Embodiment Construction

[0015] Hereinafter, embodiments of the present disclosure will be described as follows with reference to the accompanying drawings.

[0016] However, this disclosure may be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0017] Throughout the specification, it will be understood that when an element such as a layer, region or wafer (substrate) is referred to as being "on," "connected to" or "coupled to" another element, it may be Is directly on, "connected to" or "coupled to" another element or there are other elements intervening therebetween. In contrast, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another element, there may be no other intervening elements or layers present...

Abstract

The invention relates to a battery safety apparatus. The battery safety apparatus includes a first switch of which one end is electrically connected to a battery and in which an open-closed state is determined depending on temperature; and a second switch electrically connected to the first switch in parallel and in which an open-closed state is determined depending on temperature, wherein an open-closed state threshold temperature of the first switch is different from an open-closed state threshold temperature of the second switch.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2016-0173392 filed with the Korean Intellectual Property Office on December 19, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to a battery safety device. Background technique [0004] Recently, plug-in hybrid electric vehicles (PHEVs), electric vehicles (EVs), and the like have gained high public visibility due to consideration of the importance of the traffic environment. For PHEVs and EVs, the technological development of batteries is considered to be very important. This is because the capacity and output of this battery should be significantly higher than other environmentally friendly vehicles. However, an excessive increase in the capacity and output of the battery may have an adverse effect on the safety of the battery. [0005] In addition, t...
