Problems solved by technology

However, the decommissioning of existing batteries is generally recycled when the battery fails or is completely unusable or is regularly tested by the manufacturer.
After the battery is recycled, due to the limitation of detection conditions, the state of the recycled battery cannot be accurately detected, and the recycled battery cannot be accurately classified
Therefore, when the battery is reused, it is difficult to achieve effective cascade utilization, resulting in waste of energy

Abstract

The invention discloses a battery management method, a charging cabinet and a battery management system. The cycle number of a battery is recorded after detecting that the charging curve or discharging curve of the battery meets the predetermined requirements, also after detecting that the maximum power attenuation of the battery reaches an attenuation threshold, the battery is controlled and prohibited in used, also whether the cycle number of the battery reaches a quality assurance threshold is judged, and then a quality assurance mark or decommissioning mark is made. The battery managementmethod, the charging cabinet and the battery management system provided by the invention can achieve accurate detection of the states of recycled batteries and gradient utilization of recycled batteries effectively.

Description

technical field [0001] The invention relates to the field of battery management, in particular to a battery management method, a charging cabinet and a battery management system. Background technique [0002] After the battery of an electric vehicle has been used for a period of time, the capacity or power characteristics of the battery will decline significantly, and it will not be able to bring sufficient power to the electric vehicle, so it needs to be retired from the power market. However, the decommissioning of existing batteries is generally done when the battery fails or is completely unusable or is periodically tested by the manufacturer before being recycled. After the battery is recycled, due to the limitation of detection conditions, the state of the recycled battery cannot be accurately detected, and the recycled battery cannot be accurately classified. Therefore, when the battery is reused, it is difficult to realize effective cascade utilization, resulting in...
