Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy heavy equipment, in particular to a double-channel expanded battery swap station and a battery swap method. BACKGROUND

[0002] With the large-scale application of new energy heavy equipment (such as electric mine trucks and electric logistics new energy heavy equipment), the battery swap mode gradually replaces the traditional charging mode as the mainstream choice for new energy heavy equipment energy supply because it can quickly supplement energy. Early new energy heavy equipment battery swap stations mostly use the structure design of "single channel + fixed charging bin": only one battery swap channel is provided, new energy heavy equipment needs to be queued to swap batteries one by one, and the battery swap mechanism can only carry batteries between the channel and the fixed charging bin. This design can meet the needs in scenarios where the operation density of new energy heavy equipment is low, but with the increasing demand for transportation efficiency in the logistics and mining industries and the increasing number of new energy heavy equipment, the existing battery swap stations gradually expose technical defects that are difficult to adapt to high-load operations, specifically as follows:

[0003] I. Weak actual service capacity caused by mismatch between theoretical capacity and actual battery swap peak

[0004] Most existing new energy heavy equipment battery swap stations are designed with a single channel and have seven spare batteries. Theoretically, a new energy heavy equipment battery swap station with seven spare batteries can achieve 168 theoretical service capacities per day. However, due to the work and rest habits of new energy heavy equipment drivers, battery swap demand often occurs in a short period of time (such as peak container transfer in ports and shift change periods in mines), so existing new energy heavy equipment battery swap stations generally cannot achieve theoretical service capacity, resulting in congestion and waiting for full batteries during vehicle battery swap; new energy heavy equipment needs to wait for more than 30 minutes, which seriously affects transportation efficiency and cannot meet the demand for multiple vehicle battery swaps.

[0005] II. Single operation strategy, not adapted to multiple scenarios

[0006] The operation mode of existing battery swap stations is fixed and can only perform the basic process of "removing depleted batteries - installing full batteries - charging depleted batteries", lacking the ability to dynamically adjust according to operation load and electricity price period: during the battery swap low period (such as at night), the full batteries in the charging bin are idle and cannot fully utilize the low electricity price during the valley period for energy storage; during the peak electricity period, the excess full batteries cannot be reversely transmitted to the power grid, missing the opportunity for electricity price arbitrage. SUMMARY

[0007] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present application is to provide a double-channel expanded battery swap station and a battery swap method to solve the problems of substandard actual service capacity of new energy heavy equipment battery swap stations and single operation scenario in the prior art.

[0008] To solve the above technical problems, the application provides a double-channel expansion battery replacement station for replacing batteries for new energy heavy equipment, comprising:

[0009] a charging base and a battery replacement channel arranged on both sides of the charging base, the charging base being provided with a plurality of battery charging compartments, a battery replacement battery arranged on the battery charging compartment, and a transfer compartment, and the battery replacement channel being provided with a sensing device;

[0013] As a more preferred mode, the double-channel expansion battery replacement station further comprises a battery replacement support arranged between the two battery replacement channels, and the charging base is arranged in the battery replacement support; the beneficial effects of which are that the battery replacement support is arranged between the two battery replacement channels, providing a stable installation carrier for the charging base, and enhancing the installation stability of the battery replacement mechanism. The support structure makes the charging base and the double battery replacement channels form a compact integrated layout, reduces the overall land occupation area of the battery replacement station, optimizes the space utilization rate, and can protect the internal components of the charging base from external collision, prolonging the service life of the equipment.

[0014] As a more preferred mode, the battery replacement mechanism comprises a battery replacement track arranged on the top of the battery replacement support and a telescopic robot slidingly arranged on the battery replacement track, the battery replacement track extending to the top of the battery replacement channel on both sides; the beneficial effects of which are that the battery replacement track is arranged on the top of the battery replacement support and extends to both sides of the battery replacement channel, providing a stable sliding guide for the telescopic robot, and ensuring the accurate carrying of the robot between the charging base and the battery replacement vehicle. The design of the telescopic robot can flexibly adjust the working radius, adapt to the battery replacement demand in different positions, and the track-type moving mode makes the battery carrying more stable and efficient, reduces the risk of battery collision and damage, and improves the continuity of the battery replacement process.

[0015] As a more preferred mode, the double-channel expansion battery swap station further comprises a channel rain shed connected with the battery swap support and arranged above the charging base and the two-side battery swap channels; the beneficial effects of which are that the channel rain shed arranged above the charging base and the battery swap channels can effectively shield rain, sunlight, dust and other external environmental factors, protect the battery swap vehicle, the battery swap mechanism and the electrical components of the charging base, avoid equipment failure caused by environmental impact, and prolong the service life of the equipment. At the same time, the rain shed provides a sheltered space for the battery swap operation, improves the operation comfort of the operator, and ensures that the battery swap station can still operate normally in bad weather.

