Example 1
Fig. 1 is a block diagram of a battery temperature adjustment system according to an embodiment of the present application, where the system may be disposed in an energy storage container, and the system may be adapted to perform temperature control on a battery of the energy storage container.
As shown in fig. 1, the system 100 includes: a temperature control unit 110 and at least two temperature control branches 120; each temperature control branch 120 comprises a water inlet pipeline 121, a water distribution pipeline 122, a battery cooling pipeline 123, a water collecting pipeline 124 and a water outlet pipeline 125 which are sequentially arranged in an end-to-end manner; the water inlet of the water inlet pipeline 121 of each temperature control branch is connected with the water outlet of the temperature control unit 110; the water outlet of the water outlet pipeline 125 of each temperature control branch is connected with the water inlet of the temperature control unit 110; the battery cooling line 123 includes a liquid cooling plate cluster 01 and at least two cooling communication tubes 02; the liquid cooling plate cluster 01 is arranged in a manner of being attached to the battery cluster 00 to be temperature controlled; the liquid cooling plate cluster 01 is arranged in the temperature control branch 120 in series through the cooling communicating pipe 02; the water diversion pipeline 122 comprises a water diversion pipeline 11 and a flow valve 12; the flow valves 12 are installed in the water diversion pipeline 122 in an embedded manner, and each flow valve 12 is electrically connected with an input/output interface (I/O port) of the temperature control unit 110.
It should be noted that the temperature control unit may be any device capable of providing cooling liquid for the temperature control branch, and of course, the cooling liquid provided by the temperature control unit is not only used for cooling, but also used for heating, that is, the temperature control unit controls the temperature of the cooling liquid, so that the cooling liquid cools or heats the battery of the energy storage container through different temperature control branches, so as to ensure the effective working temperature range of the battery, thereby exerting the normal battery performance. The temperature control unit may adopt more mature hardware in the related technology, and the embodiment of the application is not limited to this.
Alternatively, the liquid cooling plate cluster 01 may include at least two cell liquid cooling plates a. Further, the liquid cooling plate cluster 01 is attached to the battery cluster 00 to be temperature controlled, and may include: each battery liquid cooling plate A is respectively attached to different batteries B in the battery cluster 00 to be temperature controlled.
It will be appreciated that the individual cells in the energy storage container are mounted in the form of battery packs, which are arranged in clusters, i.e. clusters of cells to be temperature controlled. And each battery in the battery cluster to be temperature-controlled is tightly provided with a liquid cooling plate, so that the contact area between the cooling liquid and the battery is increased when the cooling liquid passes through the liquid cooling plate, and the cooling or heating efficiency is improved. Then, the liquid cooling plates arranged on each battery in a pasting way form a liquid cooling plate cluster along with the battery cluster to be temperature-controlled.
Further, the liquid cooling plate cluster 01 is serially connected to the temperature control branch 120 through the cooling communication pipe 02, which may include: each cooling communicating pipe 02 is formed by sequentially connecting each battery liquid cooling plate A in series to form a battery cooling pipeline, and the battery cooling pipeline is arranged in the temperature control branch.
It will be appreciated that since each battery is configured with a battery cooling plate, the manner of connection between the different cooling plates can have an impact on the efficiency of temperature control. According to the embodiment of the application, a series connection mode is adopted, and the battery liquid cooling plates in the same liquid cooling plate cluster are connected in series end to end in sequence through each cooling connecting pipe, namely, the cooling liquid in the current liquid cooling plate can directly flow into the next liquid cooling plate.
Further, the flow valve 12 is used to open or close according to the control signal of the temperature control unit 110. The flow valve is disposed in the water distribution pipeline 122, so as to open the water distribution pipeline, and it is conceivable that, due to the existence of a plurality of temperature control branches, when different temperature control strategies are needed for different battery clusters to be controlled, the flow valve can be controlled to be opened or closed, so that separate temperature control is performed on different battery clusters. Of course, the flow valve is electrically connected with the temperature control unit, so that not only can the control signal of the temperature control unit be received, but also the state signal (opened or closed) of the flow valve can be fed back to the temperature control unit, and the control flexibility and accuracy are improved. Of course, the flow valve 12 may also be disposed in the water collecting pipeline 124, and the water collecting pipeline are provided with flow valves, so that flexibility of controlling the flow of the cooling liquid is further enhanced.
