Abstract

The invention relates to an energy feedback type single battery series charging and discharging detection system and its realization method. The system includes a main circuit and several acquisition control systems. Several single power batteries and switches between the positive and negative electrodes, each single power battery and switches are alternately connected in series, each single power battery is connected in series with the corresponding switch and then connected in parallel with a battery simulator, the battery simulation The input terminal of each acquisition control system is respectively connected with the corresponding battery simulator and single power battery, and the output terminal of each acquisition control system is respectively connected with the corresponding battery simulator and switch. The application realizes the charging and discharging of each single power battery under the condition that the output current of the bidirectional DC / DC power supply remains unchanged, ensuring the consistency of the single power battery during the charging and discharging process, and avoiding the transient current impact on the switch. Shorten charging and discharging time.

Description

technical field [0001] The invention relates to the technical field of battery formation, in particular to an energy feedback type single battery series charge and discharge detection system and an implementation method. Background technique [0002] The traditional method of charging and discharging a single power battery (that is, battery formation) uses a single charging and discharging device to charge and discharge a single battery. The charging and discharging of multiple monomer batteries requires multiple charging and discharging equipment for single power batteries. Using multiple charging and discharging equipment for single power batteries requires more wiring and a large footprint, which increases the cost of battery companies, and the use of different equipment due to Factors such as the discrete type of power devices, the consistency of the Hall, and the temperature environment where the equipment is located cannot guarantee that the current accuracy and curren...
