[0030] In order to facilitate the understanding of the embodiments, first, a kind of intelligent liquid cooling control method disclosed by the embodiments of the present application is introduced in detail.

[0031] Embodiment 1

[0032] The embodiments of the present application provide an intelligent liquid cooling control method, Figure 1 A flowchart of the intelligent liquid cooling control method provided by the embodiments of the present application is shown in Figure 1. As shown in the figure, the intelligent liquid cooling control method can include the following steps: Figure 1

[0033] Step S101, obtaining battery temperature data.

[0034] Among them, the temperature data of the battery can be collected by slave control, so as to determine the minimum battery temperature and the maximum battery temperature according to the temperature data of the battery.

[0035] Step S102, determining the temperature adjustment mode of the liquid cooling system based on the minimum battery temperature.

[0036] ​The temperature adjustment mode of the liquid cooling system can be determined by the relationship between the battery minimum temperature and the preset threshold, and the temperature adjustment mode can include a heating mode and a cooling mode.

[0037] The outlet water temperature of the water pump in the heating mode can be 25 DEG C, and the outlet water temperature of the water pump in the cooling mode can be 15 DEG C.

[0038] The liquid cooling system can include a PTC (Positive Temperature Coefficient) heater, a water pump, an electric compressor, a fan, a water-cooled relay, a main positive relay, and a plate heat exchanger, and the liquid cooling system can perform temperature control on the energy storage cabinet battery system, which can include at least one battery.

[0039] For the convenience of understanding, Figure 2 An interaction relationship diagram of elements in a liquid cooling system is provided for the embodiments of the application, and the specific interaction relationship of elements in the liquid cooling system is as shown in Figure 2 PACK-1, PACK-2, PACK-3, PACK-4, and PACK-5 represent five parallel batteries in the energy storage battery cabinet system.

[0040] The electric compressor can provide the required pressure for the system; the fan can be used for cooling or ventilation; the plate heat exchanger can transfer heat between different fluids; the water pump can provide water required for cooling or heating; the PTC heater generates heat when current passes through, and its resistance value increases with the increase of temperature, thereby limiting the current and preventing overheating, and can provide additional heat for the system; the water-cooled relay monitors and controls the system temperature, and when the system temperature exceeds the preset threshold, the corresponding cooling mechanism can be triggered by the water-cooled relay, such as starting the water pump or fan; the on-off of the control circuit is operated according to the control strategy or safety requirements of the system to cut off the power supply under certain conditions to protect the system.

[0041] The control strategy of some elements in the liquid cooling system is shown in Table 1 as follows:

[0042] Table 1:

[0043]

[0044] Wherein, △T represents the temperature difference, Tout represents the outlet water temperature of the water pump, and Ttarget represents the outlet water target temperature of the water pump, i.e. the standard temperature.

[0045] In step S103, the temperature control mode of the liquid cooling system is determined based on the temperature adjustment mode, the battery maximum temperature, and the battery minimum temperature.

[0046] The temperature control mode can include a pure heating mode, a charging and discharging heating mode and a self-circulation mode.

[0047] The temperature control mode can be determined according to the relationship between the battery maximum temperature adjusted by the temperature adjustment mode, the battery minimum temperature and a preset threshold.

[0048] The pure heating mode can be entered by closing a water cooling relay, and the charging and discharging heating mode can be entered by closing a main positive relay and the water cooling relay.

[0053] Embodiment 2

[0054] The embodiment of the application further provides another intelligent liquid cooling control method. Figure 3 Figure 3 As shown in the flowchart of another intelligent liquid cooling control method provided by the embodiment of the application,

[0055] In step S201, battery temperature data is obtained.

[0056] The temperature data of the battery can be collected by control, and the battery minimum temperature and the battery maximum temperature can be determined according to the temperature data of the battery.

[0057] In step S202, if the battery minimum temperature meets a preset first temperature threshold, the temperature adjustment mode is a heating mode.

[0058] The first temperature threshold can be 10℃, and the battery minimum temperature is considered to meet the first temperature threshold when the battery minimum temperature is less than 10℃.

[0059] In the heating mode, if the ambient temperature is in the interval [-30℃, 25℃) and the outlet water temperature of the water pump is less than the standard temperature, heating is maintained, the PTC heater and the water pump work; when the outlet water temperature of the water pump is greater than or equal to the standard temperature, self-circulation is started, at this time the PTC heater does not work and the water pump works.

