Problems solved by technology

In this case, the inner space of the battery pack is reduced and its structure is complicated in terms of preparing the fixing structure of the filter element
In addition, the wire is often wound at least once around the ferrite core filter, and in this case, the manufacturing process becomes complicated and the internal design becomes difficult

example 1

[0138] with figure 1 and 2 A battery pack was prepared in the same shape as shown. In addition, the battery pack connector for this battery pack is manufactured to have the same image 3 and 4 A power supply connection unit and a communication connection unit of substantially similar shape are shown. In particular, the power supply connection unit is prepared to include as Figure 4 The power supply cover and the power supply conductor of the power supply connection unit shown have a rectangular parallelepiped shape. Here, the power supply housing is manufactured to include ferrite material. Also, the overall size of the battery pack connector is prepared such that the width ( Figure 4 The length of the Y-axis direction), the length ( Figure 4 The length of the X-axis direction) and height ( Figure 4 The lengths in the Z-axis direction) are about 10 cm, 8 cm, and 4 cm, respectively. Also, the size of the power supply housing was prepared such that the width, length...

example 2

[0140] A battery pack was prepared with the same material and the same shape as the battery pack of Example 1 except for the shape of the power supply conductor. In particular, as Figure 4 and 5 As shown, the power supply conductors of the connector applied to the battery pack of Example 2 were bent twice in opposite directions inside the housing. Here, the length of the current supply conductor is about 22 cm.

Abstract

The present invention provides a battery pack connector which not only has a simple structure but also can effectively prevent noise from leaking into or from a battery pack. A battery pack accordingto the present invention includes a battery pack connector located on a pack case of the battery pack including a battery management system, wherein the battery pack connector comprises: a communication connecting unit configured to be connectable to a communication wire for transmitting / receiving information to / from the battery management system; and a power supply connecting unit which is configured to be connectable to a power supply wire for supplying operating power to the battery management system, and at least a portion of which contains a noise-blocking material.

Description

technical field [0001] This application claims priority from Korean Patent Application No. 10-2018-0018596 filed in Korea on February 14, 2018, the disclosure of which is incorporated herein by reference. [0002] The present disclosure relates to a battery pack connector, and more particularly, to a battery pack connector provided in a battery pack case of a battery pack and configured to be connected to an external device, including the battery pack connector battery packs, vehicles, etc. Background technique [0003] The current commercialized secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, lithium secondary batteries, etc. Among these secondary batteries, lithium secondary batteries hardly produce memory compared with nickel-based secondary batteries. effect, and thus have the advantages of free charge / discharge, very low self-discharge rate, and high energy density, and thus lithium secondary batteries are attract...
