In order to solve the above technical problems, the present inventors have improved this and have proposed the following technical solutions.
The vehicle-mounted battery 100 according to the embodiment of the invention is described below with reference to fig. 1 to 5.

Specifically, the space of the vehicle is limited, and besides the requirement for a comfortable seat space and necessary components, the installation space and position of the vehicle-mounted battery 100 are limited, and the limited installation space also needs to be fully utilized to increase the capacity of the vehicle-mounted battery, which further limits the thickness and number of the single batteries, and further limits the leading-out directions of the positive electrode and the negative electrode in the vehicle-mounted battery under the condition that the number of the single batteries in the vehicle-mounted battery is limited (for example, when one vehicle-mounted battery can only install odd number of first single batteries connected in series, the first leading-out end and the second leading-out end of the vehicle-mounted battery can only be led out from different side wall surfaces of the vehicle-mounted battery); the vehicle-mounted battery is provided with a first side wall surface 101 and a second side wall surface 102 which are opposite to each other, so that the vehicle-mounted battery is conveniently electrically connected with other circuit elements and the safety and the service life of the vehicle-mounted battery are ensured, when a first leading-out end and a second leading-out end of the vehicle-mounted battery containing odd-numbered single batteries are required to be led out in the same direction, even-numbered first single batteries and even-numbered second single batteries can be matched and connected, and meanwhile, the first leading-out end and the second leading-out end are arranged on the first side wall surface 101 or are arranged on the second side wall surface 102, so that the first leading-out end and the second leading-out end of the vehicle-mounted battery containing odd-numbered single batteries can be led out in the same direction, and the vehicle-mounted battery 100 can meet different connection requirements.

In addition, as shown in fig. 5, the second unit cell 10 includes a third electrode 11, a fourth electrode 13, and a fifth electrode 12, wherein two of the third electrode 11, the fourth electrode 13, and the fifth electrode 12 are of the same polarity, the other electrode is opposite to the polarity thereof, the two electrodes of the same polarity are disposed on different sidewall surfaces, and the other electrode having an opposite polarity thereto may be disposed on the same sidewall surface or on a different sidewall surface from one of the electrodes. For example, the third electrode 11 and the fourth electrode 13 are positive electrodes, the fifth electrode 12 is a negative electrode, the third electrode 11 and the fourth electrode 13 are respectively disposed at the third end 16 and the fourth end 17 of the second unit cell 10, the fifth electrode 12 may be disposed at the third end 16 or the fourth end 17 of the second unit cell 10, and the fifth electrode 12 may also be disposed at other sidewall surfaces of the second unit cell. Of course, the third electrode 11 and the fifth electrode 12 may be positive electrodes, and the fourth electrode 13 may be a negative electrode; the fourth electrode 13 and the fifth electrode 12 may be positive electrodes, and the third electrode 11 may be a negative electrode; the third electrode 11 and the fourth electrode 13 may be negative electrodes, and the fifth electrode 12 may be a positive electrode; the third electrode 11 and the fifth electrode 12 are negative electrodes, the fourth electrode 13 is a positive electrode, the fourth electrode 13 and the fifth electrode 12 are negative electrodes, and the third electrode 11 is a positive electrode.
Further, one of the first to second electrodes 21 to 22 is configured as a first lead, and one of the third, fourth, and fifth electrodes 11, 13, and 12 is configured as a second lead. That is, the first electrode 21 is a first lead-out terminal, or the second electrode 22 is a first lead-out terminal; the third electrode 11 is a second lead-out terminal, or the fourth electrode 13 is a second lead-out terminal, or the fifth electrode 12 is a second lead-out terminal.
The first terminal and the second terminal are disposed on the same side wall surface of the vehicle-mounted battery 100, and the polarities of the first terminal and the second terminal are opposite.
In a specific example, as shown in fig. 1 in conjunction with fig. 2, 3, and 4, an even number of first unit cells 20 are stacked, and the second unit cells are connected to and stacked on adjacent ones of the first unit cells, and any adjacent two of the first unit cells are connected in series. An even number of first unit cells 20 and one second unit cell 10 are stacked, and two adjacent first unit cells 20 are reversely mounted, for example, the first electrode 21 of the first unit cell 20 is a positive electrode, the second electrode 22 is a negative electrode, one of the first electrodes 21 of the first unit cell 20 is a first lead-out terminal, the fourth electrode 13 and the fifth electrode 12 of the second unit cell 10 are disposed on the same side of the second unit cell 10 and have opposite polarities, wherein the fourth electrode 13 is a positive electrode, the fifth electrode 12 is a negative electrode, and the fifth electrode is configured as a second lead-out terminal, further, the first electrode 21, the fifth electrode 12, and the fourth electrode 13 are all disposed on the same side wall surface of the vehicle-mounted battery 100, and thus, the first lead-out terminal and the second lead-out terminal of the vehicle-mounted battery composed of odd number of unit cells can be led out on the same side of the vehicle-mounted battery.
It is easily understood that the number of the even number of the first unit cells 20 plus the number of the second unit cells 10 is an odd number, and as mentioned in the background of the present application, in the actual production application, the vehicle-mounted battery 100 is used for being mounted on the vehicle, the space for mounting the vehicle-mounted battery 100 is limited, that is, the volume of the vehicle-mounted battery 100 is limited, and the volume of the unit cells is determined, and in the limited volume, only the odd number of the unit cells may be accommodated. In order to facilitate the connection of the wires, the positive electrode and the negative electrode of the vehicle-mounted battery 100 are often required to be arranged on the same side of the vehicle-mounted battery 100, and when the number of the single batteries is odd, the total positive electrode and the total negative electrode of the single batteries are arranged on the two opposite sides of the vehicle-mounted battery 100, which is inconvenient to install.
In order to meet the consistency of the single batteries and meet the requirement that a customer needs to be led out from the same side of the battery, as shown in fig. 6, an electric connection copper bar is conventionally led out from the other side of the vehicle-mounted battery in the field, and the overlong electric connection copper bar increases the parts of the vehicle-mounted battery 100 and increases the design and use cost; the space in the battery system is limited, and the design and arrangement difficulty is increased; the number of conductive structural parts in the battery is increased, so that electric leakage and safety risks are increased; the heavy current passes through the electricity and connects the copper bar, and this electricity connection copper bar sets up again with the battery surface, can increase the inside temperature of battery, influences the life of battery.

