Claim 1:
2. The method for calculating characteristics of a battery of claim 1, wherein the apparatus for calculating characteristics of a battery further includes a seventh resistor having one end coupled to the positive electrode connector, one end of the first resistor, and one end of the third resistor, an eighth resistor having one end coupled to the negative electrode connector, one end of the second resistor, and one end of the fifth resistor and a fourth switch, and
the method for calculating characteristics of a battery further comprises, after the calculating of the insulation resistances of the battery:
controlling, by the control unit, only the fourth switch having one end coupled to the other end of the seventh resistor and the other end of the eighth resistor and the other end coupled to the ground connector, one end of the fourth resistor, and one end of the sixth resistor to be turned on;
controlling, by the control unit, the second switch to be turned on for a preset time in a state in which the fourth switch is turned on;
obtaining, by the control unit, a value output for a preset time from the second ADC in a state in which only the second switch and the fourth switch are turned on; and
calculating, by, the control unit, a positive electrode parasitic capacitance of the battery by using the voltage of the battery calculated, the insulation resistances of the battery, and the value output for a preset time from the second ADC in the state in which only the second switch and the fourth switch are turned on.
