Description

Technical Field

[0001] The present invention relates to a distributed mobile vehicle battery replacement system. In addition, the present invention also relates to a distributed mobile vehicle battery replacement method and a battery pack with a built-in refrigerant cavity. The battery pack can be used in the distributed mobile vehicle battery replacement system. Background Art

[0002] Based on the global trend of green energy, the energy used by road vehicles and ships is gradually being replaced by electric power instead of fossil fuels. A major issue affecting the marketability of such electric mobile vehicles is endurance. Before the power carried is exhausted, it is necessary to be able to drive to the next charging station or battery replacement station to continue the next journey.

[0003] Ideally, when an electric vehicle is driven according to plan and when the transportation authority or transportation operating company has complete information on road traffic conditions, it will be possible to reasonably anticipate the electric vehicle's range and the locations where it needs to be charged or replaced, and make advance plans to achieve efficient management and support of transportation.

[0004] However, from the perspective of electric vehicles themselves, there are thousands or even tens of thousands of battery cells, and unexpected situations may occur at any time. When the number of battery cells is huge, some of them will continue to age or deteriorate, and the problem of insufficient power may occur without warning. From the perspective of single vehicle power management to the perspective of road traffic management, once a traffic accident occurs on the road, it is more likely to cause more vehicles to be blocked and unable to travel smoothly as expected; if we expand the view to, for example, national holidays on longer dates, when a large number of traveling vehicles flood into the traffic system, it will cause all electric vehicle drivers to constantly look for the next charging station or battery swap station on, for example, highways. The time required for charging / battery swapping is longer than that of fossil fuel vehicles. Even if the battery pack is replaced, it is necessary to consider that the replaced battery pack still needs time to be fully charged before it can be provided to the next vehicle. This also makes many electric vehicles waste more time waiting in line for charging / battery swapping than the actual driving time.

[0005] In the charging mode, not only the number of charging piles is fixed, the installation location is also fixed, and the vehicle must be parked before charging can begin. The charging time cannot be shortened arbitrarily, so it is difficult to make any adjustments to the above problems. Figure 1 and Figure 2 The rail-type battery swap station shown, and Figure 3 The mechanical arm shown is suspending the power station. Figure 1 In a rail-type battery replacement station, a vehicle that needs to replace a battery generally needs to travel onto the track 80 and be properly positioned using a guide device (not shown in the figure) before it can be replaced. Figure 2As shown in the figure, the used battery pack 90 is correctly removed from the vehicle and replaced with a new battery pack that has been charged to a certain threshold. In general, the battery pack of a container truck or trailer weighs more than 200 kilograms and is larger in size. The battery pack is usually installed at the rear of the truck head. Figure 3 The mechanical arm suspension battery swap station shown in the figure relies more on the suspension arm 82 to replace the battery pack 90. ​​Its automated operation is also more difficult, often requiring manual control and taking longer time. Limited by the weight of the battery pack, which is often hundreds of kilograms, and considering the volume of the battery pack itself and the setting of the charging equipment, no matter which one is used, electric vehicles still have to line up to drive to a fixed battery swap location, and then replace the battery pack in sequence. Therefore, it is impossible to solve the various traffic needs and emergencies mentioned above.

[0006] In contrast, the present invention will provide appropriate solutions to significantly enhance the flexibility and capabilities of transportation systems or transportation operators in solving the above-mentioned problems. Summary of the invention

[0008] In addition, the present invention also hopes to provide a distributed battery replacement method, by knowing the driving route of the mobile vehicle, adjusting the power standard of the replaceable battery pack, and shortening the charging time of the battery pack; and by using movable storage cabinets, towing vehicles and trailers, the mobility flexibility of the battery replacement station is greatly improved to meet actual needs.

[0009] In addition, the present invention also hopes to provide a battery pack with a built-in refrigerant, which is intended to effectively control the temperature rise of the battery pack during discharge, extend the service life of the battery pack, and through the refrigerant cavity with openings at both ends, the refrigerant cavity can be connected to the outside when the battery pack is charging, thereby fully achieving temperature control of the charging process.

