With the development of technology, the demand for energy is also increasing. In order to reduce the carbon emission as much as possible while meeting the energy demand, renewable energy sources such as wind power generation, photovoltaic power generation and the like are required to be applied on a large scale. However, renewable energy sources have the property of unstable output, for example, when wind is weak or sunlight is absent, the corresponding wind power generation or photovoltaic power generation cannot stably output energy. In order to reduce the number of events that affect the safe operation of the power grid due to the unstable output of the renewable energy source, an Energy Storage System (ESS) is used to peak-adjust and frequency-adjust the power grid so as to stabilize the power grid.

The energy storage system refers to a highly concentrated energy storage device formed by placing a plurality of batteries in a cabinet body. The energy storage system typically includes a plurality of parallel battery clusters, each battery cluster consisting of a plurality of series-connected batteries. The battery may include, but is not limited to, a lithium ion battery, a lithium metal battery, a lead-acid battery, a nickel-metal-hydride battery, a nickel-metal hydride battery, a lithium-sulfur battery, a lithium-air battery, or a sodium ion battery, etc., and the scale of the battery may include, but is not limited to, a single battery, a battery module, a battery pack, etc. In practical applications, a single high-power conditioning converter (PCS) may convert dc power provided by a battery cluster into ac power, and further incorporate the ac power into a power grid.

The battery is sensitive to temperature, and when the temperature is too high, the service life of the battery is reduced. In order to control the temperature of the battery, a cooling mode of water cooling is generally adopted in the related art to cool the energy storage system, so that the battery in the energy storage system works in a reasonable temperature range as much as possible, and the influence on the service life of the battery caused by overhigh temperature of the battery is reduced. However, due to the low water cooling efficiency, there are still conditions in which the temperature of the battery is outside a reasonable temperature range throughout the operating conditions of the battery, and these conditions typically occur more often. That is, the temperature of the battery is reduced beyond a reasonable temperature range by cooling the water-cooled heat, which leads to a reduction in the service life of the battery, and the improvement degree is limited.

In order to reduce the frequency of occurrence of the condition that the temperature of the battery exceeds a reasonable temperature range in the whole operation working condition of the battery, improve the service life of the battery and further improve the service life of the energy storage system, one or more embodiments of the present application provide a thermal management control method.

The energy storage system disclosed in one or more embodiments of the present application includes, but is not limited to, use in peak clipping, valley filling, standby power, etc. Peak clipping and valley filling refers to the fact that an energy storage system is charged in a low-peak period of electricity consumption and discharged in a high-peak period of electricity consumption for users, so that the power supply pressure of a power grid in the high-peak period is relieved, and meanwhile, the utilization rate of the power grid in the low-peak period is improved. The standby power refers to actively disconnecting the power grid and constructing a micro-grid system under the condition that the power grid fails or the power grid fluctuates greatly, so that the energy storage is utilized to ensure the power supply of important loads.

One or more embodiments of the present application provide a thermal management control method that may be applied to an electronic device. The electronic device may comprise a terminal device or a server. The terminal device may be a mobile terminal such as a mobile phone, tablet computer, notebook computer, palm computer, PAD (Personal Digital Assistant ), etc., a fixed terminal such as a digital TV, desktop computer, etc.

As shown in fig. 1, the method may include the steps of:

step 101, determining an operation mode of the cooling equipment based on working condition parameters of the energy storage system; the working condition parameters are used for representing the current working condition of the energy storage system.

Step 102, controlling the cooling equipment to operate according to the operation mode.

In this embodiment, the current working condition of the energy storage system is the working condition of the battery in the energy storage system, so the reference battery generally has a standing working condition, a discharging working condition and a charging working condition, and the current working condition of the energy storage system includes the standing working condition, the charging working condition or the discharging working condition. The charging working condition refers to a process of charging the energy storage system to a charging cut-off voltage, the discharging working condition refers to a process of discharging the energy storage system to the discharging cut-off voltage, and the standing working condition refers to a process of neither discharging nor charging the energy storage system.

In this embodiment, for the charging condition and the discharging condition, in order to ensure the discharging efficiency, the requirement of the discharging end condition in the discharging condition for the reasonable temperature interval range is different from other conditions in the charging condition and the discharging condition, so that the operation mode of the cooling device can be determined for the two conditions respectively.

In this embodiment, parameters used for determining the current operating condition of the energy storage system include, but are not limited to, a state of charge (SOC, stateOfCharge) of the battery, a current variation parameter of the battery, and the like, and the current operating condition of the energy storage system can be determined by analyzing these parameters.

