Description

Technical Field

[0001] The invention relates to the technical field of vacuum tube maglev trains, and in particular to a power-exchange type vacuum maglev train and a rapid power-exchange method. Background Art

[0002] Battery pack rapid replacement technology (quick change) has been applied in new energy vehicles, including Tesla, BAIC New Energy, NIO, Zotye Auto, etc. Among them, BAIC New Energy's quick-change electric taxi EU300 has been widely promoted in Beijing. The battery quick-change time can be controlled within 5 minutes, and the quick-change reliability is high. The warranty life of the quick-change battery pack can reach 6 years and 600,000 kilometers (the warranty life of non-quick-change battery pack is only 5 years and 150,000 kilometers).

[0003] Automobile battery replacement technology is divided into manual battery replacement (Lifan Motors), semi-automatic battery replacement (Foton Motors), and fully automatic battery replacement (NIO, BAIC New Energy, Tesla). Figure 5 As shown. BAIC, Tesla, NIO and other pure electric vehicles have made achievements in the field of battery replacement, and have built a varying number of battery replacement stations across the country, achieving battery system replacement within 5-10 minutes.

[0004] However, the automatic charging and swapping station provided in the prior art is suitable for charging and swapping under normal pressure environment, and its battery swapping steps specifically include: confirming whether the vehicle enters the quick-swap position through the quick-swap position detection module; confirming the vehicle battery replacement information through the signal; the quick-swap control module confirms the start of the battery swap and cuts off the current of the battery pack at the same time; the battery pack quick-swap fixing module switch is turned on, so that the battery pack can be separated from the body suspension module; the quick-swap lifting platform takes out the battery pack; the quick-swap lifting platform installs the nearly fully charged battery pack on the car; the battery pack quick-swap fixing module switch is turned off, so that the battery pack is fastened to the body suspension module again; the battery pack is powered on and the new battery pack is electrically tested; after the electrical test is completed, it is ready to depart. This type of battery swapping technology is aimed at normal pressure environment. There is no need to adjust the pressure when swapping.

The battery pack electrical connection and thermal management connection module 23 is a specially designed electrical connector and thermal management connector, which enables the quick-change battery pack to be lifted up and down, moved forward and backward, and other paths to reach the specified position without manual operation to complete the plug-in connection, making the high and low voltage electrical and thermal management connections of the battery pack before and after replacement safer and more reliable. By setting a buffer layer, it can effectively meet the vibration, life and other technical requirements of the train. By setting a sealing layer, it can effectively limit the displacement of the plug-in connector, thereby ensuring the reliable connection of the battery pack.

[0047] The normal pressure acquisition module is used to restore the normal pressure environment of the vacuum pipe of the train section where the quick-change battery pack 20 is located. The vacuum acquisition module is used to restore the vacuum environment of the vacuum pipe of the train section where the quick-change battery pack 20 is located. The train quick-change control module is respectively connected to the normal pressure equipment compartment 10, the quick-change battery pack 20, the normal pressure acquisition module and the vacuum acquisition module. The train quick-change control module includes a position detection unit, a battery pack power detection unit, a battery pack model detection unit, a normal pressure control unit, a battery pack on-off detection unit, a vacuum control unit, a body suspension control unit, a quick-change start-stop control module and a pressure The detection unit and the battery pack on-off detection unit include an electrical connection detection protection circuit and a quick-change high and low voltage relay. The quick-change high and low voltage relay is used to realize the on and off of the quick-change battery pack. The electrical connection detection protection circuit is used to detect the disconnection and connection status of the quick-change battery pack. The quick-change start-stop control module can be used to control the disconnection or closing of the high and low voltage relays to confirm whether the battery needs to be replaced. The train quick-change control module enables the train to communicate with the battery swap station after entering the station, so that the train can accurately drive into the position where the battery pack can be replaced, and communicate the model of the battery pack that needs to be quickly replaced to confirm whether the battery is replaced. When it is confirmed that the battery pack needs to be quickly replaced, a quick-change start signal is issued, the battery electrical connection is cut off, and the vacuum pipe section corresponding to the battery pack is restored from vacuum to normal pressure through the normal pressure acquisition module, and pressure detection is performed through the normal pressure detection unit. When the vacuum pipe section corresponding to the battery pack is in a normal pressure environment, the normal pressure equipment cabin is opened and a signal is sent to open the fixed switch of the vehicle body suspension module so that the battery can be quickly removed. After the quick change is completed, it is detected whether the quick change is successful, a signal is sent to close the equipment normal pressure cabin, close the quick change relay, close the fixed switch of the vehicle body suspension module, and restore the vacuum pipe section corresponding to the battery pack from normal pressure to vacuum through the vacuum acquisition module.

[0048] In this embodiment, battery pack replacement specifically includes the following steps: detecting the remaining power of the quick-change battery pack by a battery pack power detection unit, and when the remaining circuit of the quick-change battery pack is less than a set threshold, the quick-change battery pack needs to be replaced. The position detection unit is used to detect whether the train has entered the set quick-change position. When the train is in the set quick-change position, the battery pack model detection unit is used to confirm the information of the battery to be replaced in the train; the vacuum pipe of the train section where the battery to be replaced is located is restored to normal pressure, and after a set time, it is detected whether the pressure outside the normal pressure equipment compartment 10 has returned to the normal pressure environment; when the pressure outside the normal pressure equipment compartment 10 has returned to the normal pressure environment, the quick-change control module confirms the start of the battery replacement, and at the same time cuts off the current of the battery pack to be replaced, opens the body suspension module, so that the battery pack quick fixing module can be separated from the body suspension module, and the battery pack to be replaced is detached from the body; the door of the normal pressure equipment compartment 10 is opened, so that the rapid lifting platform can enter the normal pressure equipment compartment where the battery pack is located, take out the battery pack to be replaced and install the fully charged battery pack corresponding to the information of the battery pack to be replaced on the body; the fully charged battery pack is electrically tested, and after the electrical test is completed, the door of the normal pressure equipment compartment 10 is closed; the environment outside the normal pressure equipment compartment 10 where the battery to be replaced is located is restored to a vacuum environment, and the rapid battery replacement of the vacuum maglev train is completed, and the train is ready to depart.

[0049] In summary, the present invention provides a battery-exchange type vacuum maglev train, which realizes the replacement of battery packs in vacuum pipe stations through the system design of battery replacement. The environmental pressure outside the battery pack needs to be adjusted before and after replacement.
