The present invention relates to a battery system for detecting a damaged battery cell, and a method of evaluating a battery module. The battery system and the apparatus for evaluating performance of the battery module can accurately predict the location of the battery cell where gas has been generated by introducing a plurality of gas sensor units in the battery module where a plurality of battery cells are accommodated, and comparing gas detection time points measured in the gas sensor units when gas is generated in a battery cell. Hence, the battery system and the apparatus for evaluating performance of the battery module can be usefully used in terms of development of a battery module and/or management of a developed battery module.

Battery system and battery module evaluation method capable of detecting damaged battery cell

The present invention provides a battery safety test device includes: a mechanical switch element having one end connected to either a battery positive or negative electrode and the other end connected to an electronic switching element; the electronic switching element having one end connected to the mechanical switch element and the other end connected to the other of the battery positive or negative electrode; a voltage sensor for measuring a voltage of the battery after the mechanical switch element and the electronic switching element are turned on; and a current sensor for measuring a current of the battery after the mechanical switch element and the electronic switching element are turned on.

Battery safety test device and method

Provided is a scroll compressor which has a reduced noise vibration by minimizing an impact sound generated when the operation of the scroll compressor is stopped.

Scroll compressor

Scroll compressor includes a shaft rotatably supported to a casing; an eccentric bush having a recess part into which one end portion of the shaft is inserted, an eccentric part eccentric to the shaft, and a balance weight disposed at the opposite side of the eccentric part with respect to the recess part; an orbiting scroll for performing the orbiting motion in interlock with the eccentric part; and a fixed scroll for forming a compression chamber together with the orbiting scroll. The casing has an orbiting groove in which the eccentric bush performs the orbiting motion, a buffer member is interposed between the orbiting groove and the balance weight. Rotation clearance is formed between the recess part and the shaft. The buffer member is compressed between the balance weight and the orbiting groove before the recess part and the shaft contact each other by the rotation clearance.

A scroll compressor that includes a rotating shaft, an eccentric bush having a recess, into which one end of the shaft is inserted, and an eccentric portion eccentric to the shaft, an orbiting scroll operatively connected to the eccentric portion for orbiting, a fixed scroll engaged with the orbiting scroll, and a buffer member interposed between the one end of the shaft and the recess. Therefore, it is possible to prevent damage to the scrolls due to liquid refrigerant compression during initial operation and to prevent an impact sound between the shaft and the eccentric bush due to the rotational clearance therebetween.

Disclosed herein is a compressor that includes a casing, a fastening part disposed at a portion corresponding to a support bracket provided in a compressor mounting part of a vehicle on the casing, and a fastener connecting the support bracket to the fastening part, wherein a compressor's center of gravity and a compressor's point of support supported by the fastener are positioned in a longitudinal direction of the fastener. The present disclosure has an effect of relieving rotational moment and fatigue stress occurring in the compressor when the compressor is mounted to the vehicle.

Compressor for vehicle

Disclosed herein may be an electric compressor. The electric compressor may include: a rear housing having a discharge chamber into which refrigerant is discharged; and an oil separator disposed in the discharge chamber and having a refrigerant inlet hole through which the refrigerant is drawn into the oil separator. The discharge chamber may protrude in a multi-stepped manner outwards from the rear housing such that a volume of the rear housing is increased, and based on the oil separator, an internal space of the discharge chamber may be divided into spaces having different volumes.

Compressor for vehicles

The present invention relates to a vane rotary compressor wherein the volume of a compression room is reduced and a fluid is compressed when a rotor rotates. According to one embodiment of the present invention, the present invention provides the vane rotary compressor for maximizing the rotational moment of a vane by extending a weight part at a front end part of the curved blade type vane so as to remove the hitting noise due to the delay of the rotational operation of the vane when the rotor is rotated, and increasing the performance by reducing the internal leak.

Vane rotary compressor

Provided are a secondary battery, a battery module, and a battery pack, which have improved safety. Particularly, since a bulletproof material is disposed on the inside and/or the outside of an exterior part, even when a conductive needle-shaped member penetrates a secondary battery, heating, burning, discharge of evaporated electrolyte, and electrical contact between the needle-shaped member and an electrode can be prevented, thereby improving safety of the secondary battery, the battery module, and the battery pack.

Secondary battery having improved safety

The present invention relates to a vane rotary compressor in which, while a rotor is rotating, the volume of a compressing chamber is reduced and a fluid such as a refrigerant is compressed. The vane rotary compressor according to one embodiment of the present invention is provided with the compressing chamber, the inner circumferential surface of which is formed in the shape of an involute curve, wherein the rotor is hinge-coupled with a plurality of cantilever vanes such that compression efficiency is high and noise is prevented from occurring during the operation of the compressor.
