A battery pack capable of inhibiting the occurrence of temperature deviations between battery cells in a battery cell stack includes a battery cell stack having a plurality of battery cells stacked in tight contact with each other; a heating member disposed along and in contact with three outer surfaces of the battery cell stack; a temperature sensor connected to each of the battery cells; and a battery pack case configured to receive the battery cell stack, the heating member, and the temperature sensors. The heating member has a structure including a first surface, a second surface, and a third surface.

Battery pack including heating member

The present invention relates to a relay control system and a control method thereof, and more particularly, to a relay control system and a control method thereof capable of determining whether an unrecoverable failure of a relay due to an unexpected environment, namely, whether the relay is fused, by measuring a voltage on a relay in real time while a battery unit operates in a secondary cell battery using DC power.

Relay control system and method for controlling same

Provided is a circuit for measuring insulation resistance, including: a first operational amplifier that is connected with a positive terminal of a battery and a second operational amplifier; a second operational amplifier that is connected with a negative terminal of the battery and the first operational amplifier; a first switch that is connected between the positive terminal and a non-inverting terminal of the first operational amplifier; and a second switch that is connected between the negative terminal and an inverting terminal of the second operational amplifier, wherein the first operational amplifier and the second operational amplifier are connected with each other through a ground.