[0011] In addition, the present invention provides a distributed mobile vehicle battery replacement method, which is used in a distributed mobile vehicle battery replacement system, and can be used for at least one mobile vehicle equipped with at least one battery pack to replace the aforementioned battery pack, and the aforementioned mobile vehicle further has at least one installation port for installing the aforementioned battery pack.

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. These embodiments should be understood to be only used to illustrate the present invention and not to limit the scope of protection of the present invention. After reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent changes and modifications also fall within the scope defined by the claims of the present invention.

[0031] like Figure 4-6As shown, the distributed battery exchange system provided by the first preferred embodiment of the present invention includes a movable storage cabinet 1. In this embodiment, a standard container is modified into a container with multiple rechargeable storage tanks 10 as an example. Therefore, when the standard container is parked in a predetermined area such as a highway rest stop, on the one hand, multiple battery packs 90 placed in the storage tanks can be charged, and at the same time, battery packs that have been charged to a predetermined standard can be provided to a mobile vehicle 9 waiting for battery exchange, which is an electric vehicle in this embodiment. The system includes at least one towing and moving vehicle 2. In this embodiment, an automatic driving forklift is used as an example. The towing and moving vehicle 2 includes a moving device 20 and a towing device 22. By means of the moving device 20 in the front, not only can the old battery pack 94 be removed from the installation port 92 of the mobile vehicle, but also the new battery pack 90 can be moved and installed to the aforementioned installation port, and the old battery pack can be placed in the storage tank 10 or the battery pack charged to a predetermined standard can be taken out from the storage tank 10; the towing device 22 behind the forklift can be connected to tow a trailer 3, and the trailer 3 has a plurality of temporary storage ports 30 for temporarily storing battery packs.

[0032] Under normal circumstances, the movable storage cabinet 1 is parked at a predetermined position in the rest stop, and the forklift can place multiple battery packs that have been charged to, for example, 90% of power on the trailer at the rear, and gradually replace the battery packs for the electric vehicles parked in the planned battery replacement parking spaces one by one. As long as the mobile vehicle is provided with a positioning member 96, the self-driving forklift can identify the positioning member of the electric vehicle to replace the battery pack according to the measuring device 24 it possesses; the self-driving processing device 26 receives the measurement result of the aforementioned measuring device 24 and drives the self-driving vehicle to stop at the disassembly and installation position corresponding to the aforementioned installation port 92 to replace the battery pack.

[0033] In the case where the number of vehicles that need to replace batteries increases, according to the present invention, as long as the number of movable storage cabinets 1 is appropriately increased at the fixed charging base, and the towing and moving vehicles 2 and trailers 3 are increased to two or three times the number of movable storage cabinets as appropriate, the congestion can be alleviated in response to the increased demand for vehicles.

[0034] On the other hand, the temperature control of the battery pack is very important. The most common heating problems are in the fast charging and fast discharging stages. Due to the huge power density of the battery pack of electric vehicles and strict safety requirements, only the rechargeable battery with the battery pack fixed in the vehicle can easily design cooling pipes to allow coolant such as water to flow through each battery cell for temperature control; in contrast, if a cooling system is installed in a detachable battery-swap battery pack, if an air-cooled air flow channel is used, it will cause safety structural risks. If a liquid cooling pipeline is used, it cannot ensure a good watertight connection with the water pump installed on the vehicle itself, making it highly difficult to set a cooling device in the battery-swap battery pack without increasing the structural or watertight risks. However, actual tests show that during the driving of a general mobile vehicle, the real rapid discharge will only occur in emergency acceleration and will not last for a long time. During normal driving, the heat generated by the entire battery pack under normal circumstances is only equivalent to a hair dryer of about kilowatts. It may not be necessary to continuously flow a large amount of coolant to carry heat energy, but it is only during the charging stage that large currents and high heat that last for a period of time will often occur.

