Embodiment Construction

[0043] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0044] In order to protect the power battery, under the premise of satisfying the customer's use, it should try to avoid full charging and full discharge of the power battery. For this reason, in actual use, some power batteries will be hidden. For example, assuming that the power battery can be fully charged at 100 amp hours, then when the power battery is charged to 90 amps, the actual power of the power battery is 90% of its full charge capacity, but the meter will give the user The display is 100%, that is, 10% of the fully charged power is hidden to avoid full charging of the power battery. For another example, when the power battery is discharged until ...

Abstract

The invention relates to an instrument SOC mapping method and device, a storage medium, electronic equipment and an electric vehicle, and belongs to the field of electric vehicles, thereby effectivelyeliminating jump of instrument SOC display. The instrument SOC mapping method comprises the steps: acquiring an instrument initial SOC, a BMS initial calculation SOC and a BMS real-time calculation SOC; under the condition that the power battery is charged, mapping the instrument SOC to the direction of an upper SOC mapping boundary by utilizing the instrument initial SOC, the BMS initial calculation SOC and the BMS real-time calculation SOC; and under the condition that the power battery is discharged, mapping the instrument SOC to the direction of a lower SOC mapping boundary by utilizing the instrument initial SOC, the BMS initial calculation SOC and the BMS real-time calculation SOC.

Description

technical field [0001] The present disclosure relates to the field of electric vehicles, and in particular, relates to an instrument SOC mapping method, device, storage medium, electronic equipment, and electric vehicles. Background technique [0002] At present, the state of charge (State of Charge, SOC) of the battery displayed to the user by the instrument of the electric vehicle may jump, which will make the user uncertain about the SOC of the power battery of the electric vehicle, which will bring great harm to the user. Big trouble. Contents of the invention [0003] The purpose of the present disclosure is to provide an instrument SOC mapping method, device, storage medium, electronic equipment and electric vehicle, which can effectively eliminate the jumps displayed by the instrument SOC. [0004] According to the first embodiment of the present disclosure, a meter SOC mapping method is provided, the method includes: acquiring the meter initial SOC, the BMS initia...
