The content of the final part of the strings depends on the string type. Processing
strings (Code 250) contain two additional fields:
• Battery data. This field displays four different data elements, in this order:
Process or status. This number represents the process or status of the current
program as listed in Appendix A, Messages and Warnings (see By Code).
Voltage. This is the terminal voltage of the battery in mV.
Current. This is the charge or discharge current being applied to the battery in mA.
If the current number is positive, the battery is being charged; if it is negative, the
battery is being discharged.
Battery temperature. This is battery temperature in degrees Celsius. If
temperature sensing is disabled in the C-code, this value is always 0.
Back-slash characters separate the four elements.
• Battery capacity. In most cases, this field displays the current (or most recent)
battery capacity and the previous battery capacity, both as percentages of the
nominal battery capacity in the C-code. A back-slash character separates the
two capacities. Current battery capacity is updated (increased) during
discharge cycles.
Note If running QuickTest, this field displays the battery SoH (State-of-health) as
a percentage, followed by the ASCII value of the confidence grade for the matrix (A
= 65, B = 66, C = 67).
The bottom text string in Figure 9 is a processing string. It indicates that the battery
in station 1 (ID CDX0095468) is processing normally (event 250), charging
(process 2) with a terminal voltage of 1345mV, a charge current of 801mA, and a
battery temperature of 28°C. The most recent battery capacity achieved was 74%;
the previous capacity was 68%.
Event strings contain one or two fields in addition to the first six:
