[0041] The energy storage unit is used to store electric energy. In a specific embodiment, the electric energy stored in the energy storage unit is 24V direct current. However, it should be noted that the present application does not limit the specific electric energy specifications.
[0042] The electric energy allocation unit is used to allocate electric energy according to the power storage situation of the energy storage unit to meet the power demand of each power consuming unit, thereby realizing unified allocation of energy in the convenience service station, and can intelligently allocate electric energy according to the power demand of each power consuming unit, including different energy consumption, different power consumption time, different power consumption, etc., give priority to meeting the power demand of low-energy consumption power consuming units, give priority to meeting the power demand of convenience service type power consuming units, thereby not only meeting the power demand of each power consuming unit, but also effectively improving the energy utilization rate of the convenience service station.
[0043] In one embodiment, the control module is used to calculate the charge state of the energy storage unit, and accordingly control the power conversion unit to convert the electric energy provided by the energy input module into electric energy of specified specifications, and store it in the energy storage unit to charge the energy storage unit; according to the power demand of each power consuming unit, control the power allocation unit to allocate electric energy from the energy storage unit, and provide it to each power consuming unit after converting it into the electric energy of the specifications required by each power consuming unit through the power conversion unit to power each power consuming unit; calculate the health status of the energy storage unit, and accordingly send early warning information to an external operation center through the network communication module.
[0044] In a specific embodiment, if Figure 2 As shown, the control module charges the energy storage unit according to the charge state of the energy storage unit, including steps S101 to S103.
[0045] Step S101: Calculate the state of charge of the energy storage unit in real time, and when the state of charge of the energy storage unit is less than a preset first charge threshold, determine whether the non-mains power unit in the energy input module has power transmission capability.
[0046] In one embodiment, the state of charge of the energy storage unit is calculated as shown in formula (1).
[0047]
[0048] Among them, SOC t is the state of charge of the energy storage unit at time t, used to indicate the remaining power of the energy storage unit; SOC0 is the initial state of charge of the energy storage unit; C is the rated capacity of the energy storage unit; η is the charge and discharge efficiency of the energy storage unit, η<1 during charging, and η=1 during discharging; I(i) is the current at time i, I is a positive value during charging, and I is a negative value during discharging.
[0049] It should be understood that the non-mains power unit includes: the solar energy unit, the wind energy unit and the power recovery unit. Whether the non-mains power unit has the power transmission capability can also be determined by calculating the charge state of the non-mains power unit according to formula (1).
[0050] In a preferred embodiment, the first charge threshold is set to 100%. It should be noted that the present application does not limit the specific size of the first charge threshold, and the user can set it according to needs.
[0051] Step S102: If the non-mains power unit still has the ability to transmit power, the non-mains power unit is controlled to transmit electric energy to the power conversion unit, and the power conversion unit converts the electric energy into electric energy of specified specifications and then transmits it to the energy storage unit for storage, so as to charge the energy storage unit until the charge state of the energy storage unit is equal to a preset first charge threshold, or the non-mains power unit no longer has the ability to transmit power.
[0052] Step S103: If the non-mains power unit does not have the power transmission capability, the mains power unit is controlled to transmit AC mains power to the power conversion unit, and the power conversion unit converts the AC mains power into electric energy of specified specifications and then transmits it to the energy storage unit for storage, so as to charge the energy storage unit until the charge state of the energy storage unit is equal to a preset first charge threshold.
[0053] In this embodiment, the control module preferentially selects a non-mains power unit to charge the energy storage unit according to the charge state of the energy storage unit, and can extend the charging time of the non-mains power unit, so that clean energy and recycled energy can be effectively utilized, thereby improving energy utilization, avoiding energy waste, and helping to reduce environmental pollution.
[0054] Furthermore, when the mains unit is selected to charge the energy storage unit, it is preferably done during the off-peak hours at night to reduce electricity costs and balance the mains load. Or when there is a high energy demand for electricity during long rainy, cloudy, or windless days, the mains unit is selected to charge the energy storage unit, which ensures the power supply of each power unit on the one hand, and reduces the use of mains electricity on the other hand, which is green and energy-saving.
[0055] In a specific embodiment, if Figure 3 As shown, the control module supplies power to each power-consuming unit according to the power demand of each power-consuming unit, including steps S201 to S204.
[0056] Step S201: Acquire the actual power consumption of each power-consuming unit in real time, and perform power consumption analysis on each power-consuming unit to obtain the power consumption demand of each power-consuming unit.
