Battery production method and system

A battery production method, applied to a battery production system, wherein the battery production system comprises an upper-level computer, a production device in a first process, a station device in a second process, and a manufacturing execution system, the method comprising:

• determining, by the upper-level computer, a quantity of first battery cells based on a current first production work order in a process of producing products by the production device in the first process of a battery production line, wherein the quantity of the first battery cells is a quantity of battery cells actually required for the current first production work order;
• determining, by the upper-level computer, a quantity of second battery cells, wherein the quantity of the second battery cells is a quantity of battery cells determined to be qualified for the current first production work order;
• in response to the quantity of the second battery cells being greater than or equal to the quantity of the first battery cells, sending, by the upper-level computer, a control instruction to a first production device in the first process, and taking a next first production work order as the current first production work order so as to complete switching of the first production work order, wherein the control instruction is used for the first production device to stop working;
• determining, by the manufacturing execution system, a quantity of unfinished battery packs on the station device for a current second production work order and sending the quantity of the unfinished battery packs to the station device in a process of producing products by the station device in the second process of the battery production line;
• and
• in response to the quantity of the unfinished battery packs being zero, taking, by the station device, a next second production work order as the current second production work order so as to complete switching of the second production work order.