In this embodiment, the cooling device may include one or more cooling modules. Under the condition of comprising a cooling module, the operation mode of the cooling equipment characterizes the cooling effect of the cooling equipment. Under different operation modes, the cooling effect of the cooling equipment is different. The cooling effect under different operation modes can enable the energy storage system to operate in a reasonable temperature range interval as much as possible under different working conditions, and the occurrence times of events when the temperature of the energy storage system exceeds the reasonable temperature range are reduced. The current working condition of the energy storage system is exemplified by the discharge end working condition and the discharge initial working condition, and the cooling degree requirement of the energy storage system on the cooling degree is relatively higher than the cooling degree requirement of the energy storage system on the discharge initial working condition under the discharge end working condition, so that the cooling effect of the operation mode of the cooling equipment under the discharge end working condition is better than that of the operation mode of the energy storage equipment under the discharge initial working condition.

Under the condition that the cooling equipment comprises a plurality of cooling modules, the operation mode of the cooling equipment characterizes the operation state of each cooling module in the cooling equipment. The operation state herein includes, but is not limited to, a sleep state or an operation state, etc. The mechanism of cooling of different cooling modules in the cooling equipment is different, and the cooling effect of different cooling modules is also different, and these cooling modules both can independently cool down energy storage system, also can together operate together and cool down energy storage system. In application, the cooling module in the cooling device includes, but is not limited to, a heat dissipation module, a refrigeration module and the like. The heat dissipation module dissipates heat and cools the energy storage system through cooling liquid, and the refrigeration module cools the energy storage system by means of refrigerant.

In this embodiment, the operation mode of the cooling device may be determined based on a preset correspondence between the working condition and the operation mode. It should be understood that, in order to reduce the number of times that the temperature of the battery exceeds the reasonable temperature range interval as much as possible, and further reduce the influence on the service life of the battery, in the preset correspondence, the operation mode corresponding to a certain working condition may be the operation mode with the best refrigeration effect that the energy storage system can match under the working condition.

For example, the cooling device includes a cooling module, when the working condition is the working condition a, the working condition a may be matched with the working mode into two operation modes, i.e. a first mode and a second mode, and the cooling effect of the second mode is better than that of the first mode.

For example, when the working condition is B, the working condition B may be matched with the operation mode, which is a common operation mode for representing that the first cooling module and the second cooling module are cooled together, and a mode for representing that the first cooling module is cooled, and the cooling effect of the common operation mode of the first cooling module is as the latter.

In this embodiment, under the condition that the cooling device includes a plurality of cooling modules, the cooling device is controlled to operate according to the operation mode, and actually, the cooling module whose operation state is the operation state in the operation mode is controlled to operate through the control instruction set, and the cooling module whose operation state is the sleep state in the operation mode is controlled to sleep. The control instruction set comprises a plurality of control instructions, and each control instruction can correspond to one cooling module.

In this embodiment, in the case that the cooling device includes a plurality of cooling modules, in order to reduce the control overhead of the electronic device, a plurality of cooling modules in the cooling device may be further configured to be controlled by a unified unit host, so when the cooling device is controlled according to the operation mode, the electronic device only needs to interact with the unit host, and each cooling module in the cooling device interacts with the unit host.

In one or more embodiments of the present application, determining an operation mode of a cooling device based on a working condition parameter of an energy storage system may include the following steps:

In this embodiment, under certain conditions, the temperature parameter is used to represent the degree of demand of the energy storage system for cooling under such conditions, and the greater the temperature parameter is, the higher the degree of demand of the energy storage system for cooling is. That is, for a specific operating condition, the cooling device may be operated in a plurality of operating modes, and in which operating mode the cooling device is specifically operated, is determined by the temperature parameter included in the operating condition parameter. The greater the included temperature parameter, the higher the cooling degree of the operation mode determined by the working condition parameter.

In this embodiment, under different working conditions, there may be an overlap between the possible operation modes of the cooling device. For example, in the end-of-charge condition, the cooling device may operate in the first mode or the second mode based on a difference in temperature parameter included in the condition parameter. In the standing working condition, the cooling device can operate in the second mode or the third mode based on the difference of temperature parameters included in the working condition parameters. That is, there is an overlapping second mode between the end-of-charge condition and the rest condition, the possible modes of operation of the cooling device.

The foregoing description of various embodiments is intended to highlight differences between the various embodiments, which may be the same or similar to each other by reference, and is not repeated herein for the sake of brevity.