[0060] In the heating mode, automatic heating below 10℃ can be realized to protect the battery.

[0061] In the heating mode, if the ambient temperature is in the interval [-30℃, 25℃) and the outlet water temperature of the water pump is less than the standard temperature, heating is maintained, the PTC heater and the water pump work; when the outlet water temperature of the water pump is greater than or equal to the standard temperature, self-circulation is started, at this time the PTC heater does not work and the water pump works.

[0062] In the heating mode, automatic heating below 10℃ can be realized to protect the battery.

[0063] In the cooling mode, if the ambient temperature is in the interval [0℃, 55℃] and the outlet water temperature of the water pump is greater than or equal to the standard temperature, cooling is maintained, the electric compressor, the fan and the water pump work; when the outlet water temperature of the water pump is less than the standard temperature, self-circulation is started, at this time the electric compressor and the fan do not work and the water pump works.

[0064] In the cooling mode, automatic cooling above 30℃ can be realized to protect the battery.

[0065] It should be noted that when the battery minimum temperature is greater than or equal to 10℃ and less than 30℃, the main positive relay can be directly closed for temperature adjustment to enable the battery to operate normally.

[0066] In the heating mode, if the ambient temperature is in the interval [-30℃, 25℃) and the outlet water temperature of the water pump is less than the standard temperature, heating is maintained, the PTC heater and the water pump work; when the outlet water temperature of the water pump is greater than or equal to the standard temperature, self-circulation is started, at this time the PTC heater does not work and the water pump works.

[0067] Specifically, determining the temperature control mode based on the battery minimum temperature can include: if the battery minimum temperature meets a third temperature threshold, the temperature control mode is a pure heating mode; if the battery minimum temperature meets a fourth temperature threshold, the temperature control mode is a charging and discharging heating mode.

[0068] The third temperature threshold can be 5℃, and it is considered that the battery minimum temperature meets the third temperature threshold when the battery minimum temperature is less than 5℃.

[0069] The fourth temperature threshold can be 5℃ and 10℃, and it is considered that the battery minimum temperature meets the fourth temperature threshold when the battery minimum temperature is greater than or equal to 5℃ and less than 10℃.

[0070] In the cooling mode, if the ambient temperature is in the interval [0℃, 55℃] and the outlet water temperature of the water pump is greater than or equal to the standard temperature, cooling is maintained, the electric compressor, the fan and the water pump work; when the outlet water temperature of the water pump is less than the standard temperature, self-circulation is started, at this time the electric compressor and the fan do not work and the water pump works.

[0071] Wherein, since the suitable working temperature of the battery is 25℃, the target outlet water temperature can be set to 10-25℃.

[0072] Specifically, determining the temperature control mode based on the battery maximum temperature, the outlet water temperature of the liquid cooling system and the outlet water target temperature of the liquid cooling system can include: if the battery maximum temperature meets the fifth temperature threshold, determining the temperature control mode as the self-circulation mode; or determining the temperature difference based on the outlet water temperature and the outlet water target temperature; determining the temperature control mode based on the temperature difference.

[0073] Wherein, the outlet water temperature and the target outlet water temperature maintain a relative temperature difference, which can ensure rapid adjustment of the battery temperature, but needs to ensure that the whole package is waterproof to prevent condensate.

[0074] Wherein, the fifth temperature threshold can be 28℃, and the battery maximum temperature less than 28℃ is considered to meet the fifth temperature threshold.

[0075] Wherein, determining the temperature control mode based on the temperature difference can include: if the temperature difference meets the sixth temperature threshold, determining the temperature control mode as the self-circulation mode; after the self-circulation mode lasts for a preset time, if the temperature difference does not meet the seventh temperature threshold, continuing the self-circulation mode; after the self-circulation mode lasts for a preset time, if the temperature difference meets the seventh temperature threshold, closing the refrigeration mode.

[0076] Wherein, the sixth temperature threshold can be 10℃, and the temperature difference greater than or equal to 10℃ is considered to meet the sixth temperature threshold.

[0077] Wherein, the seventh temperature threshold can be 6℃, and the temperature difference less than or equal to 6℃ is considered to meet the seventh temperature threshold.

