Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling, in particular to a liquid cooling control system and a liquid cooling system. Background Art

[0002] An energy storage system is a device that can store excess energy and release it when needed. In the field of new energy, energy storage systems are widely used in the storage and utilization of energy such as solar energy and wind energy. The main working unit of energy storage is the battery pack, and temperature has a great impact on the charging and discharging function of the battery pack. Excessive temperature will destroy the chemical balance inside the battery pack and cause side reactions. In a low temperature environment, the electrochemical reaction rate of lithium batteries slows down, resulting in a decrease in battery capacity and power output. A liquid cooling system is required to control the temperature of the battery pack through coolant.

[0003] The existing liquid cooling system will be affected when the external power supply is unstable or power outages. For example, an external power outage will cause the liquid cooling system to stop working, which in turn will cause the battery pack to fail to work within the set temperature range, and in severe cases will cause damage to the battery pack.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here.

[0049] Figure 1 Schematic diagram of a liquid cooling control system provided according to an embodiment of the utility model. Figure 1 As shown, the liquid cooling control system includes: a power input terminal 11, a main control module 12, a voltage conversion module 13 and a temperature control module 14; the power input terminal 11 is connected to a first input terminal of the temperature control module 14 and an input terminal of the voltage conversion module 13; a second input terminal of the temperature control module 14 is connected to a first output terminal of the voltage conversion module 13, a second output terminal of the voltage conversion module 13 is connected to a power input terminal of the main control module 12, and a control output terminal of the main control module 12 is connected to the temperature control module 14; the power input terminal 11 is used to provide high-voltage direct current; the voltage conversion module 13 is used to convert high-voltage direct current into a preset voltage; the main control module 12 is used to control the working state of the temperature control module 14; the temperature control module 14 is used to adjust the temperature of the device to be adjusted.

[0050] In the embodiment of the utility model, the power input terminal 11 is a port for supplying power to the liquid cooling system, and is used to provide high-voltage direct current. For example, the 220V or 380V AC power supply used in the related art is easily restricted by environmental conditions such as the power grid, while the power input terminal 11 in the embodiment of the utility model can use a 900V high-voltage battery pack to provide a stable and safe 900V high-voltage power supply to the liquid cooling system. When the liquid cooling system is working, the high-voltage power supply is directly provided to the liquid cooling system through the 900V high-voltage battery pack to ensure the stable operation of the liquid cooling system.

[0051] The temperature-adjustable device may be a battery pack in an energy storage system. Since the battery pack is greatly affected by temperature, it is crucial to adjust the ambient temperature of the battery pack. A temperature control module 14 is provided in the liquid cooling control system, and the power input terminal 11 is connected to the first input terminal of the temperature control module 14 to provide a stable power supply for the temperature control module 14. The temperature control module 14 includes a heating device and a cooling device. The heating device includes but is not limited to an electric heater; the cooling device includes but is not limited to a fan or a compressor. According to the temperature of the battery pack, the heating device is controlled to start or the cooling device is controlled to start. Exemplarily, when the temperature of the battery pack is too low, the heating device in the temperature control module 14 is started, and the power input terminal 11 provides 900V high-voltage direct current, which is directly transmitted to the electric heater, and the electric heater works to increase the temperature of the battery pack. It should be noted that since the electric heater is directly connected to the power input terminal 11, when the power input terminal 11 provides 900V high-voltage direct current, the voltage is relatively high, and safety issues need special attention. Therefore, an electric heater with high-voltage resistance needs to be selected. Exemplarily, an electric heater with 1000V high-voltage resistance is selected.

[0052] The preset voltage includes two voltage values, one of which is the rated voltage that meets the working conditions of the refrigeration device in the temperature control module 14; the other is the rated voltage that meets the working conditions of the main control module 12. Exemplarily, the working voltage of the fan or water pump is 24V. The voltage conversion module 13 is used to convert high-voltage direct current into a preset voltage. Exemplarily, 900V high-voltage direct current is converted into 24V. The voltage conversion module 13 can use a DC / DC converter. Since the DC voltage provided by the power input terminal 11 is between 600V and 900V, the current energy storage products do not meet the high voltage working specifications, so the voltage is converted by the voltage conversion module 13 to power devices such as fans.

[0053] The main control module 12 may be a thermal management controller (Hot Controller Management, HCM). Exemplarily, the operating voltage of the HCM may be 24V, so the main control module 12 is connected to the power input terminal 11 through the voltage conversion module 13, and the voltage conversion module 13 converts the high-voltage direct current provided by the power input terminal 11 into 24V, and transmits it to the main control module 12 for the main control module 12 to work. The main control module 12 is connected to the battery management system (Battery Management System, BMS) through a serial communication protocol (Controller Area Network, CAN) bus. The main control module 12 is also connected to the temperature control module 14. The main control module 12 is used to control the working state of the temperature control module 14. Exemplarily, when the main control module 12 receives a cooling communication instruction, the main control module 12 controls the cooling device of the temperature control module 14 to start and reduce the temperature of the battery pack.

