ChFlags - EEprom Locations 0x80;
Description:
ChFlags is a set of bit flags that enable/disable charging and power supply functions.
Purpose:
ChFlags allows the Host to configure the HESC-SER to the type of battery pack, and system it is installed into.
Table 10, ChFlags bit map
Bit# Bit Name
Description
0
BattAutoStartEn* Charging is to autostart when the HESC-SER is reset, main power is removed then re-
applied, or when a new battery is inserted. 1 = enable, 0 = disable
1
TermEn*
Charge termination is enabled when TermEn is set. 1 = enable, 0 = disable
2
SMBactiveEn
The HESC-SER to function as a level 3 SMBus charger. 1 = enable, 0 = disable
SMBus timing in effect when SMBactiveEn = 1
3
IgnHiOffEn
When IgnHiOff is set, the HESC-SER will begin shutdown procedures when the IGN pin is
high. If IgnHiOff is low, the HESC-SER will begin shutdown procedures when the IGN pin is
low. The shutdown procedure will finish once shutdown is started.
4
BattIsolateEn*
The HESC-SER de-activates the battery enable line (BE) after the power supply enters the
shutdown mode.
5
SDserHiLo
Define polarity of SD (shut down) line on RS232 connector
SDser = 0; SD RS232 input transitioning from +5V to -5V generates shut down request.
SDser = 1; SD RS232 input transitioning from -5V to +5V generates shut down request.
6
Then*
Thermistor monitoring select, 1 = enable, 0 = disable
7
SUreq
Startup request when power applied when HESC-SER is hard-off**, 1 = off, 0 = on
•
For standard battery packs only (ie. Not for SMBus battery packs)
18.
BattLowVoltageDef – EEprom Locations 0x82
Description:
When the battery voltage drops below BattLowVoltageDef a Shut-Down is requested if the power supply outputs are
energized. The shut down will occur in
BATTSDDef seconds. Setting
BattLowVoltageDef to zero prevents any possible
shut down due to low battery voltage.
Purpose:
Allow time for the Operating System to shut down before the battery is fully discharged or damaged.
19.
BattLowCapacityDef – EEprom Locations 0x82
Description:
When the battery capacity drops below BattLowCapDef a Shut-Down is requested if the power supply outputs are
energized. The shut down will occur in
BATTSDDef seconds. Setting
BattLowCapDef to zero prevents any possible shut
down due to low battery capacity.
Purpose:
Allow time for the Operating System to shut down before the battery is fully discharged or damaged.
20.
BattTempMinDef - EEprom Locations 0x8A:
Description:
When BattTempMinEn is enabled, the HESC-SER will not charge a standard battery pack when the temperature is
below BattTempMinDef degrees.
Purpose:
Prevent damage to batteries that can occur when being charged at low temperatures.