[0016] As a more preferred mode, the power transmission device is a power transmission vehicle; the beneficial effects of which are that the power transmission device adopts the power transmission vehicle, which can automatically complete the transportation and supply of full-power batteries without manual driving, reduce labor costs, and improve the automation level of battery supply. The power transmission vehicle can be flexibly dispatched to supplement full-power batteries in time according to the battery inventory of the battery swap station, especially during the battery swap peak, which can quickly respond to the demand, avoid battery shortage leading to battery swap stagnation, and enhance the operation flexibility of the battery swap station.

[0017] As a more preferred mode, the power transmission vehicle comprises a vehicle frame, a plurality of drive wheels arranged at the bottom of the vehicle frame, and a bottom support arranged on the vehicle frame, and the power transmission battery compartment is arranged on the bottom support; the beneficial effects of which are that the vehicle frame and the drive wheels of the power transmission vehicle are designed to have good mobility, which can flexibly drive in the battery swap station and the surrounding area, and adapt to different supply routes. The bottom support provides stable support for the power transmission battery compartment, ensures that the battery is not easily displaced or collided during transportation, protects the structural integrity of the battery, and at the same time, the structural design of the bottom support facilitates the quick taking and placing of the battery by the battery swap mechanism, and improves the supply efficiency.

[0018] As a more preferred mode, the sensing device comprises a displacement sensor and an image sensor, and the control unit further determines whether the new energy heavy equipment reaches the designated battery swap position through the displacement sensor, and simultaneously performs the code scanning operation on the depleted battery through the image sensor; the beneficial effects of which are that the displacement sensor can accurately determine the designated battery swap position of the new energy heavy equipment, ensure the accurate alignment of the battery swap mechanism and the vehicle battery installation position, improve the accuracy of the battery swap operation, and avoid the failure of the battery swap caused by positioning deviation. The code scanning operation of the image sensor on the depleted battery can quickly identify the battery information, facilitate the battery management and scheduling of the control unit, optimize the battery swap strategy, and improve the intelligent level of the battery swap process.

[0019] As a more preferred mode, the double-channel battery replacement station comprises a plurality of battery delivery devices to meet the peak operation needs of battery replacement; the beneficial effects of which are that the configuration of the plurality of battery delivery devices can be flexibly scheduled according to the operation needs of the peak of battery replacement, the battery supply capacity is greatly improved through simultaneous supply of full batteries by multiple vehicles, and the battery replacement stagnation caused by the untimely supply of a single battery delivery device is avoided. The multiple battery delivery devices can also realize peak-shaving supply, and the remaining devices work normally when part of the devices are charging or being maintained, thereby ensuring the continuous and stable operation of the battery replacement station and improving the operation reliability.

[0020] To solve the above problems, the application also provides a double-channel expansion battery replacement method for new energy heavy equipment using the above double-channel expansion battery replacement station, comprising:

[0021] Peak operation scenario of battery replacement: the new energy heavy equipment enters the battery replacement channel, and the control unit determines the battery replacement channel entered by the new energy heavy equipment through the sensing device;

[0022] The control unit performs different battery replacement strategies according to the power conditions of the battery replacement batteries on the charging base and the battery delivery device;

[0023] When the battery replacement batteries on the charging base are in a full power state, first, the battery replacement mechanism is controlled to move to the battery replacement channel where the new energy heavy equipment is located, the depleted battery of the new energy heavy equipment is removed, and is carried to the transfer warehouse of the charging base; then the battery replacement mechanism is controlled to remove the battery replacement battery in the full power state on the charging base, and is carried and replaced to the new energy heavy equipment; then the battery replacement mechanism is controlled to carry the depleted battery in the transfer warehouse to the battery charging warehouse for charging; finally, the new energy heavy equipment completes the battery replacement and exits the battery replacement channel;

[0024] When the battery replacement batteries on the charging base are all in a depleted state and the battery delivery device is in a full power state, first, the battery delivery device is controlled to move to the other battery replacement channel opposite to the battery replacement channel where the new energy heavy equipment is located; then the battery replacement mechanism is controlled to move to the battery replacement channel where the new energy heavy equipment is located, the depleted battery of the new energy heavy equipment is removed, and is carried to the transfer warehouse of the charging base; then the battery replacement mechanism is controlled to remove the battery replacement battery in the full power state on the battery delivery device and directly carry it to the new energy heavy equipment; finally, the battery delivery device exits the battery replacement channel, and the new energy heavy equipment completes the battery replacement and exits the battery replacement channel;

[0025] In the valley operation scenario of battery replacement: when the battery replacement batteries on the charging base are all in a full power state and there are depleted batteries on the battery delivery device, first, the control unit controls the battery delivery device to run to the battery replacement channel; then the battery replacement mechanism carries the depleted battery to the transfer warehouse; then the battery replacement mechanism carries the battery replacement battery in the full power state on the charging base to the battery delivery device until all the depleted batteries on the battery delivery device are replaced by the battery replacement batteries in the full power state; finally, the battery delivery device exits the battery replacement channel.

