage() command
is received AND INHIBIT_CHARGE = 0
AND RES_HOT = 0.
The charger will supply “controlled” charge to
the battery as specified in the Current and
Voltage commands.
9 The charger is applying “wake-up” charge to
the battery (or had been but has been stopped),
AND a ChargingCurrent() command is
received AND a ChargingVoltage() command
is received AND INHIBIT_CHARGE = 0
AND RES_HOT = 1 and RES_UR = 1.
The charger will supply “controlled” charge to
the battery as specified in the Current and
Voltage commands.
10 The charger is supplying “controlled” charge
AND no new ChargingCurrent() or
ChargingVoltage() command is received for a
time-out period (140-210 seconds)..
The charger stops charging the battery. It can
resume “controlled” charging when conditions
8 or 9 are satisfied.
11 The charger is supplying “controlled” charge
to the battery AND an AlarmWarning()
message is received with any bit in the upper
nibble set.
The charger stops charging the battery. It can
resume “controlled” charging when conditions
8 or 9 are satisfied.
12 The charger is supplying “controlled” charge
to the battery (from condition 8 above) AND
RES_HOT changes from 0 to 1.
The charger stops charging the battery. It can
resume “controlled” charging when condition 8
is satisfied.
13 The charger is supplying “controlled” charge
to the battery (from condition 9 above) AND
RES_UR changes from 1 to 0.
The charger stops charging the battery. It can
resume “controlled” charging when condition 9
is satisfied.
14 The charger is supplying “controlled” charge
to the battery and INHIBIT_CHARGE is set
to 1.
The charger stops charging the battery, but
continues to accept new ChargingCurrent() and
ChargingVoltage() commands, continues to
monitor the battery Safety Signal input, and
continues to track the communications time-
out. It can resume charging the battery if
INHIBIT_CHARGE is cleared to 0, possibly at
difference current and voltage is new
commands have been sent in the interim.
15 The charger is in any state and it detects no
battery present (RES_OR = 1) OR AC not
present OR a 1 is written to POR_RESET.
The charger returns to its power-on reset
default state.
