Description

Technical Field

[0001] This utility model relates to the field of thermal management technology for energy storage batteries, and specifically to an energy storage-charging system with integrated heat pump thermal management. Background Technology

[0002] With the accelerated pace of the global energy transition, the energy storage battery and electric vehicle charging pile industries are experiencing explosive growth. Integrated Energy Storage and Charging Systems (IESCS) are becoming a key development direction for future smart energy systems. However, in the wave of "zero-carbon park" construction, existing technologies still face multiple challenges for industrial parks equipped with commercial heat pumps, industrial and commercial liquid-cooled energy storage battery systems, and liquid-cooled DC charging piles:

[0003] On the one hand, the system integration is insufficient. In the current system architecture, energy storage batteries and charging piles usually require independent cooling equipment, which increases system complexity and cost, while reducing overall energy efficiency.

[0004] On the other hand, there is a lack of coordinated energy management. Existing systems lack intelligent scheduling algorithms; batteries and charging stations typically operate independently, with a matching rate of less than 60% between battery charging / discharging and charging station operation. The lack of coordinated energy flow management between the two leads to energy waste and low utilization. Waste heat recovery rates are also low; energy storage batteries and charging stations typically employ independent liquid-cooling circulation systems, resulting in dispersed waste heat that is difficult to centrally recover. The cooling systems of heat pumps, energy storage batteries, and charging stations lack thermal coupling design, and waste heat is not effectively integrated and utilized.

[0005] Therefore, there is an urgent need for an energy storage-charging system that has no additional structure, can efficiently manage the liquid cooling thermal of the energy storage battery and DC charging pile, and realizes the recovery and utilization of the charging pile's energy.

[0041] In one embodiment of this utility model, the energy storage module 5 includes a third heat exchanger 501, a second water pump 502, and a second three-way valve 503 connected in series. The third heat exchanger 501 is connected to the second heat exchanger 401.

[0044] As an embodiment of this utility model, the first water pump 402 and the second water pump 502 are both circulating water pumps. The circulating water pumps are used to force the circulation of coolant, so as to evenly dissipate the heat generated by the energy storage module 5 and the charging module 4, avoid local overheating, and make the heat exchange uniform.

[0045] The integrated heat pump thermal management energy storage-charging system includes a high-temperature heat dissipation mode, a low-temperature heating mode, and a waste heat recovery mode.

[0046] The working principle of the energy storage-charging system with integrated heat pump thermal management is as follows:

[0047] High-temperature heat dissipation modes such as Figure 3 As shown: When the temperature monitoring module detects that the battery cells in the energy storage module 5 or the power electronic devices in the charging module 4 have reached a preset high temperature threshold, the heat pump module 3 starts the cooling mode, and the A1-B1 terminals of the first three-way valve 303 are connected. At this time, the heat pump module 3 and the cold water tank 1 are connected in series to form a coolant cooling circuit. When the first heat exchanger 301 lowers the temperature of the coolant in the cold water tank 1 to the preset temperature, the first heat exchanger 301 stops cooling and closes the return water pump 302 and the first three-way valve 303. Subsequently, the first shut-off valve 101 opens, and at the same time, the A2-B2 terminals of the second shut-off valve 403 and / or the second three-way valve 503 are connected. At this time, the low-temperature coolant in the cold water tank 1 can be pumped out by the first water pump 402 and / or the second water pump 502 to cool down the battery cells in the energy storage module 5 or the high-temperature power electronic devices in the charging module 4, until the battery cells in the energy storage module 5 or the power electronic devices in the charging module 4 reach the preset high temperature and low threshold, then the corresponding cycle stops.

[0048] Low-temperature heating mode such as Figure 4 As shown: When the temperature monitoring module detects that the cell temperature in the energy storage module 5 reaches the preset low temperature threshold, the heat pump module 3 starts the heating mode, and the B1-C1 terminals of the first three-way valve 303 are connected. At this time, the heat pump module 3 and the hot water tank 2 are connected in series to form a coolant heating circuit. When the first heat exchanger 301 raises the coolant temperature in the hot water tank 2 to the preset temperature, the first heat exchanger 301 stops heating and closes the return water pump 302 and the first three-way valve 303. Subsequently, the first shut-off valve 101 and the second shut-off valve 403 are closed, and the A2-C2 terminals of the second three-way valve 503 are connected. The second water pump 502 pumps out high-temperature coolant to heat the cells in the energy storage module 5 until the cells in the energy storage module 5 reach the preset low temperature threshold, at which point the coolant circulation stops.

[0049] Waste heat recovery mode such as Figure 5As shown: When the temperature monitoring module detects that the cell temperature in the energy storage module 5 is between a preset low-temperature low threshold and a preset low-temperature high threshold, if the charging module 4 is operating at this time, the second shut-off valve 403 is opened, the first shut-off valve 101 is closed, the A2-B2 terminals of the second three-way valve 503 are connected, the second water pump 502 is turned on, and the high-temperature coolant in the second heat exchanger 401 is pumped into the third heat exchanger 501, thereby increasing the cell temperature of the energy storage module 5 and, to a certain extent, reducing the temperature of the power electronic devices in the charging module 4. Further, if the battery temperature of the energy storage module 5 reaches the preset low-temperature high threshold or the power electronic devices in the charging module 4 reach the preset high-temperature high threshold, the waste heat recovery mode is exited, and the coolant circulation between the energy storage module 5 and the charging module 4 is stopped.

[0050] The integrated heat pump thermal management energy storage-charging system provided by this utility model integrates the heat pump module 3, cold water tank 1, and hot water tank 2 on the basis of existing energy storage-charging systems. Through integrated design, the cooling requirements of the charging module 4 and the heat dissipation requirements of the energy storage module 5 are integrated, eliminating the need for a separate liquid cooling unit. By sharing the circulation loop of the heat pump module 3, redundant equipment is reduced, significantly lowering equipment costs and floor space. At the same time, the waste heat generated by the charging module 4 is recovered and utilized, further improving energy utilization while ensuring stable equipment operation. It is suitable for various new energy infrastructures, especially for scenarios with strict requirements on space, cost, and energy efficiency.

[0051] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
