Description

Technical Field

[0001] The present invention relates to the field of battery swap station control, and in particular to a battery compartment ventilation system and a temperature control method, device, and medium. Background Art

[0002] Due to restrictions on charging time and location, many new energy electric vehicles are now gradually adopting a quick-swap method (i.e., a mode of quickly replacing batteries) for energy replenishment. Depleted batteries removed from electric vehicles need to be charged at a battery swap station or energy storage station. These stations are equipped with a battery compartment with multiple battery racks for storing battery packs to be charged. To ensure the safety of the battery packs, certain temperature requirements are imposed on the compartment. In existing technology, this temperature regulation is generally regulated by air conditioning equipment. This temperature regulation method consumes a lot of electricity and costs a lot of money. Furthermore, due to the large size of the battery swap compartment, it is necessary to take into account the temperature control of the battery positions in each area, which requires a lot of air conditioning equipment, resulting in high investment costs.

[0003] The patent application with publication number CN211731084U discloses a heat exchange system for a battery swap station, which specifically discloses that: the ventilation channel of the heat exchange system is connected to the heat dissipation device of the charger. When it is identified that the charging compartment needs to dissipate heat, the air flowing through the ventilation channel is controlled to be discharged to the outside of the battery swap station through the first air outlet to dissipate heat for the charging compartment. When it is identified that the charging compartment needs to be heated, the air flowing through the ventilation channel is controlled to be discharged into the charging compartment through the second air outlet to heat the charging compartment. Its essence is to discharge the heat of the charger to the outside when the battery compartment temperature is too high or heat dissipation is required, and retain the heat of the charger when the battery compartment temperature is not high or heating is required. However, there is a problem. In the case where the heat of the charger needs to be discharged, the heat is not effectively utilized, and only a channel is provided to discharge the heat directly to the outside.

[0004] Patent application publication number CN206461399U discloses a charger, specifically disclosing: A sealed ventilation duct, a control circuit board, a heat-conducting device, and a fan are located within the charger housing. The heat-conducting device is partially located within the sealed ventilation duct, and the fan uses the duct to dissipate heat conducted by the heat-conducting device. The control circuit is attached to the inner wall of the housing to conduct heat to the housing, thereby improving heat dissipation. Essentially, the fan dissipates heat conducted by the heat-conducting device through the sealed ventilation duct. This heat is still not effectively utilized, but merely provides a channel for dissipation to the outside. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art in which the heat generated by the charger during the charging process is not reasonably and effectively utilized, and the temperature regulation of the battery compartment by using air-conditioning equipment, etc. is performed with low efficiency and high cost, and a battery compartment ventilation system and temperature control method, equipment and medium are provided.

[0059] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0060] Example 1

[0061] A battery compartment ventilation system is used in a battery swap station or an energy storage station. The battery swap station or the energy storage station includes a battery compartment 1 for storing battery packs and a charging compartment 2 for placing a charger. Figure 1-2 As shown, the ventilation system of the battery compartment 1 includes an air inlet and an air outlet arranged on the charging compartment 2 and a ventilation unit connecting the battery compartment 1 and the charging compartment 2. The air inlet and the air outlet can be opened and closed, and the ventilation unit can be opened and closed and the flow direction can be adjusted.

[0062] It should be noted that there is a partition between the battery compartment and the charging compartment to separate the two areas. The air circulation between the battery compartment and the charging compartment can be achieved through the ventilation unit. During the process of the battery compartment charging the battery pack, severe heat will occur. If it is detected that the temperature of the charging compartment is too low, the hot air in the charging compartment can be guided into the battery compartment through the air circulation channel between the battery compartment and the charging compartment to adjust the temperature inside the battery compartment.

[0063] In one possible implementation, see Figure 2 A charging rack 21 is provided in the charging compartment 2 along the vertical direction, and a plurality of charging positions 22 are provided on the charging rack 21 along the vertical direction. A charger 23 is provided in each charging position 22 in a one-to-one correspondence. The air outlet is located in the top area of ​​the charging compartment 2, and the air inlet is set in the bottom area of ​​the charging compartment 2 to fully cover the charger 23 in the charging rack 21 from bottom to top.

[0064] In the above embodiment, it is preferred to set the air inlet at the bottom of the charging compartment and the air outlet at the top of the charging compartment, so as to cover all vertically arranged chargers, and realize the temperature regulation efficiency of the air circulation between the air inlet and the air outlet of the charger itself; and, the heat generated by all the chargers can be fully utilized to regulate the temperature of the battery compartment, saving energy.

