7.3 Battery Usage History (only for BMW
vehicles)
The Battery usage history function will display the following three tests:
1. SOC (State of Charge) in the last 5 days: monitors the SOC status and
diagnoses the health status of the battery.
2. Proportion of SOC duration: displays battery usage habits of drivers.
3. Estimated current mileage comparison (battery replacement):
determines the current battery life based on the previous vehicle mileage
record.
All three test screens are comprised of three sections:
1. Main view: displays data in a waveform or bar graph.
2. Data description: provides brief descriptions of the test result.
3. Suggestion: offers suggestions on existing problems.
