Drawings
Fig. 1 is a partial perspective view showing a thermistor assembly and a battery using the same according to an embodiment of the present invention.
Fig. 2 is a diagram showing a battery pack using the thermistor assembly of the present invention.
Detailed Description
Provided is an implementation mode.
Hereinafter, a thermistor assembly according to an embodiment of the present invention and a battery using the same will be described with reference to fig. 1.
As shown in fig. 1, the embodiment of the present invention shows a battery 2 and a thermistor assembly 3, and the thermistor assembly 3 is attached to the outer surface of the battery 2 to detect a temperature change of the battery.
The thermistor assembly 3 includes a thermistor 4 and battery connecting parts 5, 5', and the thermistor 4 is in the form of a square sheet and is composed of a chip and a resin covering the chip. The battery connecting portion 5 is a tab extending from opposite sides of the thermistor 4, and the tab has a width and thickness smaller than those of the thermistor 4, and is preferably made of metallic nickel. The connecting portions 5, 5' are connected to the thermistor by resin coating.
As shown in fig. 1, the battery connecting portion 5 on one side of the thermistor 4 is connected to a lead wire 7, and is further electrically connected to the positive electrode of the battery through the lead wire 7. The battery connecting portion 5' on the other side of the thermistor 4 is connected to a terminal plate 6 of the battery, and is further electrically connected to the negative electrode of the battery through the terminal plate 6. The lead wire 7 and the terminal piece 6 are connected to the battery connecting portions 5 and 5' by resistance welding or soldering.
In addition, the thermistor assembly may also be used in a battery pack. As shown in fig. 2, the battery pack 11 is formed by connecting six batteries in series. The battery connecting portion on one side of the thermistor assembly 3 is connected to the negative electrode of the battery pack via the terminal piece 6, and the battery connecting portion on the other side is connected to the lead wire 7. The lead wire 7 is connected to the connector 10 in common with the positive lead wire of the battery pack.
Technical effects of the embodiments
According to the thermistor 4 of the embodiment, the thermistor 4 is a thermosensitive sensing component, and is coated with a resin and formed into a square sheet shape. The contact area with the battery 2 is larger, so the battery can be tightly attached to the surface of the battery, the assembly is convenient, the occupied space is small, and the battery is not easy to fall off due to collision and the like.
According to the thermistor assembly 3 of the embodiment, since the thermistor assembly 3 includes the thermistor 4 and the battery connecting parts 5, 5 'electrically connected to opposite ends of the thermistor and having conductivity, the thermistor assembly 3 can be fixed to the battery by connecting the battery connecting parts 5, 5' to the battery without separately fixing the thermistor assembly 3 to the battery using silicone, adhesive tape, or the like, which saves processes and materials. In addition, by forming the battery connecting portions 5 and 5' from the sheet-like connecting pieces, the contact surface between the battery connecting portion and the lead wire or the terminal of the battery can be increased, and the welding process can be facilitated.
According to the battery pack of the embodiment, the sheet-like battery connecting portions 5 and 5' of the thermistor assembly 3 having the square sheet-like thermistor 4 are electrically connected to the lead wire 7 or the terminal 6 by spot welding, and the battery pack has advantages of easy assembly, small space occupation, and difficulty in detachment of the thermistor.
Modification example
While various embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various combinations and modifications can be made within the scope not departing from the gist of the present invention.
For example, in the battery pack of the embodiment, the battery connecting portion 5 on one side of the thermistor 4 is connected to the lead wire 7 and is further electrically connected to the positive electrode of the battery via the lead wire 7, and the battery connecting portion 5' on the other side of the thermistor 4 is connected to the negative electrode of the battery via the terminal piece 6 of the battery. However, it is also possible to use a lead wire on both sides of the thermistor 4 without using a terminal piece, and to connect the battery connecting portions 5, 5' on both sides of the thermistor 4 to the positive and negative electrodes of the battery through lead wires, respectively; alternatively, terminal pieces may be used on both sides of the thermistor 4 without using wires, so that the battery connecting portions 5, 5' on both sides of the thermistor 4 are connected to the positive and negative electrodes of the battery through terminals, respectively; alternatively, the sheet-shaped battery connecting portions 5 and 5' may be bent without using lead wires or terminal pieces to be directly connected to the positive and negative electrodes of the battery.
