However, when integrating these energy devices into a set of energy systems, it is challenging to centrally manage these energy devices so that the power consumption of the whole set of energy systems is reduced. Therefore, the embodiment provides an energy gateway device, which is in communication connection with a plurality of energy devices, so as to communicate with the plurality of energy devices, and can intelligently control the working modes of each energy device in an energy system. Typically, the energy system is capable of providing a systematic energy service scheme to end users, which in one example may include, but is not limited to, building energy systems, vehicle energy systems, and the like.

In one possible implementation manner, the energy system includes a plurality of energy devices, and the control priority of the energy devices can be set in advance according to an actual application scene, and when the parameter values are obtained and the working modes of the energy devices are adjusted, the parameter values of the power consumption parameters corresponding to the plurality of energy devices are sequentially obtained according to the control priority, and the corresponding energy devices are controlled to switch to the target working mode. In one example, considering that the parameter value of the power consumption parameter of the energy device may change continuously, the acquisition timing of the parameter value may be set according to the attribute of the parameter value of the power consumption parameter of different energy devices, for example, the parameter value may be acquired once and the operation mode may be adjusted, the parameter value may be acquired periodically and the operation mode may be adjusted periodically, and the parameter value may be continuously acquired and the operation mode may be adjusted according to the acquired parameter value.

In one example, the power consumption modes of the energy device may include a low power consumption mode and a non-low power consumption mode, the trigger signal for switching to the low power consumption mode may include, but is not limited to, any one of a trigger signal actively sent by a user through the interaction device and a trigger signal sent when the output power of the power conversion device corresponding to the power consumption load is smaller than a preset threshold, where when the output power of the power conversion device corresponding to the power consumption load is smaller than the preset threshold, the corresponding power consumption load may be considered to be not in a use state, and when the output power of the power conversion device corresponding to the power consumption load is continuously smaller than the preset threshold within a preset duration, the power consumption load in the energy system may be considered to be not in a use state for a long time, and the standby power consumption of the power conversion device may be controlled to switch the energy system to the low power consumption mode. The trigger signal for switching to the non-low power consumption mode may include, but is not limited to, a trigger signal actively sent by a user through an interactive device, a start signal of a device in the energy system, and the like, and the interactive device may include, but is not limited to, a display screen, a physical key, and a mobile terminal.

Step S120, determining a target working mode of the energy device, which is matched with the preset power consumption mode, the energy device, and the parameter value of the power consumption parameter;

specifically, after the parameter value of the power consumption parameter corresponding to the energy equipment is obtained, the target working mode corresponding to the energy equipment at the moment can be determined and obtained according to the energy equipment, the preset power consumption mode and the parameter value. In general, different kinds of energy devices may correspond to different operation modes, for example, the operation modes of the charging controller and the electric load may correspond to an on mode and an off mode; the operation modes of the energy storage battery may correspondingly include a charge mode, a discharge mode, and a shutdown mode. In this embodiment, the energy device corresponds to different working modes according to different power consumption parameter values in different power consumption modes, that is, the target working mode, and in different power consumption modes, the association relationship between the power consumption parameter values of the energy device and the working modes may be obtained in advance according to actual application scenarios.

And step S130, controlling the energy source equipment to switch to the target working mode.

Specifically, after the target working mode of the energy equipment is determined, the energy equipment is controlled to be switched to the target working mode, and when the working mode of the energy equipment is the same as the target working mode, the working mode of the energy equipment can be kept unchanged. The energy gateway device can send a working mode switching signal to the corresponding energy device through communication connection with the energy device, so that the energy device can be switched to the corresponding working mode according to the working mode switching signal. In one example, when the plurality of energy devices have a preset control priority, the plurality of energy devices are sequentially controlled to switch to the target working mode according to the control priority.

The embodiment of the disclosure provides a power consumption control method of an energy system applied to an energy gateway device, the energy gateway device is in communication connection with a plurality of energy devices in the energy system, the plurality of energy devices at least comprise a charging controller, an electricity load and an energy storage battery, the parameter values of power consumption parameters corresponding to the energy devices are obtained in response to a trigger signal for switching to a preset power consumption mode, the target working mode corresponding to the energy devices can be determined according to the preset power consumption mode, the energy devices and the parameter values, the energy devices are controlled to be switched to the target working mode, and when the power consumption mode of the energy system is switched, the working modes of the energy devices in the energy system can be determined and adjusted according to the preset power consumption mode and the parameter values of the energy devices, so that systematic unified control of the energy devices in the energy system is realized, the condition of high power consumption caused by independent control of single energy devices is reduced, the whole energy consumption of the energy system is saved, and the normal operation of the energy system is prevented from being influenced by insufficient energy.

Step S121, acquiring an association relationship between a parameter value of a power consumption parameter matched with the energy device in the preset power consumption mode and a working mode of the energy device;

step S122, determining a target working mode of the energy device according to the parameter value of the power consumption parameter based on the association relationship.

