The vehicle may be a variety of quick-change electric or hybrid vehicles such as an SUV, a car, an off-road vehicle, a truck, a bus, and the like.
Of course, the power swapping station 100 may be of other types and forms.
As shown in fig. 3, the charging rack 160 includes a plurality of charging bins 161, the charging bins 161 are used for placing battery packs 300, and charging modules 162 are disposed in the charging bins 161, so that the battery packs 300 to be charged are charged through the charging modules 162.

In the present embodiment, the step of temperature-regulating the battery pack 300 includes heat exchange with the outer surface of the battery pack 300 to achieve temperature regulation. The temperature of the surface of the battery pack 300 is exchanged to lower or raise the temperature of the battery pack 300 when the temperature of the battery pack 300 is excessively high or low by exchanging heat with the outer surface of the battery pack 300. Wherein, the heat exchange is performed through the heat exchange assembly 264, the heat exchange assembly 264 is arranged in the vicinity area outside the battery pack 300, and the temperature adjusting system 200 realizes the heat exchange by controlling the heat exchange assembly 264 to contact with the outer surface of the battery pack 300, thereby adjusting the temperature of the battery pack 300.
In the present embodiment, collecting the temperature of the battery pack 300 includes collecting the temperature of a plurality of regions of the battery pack 300. By collecting the temperatures of a plurality of areas of the battery pack 300, the temperature of the battery pack 300 can be more accurate, the problem that the service life of the battery pack 300 is affected due to the fact that the temperature data obtained by collecting only a single area of the battery pack 300 is inaccurate is avoided, and the overall temperature of the battery pack 300 is always within the proper working temperature range.
In this embodiment, one heat exchange assembly 264 is correspondingly arranged in different areas outside the battery pack 300, and after the temperatures of the plurality of areas of the battery pack 300 are collected, the heat exchange assembly 264 corresponding to the areas is controlled by the temperature adjustment system 200 to perform heat exchange according to the collected temperatures of the different areas of the battery pack 300. By adjusting the temperature of each region of the battery pack 300, the temperature of each region of the battery pack 300 can be kept consistent, and the local temperature of the battery pack 300 is prevented from not falling or rising to a proper normal working temperature range.
In this embodiment, the step of collecting the temperature of the battery pack 300 is:
s11, collecting the temperatures of a plurality of side surfaces of the battery pack 300;
and S12, obtaining the temperature of the battery pack 300 according to the temperatures of the plurality of side surfaces.
In step S11, the process of acquiring the temperature of any one side surface of the battery pack 300 includes: a plurality of collecting points are arranged on one side face of the battery pack 300, and the highest temperature value in the plurality of collecting points is selected as the temperature of the side face, so that the problem that the temperature value obtained under the condition that only one collecting point is arranged is inaccurate, and the temperature adjusting effect of the battery pack 300 is further influenced can be avoided.
In this embodiment, the method for controlling the temperature adjustment system 200 to adjust the temperature of the battery pack 300 includes: a first temperature threshold value and a second temperature threshold value are preset in the temperature adjusting system 200, and the first temperature threshold value is smaller than the second temperature threshold value; when the collected temperature of the battery pack 300 is between the first temperature threshold and the second temperature threshold, controlling the temperature adjusting system 200 to output a normal-temperature fluid to perform constant-temperature adjustment on the battery pack 300; when the collected temperature of the battery pack 300 is greater than a second temperature threshold value, controlling the temperature adjusting system 200 to output cooled fluid to adjust the temperature of the battery pack 300; and when the collected temperature of the battery pack 300 is smaller than the first temperature threshold value, controlling the temperature adjusting system 200 to output the heated fluid to perform temperature rise adjustment on the battery pack 300.
Fig. 6 is a schematic diagram of a module structure of the temperature adjustment system in this embodiment. The temperature adjustment system 200 in this embodiment includes: a fluid supply unit 210, a cooling and heating unit 220, and a fluid passage 230.
The fluid supply unit 210, the cooling and heating unit 220, the fluid passage 230 and the fluid pipeline inside the heat exchange assembly 264 are communicated with each other to form a closed circulation loop. The fluid supply unit 210 includes a water pump for circulating fluid in a reservoir tank and the reservoir tank. The water pump may be a piston pump, gear pump, vane pump, centrifugal pump, axial flow pump, or the like. The reservoir provides fluid for heat exchange to fluid passageway 230. The liquid storage tank is preferably a tank body with a heat preservation effect.
The cooling and heating unit 220 includes a cooling unit and a heating unit for cooling and heating the fluid, respectively.
As shown in fig. 3, the charging bin 161 of the charging rack 160 is a non-enclosed structure to facilitate heat dissipation. Each charging bin 161 is provided with a charging module 162 therein, and all the charging modules 162 are connected in parallel with an external power supply.
A temperature sensor is provided in the charging chamber 161, and the temperature sensor is used for acquiring the temperature of the battery pack 300. The temperature of the battery pack 300 is collected in real time through the temperature sensor, the refrigerating and heating unit 220 is controlled to heat or refrigerate the fluid when the temperature of the battery pack 300 is too low or too high, and the refrigerating and heating unit 220 does not work when the temperature of the battery pack 300 is at a normal temperature, so that the battery pack 300 is always in a proper working temperature range.
Specifically, a minimum temperature threshold and a maximum temperature threshold (the minimum temperature threshold and the maximum temperature threshold are respectively the minimum temperature and the maximum temperature of the normal operating temperature of the battery pack 300) are preset in the temperature adjustment system 200, and the controller of the temperature adjustment system 200 compares the temperature value collected by the temperature sensor with the two preset temperature thresholds, and then controls the operating state of the cooling and heating unit 220 according to the comparison result.
