DeviceChemistry( ) (0x22)
Description:
This function returns a character string that contains the battery chemistry. For example, if the
DeviceChemistry( ) function returns
NiMH
, the battery pack contains nickel metal hydride cells. The bq2083V1P2
sets DeviceChemistry( ) to the value programmed in
Device Chemistry Length
DF 0x220x26.
Purpose:
The DeviceChemistry( ) function gives cell chemistry information for use by charging systems. The
bq2083V1P2 does not use DeviceChemisty( ) values for internal charge control or fuel gauging.
SMBus protocol:
Read block
Output:
String
character string with maximum
length of 4 characters (4 + length byte).
The following is a partial list of chemistries and their expected abbreviations. These abbreviations are
not
case
sensitive.
Lead acid
Lithium ion
Nickel cadmium
Nickel metal hydride
Nickel zinc
Rechargeable alkaline-manganese
Zinc air
PbAc
LION
NiCd
NiMH
NiZn
RAM
ZnAr
The ManufacturerData( ) (0x23)
Description:
This function allows access to the manufacturer data contained in the battery (data). The
bq2083V1P2 stores seven critical operating parameters in this data area.
Purpose:
The ManufacturerData( ) function may be used to access the manufacturer’s data area. The data fields
of this command reflect the programming of eight critical data flash locations and can be used to facilitate
evaluation of the bq2083V1P2 under various programming sets. The ManufacturerData( ) function returns the
following information in order:
Pack Configuration, Gauge Configuration, Misc Configuration, Digital Filter, Self
Discharge Rate, Pack Load Estimate, Battery Low%, and Near Full
(2 bytes) AFE Status, and the pending EDV
threshold voltage (low byte and high byte).
SMBus protocol:
Read block
Output:
Block data
data that reflects data flash programming as assigned by the manufacturer with maximum
length of 13 characters (12 + length byte).
Pack Status and Pack Configuration (0x2f)
This function returns the pack status and pack configuration registers. The pack status register contains a number
of status bits relating to bq2083V1P2 operation. The pack status register is the least significant byte of the word.
The pack configuration register reflects how the bq2083V1P2 is configured as defined by the value programmed
in
Pack Configuration
in DF 0x28.
The pack status register consists of the following bits:
b7
AFE
b6
b5
SS
b4
VDQ
b3
0
b2
SOV
b1
b0
EDV2
CVOV
CVUV
AFE
The AFE bit indicates whether the bq29311 RAM integrity check has failed.
0
bq29311 integrity check passed
1
bq29311 integrity check failed
