The present invention relates to a battery, and more particularly to a battery, a method of manufacturing the battery, and a battery system.

Generally, batteries are widely used for power supply of electronic devices. Figure 1 is a block diagram of a battery in the prior art. As shown in FIG. 1, battery 102 includes a plurality of battery cells 104_1-104_5 that are isolated by a separator. After the battery 102 is sealed, the positive and negative electrodes of the battery 102 may protrude outside of the battery 102. The state of the battery 102 can be detected through the positive and negative electrodes of the battery 102. However, when the user wants to detect the state of the internal battery cells 104_1-104_5, since the battery 102 is sealed and only the positive and negative electrodes of the battery 102 protrude from the outside of the battery 102, the user needs to drill a hole in the corresponding position of the battery 102. , the external detection unit is coupled to the internal battery unit. However, this method has many drawbacks.

First, impurities may invade the interior of the battery 102 through the holes, thereby affecting the performance of the battery 102. Second, the coupling of the detecting unit to the internal battery unit is unstable. As a result, the detecting unit cannot remain coupled to the internal battery unit.

Third, since 104_1-104_5 has an electrolyte, if the position of the user's hole is not accurate enough, the hole in the battery unit may leak the electrolyte, thereby damaging the battery.

Compared with the prior art, the battery of the present invention, the method of manufacturing the battery, and the battery system can detect the state of the internal battery unit without additional drilling on the battery. In this way, the integrity of the battery is maintained and the battery is protected from impurities.

The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments to make the features and advantages of the present invention more obvious.

A detailed description of the embodiments of the present invention will be given below. While the invention will be described in conjunction with the embodiments, it is understood that the invention is not limited to the embodiments. Rather, the invention is to cover various modifications, equivalents, and equivalents of the invention as defined by the scope of the appended claims.

In addition, in the following detailed description of the embodiments of the invention However, it will be understood by those of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail in order to facilitate the invention.

In one embodiment, the present invention discloses a battery having an embedded detection unit. The battery includes a plurality of battery cells that are isolated by the isolation plate and connected in series via the power rod. A plurality of detecting units are coupled to the plurality of battery units to detect a state of the battery unit. After the battery is sealed, the detection unit is embedded in the battery, and the result of the detection unit is output through a plurality of interfaces outside the battery. The advantage is that the user can detect the status of the internal battery unit without drilling the battery. In this way, the integrity of the battery is maintained and no impurities are introduced into the battery.

2A is a block diagram of a battery 202A including an embedded detection unit, in accordance with an embodiment of the present invention. Battery 202A includes a plurality of battery cells (not shown in Figure 2A) that are isolated by a spacer. After the battery 202A is sealed, a plurality of interfaces (eg, multiple pins of the coupler 208 and the positive and negative electrodes 206 and 206 of the battery 202A) are located on the surface of the battery 202A. In an embodiment, coupler 208, positive electrode 204, and negative electrode 206 are located on the top panel of battery 202A.

In an embodiment, a plurality of detection units are embedded in the battery 202A to detect the state of the internal battery unit. The pins of the coupler 208 are coupled to the embedded detection unit, and each pin is coupled to a detection unit. Prior to sealing of the battery 202A, circuitry is provided within the battery 202A that is coupled to the embedded sensing unit such that after the battery 202A is sealed, the circuit is embedded in the battery 202A. In this way, the battery management unit monitors the status of the internal battery unit through the pins and takes predetermined measures according to the status. For example, if the battery management unit detects an abnormal state of the battery unit, for example, the voltage of the internal battery unit is above a predetermined threshold, the battery management unit takes protective measures.

An advantage is that when the battery 202A is used, the embedded detecting unit detects the state of the battery unit in the battery 202A, and the detection result is output via the coupler 208. As a result, the user does not need to drill the battery 202A to install an external detecting unit. Therefore, the integrity of the battery 202A is maintained without drilling, and thus the battery 202A is not introduced with impurities. Moreover, since the user does not need to install additional components on the battery 202A, the size and shape of the battery 202A need not be changed. In this way, the battery 202A can be used in an application system of the prior art without changing the application system. Therefore, the designer can design a similar mounting device that mounts the battery 202A into various application systems.

Moreover, the coupler 208 further includes a pin that is coupled to the positive pole 204 and the negative pole 206 of the battery 202A.

As such, the battery management unit also monitors the status of the battery 202A via the coupler 208. The advantage is that the circuit that couples the battery management unit to the positive electrode 204 and the negative electrode 206 is omitted, thereby reducing cost and size.

In another embodiment, the coupler 208 is located anywhere outside of the battery 202B, as shown in Figure 2B. After the battery 202B is sealed, the cable 210 extends from the battery 202B where a plurality of wires are arranged side by side, coupled to each other, entangled or braided to form a single device. In the battery 202B, the wires of the cable 210 are isolated from each other and coupled to the embedded detection unit to transmit information indicative of the state of the internal battery unit. Prior to sealing of the battery 202B, the wires in the configuration cable 210 are coupled to circuitry embedded in the detection unit. As such, after the battery 202B is sealed, the circuit is embedded in the battery 202B. The coupler 208 is coupled to one end of the cable 210 external to the battery 202B.

Moreover, the wires in the cable 210 are coupled to the positive electrode 204 and the negative electrode 206 of the battery 202B to transmit information indicative of the state of the battery 202B. In this way, the coupler 208 receives the data through the corresponding pin and outputs the data.

The advantage is that the position of the coupler 208 is more flexible, eliminating the need to install the battery 202B. Moreover, the shape of the battery 202B is simpler, thereby simplifying the design of the mounting device for mounting the battery 202B into the application system.

Similarly, the corresponding electric lever is coupled between the battery cells 304_2 and 304_3, 304_3 and 304_4, 304_4 and 304_5, and the adjacent electric plates of 304_5 and 304_6, and further, the battery cells 304_- and 304_6 are connected in series.

Moreover, a plurality of detecting units are coupled to the battery units 304_1-304_6 to detect the states of the battery units 304_1-304_6. In an embodiment, an electric bar (eg, metal bar) 310_1 is partially embedded in the motorized lever 308_1 to detect the state of the battery cells 304_1 and 304_2, for example, the negative voltage of the battery cell 304_1 and the positive voltage of the battery cell 304_2.

Figure 3B shows how a detection unit can be embedded in a battery in accordance with an embodiment of the present invention. In the example of FIG. 3B, the electrical housing 308_1' of the electric lever 308_1 is coupled between the electrical boards 306_2 and 306_3. The top surface of the electric casing 308_1' has a hole. The diameter of the hole is larger than the diameter of the electric bar 310_1. The electric rod 310_1 is inserted through the hole portion into the electric casing 308_1' for a period of time during which a liquid metal such as liquid lead is injected into the gap between the through hole and the electric rod 310_1 until the liquid lead fills the electric shell 308_1'. As a result, when the liquid lead becomes solid, the electric rod 308_1 is formed, and the electric rod 310_1 is firmly mounted on the electric rod 308_1.

Also, referring to FIG. 3A, the electric bars 310_2-310_5 are partially embedded in the electric lever, respectively, to detect the state of the battery cells 304_2-304_6. Moreover, the electric bars as the positive electrode 204 and the negative electrode 206 are fixed on the positive electrode plate 306_1 of the battery unit 304_1 and the negative electrode plate 306_4 of the battery unit 304_6 to detect the positive voltage and the negative voltage of the battery 302. Therefore, the circuit board is coupled to the battery cells 304_1-304_6 via the electric bars 310_1-310_5 (in FIG. 3A), the positive electrode 204, and the negative electrode 206.
