Formula 1
The voltage drop U_R_I is the difference of U_28 V and U_BAT:
U_R_I = U_28 V – U_BAT
Formula 2
The current flow I_BAT can be calculated as follows:
Example 1 – Calculate series resistance
U_28 V = 28.9 V, U_BAT = 20 V, I_BAT = 10 A
The accumulator is discharged, and the State of Charge is 0%. For U_BAT in this case 20
V is assumed. The AC-DC converter supplies a voltage of 28.9 V. The maximum charge
current is set to 10 A. U_R_I is therefore 8.9 V.
Formula 2 is transformed to R_I and from the division U_R_I to I_BAT a resistance value
of 0.89 Ω results.
The following figures show the relationship between resistance R_I and current I_BAT
and the resulting power dissipation once for U_R_I = 9 V and U_R_I = 5 V.
