Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The battery 20 and the battery control system of the present invention will be described in detail below with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.
Example one
With reference to fig. 1 to 3, an embodiment of the present invention provides a battery 20, where the battery 20 may include a plurality of battery cells 21, a plurality of wires 22, and a plurality of fusing structures 24. Wherein a plurality of the battery cells 21 are connected in series. One end of each wire 22 is electrically connected with the positive electrode or the negative electrode of one of the battery cells 21, and the other end of each wire is provided with a first electrical connector 23, the first electrical connector 23 can be used for being electrically connected with an external module, and the external module is electrically connected with each battery cell 21 through the wires 22 and the first electrical connectors 23, so that the battery 20 can be charged through the external module or the working state of each battery cell 21 can be monitored. In this embodiment, the positive electrode and the negative electrode of each battery cell 21 are respectively led out through one lead 22, and the adjacent battery cells 21 share the same lead 22. Each of the battery cells 21 includes a positive electrode tab and a negative electrode tab, and one end of each of the wires 22 is electrically connected to the positive electrode tab or the negative electrode tab of the corresponding battery cell 21, so that the positive electrode and the negative electrode of each of the battery cells 21 are led out through the wires 22. The first electrical connector 23 may be an electrical socket or an electrical plug.
In the present embodiment, a fuse structure 24 is connected in series between the positive electrode of each cell 21 and the first electrical connection member 23 electrically connected to the positive electrode of the current cell 21, and between the negative electrode of each cell 21 and the first electrical connection member 23 electrically connected to the negative electrode of the current cell 21. When at least two first electrical connection members 23 are in direct electrical contact with each other, at least two first electrical connection members 23 in direct electrical contact with each other can be blown to interrupt the two first electrical connection members 23 in direct electrical contact with the corresponding battery cells 21, corresponding to the series-connected fuse structure 24. In the prior art, since the fusing structure 24 is not connected in series on the lead 22 leading out the positive and negative electrodes of each battery cell 21, the two first electrical connectors 23 are directly electrically connected, that is, the positive electrode and the negative electrode of the battery cell 21 are directly connected through the lead 22, so that the battery cell 21 is short-circuited and burned, and the safety of the battery 20 is poor. In the embodiment of the present invention, by providing the fusing structure 24 on each conducting wire 22, when the first electrical connection members 23 of at least two conducting wires 22 are in direct electrical contact, a large current flows through the conducting wires 22 in direct electrical contact, and the fusing structure 24 on the conducting wires 22 is blown, so that the risk of burning the corresponding battery cell 21 is avoided, and the safety of the battery 20 is greatly improved.
The reasons for making a direct electrical contact between at least two of said first electrical connectors 23 may include the following:
the first method comprises the following steps: since the first electrical connection member 23 is mostly a copper terminal, when the battery 20 is placed in a humid environment, particularly a salt fog environment, the copper terminal is easily corroded to cause direct contact between two adjacent copper terminals, thereby causing short circuit of the battery cell 21.
And the second method comprises the following steps: the first electrical connector 23 is plugged multiple times, causing the first electrical connector 23 to wear and thus short circuit.
And the third is that: when the user inserts or removes the plurality of first electrical connectors 23, at least two first electrical connectors 23 are deformed into contact by an excessive force, thereby causing a short circuit.
And fourthly: a user's misoperation such that two or more copper terminals are in direct contact may also cause the cell 21 to be short-circuited.
For example, in an embodiment, the fuse structure 24 is a portion of the corresponding lead 22, and the width of the fuse structure 24 is smaller than the width of the other portion of the corresponding lead 22, that is, the width of a portion of the lead 22 is smaller than the width of the other portion, when a large current flows through the lead 22, the area with the smaller width on the lead 22 is burned out, so as to separate the corresponding battery cell 21 from the electrical connection, and prevent the large current from flowing into the corresponding battery cell 21 and burning out the battery cell 21. It should be noted that the conditions to be satisfied by the width of the fuse structure 24 include: when the battery cell 21 is normally operated, the corresponding fusing structure 24 is not blown. When the battery cell 21 is short-circuited, the corresponding fuse structure 24 is blown. In addition, in the present embodiment, the width of the fusing structure 24 is designed in consideration of the strength of the conductive wires 22, so as to prevent the conductive wires 22 from being easily worn by external force. Further, in the present embodiment, the fusing structure 24 is disposed at a middle region of the corresponding conductive line 22. Preferably, the fusing structure 24 is close to the corresponding battery cell 21, that is, the length of the lead wire 22 from the head of the fusing structure 24 to the corresponding battery cell 21 is smaller than the length of the lead wire 22 from the fusing structure 24 to the corresponding first electrical connector 23.
