The present invention comprises: a laminator electrically connected to a power control unit, and including multiple battery cells (30); a locking unit including metal bands (81, 83), extending from an end of the laminator to the other end thereof and electrically grounded, and locking the laminator; a voltage sensor installed in at least one battery cell (30) among the multiple battery cells (30), and detecting a voltage of the battery cell (30); first wires (34A, 34B) connected to the voltage sensor, and extending in a laminating direction of the battery cell (30); a temperature sensor, measuring the temperature of the laminator, or a current sensor measuring a current flowing into and out of the laminator; and first wires (37, 38) connected to the temperature sensor or current sensor, and extending in the laminating direction. A voltage, lower than that of the first wires (34A, 34B), is applied to the first wires (37, 38), and the metal bands (81, 83) are placed between the first wires (34A, 34B) and the first wires (37, 38). Therefore, the present invention is capable of preventing noise from diffusing to the wires. |