[0078] Further, after the temperature control mode enters the charging and discharging heating mode, in order to ensure that the outlet water temperature and the target outlet water temperature maintain a relative temperature difference and achieve rapid cooling, the temperature control mode can be adjusted to the self-circulation mode when the battery minimum temperature is greater than or equal to 10℃, and lasts for 10 minutes; the heating mode is closed when the temperature difference is less than or equal to 6℃, the battery normally operates, if the temperature difference is greater than 6℃, the self-circulation mode is entered again for 10 minutes, until the temperature difference is less than or equal to 6℃.

[0079] For the convenience of understanding, Figure 4 A logic diagram of intelligent liquid cooling control provided by the embodiment of the application.

[0080] In practical application, the temperature data of the battery is collected to control and judge. When the lowest temperature of the battery is less than 10℃, the heating mode is started, and the outlet water temperature of the water pump is 25℃. After the heating mode is started, the lowest temperature of the battery is further judged. When the lowest temperature of the battery is less than 5℃, the water cooling relay is closed, and the pure heating mode is entered. After the adjustment of the pure heating mode, when the lowest temperature of the battery is greater than or equal to 5℃, the main positive relay and the water cooling relay are closed, and the charging and discharging heating mode is entered. After the adjustment of the charging and discharging heating mode, when the lowest temperature of the battery is greater than or equal to 10℃, the heating mode is closed, and the battery normally operates. When the lowest temperature of the battery is greater than or equal to 5℃ and less than 10℃, the main positive relay and the water cooling relay are directly closed, the charging and discharging heating mode is entered, and when the lowest temperature of the battery is greater than or equal to 10℃, the self-circulation mode is entered and lasts for 10 minutes. After 10 minutes, if the temperature difference is less than or equal to 6℃, the heating mode is closed, and the battery normally operates. After 10 minutes, if the temperature difference is greater than 6℃, the self-circulation mode lasts for another 10 minutes, and the heating mode is closed until the temperature difference is greater than 6℃.

[0081] When the lowest temperature of the battery is not less than 10℃ and greater than or equal to 30℃, the cooling mode is started, the outlet water temperature of the water pump is 15℃, the main positive relay and the water cooling relay are closed, and when the highest temperature of the battery is less than or equal to 28℃ or the temperature difference is greater than or equal to 10℃, the self-circulation mode is entered and lasts for 10 minutes. After 10 minutes, if the temperature difference is less than or equal to 6℃, the cooling mode is closed, and the battery normally operates. After 10 minutes, if the temperature difference is greater than 6℃, the self-circulation mode lasts for another 10 minutes, and the cooling mode is closed until the temperature difference is greater than 6℃.

[0082] When the lowest temperature of the battery is not less than 10℃ and less than 30℃, the main positive relay is directly closed, and the battery normally operates.

[0083] Further, if the number of battery packs is large, the battery packs can be processed in parallel under the premise that the flow, head, structure, etc. are sufficient, so as to avoid poor temperature control effect of the terminal battery and large temperature difference.

[0084] Wherein, the temperature difference is too large, which leads to poor consistency of the battery and reduces the service life of the battery. In the wooden barrel effect, the temperature of a single battery is too high, which also triggers a high temperature alarm. Therefore, the self-circulation mode time of 10 minutes is set.

[0085] Wherein, the temperature data of the battery is detected before the battery works. When the lowest temperature of the battery is lower than 5℃, only heating treatment is performed on the battery, and charging and discharging are not performed. In this way, the system can normally operate while being quickly heated. The problem that the market does not consider the low temperature condition or charges and discharges at the same time when heating at low temperature is prevented, and the service life of the battery is affected.

[0086] Wherein, the suitable temperature helps to accelerate the charging speed of the battery, and the battery can be charged by heating through the temperature range of 5℃≤battery minimum temperature<10℃. In order to charge in a low temperature environment without damaging the battery, when the battery minimum temperature is less than 5℃, only the pure heating mode is supported, the request current is the heating current, and after the battery temperature rises to the set temperature, the battery can enter other processes to protect the battery from being affected by large current charging.

[0087] The intelligent liquid cooling control method provided by the embodiment of the application can determine the temperature adjustment mode and the temperature control mode by setting different temperature thresholds, thereby controlling the battery temperature, and effectively prolonging the service life of the battery.
