5.1 Basic Lead-Acid Battery Parameters
Principles
Battery management includes battery boost charging and float charging management,
discharge detection and capacity detection, etc. This management is performed based on the
basic battery parameters. Therefore, configure these basic parameters as required to ensure the
normal battery management.
Parameters
Table 5-1 Basic battery parameters
Parameters
Description
Batt String
If no battery is connected, set Batt String to 0.
If one or more battery strings are connected, set Batt String to 1.
Capacity
Equals to the total capacity of all connected batteries.
Charge Coef
The maximum charging current of the battery is determined by the
charge coefficient multiplied by battery capacity.
Examples:
If the battery capacity is 100 Ah and the maximum charging current is
10 A, set the charge coefficient to 0.10.