In one or more embodiments of the present application, determining an operation mode of the cooling device based on the operating condition and the temperature parameter included in the operating condition parameter may include the following steps:

In this embodiment, the system temperature of the energy storage system refers to the temperature of the energy storage system itself, which is used to characterize the magnitude of the thermal load of the energy storage system. The thermal load herein refers to a load that causes heat to be generated by a battery within the energy storage system. In application, the system temperature of the energy storage system includes, but is not limited to, as a function of the temperature of the cells in the energy storage system.

In this embodiment, under the condition of the end-stage discharging condition, on one hand, in order to ensure that the energy storage system has higher discharging efficiency, the system temperature of the energy storage system is usually allowed to be slightly higher than a reasonable temperature range, and on the other hand, under the condition, since the system temperature of the energy storage system is itself higher, the influence of the environmental temperature of the environment where the energy storage system is located on the energy storage system is smaller than the system temperature. In order to simplify the calculation amount controlled by the thermal management system, the operation mode of the cooling device is determined temporarily without reference to the ambient temperature under the working condition.

In one or more embodiments of the present application, determining an operation mode of a cooling device based on a system temperature of an energy storage system included in a temperature parameter may include the steps of:

Under the condition that the system temperature is less than or equal to a first system temperature threshold value, determining that the operation mode of the cooling equipment is a common operation mode, wherein the common operation mode is a mode of common cooling through a refrigerating module and a radiating module in the cooling equipment;

and under the condition that the system temperature is greater than the first system temperature threshold value, determining that the operation mode of the cooling equipment is a mode of cooling through the refrigerating module.

It should be understood that the system temperature being less than or equal to the first temperature threshold means that the system temperature is less than or equal to the first temperature threshold.

In this embodiment, a system temperature less than or equal to the first system temperature threshold indicates that the thermal load of the energy storage system is small. Accordingly, a system temperature greater than the first system temperature threshold indicates a greater thermal load on the energy storage system.

In this embodiment, the first system temperature threshold includes, but is not limited to, manually preset based on experience or according to actual requirements.

It should be understood that heat dissipation and cooling of the heat dissipation module generally refers to heat exchange between the energy storage system and air through the cooling liquid, that is, the heat exchange between the energy storage system and the cooling liquid is performed, and the cooling liquid and the air are further subjected to heat exchange, so that cooling of the energy storage system is achieved, which is a spontaneous heat exchange process, so that the cooling effect of the heat dissipation module is limited by a temperature difference between the temperature of the environment and the temperature of the system of the energy storage system. And for the refrigeration module, the energy storage system is cooled by the refrigerant, in particular, the temperature of the refrigerant is reduced in the refrigeration module to obtain low-temperature refrigerant, and the low-temperature refrigerant realizes heat exchange with the energy storage system. The temperature of the refrigerant in the refrigerating module is reduced, and the refrigerant does not automatically exchange heat with air, but does work through refrigerating equipment in the refrigerating module, so that the temperature of the refrigerant can be reduced to a lower degree according to requirements. Comparing the two modes, the cooling effect of the cooling mode can be far better than that of the heat dissipation module. In this embodiment, therefore, it is considered that the cooling effect corresponding to the mode of cooling by the cooling module is higher than that of the common operation mode.

In this embodiment, whether in the common operation mode or the cooling mode by the cooling module, the operation parameters of the cooling module are preconfigured, and after determining which cooling module is adopted to cool, the cooling module can be controlled to operate according to the preconfigured parameters. For example, under the working condition of the end stage of discharge, the parameters of the cooling device operated in the cooling mode through the cooling module are preset as the first cooling parameters, and the parameters operated in the common operation mode are the second cooling parameters and the first heat dissipation parameters, so in the process of executing the thermal management control method, if the working condition of the energy storage system is determined to be the working condition of the end stage of discharge and the determined operation mode of the cooling device is the common operation mode, the heat dissipation module operates according to the first heat dissipation parameters when the cooling device operates, and the cooling module operates according to the second cooling parameters.

In application, the refrigeration parameters of the corresponding refrigeration module include, but are not limited to, parameters representing the refrigeration speed, parameters representing the quantity of refrigeration at each time, and the like; the heat dissipation parameters of the corresponding heat dissipation module include, but are not limited to, parameters representing heat dissipation speed, parameters representing how much heat is dissipated each time, and the like.

In this embodiment, the remaining operating conditions include, but are not limited to, an initial discharge operating condition, a mid discharge operating condition, a charge operating condition, or the like. The charging working condition comprises an initial charging period, a middle charging period and an end charging period.

