PS810

RemCap

mAh

440

The initial capacity of the battery. When the PS810 is first

powered up and initialized, before a learning cycle takes

place to learn the full capacity, the full capacity will take the

value programmed into RemCap to compute relative

State-Of-Charge percentage.

RemCapDelta

1/4 mAh

Maximum change in remaining capacity per measurement

period.

RLCycles

integer

The number of initial cycles without a relearn limit. The initial

number of cycles where the relearn limit is not active.

Normally, full charge capacity will change by a maximum of

256 mAh when relearned. Since FullCapacity can vary

greatly with the first learning cycle, the initial capacity may

not be correct; thus, this should be set to at least 2.

SerialNumber

integer

–

Battery data value for SerialNumber. The serial number of

the battery pack can be programmed here and retrieved with

the battery data SerialNumber command.

SleepVoltage

2700

The pack voltage at which the PS810 will enter Low-Voltage

Sleep mode.

StableCurr

EOC trigger current deviation level. In order to prevent cur-

rent spikes from causing a premature taper current trigger,

the average current and the instantaneous current must be

within StableCurr of each other for the End-Of-Charge to

trigger on the taper current.

TaperCRate

1/64 C

Upper limit EOC taper current, 64 = 1C.

TaperLow

1/64 C

Lower limit EOC taper current, 64 = 1C.

UserDataLen

bytes

Number of bytes read by UserData SMBus command.

VEODCoin

2500

Empty voltage of coin cell.

VEODOffset

2700

Base voltage for VEOD look-up table.
