Patent ID: 11921165
Assignee: SK ON CO., LTD.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC G  H  Y | IPC G  H

Claim 6:
7. The method for calculating characteristics of a battery of claim 4, wherein the method for obtaining the value output from the second ADC in a state in which only the second switch is turned on uses the following equation:

Visop=Vb×[(R2+R1)∥Risop]/[[(R2+R1)∥Risop]+Rison]

wherein:
Visop refers to a positive electrode insulation voltage value from the second ADC in a state in which only the second switch is turned on;
R1 refers to the resistance value of the third resistor;
R2 refers to the resistance value of the fourth resistor; and
Risop and Rison refer to the insulation resistances of the battery.