In order to reduce the impact on the service life of the energy storage system when the working condition of the energy storage system is the remaining working condition, the temperature of the energy storage system is usually required to be within a reasonable temperature interval. The temperature in the temperature interval range may be slightly different from the ambient temperature, so that the ambient temperature can also affect the cooling requirement of the energy storage system, and the influence of the influence on the cooling requirement of the energy storage system by the system temperature relative to the system temperature of the energy storage system cannot be ignored, so that under the condition of the residual working condition, the matching degree of the determined running mode and the residual working condition can be improved by referring to the ambient temperature, and the effect of enabling the system to have smaller power consumption as much as possible on the basis of reducing the influence on the service life by cooling is achieved.

In one or more embodiments of the present application, the operating conditions include a resting condition; determining an operational mode of the cooling device based on the ambient temperature included in the temperature parameter and the system temperature of the energy storage system may include the steps of:

under the condition that the system temperature is greater than the second system temperature threshold and the environment temperature is greater than the first environment temperature threshold, determining that the operation mode of the cooling equipment is a common operation mode, wherein the common operation mode is a mode of common cooling through a refrigerating module and a radiating module in the cooling equipment;

and under the condition that the system temperature is greater than the second system temperature threshold and the ambient temperature is less than or equal to the first ambient temperature threshold, determining that the operation mode of the cooling equipment is a mode of radiating heat through the heat radiating module.

In this embodiment, the second system temperature threshold includes, but is not limited to, manually preset based on experience or according to actual requirements.

In this embodiment, the second system temperature threshold is generally less than the first system temperature threshold because the energy storage system is typically thermally loaded during end-of-discharge conditions and is typically thermally unloaded during rest conditions.

In this embodiment, the system temperature or ambient temperature under the rest condition includes, but is not limited to, being expressed in terms of a mean value, a maximum value, etc. of the temperature under the whole condition. By way of example, the system temperature of the energy storage system under the standing condition can be represented by the average value of the system temperature under the whole standing condition. The system temperature or the ambient temperature in the end-of-discharge condition and other conditions in the remaining conditions can also be determined in this way, so as to prevent redundancy and avoid further description.

In application, the standing working condition of the energy storage system is usually switched from a charging working condition or a discharging working condition, that is, before the energy storage system is in the standing working condition, the energy storage system is in the charging working condition or the discharging working condition, and after the charging working condition or the discharging working condition is finished, the energy storage system is in the standing working condition. Therefore, the system temperature of the energy storage system in the standing condition can be actually understood as the system temperature left by the charging condition or the discharging condition. For example, after the discharging working condition is ended, the energy storage system has the first system temperature, and after the discharging working condition is ended, the energy storage system does not actually carry the heat load and the first system temperature can be attenuated, but in the whole standing working condition, the system temperature of the energy storage system is not completely 0, so the energy storage system still has the system temperature under the standing working condition.

In this embodiment, the system temperature is less than or equal to the second system temperature threshold value, which characterizes that the thermal load of the energy storage system is small. Accordingly, a system temperature greater than the second system temperature threshold is indicative of a greater thermal load of the energy storage system.

In this embodiment, under the condition of smaller thermal load, in order to make the energy storage system have a higher temperature under the working condition of the later discharge end, the discharge efficiency is improved, and the power consumption of the system is saved, so that the cooling device is set to operate in the sleep mode.

In this embodiment, the environmental temperature is greater than the first environmental temperature threshold to represent that the environmental temperature is higher, and the higher environmental temperature also aggravates the rise of the system temperature of the energy storage system, so that under this condition, the cooling device is operated in the common operation mode, and the purpose of timely and rapid cooling can be achieved. And when the ambient temperature is smaller than or equal to the first ambient temperature threshold value and the representation ambient temperature is lower, the ambient temperature can not aggravate the rise of the system temperature of the energy storage system, so that the cooling equipment operates in a mode of radiating through the radiating module under the condition, the cooling equipment can not only play a role in cooling to reduce the influence on the service life of the energy storage system, but also reduce the power consumption of the system and save energy.

In this embodiment, the first ambient temperature threshold includes, but is not limited to, being preset based on experience by human or according to actual requirements.

