a second transfer structure to transfer batteries at the unloading position to a first starting position of the second transmission line so as to transmit, when the number of batteries at the first starting position reaches N, the N batteries to a first termination position of the second transmission line, wherein N>1.

2. The battery transmission system according to claim 1 , wherein the battery transmission system further comprises: a first identifier to identify types of M batteries received by the material incoming structure, wherein M>1; and
the first transfer structure transfers the M batteries to M first pallets on the first transmission line according to the types of the M batteries.

3. The battery transmission system according to claim 2 , wherein
in the case where the M batteries are all of the same type or all of different types, the first transfer structure transfers the M batteries to the M first pallets on the first transmission line; and
in the case where the M batteries comprise batteries of different types and there are batteries of the same types, the first transfer structure separately transfers the batteries of the same types sequentially to the M first pallets on the first transmission line, wherein batteries transferred by the first transfer structure each time are of the same type and two adjacent transfers are separated by a preset time interval.

4. The battery transmission system according to claim 3 , wherein the first transfer structure transfers, according to the numbers of the batteries of the same types among the M batteries, the batteries of the same types sequentially to the M first pallets on the first transmission line.

5. The battery transmission system according to claim 4 , wherein the first transfer structure transfers, according to the order of the numbers of the batteries of the same types among the M batteries from large to small, the batteries of the same types sequentially to the M first pallets on the first transmission line.

6. The battery transmission system according to claim 1 , wherein the first transmission line has a plurality of unloading positions for which a plurality of second transmission lines are provided correspondingly, each of the second transmission lines corresponding to a battery type; and the battery transmission system further comprises: a second identifier, wherein
the second identifier identifies the type of a battery transmitted to the unloading position; and
the second transfer structure transfers the battery transmitted to the unloading position to a first starting position of a second transmission line corresponding to the type of the battery.

7. The battery transmission system according to claim 6 , wherein the second transfer structure transfers, according to the number a of batteries of a target type that are transmitted to the unloading position and the number b of batteries of the target type that are already present at the first starting position, c batteries transmitted to the unloading position to a first starting position of a second transmission line corresponding to the target type, wherein a≥c, and when a≥N−b, b+c=N.

8. The battery transmission system according to claim 6 , wherein each of the first pallets is independently controlled by a controller, and
the controller is configured to control a first pallet in which the batteries transmitted to the unloading position are located to stop movement when the second transfer structure transfers the batteries transmitted to the unloading position, and control the first pallet to start movement after determining that the batteries in the first pallet are transferred.

9. The battery transmission system according to claim 8 , wherein the first transmission line has a loading position, and the controller is further configured to control the first pallet to stop movement when the first pallet is moved on the first transmission line to the loading position, and control the first pallet to start movement after the first transfer structure transfers batteries to the first pallet.

10. The battery transmission system according to claim 1 , wherein the number of the first pallets on the first transmission line is multiple, each of the first pallets conveys one battery, and adjacent ones of the first pallets are spaced at a preset safe distance during movement on the first transmission line.

11. The battery transmission system according to claim 1 , wherein the second transmission line comprises m connected belts, each belt moving independently under the drive by a motor, the first starting position being the position of the 1st belt and the first termination position being the position of the mth belt, m>1, wherein
when N batteries are transmitted to the mth belt, a motor for the mth belt controls the mth belt to stop movement;
when N batteries are transmitted to the mth belt and there are N batteries present on each of k1 consecutive belts located after the mth belt, motors for the k1 consecutive belts after the mth belt control the k1 consecutive belts to stop movement, respectively, k1≥1;
when N batteries are transmitted to the ith belt and there are no batteries on the (i+1)th belt, a motor for the ith belt controls the ith belt to move, i≥1; and
when N batteries are transmitted to the ith belt and there are N batteries present on each of k2 consecutive belts located before the ith belt and none of the k2 consecutive belts is the mth belt, the motor for the ith belt controls the ith belt to move and motors for the k2 consecutive belts control the k2 consecutive belts to move, respectively, k2≥1.

12. The battery transmission system according to claim 1 , wherein the battery transmission system further comprises:
an assembly structure to assemble based on batteries that are at the first termination position to obtain a battery pack.

13. The battery transmission system according to claim 12 , wherein the battery transmission system further comprises: a third transmission line corresponding to the second transmission line, and
the assembly structure transfers the batteries at the first termination position to a middle cover of the third transmission line and, after a layer of batteries is arranged all over the middle cover, transfers a new middle cover onto the layer of batteries; and
if the number of battery layers does not reach a preset number of layers, the assembly structure continues to transfer batteries to the new middle cover until the number of battery layers reaches the preset number of layers to obtain an assembled battery pack.