Optionally, the system 100 may further comprise at least two temperature sensors C; wherein, each temperature sensor C is respectively arranged in different battery clusters 00 to be controlled in temperature and is arranged in a way of being attached to the battery B in the battery cluster to be controlled in temperature. Further, each temperature sensor C is electrically connected to an input/output interface of the temperature control unit 110. The temperature sensor C is configured to detect a temperature of the battery cluster 00 to be controlled, and send a temperature signal to the temperature control unit 110.
The temperature sensor can be arranged in each battery cluster to be controlled, for example, on any battery pack in the battery cluster to be controlled, and is arranged to be attached to the battery so as to accurately detect the temperature of the battery; of course, the temperature sensor may be installed on each battery in all the battery clusters to be controlled, which is not limited in the embodiment of the present application. The temperature sensor is electrically connected with the input/output interface of the temperature control unit, and can timely send temperature signals to the temperature control unit, so that the temperature control unit can reasonably allocate cooling liquid according to the temperature conditions of different battery clusters.
Correspondingly, the temperature control unit 110 is configured to receive the temperature signal, and send a control signal to the flow valve 12 according to the temperature signal, so as to control the flow valve 12 to be opened or closed. And, the temperature control unit 110 adjusts the output coolant temperature according to the temperature.
For example, when the temperature sensor detects that the battery temperature in the corresponding battery cluster deviates from a preset range value (such as 15-35 ℃), the temperature control unit can pump the cooling liquid with lower temperature according to the overhigh battery temperature (more than or equal to 35 ℃); and in the same way, the temperature control unit can pump heating liquid with higher temperature according to the excessively low temperature (less than or equal to 15 ℃) of the battery.
Correspondingly, the temperature control unit can comprise a control module, a cooling liquid temperature control module and a water pump; the control module at least comprises a processor, a memory and an input/output interface, and is electrically connected with the input/output interface of the temperature control unit, namely the input/output interface of the control module. The cooling liquid temperature control module is used for cooling or heating the cooling liquid to be pumped. The water pump pumps the cooling liquid, so that the cooling liquid circulates through the temperature control unit and each temperature control branch. It should be noted that the cooling liquid may be water, or any other liquid substance for heat conduction.
It should be further explained that, in the technical scheme of this application embodiment, will be with the different liquid cooling boards that belong to in the liquid cooling board cluster establish ties through cooling communicating pipe for the coolant liquid can flow through in proper order between each liquid cooling board that links to each other, and the mode of establishing ties makes flow and the velocity of flow through every liquid cooling board tend to the same and stable, compares parallelly connected mode and can improve flow and velocity of flow, thereby improves battery temperature control's efficiency, just also practiced thrift resources such as electric energy and water that the cooling needs. And compared with a parallel mode, the serial connection of each liquid cooling plate can reduce the number of pipelines and the number of connecting plug-ins in the pipeline, thereby saving the manufacturing cost of the container and reducing the risk of leakage of cooling liquid.
Example two
Fig. 2 is a flowchart of a battery temperature adjusting method according to a second embodiment of the present application, where the embodiment of the present application provides a battery temperature adjusting method based on the battery temperature adjusting system according to the foregoing embodiment. The method can be applied to a temperature control unit in a battery temperature regulating system. As shown in fig. 2, the method includes:
s210, acquiring temperature signals of the temperature sensors.
The temperature sensors can be temperature sensors arranged on the adjacent batteries in any battery cluster to be controlled, and temperature signals can be detected and acquired in real time for all the temperature sensors.
S220, determining at least one target battery cluster needing to be temperature-adjusted according to the temperature signals and a preset temperature control threshold value.
The preset temperature control threshold value may be a normal working temperature of the battery, if the temperature sensor detects that the temperature signal of the battery cluster to be controlled indicates that the battery temperature is not within a preset temperature control threshold value (for example, the temperature is 15-35 ℃) range, the battery cluster to be controlled corresponding to the temperature signal is determined to be a target battery cluster, and the target battery cluster is the battery cluster to be controlled, which needs to be temperature-adjusted.
S230, controlling the opening or closing of different flow valves according to at least one target battery cluster, and acquiring state signals of the flow valves.
