Problems solved by technology

The operation of single-phase inverter has the maximum efficiency point. When the power is low, the operating efficiency is low. The efficiency of the whole system is low, so it is urgent to design a charging and discharging method with high efficiency of the whole machine when the battery energy storage system is in the two working conditions of low charge state discharge or high charge state charge

Abstract

Embodiments of the present invention relate to the technical field of energy storage, and in particular, relate to a battery charging and discharging method, device, and electronic equipment. The method includes: when performing charge processing on the battery, acquiring a maximum charge parameter of the battery, and a maximum efficiency point power value of the single-phase inverter; according to the maximum charge parameter, and, the The maximum efficiency point power value of the single-phase inverter determines the required number of single-phase inverters; controls the required number of single-phase inverters to work, and controls other single-phase inverters to stop working. Through the above method, the single-phase inverter that needs to work can be determined according to actual needs, so as to improve the overall efficiency of the battery energy storage system under the condition of satisfying the charging and discharging of the battery.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of energy storage, and in particular, relate to a battery charging and discharging method, device, and electronic equipment. Background technique [0002] With the wide application of battery energy storage systems, when charging and discharging the battery, it is necessary to always pay attention to the SOC (State Of Charge) of the battery and the maximum charging and discharging power SOP (State Of Power) of the battery, and use the battery reasonably. The maximum charge and discharge power SOP can maximize the battery utilization and prolong the battery life. [0003] However, in the process of realizing the embodiment of the present invention, the inventors found that: when the SOC of the battery is very low, the maximum discharge power of the battery decreases; when the SOC of the battery is very high, the maximum charging power of the battery decline. The operation of single-pha...
