The present invention provides a battery charge/discharge control device including a contactor driver which is on/off controlled according to AN output signal of a micro control unit (MCU), a contactor coil through which current flows according to an on/off state of the contactor driver, and whose one end is electrically connected to the contactor driver and the other end is electrically connected to a power source, and a contactor which is turned on by the current flowing through the contactor coil so as to perform charging and discharging of the battery.

Battery charge/discharge control device and battery management device

The present invention relates to an apparatus and a method capable of calculating insulation resistances and parasitic capacitances of a battery outside the battery. In the present invention, when a positive electrode connector and a negative electrode connector are coupled to a positive electrode terminal and a negative electrode terminal of the battery, respectively, and a ground connector is coupled to a case of the battery, even though the battery is positioned inside a chamber in order to perform a temperature test or the like of the battery, the insulation resistances and the parasitic capacitances of the battery may be calculated without needing to move the battery to the outside of the chamber. Accordingly, the insulation resistances and the parasitic capacitances of the battery may be conveniently calculated.
