According to the utility model provides a battery module, it includes that M arranges the battery row 21 of arranging along the first direction, and every battery row 21 includes a plurality of battery cells 211 of arranging along the second direction, compares with current adoption battery cell of single row and carries out unitized battery module, and the reducible quantity that is used for the structure of fixed battery cell 211 of this kind of unitized mode to be favorable to alleviateing battery module's weight and improving battery module's energy density, therefore it is efficient in groups. In addition, positive electrode interface 30 and negative electrode interface 40 are located the first end of battery module, and output interface 60 is located the second end that sets up with first end is relative, can make voltage connection pencil and sampling pencil separately set up like this to can guarantee the security and the stability that battery module electricity is connected, this kind of wiring mode is pleasing to the eye relatively moreover, the later maintenance of being convenient for.

Specifically, the first direction is disposed at an acute angle or a right angle to the second direction. In this embodiment, the first direction is perpendicular to the second direction. The first direction is the X direction in the figure, and the second direction is the Y direction in the figure.

Further, M is an even number. In this way, the electrical connection between the battery rows 21 can be facilitated.

Further, as shown in fig. 1 to 3, the unit cell 211 near the first end in each battery row 21 is a first unit cell 212, and the unit cell 211 near the second end in each battery row 21 is a second unit cell 213. The M rows of battery rows 21 include first to M rows sequentially arranged at intervals in a first direction, the battery module has a first side and a second side opposite to each other in the first direction, the first row of battery rows 21 is adjacent to the first side, the M row of battery rows 21 is adjacent to the second side, each of the first unit batteries 212 and the second unit batteries 213 includes a first electrode and a second electrode arranged at intervals in the first direction, the first electrode is adjacent to the first side and is a positive electrode, the second electrode is away from the first side and is a negative electrode, the negative electrode of the second unit battery 213 in the odd rows of battery rows 21 is electrically connected with the positive electrode of the second unit battery 213 in the adjacent row of battery rows 21, and the negative electrode of the first unit battery 212 in the even rows of battery rows 21 is electrically connected with the positive electrode of the first unit battery 212 in the adjacent row of battery rows 21.

It can be understood that, with this structure, the path of the electrical connection between two adjacent battery rows 21 is the shortest, which not only makes the length of the connecting member connecting the two battery rows 21 shorter, but also, compared with the connection between two battery rows 21 at other positions, the connection method does not need to be designed to be avoided with other structures, thereby reducing the difficulty of connection between two battery rows 21 and being beneficial to reducing the production cost.

The following is a detailed explanation by taking an example of grouping M =2 and N =10 (2 rows of battery rows 21, each row of battery rows 21 including 10 unit batteries 211).

As shown in fig. 1 to 4, the 10 unit cells 211 in each battery row 21 are connected in parallel two by two and then connected in series. The two cells 211 are connected in parallel and then connected in series in sequence, which means that the two cells 211 are connected in parallel to form a module, and then the modules are connected in series in sequence.

The first row of battery rows 21 and the second row of battery rows 21 are spaced apart in the first direction with the first row of battery rows 21 adjacent the first side and the second row of battery rows 21 adjacent the second side. The first unit cell 212 and the second unit cell 213 in each row of the battery row 21 each include a first electrode and a second electrode arranged at an interval in the first direction. The first electrode is adjacent to the first side and is a positive electrode, and the second electrode is far away from the first side and is a negative electrode. The positive electrode of the first battery cell 212 in the first row of battery rows 21 is electrically connected to the positive electrode terminal 30, and the negative electrode of the first battery cell 212 in the second row of battery rows 21 is electrically connected to the negative electrode terminal 40. The negative electrode of the second unit cell 213 in the cell row 21 of the first row is electrically connected to the positive electrode of the second unit cell 213 in the adjacent and second-side cell row 21 (i.e., the cell row 21 of the second row). So set up, the route that is located the electricity between the battery row 21 of first row and the battery row 21 that is located the second row is the shortest, not only can make the length of connecting two battery rows 21 shorter like this, compare in other positions with two battery rows 21 moreover, this kind of connected mode need not to carry out the design of dodging with other structures to can reduce the degree of difficulty of connecting between two battery rows 21, be favorable to reducing manufacturing cost.

Of course, the other unit cells 211 in each row of the battery row 21 between the first unit cell 212 and the second unit cell 213 may be connected in series and/or in parallel according to actual needs, as long as it can ensure that the positive electrodes of the first unit cell 212 and the second unit cell 213 are both adjacent to the first side, and the negative electrodes of the first unit cell 212 and the second unit cell 213 are both away from the first side.

The following is a detailed description of grouping by taking an example of M =4 and N =10 (4 rows of battery rows 21, each row of battery rows 21 including 10 single batteries 211).

The first unit cell 212 and the second unit cell 213 in each row of the battery row 21 each include a first electrode and a second electrode arranged at an interval in the first direction. The first electrode is adjacent to the first side and is a positive electrode, and the second electrode is far away from the first side and is a negative electrode. The positive electrode of the first battery cell 212 in the first row of battery rows 21 is electrically connected to the positive electrode terminal 30, and the negative electrode of the first battery cell 212 in the fourth row of battery rows 21 is electrically connected to the negative electrode terminal 40. The negative electrode of the second unit cell 213 in the cell row 21 of the first row is electrically connected to the positive electrode of the second unit cell 213 in the adjacent and second-side cell row 21 (i.e., the cell row 21 of the second row). The negative electrode of the first unit cell 212 in the battery row 21 of the second row is electrically connected to the positive electrode of the first unit cell 212 in the battery row 21 adjacent and near the second side (i.e., the battery row 21 of the third row). The negative electrode of the second unit cell 213 located in the cell row 21 of the third row is electrically connected to the positive electrode of the second unit cell 213 in the cell row 21 adjacent and near the second side (i.e., the cell row 21 located in the fourth row).

With the arrangement, the paths of the electrical connection between the battery row 21 positioned in the first row and the battery row 21 positioned in the second row, between the battery row 21 positioned in the second row and the battery row 21 positioned in the third row, and between the battery row 21 positioned in the third row and the battery row 21 positioned in the fourth row are all shortest, so that the length of the connecting piece for connecting the two battery rows 21 is shorter, and compared with the connection of the two battery rows 21 at other positions, the connection mode does not need to be designed to avoid other structures, thereby reducing the difficulty of connection between the two battery rows 21 and being beneficial to reducing the production cost.
