Problems solved by technology

[0003] During the operation of the vehicle, if the power battery is in a static state for a long time, such as when the vehicle is in a parked state and has not been powered off for a long time, the SOC value at this time may be re-determined according to the open circuit voltage method, resulting in the power battery being in use. There is a jump in the SOC value during the process
Therefore, there is a technical problem in the related art that the SOC value jumps during the use of the power battery

Embodiment Construction

[0046] 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.

[0047] like figure 1 Shown is a method for correcting the remaining power of a power battery according to an exemplary embodiment of the present disclosure, and the method includes the following steps.

[0048] In step S11, the real value of the remaining power at the previous moment is acquired;

[0049] In step S12, acquire the display value of the remaining power at the last moment;

[0050] In step S13, according to the real value of the remaining power at the previous moment, the displayed value of the remaining power at the previous time, and the convergence value of the preset remaining power, determine the displayed value of the remaining power at t...

Abstract

The invention relates to a power battery remaining power correction method and device, a vehicle and a storage medium. The method comprises the steps that the real value of the remaining power at a previous moment is acquired; the display value of the remaining power at the previous moment is acquired; according to the real value of the remaining power at the previous moment, the display value ofthe remaining power at the previous moment and the convergence value of preset remaining power, the display value of the remaining power at the current moment is determine; the power battery is discharged after a period of time, and the real value of the remaining power after discharging and the display value of the remaining power after discharging are all equal to the convergence value of the preset remaining power. According to the invention, the jump of the display value of the remaining power during the use process of the power battery is effectively solved, and the experience of a driveris improved.

Description

technical field [0001] The present disclosure relates to the technical field of batteries, and in particular, to a method, device, vehicle and storage medium for correcting the remaining power of a power battery. Background technique [0002] The remaining power (state of charge, SOC) of the power battery is a key parameter of the power battery, which can represent the state of use of the power battery. In related technologies, when the vehicle is powered on, the open-circuit voltage look-up method is used to determine the SOC value when the power is turned on. During the charging and discharging process of the power battery, the SOC value is determined by the ampere-hour integration method or other methods. [0003] During the operation of the vehicle, if the power battery is in a static state for a long time, such as when the vehicle is in a parked state and has not been powered off for a long time, the SOC value at this time may be re-determined according to the open circ...
