Embodiment Construction

[0077] In a preferred embodiment, a method for environmentally friendly utilization of waste power batteries of new energy vehicles comprises the following steps:

[0078] S1. Screen out waste power batteries, wherein the SOH of the screened out waste power batteries is not less than 50%.

[0079] S2. Detect the waste power batteries in step S1, recombine and integrate the waste power batteries that meet the detection standards, and obtain a battery pack.

[0080] In this embodiment, the method includes step S3, which uses a cascaded power conversion system to charge and discharge the battery pack obtained in step S2, see figure 1 , the cascaded power conversion system includes a first filter, one end of which is connected to an alternating current.

[0081] One end of the AC / DC converter is connected to the other end of the first filter.

[0082] The wiring includes a first wiring and a second wiring, one end of the wiring is connected to an AC / DC converter, and a capacitor...

Abstract

The invention discloses an environment-friendly utilization method of a waste power battery of a new energy automobile. The method comprises the following steps of S1, screening waste power batteries,wherein the SOH of each screened waste power battery is not less than 50%; and S2, detecting the waste power batteries in Step S1, and recombining and integrating the waste power batteries meeting adetection standard to obtain a battery pack. The method is good in recycling effect.

Description

technical field [0001] The invention relates to the field of power battery recycling and reuse, in particular to a method for environmentally friendly utilization of waste power batteries of new energy vehicles. Background technique [0002] When the power battery capacity of electric vehicles decays to 80%, it will not be able to meet the applicable standards for electric vehicles. It is expected that power batteries will enter a large-scale recycling stage in the next few years. Although decommissioned power batteries cannot meet their performance requirements in the field of electric vehicles, they can still play a role in the field of energy storage. At the same time, the high cost of energy storage batteries also restricts the promotion and application of battery energy storage industry in my country. Therefore, it is of great significance to use low-cost decommissioned waste power batteries in energy storage systems for environmental protection. [0003] According to ...
