Battery Management
To maintain the battery in a good state of health, an intelligently controlled
charging algorithm is used. The purpose is to ensure that the correct voltages are
applied to the battery terminals at the appropriate times throughout it’s usage
cycle.
To prevent corrosion on the battery positive plate due to continuous float charging
current (VFloat = 13.65V), the unit utilises a storage mode voltage (VStore =
13.25V) when no activity on the battery is detected. This extends the battery life.
During store mode, the unit exits to boost mode (VBoost = 14.05V) for 15 minutes
every 24hrs to maintain charge in the battery. If battery activity is detected during
store mode it exits automatically into float mode.
