For each cell in a plurality of cells from a same manufacturing run, a first and a second cell characteristic are received in order to obtain a plurality of cell characteristics. For each cell, a batch compatibility number that is associated with a number of compatible cells that that cell is compatible with is determined based at least in part on the plurality of cell characteristics. The plurality of cells is sorted according to the batch compatibility numbers to obtain a sorted list of cells. A plurality of compatible cells to include in a battery is selected from the plurality of cells, including by evaluating the plurality of cells according to the order of the sorted list of cells and beginning with the lowest batch compatibility number.

A battery recycling method used to recycle used batteries from one or more cell sites includes uniquely identifying and marking the used batteries at the one or more cell sites; packaging and removing the used batteries from the one or more cell sites to a staging facility; packaging the used batteries from a plurality of cell sites at the staging facility with a insulation material; providing the packaged used batteries from the plurality of cell sites to a recycling facility; tracking the used batteries at each foregoing step; and providing a recycling certificate to an operator of the one or more cell sites evidencing successful recycling of the used batteries.

The present disclosure provides a charge control circuit, a charging device and a charging system. The charge control circuit comprises a power input end, a power output end, a switch unit, a control unit and a detection unit, wherein rechargeable batteries comprise a first rechargeable battery and a second rechargeable battery; the power output end comprises a first power output end and a second power output end; the switch unit comprises a first switch and a second switch; a voltage adjustment circuit is connected between the first switch and the first power output end; and when the detection unit detects that the rated voltages of the rechargeable batteries are not the same, the control unit controls the second switch to be closed and the second rechargeable battery is charged, and at the same time the control unit controls the first switch to be closed and activates the voltage adjustment circuit.

The power storage cell includes a cell case, a first two-dimensional identification code, and a second two-dimensional identification code. The cell case is configured to be capable of accommodating an electrode body. The first two-dimensional identification code is provided on an outer surface of the cell case. The first two-dimensional identification code is configured to be able to read the identification information. The second two-dimensional identification code is provided on the outer surface of the cell case spaced apart from the first two-dimensional identification code. The second two-dimensional identification code is configured to be able to read the same identification information as the first two-dimensional identification code. The second two-dimensional identification code is provided at a position where at least a part of the first two-dimensional identification code cannot be visually recognized when the second two-dimensional identification code is viewed from the front.

A battery assembly has a command module with a power connection interface and a battery matrix interface. A battery matrix has a plurality of battery cells, an electrically erasable programmable read only memory (EEPROM) and a command module interface. The battery matrix interface may be removably interconnected with the command module interface, enabling power delivery from the battery matrix through the command module to the power connection interface and review of the EEPROM for capacity feedback with respect to remaining electrical power of the battery matrix.