[0035] Therefore, the battery pack 90 disclosed in the present invention is as follows: Figure 7 and Figure 8 As shown, there is a shell 60, and the battery core 62 is discharged in the shell 60 as in the common battery pack design, and is charged by the conductive connection between the charging port and the storage tank. The battery pack of the present invention is special in that a refrigerant cavity 64 is provided in the shell 60. In this embodiment, the refrigerant cavity 64 is a single pipe that bends back and forth, and openings 640 are formed at both ends of the shell 60; therefore, when the battery pack 90 is placed in the storage tank for charging, the opening 640 can be connected to the corresponding interface of the storage tank 10, so that the refrigerant circulation system in the mobile storage cabinet or even the base can be connected, which can not only ensure the ambient temperature during high-current rapid charging, improve charging safety and efficiency, but also do not need the battery pack or electric vehicle to bear the energy consumption of heat dissipation. Until the battery pack 90 is fully charged, the corresponding cover 642 is used to close the opening 640, so that the refrigerant cavity 64 becomes closed again. This passive refrigerant cavity 64 greatly simplifies the structural design of the battery pack 90.

[0036] As described above, when the battery pack 90 is installed on an electric vehicle to supply power, the amount of current generated is much lower than the input current of the fast charging process, so the heat generation is also in a relatively low range. At this time, it is only necessary to allow the refrigerant in the refrigerant cavity to absorb the heat energy generated by the battery core by itself according to heat conduction. Since the shell 60 of the huge battery pack weighing one or two hundred kilograms is very large, a passive closed refrigerant cavity 64 can naturally be planned to accommodate a large amount of refrigerant, such as tens of kilograms. Even if water is used as an example, it has a very considerable heat capacity and can be effectively absorbed during the driving process of the mobile vehicle, effectively ensuring that the heat generated by the battery pack is absorbed by the refrigerant, and the temperature rise is limited, so that the operating temperature of the battery pack is effectively reduced. On the one hand, the discharge efficiency of the battery pack is ensured, and on the other hand, the service life of the battery pack is ensured.

[0037] Furthermore, when a traffic jam occurs on a highway due to a car accident or unexpected situation, the trapped electric vehicles can only watch the power consumption continue to increase, worrying whether they can reach the subsequent reserved charging station as expected, or even run out of power and break down, causing more serious congestion. However, according to the second preferred embodiment of the present invention, if Fig. 9 As shown, the above-mentioned movable storage cabinet itself can be modified from a standard container, so as long as a tractor 4 is added, the position can be moved. When the mobile vehicle in this case is an electric vehicle that is communicatively linked to the control center 5, the battery power status of the mobile vehicle and the future travel plan of the mobile vehicle can be obtained at any time through the information exchange interface 50 of the control center in step 71.

[0038] The control center 5 obtains the battery power status of the mobile vehicle and the future travel plan of the mobile vehicle via the information exchange interface 50, and determines the required power of the mobile vehicle according to the future travel plan in step 72, and determines that the mobile vehicle 9 is stuck on the highway according to the current road conditions; the control center 5 determines in step 73 whether the battery power has been consumed to a standard that requires emergency rescue. If the power is sufficient, no processing is required. Once it is found that the power of the mobile vehicle 9 has been reduced to a dangerous standard that requires emergency rescue, at least one tractor is instructed in step 74. For example, a towing truck drives into the movable storage cabinet 1 and is transported together with it, and through the communication device 40 of a towing truck 4, the towing truck 4 is instructed to tow and move the aforementioned movable storage cabinet to a specified location; because the control center 5 determines that according to the future driving plan of the aforementioned mobile vehicle, the required power of the aforementioned mobile vehicle can be known; therefore, when the electric vehicle requiring emergency rescue meets the towing truck, in step 75, the control center 5 instructs the towing truck in the container to select and move the battery pack with a storage power greater than and closest to the aforementioned required power among all the battery packs in the movable storage cabinet.

