In addition to providing SOC information, supplementary information can be provided by calculating the power consumption of the ESS product's air conditioning system and electrical systems.

[0065] In conventional ESS operation, the state of charge (SOC) of the battery is a very important factor and is provided by various SOC operation algorithms based on the cell voltage, temperature and current of the battery, but does not provide usable discharge energy (UDE) information based on actual power consumption.

[0066] In a conventional ESS product, the system 110 used to provide the battery's State of Charge (SOC) may include a battery 111, an air conditioning system 112, electrical facilities 113, and a battery management system (BMS) 114. In a conventional ESS product, the system 110 used to provide the battery's SOC can provide the battery's SOC by (or through the use of) the BMS 114 calculating the battery's SOC based solely on information received from the battery 111, without considering the power consumption information of the air conditioning system 112 and electrical facilities 113. ).

[0067] In contrast, the system 120 for providing UDE information according to embodiments of this disclosure may include components such as a battery 121, an air conditioning system 122, electrical facilities 123, and a BMS 124, but may perform SOC operation and facility load operation by additionally receiving power consumption information of the air conditioning system 122 and electrical facilities 123 along with information from the battery 121 through the BMS 124. In such embodiments, the air conditioning systems 112, 122 may include coolers and heating, ventilation, and air conditioning (HVAC). The electrical facilities 113, 123 may include switch-mode power supplies (SMPS) and power line communication (PLC).

[0068] The BMS can provide power consumption information by calculating the load of all facilities of the ESS product and can consider the usable discharge energy (UDE) from the perspective of ESS operation. In such an embodiment, facility efficiency can refer to the amount of power consumed by the operation of the facility during battery operation.

[0069] Figure 2 This is a block diagram of a system 200 for providing UDE information based on power consumption, according to embodiments of the present disclosure.

When the battery is being charged, it can determine that the battery is in charging mode and can calculate the battery's SOC (State of Charge). And can calculate the SOC ( ) is sent to EMS. In such a case, according to embodiments of this disclosure, SOC ( This differs from UDE. According to embodiments of this disclosure, UDE can be calculated even when the battery is not being charged.

[0072] When the charging mode determination unit 210 determines that the battery is not being charged, the SOC calculation unit 220 can calculate the current SOC of the battery. ).

[0073] The discharge efficiency calculation unit 230 can calculate discharge efficiency information by receiving battery discharge current information. ).

Figure 4 This is a table illustrating examples of the battery discharge efficiency of an ESS system based on the output and the power consumption based on the outdoor temperature and the output, according to embodiments of the present disclosure.

[0075] refer to Figure 4 In Example Table 410 of the ESS system's battery discharge efficiency, the battery discharge efficiency is 97% when the discharge current (e.g., output) is 0.25 CP, 95% when the discharge current is 0.33 CP, and 93% when the discharge current is 0.50 CP. In this case, the battery's SOC information and discharge efficiency can be obtained based on the SOC operating information and discharge current information from each battery rack.

[0076] Return to reference Figure 2 The facility efficiency calculation unit 240 can receive information from the cooler ( Information on heating, ventilation, and air conditioning (HVAC) ) to calculate facility efficiency information ( In such an embodiment, only discharge efficiency information may be received. ), and when calculating facility efficiency information ( When using only cooler information, you can use only the cooler information. ) and HVAC information ( ).

[0078] Cooler information can be calculated based on fan speed and LPM information, and an example table 510 is provided. Figure 5As shown in the diagram. Power consumption may vary depending on the cooler's operating mode. Operating modes can be categorized as idle mode, low operating mode, normal operating mode, and peak operating mode. In idle mode, a power consumption of 4 kW can be obtained based on 0% fan speed and 20 LPM. In low operating mode, a power consumption of 10 kW can be obtained based on 60% fan speed and 90 LPM. In normal operating mode, a power consumption of 14 kW can be obtained based on 80% fan speed and 90 LPM. Finally, in peak operating mode, a power consumption of 18 kW can be obtained based on 100% fan speed and 90 LPM. In these cases, the cooler information refers to the cooler's power consumption.

[0079] Furthermore, HVAC information can be calculated based on fan speed information, and an example table 520 is provided. Figure 5 As shown in the diagram. HVAC power consumption can vary depending on the operating mode. Operating modes can be categorized as idle mode, low operating mode, normal operating mode, and peak operating mode. In idle mode, power consumption of 0.2 kW can be obtained based on 0% fan speed. In low operating mode, power consumption of 0.5 kW can be obtained based on 60% fan speed. In normal operating mode, power consumption of 0.8 kW can be obtained based on 80% fan speed. Finally, in peak operating mode, power consumption of 1.2 kW can be obtained based on 100% fan speed. In such cases, HVAC information can refer to HVAC power consumption information.

[0080] In this case, power consumption can be calculated according to Equation 1.

[0081] Equation 1:

[0082]

[0083] In equation 1, C rate This refers to discharge efficiency. Other facilities include switch-mode power supplies (SMPS) and power line communication (PLC). Once a fixed variable value is obtained, it can be replaced. Fixed variable values ​​do not need to be replaced unconditionally.

[0084] After that, power consumption information ( Divide by the battery design capacity information ( The obtained value is multiplied by 100 and then subtracted from 1 to calculate facility efficiency information. ).

[0085] Facility efficiency information ( It can be calculated according to Equation 2.

[0087]

[0088] Return to reference Figure 2 The UDE computing unit 250 can be based on SOC ( ), discharge efficiency information ( ) and facility efficiency information ( This is used to calculate the usable discharge energy (UDE) information.

[0089] UDE information can be calculated using Equation 3.

[0092] For example, refer to Figure 4 According to the table, if a 0.5CP discharge occurs in an ESS operating environment at an external temperature of 23°C with a battery capacity of 5 MWh per unit container and a battery SOC of 50%, then the UDE can be calculated as 2.5MWh × 93% x 98.62% = 2292.9 kWh (i.e., the actual discharge amount).

[0093] The UDE calculated by the UDE calculation unit 250 can be sent to the EMS.

[0096] When the Energy Management System (EMS) requests the Battery Management System (BMS) to calculate UDE information, the charging mode determination unit 210 can determine whether the battery is in a charging state. When the battery is being charged, it can determine that the battery is in charging mode and can calculate the battery's SOC (State of Charge). And can calculate the SOC ( The SOC (System Origin and Components) is sent to EMS. In this case, according to an embodiment of this disclosure, the SOC (System Origin and Components) is sent to EMS. This differs from UDE. When the battery is not being charged, UDE can be calculated according to an embodiment of this disclosure (S310).
