Abstract

Embodiments of the present invention provide a method, device, device, and storage medium for determining battery power. The method includes: determining the real-time voltage of the target battery; if the target battery is in a discharge state, based on the mapping relationship between the real-time voltage and the target voltage and power, Determine the remaining power of the target battery, and the target voltage and power mapping relationship is the mapping relationship between the voltage of the target battery and the remaining power; if the target battery is in a charging state, then determine the target battery based on the mapping relationship between the real-time voltage and the actual voltage of the target charging voltage The actual voltage of the target battery, and based on the mapping relationship between the actual voltage of the target battery and the target voltage, the remaining power of the target battery is determined. The actual voltage mapping relationship of the target charging voltage is the mapping relationship between the charging voltage and the actual voltage of the target battery. According to the technical solutions of the embodiments of the present invention, it is possible to avoid the problem of inaccurate power calculation due to differences in voltage and power curves during charging and discharging.

Description

technical field [0001] The present invention relates to the technical field of batteries, in particular to a method, device, equipment and storage medium for determining battery power. Background technique [0002] Lithium batteries have many advantages such as high energy, long service life, high rated voltage, low self-discharge rate, and light weight, and have been widely used in various electronic devices. The power calculation of lithium batteries is the basis of battery power management, how to determine the power of lithium batteries has become the focus of attention. [0003] In one technical solution, the remaining power of the battery is obtained through the voltage and power curve of the open circuit voltage of the battery corresponding to the state of charge (State Of Charge, SOC). However, in this technical solution, the voltage and electricity curves vary greatly during charging and discharging, such as figure 1 As shown, under the same battery voltage, the S...