[0039] Generally, when a traffic jam occurs on a highway, there are often more than one or two vehicles trapped. Even if some electric vehicles may have 50% or 60% of the remaining power in the battery pack, they may still worry about insufficient power and try to squeeze into the rest stop to queue up for charging or battery replacement. Therefore, according to the disclosure of the present invention, since the above-mentioned movable storage cabinet is towed by the tractor 4 to a temporary location convenient for battery replacement, it may not be charged. In order to reassure the above-mentioned car owner who has only 50% to 60% of the remaining power, it is still possible to replace the battery for him, and replace the battery pack with a more abundant power for this vehicle, so as to reduce one electric vehicle that squeezes into the rest stop. On the other hand, if some vehicles are short-distance vehicles with a relatively close destination, they can reach their destination as long as the power demand is not high, and they can even leave the highway. In step 76, the towing and moving vehicle can immediately replace the battery pack with 50% to 60% remaining power that has just been replaced on the above-mentioned vehicle with this short-distance vehicle, replacing the old battery pack with extremely low power, such as only 15% remaining power, currently used by the short-distance mobile vehicle, so as to avoid that each vehicle has to wait for the battery pack to be fully charged to 90% or even 95%, and the waiting time in the queue also consumes the battery power of all the queued vehicles simultaneously; and in step 77, the control center records the remaining power of each old battery pack that has just been removed, and then the towing and moving vehicle moves the aforementioned old battery pack back to the storage tank of the movable storage cabinet. Due to the disclosure of the present invention, the previous charging mode, which used to be based on industrial production standards and required each battery pack to be fully charged to a fixed standard, has been transferred to a floating standard charging mode that is sufficient for use, and even a transfer operation mode in which the position of the battery swap station is dynamically changed, can make the above-mentioned congestion situation easier to alleviate.

[0040] After all the charged battery packs in the movable storage cabinet have been used up, the tractor 4 will pull the movable storage cabinet filled with empty battery packs back to a charging power supply base in step 78, and supply power to each storage tank where the old battery pack is placed, so as to charge the old battery packs with low residual power; finally, in step 79, the control center will continuously monitor and record the charging status of each old battery pack. Of course, as those familiar with the technical field can easily understand, when the movable storage tank is towed and dropped to establish a temporary battery swap station, the tractor can leave this temporary battery swap station and establish another temporary battery swap station according to the situation, or prepare the next set of movable storage cabinets for this temporary battery swap station. All these changes should be deemed to be covered by the following rights scope of the present invention. In addition, although the above embodiment takes electric vehicles as an example of mobile vehicles, even light electric aircraft and electric boats can use the technology disclosed in the present invention to exchange batteries, which is also covered by the rights scope of the present invention.

[0041] In summary, the distributed mobile vehicle battery replacement system, method and system provided by the present invention use a built-in refrigerant battery pack, which can not only allow the distributed battery replacement system to flexibly increase or decrease various configurations according to road conditions or temporary needs of mobile vehicles, but also effectively improve the efficiency of battery replacement. And by using movable storage cabinets, towing moving vehicles and trailers, temporary battery replacement stations can be easily changed to improve the flexibility of use. The present invention also adjusts the power standard of the replaceable battery pack by knowing the driving route of the mobile vehicle, so that when the demand for battery replacement increases greatly, the power standard can float to be sufficient, shortening the charging time of the battery pack. In particular, the present invention provides a battery pack with a built-in refrigerant. During the high-current fast charging process, the refrigerant cavity can be connected to the refrigerant supply cycle in the storage tank to effectively control the safety and efficiency of the battery pack charging; as for the temperature rise during discharge, it can also be absorbed by the heat capacity of the refrigerant in the closed refrigerant cavity to extend the service life of the battery pack. Therefore, it not only provides efficient and flexible battery replacement services, but also effectively controls the power demand of mobile vehicles, and can especially save a lot of blocking manpower and time costs.
