AI Technical Summary
Technical Problem
In existing technologies, battery state of charge (SOC) estimation is easily affected by sensor sampling accuracy, temperature drift, and cell inconsistency, resulting in fluctuating SOC display and affecting user judgment and system reliability.
Method used
By acquiring the battery's true SOC, current, and intermediate state SOC, a dynamic SOC mapping range is determined, and a SOC to be displayed is generated based on the current and SOC mapping range, achieving a smooth transition and continuous display of SOC.
Benefits of technology
It suppresses SOC mutations caused by temperature drift and cell inconsistency, improving the continuity of SOC display and user-perceived credibility.

Abstract
Embodiments of the present application provide a battery SOC display method and device, a new energy vehicle and a storage medium, and relate to the technical field of new energy vehicle battery management. The method obtains the real SOC, the battery current and the intermediate state SOC of the battery of the new energy vehicle in the current display period and the previous display period; determines the SOC mapping interval according to the real SOC, the battery current in the current display period and the intermediate state SOC in the previous display period; obtains the intermediate state SOC in the current display period according to the real SOC in the current display period and the SOC mapping interval; generates the to-be-displayed SOC in the current display period according to the intermediate state SOC in the current display period, and displays the to-be-displayed SOC on the vehicle-mounted screen of the new energy vehicle, thereby suppressing the apparent SOC jump caused by the real SOC mutation caused by temperature drift, current sampling noise or inconsistency of the battery cells, and improving the continuity, stability and user perception credibility of the SOC display.
