Specifically, the tray to be screened is a tray for carrying a plurality of formed batteries, and the batteries in the tray to be screened are classified into different categories according to different capacities, open-circuit voltages, direct-current resistances and alternating-current resistances.

The tray to be screened is generally composed of a first type of battery 71 and a non-first type of battery 71; the first type of battery 71 is a class of batteries, and the non-first type of battery 71 means a battery that is not the first type of battery 71, and the non-first type of battery 71 includes one or more batteries that are not the first type of battery 71. In some cases, the tray to be screened may include only the first type of batteries 71, or the tray to be screened may include only the non-first type of batteries 71.

In the existing battery category, the classification from high to low is still carried out in qualified batteries, and the actual capacity of the battery is more than 95% of the theoretical design capacity, between 90% and 95%, between 85% and 90%, and between 80% and 85% by way of example; the failed battery is a battery whose actual capacity is 80% or less of the theoretical design capacity. The batteries having an actual capacity of 95% or more of the theoretical design capacity may be classified as the first type batteries 71, and the batteries having an actual capacity of 95% or less of the theoretical design capacity may be classified as the non-first type batteries 71, and the non-first type batteries 71 include those which are non-defective.

When a plurality of batteries are assembled into a group of batteries, the higher the consistency among the plurality of batteries is, the more stable the performance of the group of batteries is. In the present embodiment, the first type of battery 71 cannot be simply understood as a qualified battery, but should be a battery having high performance uniformity, and the actual capacity of each battery is 95% or more of the theoretical design capacity in the present embodiment.

The battery consistency means that after the single batteries with uniform specification and model form a battery pack, certain differences exist in parameters such as voltage, charge quantity, capacity and decay rate, internal resistance and change rate thereof, service life, temperature influence, self-discharge rate and the like.

In the present embodiment, the non-first type batteries 71 are taken out from the tray to be screened, and not only one type of batteries, or the batteries of the reject product, are taken out.

When the controller recognizes that the trays to be screened filled with batteries are all of the first type of batteries 71, the controller judges that the trays are filled with batteries and fills the trays 61, and the controller controls the filled trays 61 filled with batteries to move to the filling station 3.

In the prior art, batteries in trays mixed with two or more types of batteries are taken out and then put into the tray where the corresponding type is located, so as to sort the batteries of the multiple types.

The greater the ratio of the number of the first-type batteries 71 to the total number of all the batteries, the higher the sorting efficiency.