In one or more embodiments of the present application, the operating conditions include a charging operating condition or an initial discharging operating condition; determining an operational mode of the cooling device based on the ambient temperature included in the temperature parameter and the system temperature of the energy storage system may include the steps of:

determining that the operation mode of the cooling equipment is a mode of cooling through a refrigerating module in the cooling equipment under the condition that the system temperature is greater than a third system temperature threshold value and the environment temperature is greater than a second environment temperature threshold value;

And under the condition that the system temperature is greater than a third system temperature threshold and the environmental temperature is less than or equal to a second environmental temperature threshold, determining that the operation mode of the cooling equipment is a common operation mode, wherein the common operation mode is a mode of cooling through a refrigerating module and a radiating module in the cooling equipment.

In this embodiment, the system temperature is less than or equal to the third system temperature threshold, which characterizes that the thermal load of the energy storage system is small. Accordingly, a system temperature greater than the third system temperature threshold indicates a greater thermal load of the energy storage system. The third system temperature threshold is less than the first system temperature threshold and greater than the second system temperature threshold.

In this embodiment, the environmental temperature is greater than the second environmental temperature threshold to represent that the environmental temperature is higher, and the higher environmental temperature also aggravates the rise of the system temperature of the energy storage system, so in this case, the cooling device is operated in a mode of refrigerating by the refrigerating module, and the purpose of timely and rapid cooling can be achieved. And when the environmental temperature is smaller than or equal to the second environmental temperature threshold value and the representation environmental temperature is lower, the environmental temperature can not aggravate the rise of the system temperature of the energy storage system, so that the cooling equipment operates in a common operation mode under the condition, the cooling equipment can not only play a role in reducing the influence on the service life of the energy storage system, but also reduce the power consumption of the system and save energy.

It should be appreciated that the charging or discharging initial conditions are different from the rest conditions in that the energy storage system is typically operated without a thermal load during the rest conditions, and the energy storage system is typically operated with a thermal load during the charging or discharging initial conditions, where the cooling requirements are different. The corresponding demand degree under the charging working condition or the discharging initial working condition is characterized by the refrigeration degree corresponding to the common operation mode and the refrigeration mode through the refrigeration module, and the corresponding demand degree under the standing working condition is characterized by the common operation mode and the refrigeration degree corresponding to the heat dissipation module.

In this embodiment, the second environmental temperature threshold value includes, but is not limited to, manually preset based on experience or preset according to actual needs. Wherein the second ambient temperature threshold is greater than the first ambient temperature threshold.

In one or more embodiments of the present application, controlling the cooling device to operate according to an operation mode may include the following steps:

controlling a conveying pipeline of a target module in cooling equipment to form a fluid conveying loop, wherein the target module is a collection of components responding to an operation mode in the cooling equipment, and the conveying pipeline passes through an energy storage system;

Wherein the gas may include, but is not limited to, air. Liquids include, but are not limited to, water, saline, and the like.

In this embodiment, the delivery loop passes through the energy storage system and the target module. The fluid circulates in the delivery circuit. When the fluid flows through the target module, the fluid exchanges heat with the target module, and the heat of the target module is transferred to the fluid, so that the temperature of the target module is increased, and the temperature of the fluid is reduced. When the fluid with lower temperature flows through the pipeline at the position of the energy storage system, the fluid exchanges heat with the energy storage system, heat in the energy storage system is transferred to the fluid, so that the temperature of the fluid rises, and the temperature of the energy storage system drops. The fluid with the temperature rising flows back to the target module for heat exchange, and the heat exchange is circularly performed, so that the temperature of the energy storage system is reduced, and the effect of prolonging the service life of the energy storage system is achieved.

The line regulation assembly 201 may include, but is not limited to, a two-way valve, a three-way valve, and the like.

In this embodiment, the fourth conveying line 209 is connected in parallel with the first conveying line 203, so that in the case where both the heat dissipating module and the refrigerating module are operated, the fluid in the fourth conveying line 209 and the first conveying line 203 exchange heat with the energy storage system 204 via the second conveying line 205.

In this embodiment, the fluid in the first conveying line 203 and the fluid in the fourth conveying line 209 are the same, and are both cooling liquids. The fluid in the third transfer line 208 may be a refrigerant. In applications, the cooling fluid includes, but is not limited to, water, brine, and the like. Refrigerants include, but are not limited to, refrigerants employing components such as R134A or R410A.

The heat exchange here means that the fluid in the fourth transfer line 209 transfers heat to the third transfer line 208, the fluid in the third transfer line 208 increases in temperature, and the fluid in the fourth transfer line 209 decreases in temperature.

In this embodiment, in order to improve the cooling efficiency, a fan may be provided on the condenser included in the cooling unit 207.
