Abstract

The invention provides a battery energy state prediction method and device, electronic equipment and a storage medium. According to the method, working parameter information of a to-be-predicted battery at the current moment is collected, and battery parameter information of the to-be-predicted battery is determined from a preset parameter table. According to the method, the maximum running current which can be reached by the to-be-predicted battery during working is determined according to the battery parameter information, the constraint voltage value and the constraint current value, then the temperature is predicted, the SOP value of the to-be-predicted battery is predicted according to the determined maximum running current and the predicted temperature, and therefore the SOP value of the to-be-predicted battery is determined. According to the embodiment of the invention, the SOP value is predicted from the angles of voltage constraint, current constraint and temperature constraint, it is ensured that the to-be-predicted battery can be safely used in the full SOC period, the peak power output of the SOP value of the to-be-predicted battery is improved, and the endurance and the service life of the to-be-predicted battery are improved.

Description

technical field [0001] The present application relates to the technical field of new energy, and in particular, to a battery energy state prediction method, device, electronic device and storage medium. Background technique [0002] The State of Power (SOP) of the battery is expressed as the maximum power that the battery can release or absorb. At present, the hybrid pulse power characteristic method (HPPC) is commonly used to determine the SOP value of the battery. This method is based on the upper and lower cut-off voltages of the battery, combined with the open circuit voltage. , the internal resistance of the battery is calculated by SOP. [0003] However, the peak power of the battery SOP value determined by the prior art has a short duration and a large jump, and there may also be a risk of the battery being burned due to excessive temperature during the use of the battery. SUMMARY OF THE INVENTION [0004] In order to solve the problems in the prior art, the embodi...