In the embodiment of the disclosure, when determining the target working mode of the energy device, because the power consumption parameter values of the energy device in different power consumption modes may correspond to different association relations between the working modes, the association relation between the parameter values of the power consumption parameters of the energy device and the working modes in the preset power consumption mode corresponding to the trigger signal is obtained. The association relationship between the parameter value of the power consumption parameter of the energy device and the working mode may be obtained in advance according to the actual application scenario. When the working modes of a plurality of energy devices in the energy system are controlled, corresponding association relations are acquired according to the energy devices, in one example, different association relations can be correspondingly set between parameter values of different types of energy devices and the working modes, and further, different association relations can be correspondingly set for each energy device. And determining a target working mode of the energy equipment according to the acquired parameter values of the power consumption parameters based on the determined association relation. In one example, when the association relationship is set, the association relationship in different power consumption modes can be set according to the influence of different energy devices in different working modes on the power consumption of the energy system.

According to the embodiment of the disclosure, the target working mode corresponding to the parameter value is determined according to the obtained association relation between the parameter value of the power consumption parameter of the energy device in the preset power consumption mode and the working mode, so that the target working mode can be determined according to the energy device and the parameter value in different power consumption modes based on the association relation, the matching of the power consumption mode, the energy device and the parameter value of the power consumption parameter with the working mode is realized, and the control flow of the energy device is simplified; according to the power consumption mode of the energy system, the working mode of the energy equipment in the energy system is controlled, unified control and regulation of the power consumption of the energy system are efficiently and quickly realized, the energy consumption is reduced, the energy utilization rate of the energy system is improved, and the influence on the normal operation of the energy system due to energy deficiency is avoided.

In an embodiment of the present disclosure, the energy system includes a plurality of energy storage batteries, and taking an energy system of a caravan as an example, the plurality of energy storage batteries may include a start battery and a living battery of the caravan. When the working modes of the plurality of energy storage batteries are adjusted, the residual electric quantity value of each energy storage battery in the plurality of energy storage batteries is obtained, and the target working mode of the plurality of energy storage batteries in the preset power consumption mode is determined according to the obtained residual electric quantity value, wherein the working modes of the energy storage batteries comprise at least one of a charging mode, a discharging mode and a closing mode. In one example, a bi-directional charger (e.g., a DC-DC bi-directional charger) is provided between the plurality of energy storage batteries to enable transfer of charge between the batteries. In one possible implementation manner, the electric quantity threshold value may be set according to an actual application scene, different energy storage batteries may correspond to different electric quantity threshold values, and the corresponding target working state is determined according to a relationship between the remaining electric quantity of the energy storage battery and the corresponding electric quantity threshold value. With the switching and running of the working modes of the energy storage battery, the residual electric quantity value of the energy storage battery changes along with time and application scenes, and in one possible implementation manner, the residual electric quantity value of the energy storage battery can be periodically obtained in response to a trigger signal for switching to a preset power consumption mode, a corresponding target working mode is determined according to the residual electric quantity value, and the working mode of the energy storage battery is periodically adjusted and switched; the method can also continuously acquire the residual electric quantity value of the energy storage battery, determine the corresponding target working mode according to the residual electric quantity value, and adjust and switch the working mode of the energy storage battery.

In one example, the energy storage batteries are used for supplying power to the whole energy system, the power supply purposes of the different energy storage batteries are different, so that the relation between the residual electric quantity and the working mode of the energy storage batteries can be set, the method described in the embodiment is applied to the vehicle energy system, the vehicle energy system can be set to be a double-battery system, one energy storage battery is used for supplying power to an original vehicle load (such as a driving lamp, an ignition system, an audio-visual system and the like) of the vehicle, one energy storage battery is used for supplying power to living electric equipment (such as a refrigerator, an air conditioner and the like) in the vehicle, and a bidirectional charger is arranged between the two energy storage batteries. The energy storage battery corresponding to the original vehicle load is recorded as a front vehicle battery, the energy storage battery corresponding to the life electric equipment is recorded as a rear vehicle battery, and the electric quantity of the front vehicle battery cannot be too low in consideration of normal use of the vehicle. When the working modes of the energy storage battery are adjusted, the residual electric quantity of the front car battery and the residual electric quantity of the rear car battery are obtained, the working modes of the front car battery and the rear car battery under a preset power consumption mode are determined according to the residual electric quantity, for example, when the residual electric quantity of the front car battery is smaller than a corresponding first electric quantity threshold value, the residual electric quantity of the front car battery is considered to be lower at the moment, if the residual electric quantity of the rear car battery is larger than a corresponding second electric quantity threshold value, the electric quantity of the rear car battery can be used for supplementing the front car battery, the target working mode of the rear car battery is determined to be a discharging mode at the moment, the target working mode of the front car battery is determined to be a charging mode, the first electric quantity threshold value and the second electric quantity threshold value can be set according to an actual application scene, the front car battery and the rear car battery can be controlled to be switched to the target working mode through a wake-up bidirectional charger, and the rear car battery can charge the front car battery through the bidirectional charger. In one example, when the rear vehicle battery supplements the front vehicle battery with electricity, the residual electricity values of the front vehicle battery and the rear vehicle battery are periodically obtained, and when the residual electricity value of the front vehicle battery is greater than or equal to the first electricity threshold value, the rear vehicle battery stops supplementing the front vehicle battery with electricity. In one example, the remaining capacity of the battery may be determined by acquiring a battery voltage or the like.
