Example Embodiment

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples and with reference to the accompanying drawings. It should be noted that the directional terms mentioned in the examples, such as "upper", "lower", "middle", "left", "right", "front", "rear", etc., are only directions with reference to the drawings. Therefore, the directions used are only for illustration and not for limiting the protection scope of the present invention.

[0027] A highly reliable battery protection switch, such as Figure 2-4 As shown, it mainly consists of two parts: contact system and release device. The contact system is responsible for carrying the current in the circuit and switching the circuit when needed. The release device is responsible for the reliable maintenance of the state of the switch before switching, and the reliable release when need...

Abstract

The invention discloses a high-reliability battery protection switch. The high-reliability battery protection switch mainly comprises a contact system and a release apparatus; the contact system and the release apparatus adopt a spring contact finger contact mode for bearing a current in the circuit and performing circuit conversion in needing; the release apparatus adopts a structure of winding asliding block body with a blade spring, and is responsible for state reliable holding before the switch is switched and performing reliable releasing in needing, so as to enable the contact system tocomplete a circuit switching action; and the contact system and the release apparatus are connected together through a connecting rod. The high-reliability battery protection switch has the characteristics of high switching reliability and light overall weight.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a highly reliable battery protection switch. Background technique [0002] With the development of high technology, there are more and more electrical equipment on satellites, and the service life requirements are getting longer and longer, which puts forward stricter requirements on the energy density, long life and high reliability of satellite batteries. Because lithium-ion batteries have the advantages of small weight, high energy density, and long service life, more and more new satellites plan to use lithium-ion battery packs as power sources during launch and orbital shadow periods. Satellite lithium-ion battery packs are composed of multiple battery cells connected in series and in parallel. Although each battery cell has been strictly screened and matched, with the prolongation of service time and the increase of charge and discharge cycles, there are some performance p...