[0054] The working principle of the liquid cooling control system is that the power input terminal 11 provides high-voltage direct current for the system. Since the operating voltage of some electrical components in the system is relatively low, the voltage conversion module 13 is used to convert the high-voltage direct current into a low voltage suitable for the operation of the electrical components; the main control module 12 is connected to the temperature control module 14. When receiving a communication instruction to control the temperature change, the main control module 12 controls the working state of the temperature control module 14 to achieve temperature regulation of the temperature-adjustable device.

[0055] The technical solution of the embodiment of the utility model is to provide a high-voltage DC power supply by setting a power input terminal, and the voltage conversion module converts the high-voltage DC power into a preset voltage, so that the liquid cooling control system can work according to the high-voltage DC power supply. The high-voltage DC power supply has stable and safe performance, ensuring the stable operation of the liquid cooling system; when the main control module controls the working state of the temperature control module, the temperature of the battery pack is adjusted to achieve the battery pack working at the set temperature, thereby extending the life of the battery pack.

[0057] In an embodiment of the utility model, the first preset voltage is a voltage value pre-set to enable the main control module 12 to work normally. Exemplarily, the first preset voltage is 24V. The first DC / DC converter 131 can use a 75wDC / DC converter. The first DC / DC converter 131 is connected between the power input terminal 11 and the main control module 12. The main control module 12 uses a thermal management controller (HCM). The operating voltage of the HCM is 24V. The first DC / DC converter 131 converts the 900V high voltage output from the power input terminal 11 into 24V and outputs it to the HCM to enable the HCM to work normally. The first DC / DC converter 131 is connected to the A34 pin of the HCM. The battery management system 30 is connected to the A8 and A9 pins of the HCM via CAN bus communication.

The first refrigeration unit 141 is directly connected to the power input terminal 11 without passing through the voltage conversion module 13, so the first refrigeration unit 141 needs to use a high-voltage resistant device. For example, the first refrigeration unit 141 uses a compressor driver that can withstand a high voltage of 1000V. The main control module 12 controls the start-up of the compressor to cool down the temperature-adjustable device.

[0061] In the embodiment of the utility model, the second preset voltage is a voltage value preset to enable the second refrigeration unit 142 to work normally. Exemplarily, the second preset voltage is 24V. The second DC / DC converter 132 can use a 1500wDC / DC converter. The second DC / DC converter 132 is connected between the power input terminal 11 and the second refrigeration unit 142. The second refrigeration unit 142 can use a fan, and the working voltage of the fan is 24V. The second DC / DC converter 132 converts the 900V high voltage output from the power input terminal 11 into 24V, and outputs it to the fan, so that the fan works normally.

[0062] The preset pressure is a preset minimum pressure for starting the second refrigeration unit 142. For example, the preset pressure is 1000 KPa. When the pressure generated by the first refrigeration unit 141 is greater than or equal to 1000 KPa, such as when the pressure generated by the first refrigeration unit 141 is 1200 KPa, the second refrigeration unit 142 is started to continue cooling the temperature-adjustable device.

[0063] Based on the above utility model embodiment technical solution, reference Figure 2 As shown, the first refrigeration unit 141 includes a compressor driver 1411 and a compressor 1412; the compressor driver 1411 is connected to the power input terminal 11; the compressor 1412 is connected to the compressor driver 1411; the compressor driver 1411 is used to drive the compressor 1412 to work.

[0064] In the embodiment of the utility model, the compressor driver 1411 is connected to the power input terminal 11, and the compressor 1412 is connected to the compressor driver 1411. The compressor driver 1411 provides enough starting current and torque for the compressor 1412, so that the compressor 1412 can start smoothly. The compressor 1412 can be powered by a 380V AC power supply. The compressor driver 1411 is also connected to a high-pressure pressure switch 1413, and the high-pressure pressure switch 1413 is used to implement overvoltage protection for the compressor driver 1411 and the compressor 1412. The compressor driver 1411 is connected to the A4 and A5 pins of the HCM.

The operating voltages of the first fan 1421, the second fan 1422 and the water pump 1423 are all 24V, and need to be connected to the power input terminal 11 through the second DC / DC converter 132. When the first refrigeration unit 141 is in working state, the water pump 1423 is also in working state. When the liquid cooling system is in self-circulation, heating or cooling state, the water pump 1423 is in working state.