Therefore, according to the vehicle-mounted battery 100 provided by the embodiment of the invention, the first leading-out terminal and the second leading-out terminal of the vehicle-mounted battery composed of odd number of single batteries can be led out at the same side of the vehicle-mounted battery. The installation is convenient, the copper bar which is too long is avoided, the number of parts is reduced, and the safety performance is higher.
In the related art, the vehicle-mounted battery generally consists of a plurality of first single batteries, so that the electrodes cannot be led out from two sides, and great inconvenience is brought to the installation of a circuit. It can be understood that under the certain condition of installation space, for example, odd number battery cell can only be installed to this installation space, this application only need with in a plurality of original battery cell one replacement for the second battery cell can, like this, the equipment of battery module and shaping process are little with the difference, have guaranteed with original battery module's uniformity, are favorable to reduce cost.

In some embodiments, the vehicle-mounted battery 100 further includes a conductive connecting member 30, and any two adjacent first single batteries 20 are electrically connected through the conductive connecting member 30; the first unit cell 20 and the second unit cell 10 adjacent to the second unit cell 10 are electrically connected by the conductive connection member 30. The first single battery 20 and the second single battery 10 are single batteries, that is, any two adjacent single batteries are electrically connected through the conductive connecting member 30, and the conductive connecting member 30 is electrically connected with the positive electrode of one single battery and the negative electrode of the other single battery. This makes it possible to connect a plurality of unit batteries in series and increase the output voltage of the in-vehicle battery 100. Preferably, the conductive connection member 30 connects two adjacent unit cells, thereby making the length of the conductive connection member 30 short, facilitating the connection, and also making the structure of the unit cell 100 clear.
In some embodiments, the first electrode 21 in the first unit cell 20 is a positive electrode, one of an even number of the first electrodes 21 is configured as a first lead, the fifth electrode 12 is a negative electrode of the second unit cell 10, and the fifth electrode 12 is configured as a second lead.