[0057] Step S202: Distinguish the power demand of each power-consuming unit and determine whether it includes a high-energy-consuming power demand.
[0058] Step S203: If high-energy-consuming electricity demand is not included, then when the charge state of the energy storage unit is greater than the preset second charge threshold, according to the non-high-energy-consuming electricity demand of each power unit, the power allocation unit is controlled to allocate electric energy from the energy storage unit to the power conversion unit, and the electric energy is converted into electric energy of the required specifications of each power unit by the power conversion unit and then transmitted to each power unit until the non-high-energy-consuming electricity demand of each power unit is met, or the charge state of the energy storage unit is less than the preset second charge threshold, and the energy storage unit is charged.
[0059] In one embodiment, when the control module meets the non-high-energy consumption electricity demands of each electricity-consuming unit, it can preset rules to give priority to meeting the electricity demands of convenience service type electricity-consuming units, and can set the order for meeting the electricity demands of other types of electricity-consuming units, thereby intelligently allocating electric energy and realizing centralized, unified and intelligent management of energy within the convenience service station.
[0060] It should be noted that the user can set the second charge threshold according to the needs, and the present application does not limit it. In a preferred embodiment, the present application sets the second charge threshold to 20%.
[0061] Step S204: If high energy consumption power demand is included, then when the charge state of the energy storage unit is greater than the preset third charge threshold, according to the high energy consumption power demand of each power unit, the power allocation unit is controlled to allocate power from the energy storage unit to the power conversion unit, and the power conversion unit converts the power into power of the required specifications of each power unit and then transmits it to each power unit until the high energy consumption power demand of each power unit is met, or the charge state of the energy storage unit is less than the preset third charge threshold, and the energy storage unit is charged.
[0062] In one embodiment, when the control module meets the high-energy consumption power demands of each power unit, it also presets rules to give priority to meeting the power demands of power units of convenience service type and sets the order of meeting the power demands of other types of power units.
[0063] It should be noted that the user can set the third charge threshold according to the needs, and the present application does not limit it. In a preferred embodiment, the present application sets the third charge threshold to 85%.
[0064] In this embodiment, the energy management system for the convenience service station described in this application can not only utilize other kinetic energy, especially clean energy, and convert it into electrical energy as electricity reserve, but also provide adaptive electrical energy for each power-consuming unit, and allocate electrical energy according to the power consumption and power demand of each power-consuming unit, thereby realizing centralized management, unified management and intelligent management of energy in the convenience service station, and ensuring the green and energy-saving operation of the convenience service station.
[0065] In a specific embodiment, if Figure 4 As shown, the control module sends warning information to the external operation center according to the health status of the energy storage unit, including steps S301 to S304.
[0066] Step S301: Calculate the health status of the energy storage unit in real time.
[0067] In one embodiment, the state of charge of the energy storage unit is calculated as shown in formula (2).
[0068] SOH=C n / C0×100%; (2)
[0069] Wherein, SOH is the health status of the energy storage unit; C0 is the initial rated capacity of the energy storage unit, that is, the amount of electricity that the energy storage unit can store under specific test conditions in an ideal state; C n It is the actual current available capacity of the energy storage unit, that is, the amount of electricity that the energy storage unit can currently store under the same test conditions.
[0070] Step S302: When the health status of the energy storage battery is less than a preset first health threshold, a first warning message is sent to an external operation center through the network communication module.
[0071] Step S303: When the health status of the energy storage battery is less than a preset second health threshold, a second warning message is sent to an external operation center through the network communication module.
[0072] Step S304: When the health status of the energy storage battery is less than a preset third health threshold, a third warning message is sent to an external operation center through the network communication module to prompt replacement of the energy storage unit.
[0073] When the health status of the energy storage battery drops to the third health threshold, the performance of the energy storage unit may have been severely degraded, and the energy storage unit needs to be replaced in time to avoid the inability to effectively store the electric energy transmitted by the energy input unit and to avoid frequent charging of the energy storage unit, thereby avoiding energy waste and achieving the purpose of high efficiency and energy saving. At the same time, it can also avoid the occurrence of safety accidents of the energy storage battery and ensure the safety of the energy management system used in the convenience service station.
[0074] In one embodiment, the first health threshold is set to 80%, the second health threshold is set to 70%, and the third health threshold is set to 60%. However, it should be noted that the present application is not limited thereto.
