Abstract

The invention discloses a multidimensional staged battery performance valuation method based on a charging process. The method comprises the steps of acquiring basic information of a power battery system for a vehicle, recording in a database, evaluating the battery performance, etc. The battery performance evaluation method is advantageous in that through analyzing the inherent characteristic andthe later use condition of the battery, and combining real-time data and historical data, the method is compatible with different data sources and data types; and quick, accurate, multidimensional and staged evaluation to the battery performance is realized.

Description

technical field [0001] The invention relates to a battery performance evaluation method, in particular to a battery performance evaluation method based on a multi-dimensional step-by-step charging process, and belongs to the field of battery performance evaluation methods. Background technique [0002] With the rapid growth of the new energy industry in recent years, the amount of scrapped power batteries will also increase in the future. From 2015 to 2017, the sales of new energy vehicles in my country will continue to increase. According to the operating mileage of about 100,000-200,000 kilometers, the use of 3-5 years It is estimated that 300,000 vehicles will enter the used car market in 2019. According to the 8-year scrapping period, it is estimated that the amount of scrapping in 2019 will reach 322,000 tons. The market is huge, and the recycling and utilization of power batteries is imminent. [0003] For such a large amount of decommissioned batteries, according to t...
