Abstract

The invention relates to a formation detection system and a formation detection method for secondary batteries. The system comprises a direct current (DC) bus, at least one alternating current (AC) / DC device, a plurality of DC-based charging and discharging devices, a plurality of data acquisition devices and a control device, wherein the AC / DC device provides power for the DC bus; one charging and discharging device is connected with a group of secondary batteries and used for controlling the charging and discharging of a single secondary battery according to a charging / discharging control command for the single secondary battery, which is transmitted by the control device, and controlling the simultaneous discharging of all secondary batteries in a secondary battery group according to a discharging control command for the group, which is transmitted by the control device; one data acquisition device is connected with a group of secondary batteries and the control device; and the control device is used for transmitting the charging / discharging control command for the single secondary battery and the discharging control command for the secondary battery group according to detected data transmitted by the data acquisition device.

Description

technical field [0001] The invention relates to a secondary battery production technology, in particular to an energy-saving secondary battery formation detection system and a method based on the system. Background technique [0002] In the production process of secondary batteries (i.e. rechargeable batteries), the formation and detection process is a very important and necessary process. The formation detection process is to charge and discharge the secondary battery several times after the secondary battery is assembled, so as to complete the entire production process of the secondary battery. [0003] At present, the formation detection equipment for secondary batteries, especially for large-capacity power secondary batteries, is mostly based on phase-controlled AC power supply to realize the formation detection of secondary batteries, and the secondary battery is usually used during the discharge process of the secondary battery. The electrical energy in the air is rel...
