TABLE 4-1:

V_EOD LOOK-UP TABLE

The above table is an example of the various voltage

values that will signal the shutdown points as a function

of temperature and discharge rate.

Also shown is the amount of capacity left after

shutdown that will compensate RSOC.

Table 4-2 shows the actual names of the values in the

EEPROM.

TEOD 8 coded bytes

typ: 5, 20, 35, 50, 80, 113, 150, 150

Range: 1-255 per byte

EOD Temperature boundaries, 8 increasing values of temperature coded as TEODx = (Tcelsius * 10 + 200)/4

CEOD 8 coded bytes

typ: 19, 32, 48, 64, 77, 90, 109,1 09

Range: 1-255

EOC C-rate boundaries, 8 increasing values of C-rates coded:

CEODx = C-rate * (256/28/RF), where RF is the Rate Factor (RFACTOR) OTP EPROM parameter.

For RF = 7, CEODx = C-rate * 64. Thus, a value of 32 is one-half C, etc.

FCCP coded %

typ: 50, 25, 12, 8, 0, 0, 0

Range: 1-255

Unusable residual capacity before save to disk, corresponding to temperature, 255 = 100%

VEOD coded

typ: 75

Range: 1-255

End-Of-Discharge voltage, voltage = 2700 + 4 * VEOD. Cell voltage at which save to disk is signaled.