[0065] When two rows of charging racks 21 are arranged opposite to each other in the charging compartment 2, see Figure 3 A plurality of chargers 23 are arranged relative to each other in the charging positions 22 of the two rows of charging racks 21 so that an air inlet area for each charger is formed between the two rows of charging racks 21, and the air inlet is arranged at a lower position of the charging compartment 2 corresponding to the air inlet area.

[0066] In the above embodiment, when two rows of charging racks are provided in the charging compartment, in order to ensure that the heat generated by all chargers can be fully utilized, it is preferred to set the air inlet at a lower position corresponding to the air inlet area formed between the two rows of charging racks, so that the air can enter from between the two rows of chargers, cover all chargers, and improve the circulation efficiency. The air outlet is still provided at the top of the charging compartment.

[0067] In this embodiment, the position of the ventilation unit can be set differently according to needs, for example:

[0068] The ventilation unit includes a vent located near the top of the battery compartment 1. The vent allows for overall air circulation between the battery compartment 1 and the charging compartment 2, and the overall temperature of the battery compartment 1 can be adjusted accordingly.

[0069] Or, as Figure 2 As shown in Figure 3, a battery rack 11 is vertically disposed within the battery compartment 1. A plurality of battery positions 12 are vertically disposed on the battery rack 11. The battery positions 12 correspond one-to-one with the charging positions 22. The ventilation unit includes a plurality of vents corresponding to the battery positions 12 connected to each charging position 22. Specifically, the plurality of vents are disposed at positions corresponding to the battery positions 12 connected to each charging position 22. Based on this, direct communication with one or more battery positions 12 can be further achieved, thereby enabling targeted temperature adjustment of the one or more battery positions 12.

[0070] In one practicable embodiment, the ventilation system further includes a ventilation duct that is interconnected between the air inlet, the air outlet, and the ventilation unit, or the three of them, and is formed through the main structure of the charging compartment and / or the battery compartment.

[0071] In the above embodiment, ventilation ducts are formed based on the main body structure of the charging compartment and / or battery compartment, connecting the air inlet, air outlet, and ventilation units in pairs or in pairs, so as to guide the air flow path, reduce the additional pipeline layout, and reduce costs.

[0072] In this embodiment, in order to rationally utilize the heat generated by the charger in the charging compartment during the charging of the battery pack in the battery compartment, a ventilation system is specially arranged between the battery compartment and the charging compartment to realize air circulation between the battery compartment and the charging compartment, thereby realizing the temperature adjustment of the battery compartment, reducing the power consumption of equipment such as air conditioners in the battery compartment, and effectively utilizing the heat of charging at the same time, reducing the charging efficiency drop of the charger in the charging compartment or equipment damage caused by high temperature.

[0073] Example 2

[0074] A battery compartment temperature control method, the battery compartment temperature control method is implemented based on the battery compartment ventilation system as in Example 1, as Figure 4 As shown, the following steps are included:

[0075] Step 10: Obtain the internal temperature of the battery compartment and the charging compartment respectively;

[0076] Among them, temperature data is detected and obtained by setting temperature sensors at one or more locations in the battery compartment and the charging compartment.

[0077] Step 20: Control the opening and closing of the air inlet, air outlet, and ventilation unit, as well as the air flow path, according to the temperature inside the battery compartment and the charging compartment.

[0078] When adjusting the battery compartment temperature, if the temperature inside the battery compartment is low, the hot air from the charging compartment can be controlled to flow into the battery compartment to replenish the temperature inside the battery compartment. Specifically, the opening and closing of the ventilation unit, including the size of the opening, can be further adjusted based on the temperature difference between the battery compartment and the charging compartment. If the battery compartment temperature is too high, the hot air can be discharged out of the compartment through the ventilation unit of the charging compartment and the air outlet of the charging compartment to reduce the temperature inside the compartment. Specifically, the opening and closing of the ventilation unit, including the size of the opening, can be further adjusted based on the temperature of the battery compartment.

[0079] In one practicable manner, step 20 specifically includes:

[0080] When the temperature inside the battery compartment is lower than the temperature inside the charging compartment and the temperature inside the battery compartment is lower than a preset first temperature threshold, an air flow path is formed between the control air inlet and the ventilation unit to obtain hot air in the charging compartment to regulate the temperature of the battery compartment.

[0081] Among them, when the temperature inside the battery compartment is lower than the temperature inside the charging compartment, and the temperature inside the battery compartment is lower than the preset temperature value, the air inlet and ventilation unit of the charging compartment are controlled to open to achieve air convection between the two. External air enters through the air inlet of the charging compartment, so that the hot air in the charging compartment flows into the battery compartment to achieve thermal supplementation of the temperature inside the battery compartment.