In another embodiment, referring to FIG. 3, the fuse structure 24 is a resistor R with a predetermined resistance. In this embodiment, the resistance R needs to satisfy: when the battery cell 21 normally operates, the corresponding resistor R is not blown. When the battery cell 21 is short-circuited, the corresponding resistor R may be blown. Wherein the predetermined resistance is greater than or equal to 10m Ω (unit: milliohm) and less than or equal to 100m Ω. For example, the preset resistance values are 10m Ω, 20m Ω, 30m Ω, 40m Ω, 50m Ω, 60m Ω, 70m Ω, 80m Ω, 90m Ω, 100m Ω, and the like. The resistor R can be any type of resistor R in the prior art, and is preferably a fuse resistor. Because the safety resistor has the function of a common resistor under normal conditions, once the circuit fails and exceeds the rated power of the circuit, the circuit can be disconnected within a specified time, so that the effect of protecting other components is achieved, in the embodiment, when the battery cell 21 is in a short circuit, the safety resistor can be disconnected, and the battery cell 21 is protected. The fuse resistor may be of a repairable type or of a non-repairable type. Preferably, the fuse resistor is a repairable fuse resistor, and when the battery cell 21 returns to normal again, the fuse resistor automatically returns, and the battery cell 21 can continue to operate. In this embodiment, the battery 20 includes 6 battery cells 21, and the 6 battery cells 21 are connected in series, and the positive electrode and the negative electrode of each battery cell 21 are connected to the first electrical connector 23 through the resistor R, and two adjacent battery cells 21 share the same wire 22, that is, the positive electrodes and the negative electrodes of all the battery cells 21 can be monitored.
In yet another embodiment, the fuse structure 24 is a fuse. In this embodiment, the fuse should satisfy: when the battery cell 21 works normally, the corresponding fuse cannot be blown. When the battery cell 21 is short-circuited, the corresponding fuse is blown. Preferably, the wire 22 is electrically connected to one end of the fuse by a second electrical connection and to the other end of the fuse by a third electrical connection. After the fuse is blown, the safety of the battery cell 21 can be continuously ensured by replacing the fuse. Likewise, the second electric connector and the third electric connector can be any one of an electric socket and an electric plug.
Example two
Referring to fig. 2, a battery control system is provided in the second embodiment of the present invention. The battery control system may include a control module 10 and a battery 20 as described in the first embodiment above. The structure, function, operation principle and effect of the battery 20 can be referred to the description of the first embodiment, and are not repeated herein.
Wherein the first electrical connection 23 of the battery 20 is electrically connected with the control module 10. Specifically, the control module 10 may be provided with a plurality of electrical mating members for corresponding mating with the plurality of first electrical connectors 23. For example, when the first electrical connector 23 is an electrical socket, the corresponding electrical mating element is an electrical plug. When the first electrical connector 23 is an electrical plug, the corresponding electrical mating element is an electrical socket.
In one embodiment, referring to fig. 4, the control module 10 is a battery protection board 11 to monitor the operating state of the battery 20. The battery protection board 11 may include a voltage monitoring unit 111, a temperature monitoring unit 112, or other units. Further, the voltage monitoring unit 111 may be configured to monitor the voltage of each of the battery cells 21 and the total voltage of the plurality of battery cells 21 connected in series as one of the indexes for determining the operating state of the battery 20. The temperature monitoring unit 112 may be configured to monitor the temperature of each of the battery cells 21 and the total temperature of the plurality of battery cells 21 connected in series, as one of the indexes for determining the operating state of the battery 20.

In another embodiment, referring to fig. 5, the control module 10 is a balancing charger 12 to adapt to the voltage balance between different battery cells 21 in the battery 20. In practical applications of the battery cells 21, since the manufacturing, usage conditions and characteristics of each battery cell 21 are different, if this is not improved, the difference is further increased during the charging and discharging processes, and the service life of the battery cell 21 is further reduced. In the embodiment, the balance charger 12 is used as an adapter between the battery cell 21 and an external power source during charging and discharging, so that voltages of different battery cells 21 can be balanced, and the service life of the battery cell 21 can be prolonged.
