Time in the charge range

The power module calculates and stores the

• Charge condition
  
• and the time
  

of the battery with the relevant charge.

The charge ranges of the battery are displayed in the following increments:

• 0-10%
  
• 10-20%
  
• 20-30%
  
• 30-40%
  
• 40-50%
  
• 50-60%
  
• 60-70%
  
• 70-80%
  
• 80-90%
  
• 90-100%
  

The time the battery spends in each charge range is displayed in hours.

During normal driving, the battery should spend the longest period in the charge range above 60%.

A higher proportion of dwelling time in low charge ranges around 10% - 40% can have the following causes:

• Poor driving cycle with greater discharge than charge
  
• Frequent operation of auxiliary consumer units: telephone, independent heating, etc.
  
• Frequent operation of sidelights, parking lights, hazard warning lights. In the case of legally prescribed consumer units, the power module does not shut down the vehicle electrical system. Complete discharge of the battery is possible.
  
• Increased standby current (fault code memory entry present)
  
• Defective alternator
