[0097] refer to Figure 5 , the second embodiment of the present invention provides a capacity calibration method for an energy storage system, based on the above Figure 4 In the first embodiment shown, the step S10 includes:

[0098] Step S11, when it is detected that the time condition for triggering the calibration is met, it is detected whether the calibration condition is met, and the calibration condition is that the remaining power of the power generation system is higher than the set power, or the target charging time period is in a low power consumption period;

[0099] The calibration conditions are the conditions that need to be met for further calibration, or the conditions that need to be met for further sending a discharge request to the inverter system. The purpose of setting the calibration conditions in this embodiment is to reduce the cost of calibration. Discharging the battery to a fully discharged state and charging it to a fully charged state may consum...

Abstract

The invention discloses a capacity calibration method of an energy storage system, a battery management system and an inverter system. The energy storage system comprises the battery management system and the inverter system, and the capacity calibration method of the energy storage system is applied to the battery management system. The capacity calibration method of the energy storage system comprises the following steps: when a time condition of triggering calibration is detected to be satisfied, sending a discharge request to an inverter system, so as to make the inverter system discharge a battery to a complete discharge state according to the discharge request; when it is detected that the battery is in the complete discharging state, sending a charging request to the inverter system, so as to make the inverter system charge the battery to a complete charging state according to the charging request; and determining the total electric quantity consumed by charging to the complete charging state, and taking the total electric quantity as the calibrated battery capacity of the energy storage system. According to the invention, the battery capacity of the energy storage system can be calibrated in time.

Description

technical field [0001] The invention relates to the technical field of battery management, in particular to a capacity calibration method of an energy storage system, a battery management system and an inverter system. Background technique [0002] Energy storage systems, such as household energy storage systems, need to calculate the current state of charge (State of Charge, SOC) to be applied in various power consumption scenarios. The battery capacity of the energy system can be calculated. Among them, as the environmental conditions change, the number of charge and discharge increases, and the physical characteristics of the battery itself are limited, the battery capacity will gradually decrease. Therefore, in order to obtain a more accurate value of the battery capacity, it is necessary to The total capacity of the battery is calibrated. When the exemplary technology is calibrated, it will continuously detect whether the energy storage system is just in a certain condi...
