Abstract

The invention discloses a vehicle battery. The vehicle battery comprises a plurality of universal battery packs which are connected in series or in parallel, each universal battery pack comprises a plurality of battery cells which are arranged in a battery shell and are connected in series or in parallel and a battery management system, and an identity recognition module is arranged in the batterymanagement system. The identity recognition module is used for recognizing a vehicle model which is subjected to echelon utilization by the universal battery pack; Each universal battery pack is provided with a first echelon vehicle model battery interface and a second echelon vehicle model battery interface, the first echelon vehicle model battery interface is used for being connected with a first echelon vehicle model, and the second echelon vehicle model battery interface is used for being connected with a second echelon vehicle model. The battery pack disclosed by the invention can be directly utilized to next suitable vehicle models such as electric bicycles, electric motorcycles and the like in an echelon manner without disassembly and assembly, so that the echelon utilization is more convenient, the echelon utilization cost is reduced, and the echelon utilization process is simplified.

Description

technical field [0001] The invention relates to the technical field of automobile power batteries, in particular to a vehicle battery. Background technique [0002] In recent years, China has given great support to new energy vehicles, and China has become the world's largest new energy vehicle market. Under the prosperous new energy vehicle market, the market demand for power batteries continues to rise. At the same time, limited by the service life of power batteries, the number of power batteries that will be scrapped in the future is extremely large. With the arrival of the first batch of decommissioning peaks of domestic power batteries, the management and storage of decommissioned power batteries have become more and more important. The widely recognized method for decommissioned batteries is direct dismantling and recycling or cascade utilization. [0003] Most of the remaining capacity of retired batteries is 60% to 80% of the initial capacity. If these cells are d...