[0082] In one feasible manner, the air conditioning equipment in the battery compartment can be used to adjust the temperature of the battery compartment at the same time, thereby further accelerating the rate at which the temperature of the battery compartment rises.

[0083] In one practicable manner, step 20 further includes:

[0084] When the temperature inside the battery compartment is lower than a preset second temperature threshold, closing the air outlet;

[0085] The second temperature threshold is lower than the first temperature threshold.

[0086] Among them, when the temperature inside the battery compartment is lower than the temperature inside the charging compartment, and the temperature inside the battery compartment is lower than the preset second temperature threshold, the air outlet of the charging compartment is closed, and the air inlet and ventilation unit of the charging compartment are controlled to open to achieve air convection between the two. External air enters through the air inlet of the charging compartment, so that all the hot air in the charging compartment flows into the battery compartment, so as to achieve sufficient heat supplementation of the temperature inside the battery compartment.

[0087] In one practicable manner, step 20 further includes:

[0088] When the temperature inside the charging compartment is lower than a preset third temperature threshold, the ventilation unit is turned off.

[0089] Among them, in the process of hot air flowing from the charging compartment into the battery compartment to realize thermal supplement of the temperature in the battery compartment, if it is detected that the temperature of the charging compartment is lower than the preset third temperature threshold, the ventilation unit is closed, that is, the thermal supplement of the temperature in the battery compartment is stopped. At this time, if the temperature of the battery compartment needs to be further adjusted, the air-conditioning equipment in the battery compartment can be used to adjust the temperature of the battery compartment to further increase the temperature of the battery compartment.

[0090] In one practicable manner, step 20 further includes:

[0091] When the temperature inside the battery compartment is greater than a preset fourth temperature threshold, an air flow path is formed between the ventilation unit and the air outlet, wherein the first temperature threshold is less than the fourth temperature threshold.

[0092] Among them, when the temperature inside the battery compartment is higher than the preset temperature value, the air outlet and ventilation unit of the charging compartment are controlled to open to achieve air convection between the two. The hot air in the battery compartment is discharged out of the compartment through the ventilation unit and the air outlet of the charging compartment to achieve cooling of the temperature inside the battery compartment.

[0093] In one feasible method, an exhaust fan can be installed at the air outlet of the charging compartment. By turning on the exhaust fan to extract the hot air from the battery compartment, the rate of temperature reduction of the battery compartment can be accelerated. Alternatively, the air conditioning equipment in the battery compartment can be used to adjust the temperature of the battery compartment at the same time to further accelerate the rate of temperature reduction of the battery compartment.

[0094] In one feasible manner, air inlets and outlets may be provided in the battery compartment to achieve air circulation between the inside and outside of the battery compartment, thereby achieving temperature regulation in the battery compartment.

[0095] In this embodiment, the heat generated during the charging process of the battery pack in the battery compartment by the charger in the charging compartment is reasonably utilized. A ventilation system is specially set between the battery compartment and the charging compartment to achieve air circulation between the battery compartment and the charging compartment. When the temperature of the battery compartment is lower than the temperature of the charging compartment, the temperature of the battery compartment is regulated by the air circulation between the two, thereby reducing the power consumption of equipment such as the air conditioner in the battery compartment. At the same time, the heat of charging is effectively utilized to reduce the charging efficiency drop of the charger in the charging compartment or equipment damage caused by high temperature. When the temperature of the battery compartment is higher than the temperature of the charging compartment, the air outlet of the charging compartment is used to discharge the hot air from the battery compartment.

[0096] Example 3

[0097] A battery swap station or energy storage station, such as Figure 5 As shown, the battery swap station or energy storage station includes a temperature detection module 3, a control module 4 and the above-mentioned battery compartment ventilation system;

[0098] The temperature detection module 3 is used to obtain the temperature inside the battery compartment and the charging compartment respectively;

[0099] Among them, temperature data is detected and obtained by setting temperature sensors at one or more locations in the battery compartment and the charging compartment.

[0100] The control module 4 is used to control the opening and closing of the air inlet, air outlet and ventilation unit according to the temperature inside the battery compartment and the charging compartment, including the opening size and air flow path;

[0101] The battery swap station or energy storage station has an upper box body and a lower box body, the air inlet is arranged in the bottom area of ​​the lower box body, and the air outlet is arranged in the top area of ​​the upper box body.