Wherein the status signal of the flow valve may be indicative of the status of the opening or closing of the flow valve. The temperature control unit can control the opening and closing of the flow valve according to all the target battery clusters determined in the previous steps. Because each battery cluster is provided with a group of liquid cooling plate clusters corresponding to the battery clusters, each group of liquid cooling plate clusters is provided with only one water distribution pipeline connected with the liquid cooling plate clusters, and then flow valves in the water distribution pipeline are in one-to-one correspondence with the target battery clusters. And according to the target battery cluster determined in the previous step, determining that the corresponding flow valve is opened, and closing the flow valve for the opposite use without the need of temperature control of the battery cluster. And the temperature control unit can acquire signals of the on-off states of the flow valves, so that the states of the flow valves can be accurately acquired, and the problems of timely water supply or timely damage of the flow valves can be facilitated.
S240, determining temperature regulation parameters of the temperature control unit according to the temperature signals and at least one target battery cluster.
The temperature adjustment parameter may be a processing parameter of the temperature control unit on the cooling liquid, for example, may include an output cooling liquid temperature, a flow rate and a power that need to be provided when the cooling liquid is pumped, and the like. These temperature adjustment parameters may help the temperature control unit provide a basis for adjusting the temperature of the cooling fluid and pumping the cooling fluid.
In an alternative embodiment, the temperature adjustment parameters include a coolant temperature, a pumping flow rate, and an output power, and determining the temperature adjustment parameters of the temperature control unit according to the temperature signal and the at least one target battery cluster may include: and determining the temperature of the cooling liquid, the pumping flow and the output power according to the temperature signal and the number of the target battery clusters.
Of course, when detecting whether the battery cluster needs to be cooled or heated, a plurality of target battery clusters needing to be temperature-adjusted are easy to detect, and then according to the temperature signals and the number of the target battery clusters, the temperature of the cooling liquid, the output flow and the output power of the temperature control unit when the cooling liquid is pumped are correspondingly determined. In general, the greater the number of target clusters, the greater the pump flow and output power; the temperature of the coolant is determined according to the specific conditions of the battery temperature.
S250, according to the state signals of the flow valves and the temperature adjustment parameters, the temperature of the cooling liquid is adjusted and pumping is carried out, so that the temperatures of different target battery clusters are adjusted.
According to the state signal of the flow valve obtained in the previous step, the pumping time of the cooling liquid can be determined, for example, after the flow valve is opened, the cooling liquid is pumped. The coolant is treated (including temperature regulation) according to the various temperature regulation parameters determined in the previous steps, and then pumped at a determined flow rate and power. The cooling liquid can smoothly circulate in the liquid cooling plate cluster corresponding to the target battery cluster, and the temperature of the battery is adjusted.
Optionally, after the temperature of the cooling liquid is adjusted and pumped according to the temperature adjustment parameter, the method may further include: and if the temperature signals of the temperature sensors change, adjusting the temperature adjustment parameters according to the change amount of the temperature signals and a preset temperature control threshold value.
Because the temperature sensor detects in real time, if the signal of the temperature sensor is found to change in the process of pumping the cooling liquid, the corresponding temperature adjustment parameter also needs to be changed, so as to help the temperature control unit to accurately and timely adjust the temperature control strategy.
For example, if the temperature of the target battery cluster does not meet the preset temperature control threshold value, the temperature of the pumped cooling liquid is adjusted to meet the preset temperature control threshold value, whether the cooling or heating is necessary to be continued is judged according to the temperature condition of the target battery, so that the temperature adjustment parameter is changed.
Of course, other situations may also occur, for example, in the process of pumping the cooling liquid, the problem that other battery clusters are detected to be out of the current target battery cluster does not meet the preset temperature control threshold value, which is equivalent to the occurrence of a new target battery cluster needing to be temperature controlled, and then, correspondingly, each temperature adjustment parameter is changed, the corresponding flow valve is opened, and the temperature adjustment is performed on the new target battery cluster.
According to the technical scheme of the embodiment of the application, by means of the battery temperature adjusting system of the embodiment, the battery clusters needing to be temperature-adjusted are flexibly supplied with cooling liquid by monitoring the temperature of the battery, the flow of the corresponding liquid cooling plate clusters is accurately controlled, and the temperature adjusting efficiency is improved; meanwhile, the temperature control unit can also effectively reduce the energy consumption of the temperature control unit through stepless variable frequency output, and reduce the electric energy loss in the battery thermal management process, so that the cost of battery thermal management is further reduced.
