Figure 6 : Optimized Charging Conditions

charging conditions, then the following calculations

apply :

Current Control :

R5 = V5 / Ich1 = 0.1 / 0.8 = 0.125

R5 = 125m

Ω

V5 = Vref x R3 / (R2 + R3) with R2 + R3 ~ 12k

Ω

and Vref = 1.24V

R3 = 1k

Ω,R2 = 11.4kΩ

V5 = R4 x Io + R5 x Ich2, therefore, R4 = (V5 - R5

x Ich2) / Io with Io = 1.4mA

R4 = 53.6

Ω

Vref = Vl x R15 / (R14 + R15) with Vl = 2.5V and

R14 + R15 ~ 20k

Ω

R15 = R14 = 10k

Ω

Voltage Control :

Vref = Vh x R6 / (R6 + R7) with Vh = 6.5V and

R6 + R7 ~ 12k

Ω

R6 = 2.36k

Ω, R7 = 10kΩ

Vref = Vh R17 / (R16 + R17)

R17 = 10k

Ω, R16 = 42kΩ