[0102] When adjusting the battery compartment temperature, if the temperature inside the battery compartment is low, the hot air from the charging compartment can be controlled to flow into the battery compartment to replenish the temperature inside the battery compartment. Specifically, the opening and closing of the ventilation unit, including the size of the opening, can be further adjusted based on the temperature difference between the battery compartment and the charging compartment. If the battery compartment temperature is too high, the hot air can be discharged out of the compartment through the ventilation unit of the charging compartment and the air outlet of the charging compartment to reduce the temperature inside the compartment. Specifically, the opening and closing of the ventilation unit, including the size of the opening, can be further adjusted based on the temperature of the battery compartment.

[0103] In one feasible embodiment, when the temperature inside the battery compartment is lower than the temperature inside the charging compartment and the temperature inside the battery compartment is lower than a preset first temperature threshold, the control module 4 is used to control the formation of an air flow path between the air inlet and the ventilation unit to obtain hot air in the charging compartment to regulate the temperature of the battery compartment.

[0104] Among them, when the temperature inside the battery compartment is lower than the temperature inside the charging compartment, and the temperature inside the battery compartment is lower than the preset temperature value, the air inlet and ventilation unit of the charging compartment are controlled to open to achieve air convection between the two. External air enters through the air inlet of the charging compartment, so that the hot air in the charging compartment flows into the battery compartment to achieve thermal supplementation of the temperature inside the battery compartment.

[0105] In one feasible manner, the air conditioning equipment in the battery compartment can be used to adjust the temperature of the battery compartment at the same time, thereby further accelerating the rate at which the temperature of the battery compartment rises.

[0106] In one practicable manner, when the temperature inside the battery compartment is lower than a preset second temperature threshold, the control module 4 is configured to close the air outlet;

[0107] The second temperature threshold is lower than the first temperature threshold.

[0108] Among them, when the temperature inside the battery compartment is lower than the temperature inside the charging compartment, and the temperature inside the battery compartment is lower than the preset second temperature threshold, the air outlet of the charging compartment is closed, and the air inlet and ventilation unit of the charging compartment are controlled to open to achieve air convection between the two. External air enters through the air inlet of the charging compartment, so that all the hot air in the charging compartment flows into the battery compartment, so as to achieve sufficient heat supplementation of the temperature inside the battery compartment.

[0109] In one practicable manner, when the temperature inside the charging compartment is lower than a preset third temperature threshold, the control module 4 is configured to turn off the ventilation unit.

[0110] Among them, in the process of hot air flowing from the charging compartment into the battery compartment to realize thermal supplement of the temperature in the battery compartment, if it is detected that the temperature of the charging compartment is lower than the preset third temperature threshold, the ventilation unit is closed, that is, the thermal supplement of the temperature in the battery compartment is stopped. At this time, if the temperature of the battery compartment needs to be further adjusted, the air-conditioning equipment in the battery compartment can be used to adjust the temperature of the battery compartment to further increase the temperature of the battery compartment.

[0111] In one practicable manner, when the temperature inside the battery compartment is greater than a preset fourth temperature threshold, the control module 4 is configured to control the formation of an air flow path between the ventilation unit and the air outlet.

[0112] Among them, when the temperature inside the battery compartment is higher than the preset temperature value, the air outlet and ventilation unit of the charging compartment are controlled to open to achieve air convection between the two. The hot air in the battery compartment is discharged out of the compartment through the ventilation unit and the air outlet of the charging compartment to achieve cooling of the temperature inside the battery compartment.

[0113] In one feasible method, an exhaust fan can be installed at the air outlet of the charging compartment. By turning on the exhaust fan to extract the hot air from the battery compartment, the rate of temperature reduction of the battery compartment can be accelerated. Alternatively, the air conditioning equipment in the battery compartment can be used to adjust the temperature of the battery compartment at the same time to further accelerate the rate of temperature reduction of the battery compartment.

[0114] In one feasible manner, air inlets and outlets may be provided in the battery compartment to achieve air circulation between the inside and outside of the battery compartment, thereby achieving temperature regulation in the battery compartment.

[0115] In this embodiment, the heat generated during the charging process of the battery pack in the battery compartment by the charger in the charging compartment is reasonably utilized. A ventilation system is specially set between the battery compartment and the charging compartment to achieve air circulation between the battery compartment and the charging compartment. When the temperature of the battery compartment is lower than the temperature of the charging compartment, the temperature of the battery compartment is regulated by the air circulation between the two, thereby reducing the power consumption of equipment such as the air conditioner in the battery compartment. At the same time, the heat of charging is effectively utilized to reduce the charging efficiency drop of the charger in the charging compartment or equipment damage caused by high temperature. When the temperature of the battery compartment is higher than the temperature of the charging compartment, the air outlet of the charging compartment is used to discharge the hot air from the battery compartment.