[0026] As a more preferred mode, the battery swap valley operation scenario further includes that, when in the valley power period, the control unit charges the battery swap battery by using the charging base; when in the peak power period, the charging base and the power transmission device reversely transmit power to the power grid; the beneficial effect is that the design of charging in the valley power period and reversely transmitting power in the peak power period during the battery swap valley can fully utilize the low-price power energy storage in the valley power period, reduce the charging cost; the power transmission to the power grid in the peak power period can realize energy recycling, increase the additional income of the battery swap station, relieve the power supply pressure of the power grid at the peak time, realize the efficient and optimal allocation of energy, and improve the economic value and environmental protection benefit of the battery swap station.

[0027] As a more preferred mode, the peak power period in the battery swap valley operation scenario further includes that the power transmission device can reversely transmit power to the power grid through the grid-connected cabinet directly, or reversely transmit power to the power grid through the charging base by swapping the full-power battery to the charging base; the beneficial effect is that the power transmission device can reversely transmit power directly through the grid-connected cabinet or indirectly through the charging base, providing a flexible power transmission mode selection to adapt to different power grid access requirements. The two power transmission modes can be flexibly switched according to the actual situation to ensure smooth reversely power transmission process, further improve the energy utilization efficiency and the operation flexibility of the battery swap station.

[0028] As a more preferred mode, in the battery swap peak operation scenario, when there are multiple battery swap batteries in the full-power state on the charging base, two battery swap channels are simultaneously enabled for battery swap, and the directions of the two battery swap channels are opposite to meet the battery swap demand of the two-way lane; the beneficial effect is that the two battery swap channels are simultaneously enabled and the directions are opposite during the battery swap peak, which can meet the battery swap demand of the two-way lane, adapt to the road traffic rules, and avoid the reverse or congestion of the battery swap vehicle. The double-channel parallel battery swap can double the battery swap efficiency, greatly shorten the vehicle queuing waiting time, improve the peak processing capacity of the battery swap station, and better cope with the battery swap peak pressure.

[0029] As a more preferred mode, in the battery swap peak operation scenario, the power transmission devices of different battery swap stations are dispatched to realize the peak-shaving operation of the battery swap peak in different regions; the beneficial effect is that the peak-shaving operation is realized by dispatching the power transmission devices of different battery swap stations, which can balance the distribution of battery resources in different regions, avoid the operation limitation of some battery swap stations due to battery shortage, fully utilize the transportation capacity of idle power transmission devices, and improve the utilization rate of the overall battery resources. The peak-shaving scheduling mode enhances the cooperative operation capability between multiple battery swap stations, improves the operation efficiency and stability of the regional battery swap network.

[0030] As a more preferred mode, the corresponding time period when the battery replacement peak operation scene and the battery replacement valley operation scene are started is obtained in combination with historical battery replacement data information and trend statistics; its beneficial effect lies in that the peak and valley periods are determined in combination with historical battery replacement data and trend statistics, so that the operation strategy of the battery replacement station is more in line with the actual demand, and resource waste or insufficient operation caused by blind scheduling is avoided. The data-driven time period division can accurately predict the battery replacement demand, and the preparation work such as battery storage and power transmission device scheduling can be done in advance, so as to optimize the operation efficiency of the battery replacement station, and improve the user experience and operation economy.

[0031] As described above, the double-channel expanded battery replacement station and the battery replacement method of the application have the following beneficial effects:

[0032] The double-channel expanded battery replacement station of the application is provided with double battery replacement channels on both sides of the charging base, and can simultaneously or alternately replace batteries for two new energy heavy equipment, greatly improving the battery replacement efficiency and relieving the battery replacement peak congestion. The charging base is integrated with multiple battery charging warehouses and transfer warehouses, realizing the integration of storage, charging and transfer of battery replacement batteries; the power transmission device can supplement the fully charged batteries, and the intelligent linkage of the control unit and the sensing device realizes the automation of the battery replacement process, reduces the manual intervention, adapts to the high-frequency battery replacement demand of new energy heavy equipment, and improves the convenience and stability of battery replacement.

[0033] The double-channel expanded battery replacement method of the application formulates differentiated strategies for the battery replacement peak operation scene and the battery replacement peak operation scene: in the battery replacement peak operation scene, the fully charged batteries of the charging base are used preferentially, and the power transmission device is started to supplement when insufficient, to ensure efficient and continuous battery replacement, and the vehicle flow efficiency is improved through double-channel battery replacement; in the valley, the charging base is used to supplement the fully charged batteries of the power transmission device, to realize battery energy storage and optimize battery resource allocation; moreover, the double-channel and bidirectional battery replacement mechanism design realizes the direct auxiliary battery replacement of the power transmission device in the battery replacement channel, realizes the battery shortage in the peak scene, and finally, the double-channel expanded battery replacement method of the application discloses in detail the energy supplement strategy and peak shaving and valley filling strategy in the peak and valley power periods, further optimizes the multi-scene operation strategy of the double-channel battery replacement station and the power transmission device, improves the operation efficiency, and increases the operation income.

[0034] In summary, the double-channel expanded battery replacement station and the battery replacement method of the application solve the problems of substandard actual service capacity of new energy heavy equipment battery replacement station and single operation scene in the prior art through the double-channel battery replacement mechanism and the supporting multi-scene and multi-period operation strategy.