When the temperature value of the battery pack 300 collected by the temperature sensor is less than the lowest temperature threshold or greater than the highest temperature threshold, controlling the cooling and heating unit 220 to heat or cool the fluid output by the fluid supply unit 210, thereby increasing or decreasing the temperature of the battery pack 300; when the temperature value collected by the temperature sensor is greater than the minimum temperature threshold and less than the maximum temperature threshold, the cooling and heating unit 220 does not operate, the fluid output by the fluid supply unit 210 does not need to be heated or cooled, and the temperature of the battery pack 300 can be maintained within a normal range only through self circulation of the fluid. The specific process is as follows:
when the external environment temperature is low, for example, in cold winter, the temperature of the battery pack 300 is often lower than the minimum temperature for normal operation, and in order to ensure the best performance of the battery pack, the battery pack 300 needs to be thermally insulated. By controlling the heating unit of the cooling and heating unit 220 to heat the fluid, the heated fluid can transfer heat to the battery pack 300 to raise the temperature of the battery pack 300 during the circulation process of the fluid pipeline, and the temperature of the battery pack 300 is always kept in a proper temperature range through the continuous circulation of the fluid.
When the external environment temperature is high, for example, in hot summer, and since the battery pack 300 itself also emits heat during charging, the temperature of the battery pack 300 usually exceeds the normal operating temperature thereof, and in order to ensure the optimal performance of the battery pack, the battery pack 300 needs to be cooled. By controlling the cooling unit of the cooling and heating unit 220 to cool the fluid, the cooled fluid can absorb the heat of the battery pack 300 to reduce the temperature of the battery pack 300 in the circulation process of the fluid pipeline, and the temperature of the battery pack 300 is always kept in a proper temperature range through the continuous circulation of the fluid.
When the external environment temperature is relatively suitable, the cooling and heating unit 220 stops working, and does not heat or cool the fluid. The fluid in the normal temperature state circulates in the fluid pipe and exchanges heat with the battery pack 300, so that the temperature of the battery pack 300 can be maintained within an appropriate temperature range.
Each charging bin 161 is provided with a charging module 162 and a connecting socket 260, the charging module 162 is electrically connected to the connecting socket 260, and the connecting socket 260 is used for connecting the battery pack 300 so as to charge the battery pack 300. This one-to-one arrangement of the charging module 162 and the battery pack 300 facilitates heat dissipation of the charging module 162 than if the charging module 162 is centrally placed.
During the charging process of the battery pack, the charging module 162 also emits heat. When the external temperature itself is high, the heat emitted from the charging module 162 further affects the temperature of the battery pack 300, and the charging module 162 needs to be cooled. A fluid pipeline may be disposed in the charging module 162, and the fluid pipeline is also communicated with the fluid passage 230, so that the cooled fluid carries away the heat emitted by the charging module 162, and the charging module 162 is prevented from being damaged due to untimely internal heat dissipation.
In order to increase the heat dissipation efficiency of the charging module 162, a heat dissipation assembly 265 is further disposed in the charging bin 161, and the heat dissipation assembly 265 is disposed on the outer surface of the charging module 162. In this embodiment, the heat sink 265 is a plate with built-in fluid lines. In other embodiments, the heat sink assembly 265 may not have a built-in fluid line.
The heat dissipation assembly 265 may also be disposed at any position on the outer surface of the charging module 162 as required, and the number of the heat dissipation assemblies 265 may be set as required. In fig. 4, a heat sink 265 is provided on an upper surface of the charging module 162.
The heat sink 265 may also be disposed between the charging module 162 and the battery pack 300. When the heat sink 265 is located at the above position, it can dissipate heat not only from the charging module 162, but also from the battery pack 300.
Since the battery pack 300 needs to be heated when the external environment temperature is low, the internal temperature of the charging module 162 is raised by the heat emitted from the heat exchange assembly 264, which may cause the internal overheating and damage during the operation of the battery pack, and thus the charging operation of the battery pack 300 is affected, the heat insulation plate 266 is disposed between the heat exchange assembly 264 and the charging module 162. As shown in fig. 4, a heat insulation plate 266 is provided on the lower case of the charging module 162, and a heat exchange assembly 264 and a battery pack 300 are sequentially provided below the heat insulation plate 266. The heat shield 266 may insulate the charging module 162 from heat dissipated by the heat exchange assembly 264.
A stop valve 263 is disposed at the inlet of the front end of the built-in fluid pipeline of each charging module 162, so that the stop valve 263 can be closed when the external environment temperature is low, and the fluid is prevented from flowing through the inside of the charging module 162. This is because when the external temperature is low, the battery pack 300 needs to be kept warm, and at this time, the fluid flowing out of the cooling and heating unit 220 is hot, and the charging module 162 itself generates heat when operating, so that it is not necessary to raise the temperature of the charging module 162, and at this time, it is necessary to prevent the heated fluid from entering the charging module 162. Wherein, stop valve 263 prefers the electromagnetism stop valve, conveniently carries out automated control.
In other embodiments, when the battery pack 300 itself has a fluid line built therein, temperature adjustment of the battery pack 300 may be achieved by controlling the temperature of the fluid entering the built-in fluid line.
In other embodiments, the temperature of the battery pack 300 can be adjusted by the heat exchange assembly 264 in the charging chamber 161 and the fluid pipeline in the battery pack 300, specifically, the temperature of the fluid entering the heat exchange assembly 264 and the fluid pipeline can be controlled. Through adjusting the inside and outside of the battery pack 300 together, the temperature rise or the temperature drop of the battery pack 300 can be realized at an accelerated speed, so that the battery pack 300 is maintained in a proper working temperature range quickly, and the temperature adjusting efficiency is higher.
