Abstract

The invention relates to a method and a device for determining the charge and discharge performance of a battery cell, a storage medium and electronic equipment, a preset target battery cell model can be obtained, wherein the target battery cell model is used for simulating the charge and discharge performance of a target battery cell at a preset environment temperature. The target battery cell comprises a battery cell made of at least two layers of coated electrodes; the process of constant-current rate charging or constant-current rate discharging of the target battery cell at the preset environment temperature is simulated according to a first preset current through the target battery cell model; target performance parameters of a target battery cell are determined according to the simulation result, and the target performance parameters comprise charging performance parameters when the target battery cell is subjected to constant-current rate charging at the preset environment temperature or discharging performance parameters when the target battery cell is subjected to constant-current rate discharging at the preset environment temperature.

Description

technical field [0001] The present disclosure relates to the field of battery performance detection, and in particular, to a method, device, storage medium and electronic equipment for determining the charging and discharging performance of a battery. Background technique [0002] With the urgent demand for new energy vehicles in the market, power battery companies must also speed up the iteration speed of batteries and shorten the R&D cycle. In order to improve the performance of batteries, a positive pole piece with a double-layer coating structure is proposed in related technologies. It improves the compatibility between coatings, avoids the dissolution of the internal coating by double-layer coating, improves the flatness of the surface of the pole piece, effectively improves the safety performance of lithium-ion batteries, and also has a positive effect on the rate performance and cycle performance of the battery. A certain improvement, but how much the performance of t...
