Description

Technical Field

[0001] This utility model relates to the field of battery swapping station technology, and in particular to a mobile charging and discharging battery swapping vehicle. Background Technology

[0002] With the increasing popularity of electric vehicles, the demand for battery swapping facilities is growing. Existing battery swapping stations are mostly fixed, which suffers from high construction costs and inflexible layout. The construction of fixed charging stations involves multiple complex processes, including urban planning, land use permits, environmental impact assessments, and traffic and power supply considerations, leading to cumbersome project initiation and approval procedures. Furthermore, the construction cycle for fixed charging stations is lengthy, typically taking several months, and requires large areas of land for new factory buildings and equipment installation, making large-scale construction on urban main roads impractical. Meanwhile, electric vehicle users must drive their vehicles to fixed charging stations for battery swapping, a process that not only consumes energy but also shortens the vehicle's effective driving range and causes inconvenience.

[0003] Fixed charging stations face challenges in urban areas due to their large footprint, high investment costs, and difficult deployment, hindering their widespread adoption. This significantly impedes the promotion and application of electric vehicles, especially in remote areas or temporary large-scale events, where fixed charging stations struggle to meet the demand for fast and convenient charging. Therefore, a more flexible, lower-cost, and easier-to-deploy battery swapping solution is needed. Utility Model Content

[0037] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0038] This specific embodiment discloses in detail a mobile energy replenishment, charging, discharging, and battery swapping vehicle, such as... Figures 1 to 9 As shown.

[0039] The charging and discharging battery swapping vehicle 1 includes a tractor unit 11 and a flatbed carriage 12. The flatbed carriage is moved by the tractor unit. The charging and discharging battery swapping vehicle 1 also includes a power battery box 2, a locking mechanism 6, a discharger 3, an inverter 4, and a discharge gun 5. Several power battery boxes are provided. A fixed bracket 121 is welded on the flatbed carriage. The fixed bracket is arranged along the length of the flatbed carriage.

[0040] The power battery box includes an upper box 21 and a vehicle base 22. The vehicle base is fixedly installed on the fixed bracket along the fixed bracket by fixing pieces 122 at intervals. The upper box is locked to the vehicle base by a locking mechanism. The vehicle base includes a base connector, and the upper box includes an upper box connector. The base connector can be electrically connected to the upper box connector. The upper box includes a bottom frame 211.

[0041] The locking mechanism includes a positioning pin 61, a locking seat 63, and a locking cylinder 64, which are located on the upper end of the vehicle base. The output end of the locking cylinder is provided with a locking tongue 641. The bottom frame is provided with a corresponding locking fixing support block 65. The upper end of the locking fixing support block has a sloping stop surface 651. The bottom frame is provided with a positioning hole 62 that cooperates with the positioning pin. The locking seat is located on the upper periphery of the vehicle base. Specifically, the vehicle base is a rectangular frame structure. The locking seat is provided on all four sides of the vehicle base. The side surface of the locking seat facing the bottom frame is provided with an arc-shaped spring piece 631.

[0042] The locking process of the locking mechanism is as follows: the upper box is mounted on the vehicle base, the positioning pin is inserted into the positioning hole, and the arc-shaped spring abuts against the inner side of the bottom frame, driving the locking cylinder to work, so that the locking tongue abuts against the inclined surface. The locking tongue also has an inclined surface, so the two can fit together perfectly. This completes the process of locking the upper box to the vehicle base. A charging gun holder 221 is provided on one side of the vehicle base, and a battery pack system 215 and a thermal management system 216 are provided inside the upper box.

[0043] The discharge inverter is connected to the base electrical connector and the discharge gun via cables and communication lines, respectively, so that the power battery box system and the discharge system form a complete energy storage and discharge system. It can be towed by a tractor to a designated area for charging, discharging, and energy swapping operations.

[0044] In mains power usage scenarios, inverter 4 converts the power stored in the power battery box 2 into 220V AC power for use by the mains power user unit 72. For example, household appliances such as induction cookers can be connected to the inverter output to use the electrical energy stored in the power battery box.

[0045] Preferably, the flatbed carriage is a 13-meter flatbed carriage, the bottom of the flatbed carriage is provided with a discharge gun storage cabinet 123 for storing the discharge gun, and the rear of the flatbed carriage is provided with a rear baffle 124 to prevent the discharge gun from accidentally sliding out during the journey.

[0046] Using the above-described charging method for a mobile charging and battery swapping vehicle: The vehicle travels to a designated charging station, and the operator connects the charging gun of the charging pile 8 at the charging station to the charging gun socket of the power battery box, initiating the charging process and completing the charging process. The battery box has six units, which are charged sequentially.

[0047] It is worth noting that during the charging process, the power is delivered to the battery pack system 215 via the high voltage box 213 through the line system 214 to store electricity. During the charging process, the heat is transported to each battery pack system by the thermal management system 216 through the water system 217 for thermal management and balance.

[0048] Using the above-mentioned mobile charging and battery swapping vehicle's discharge method: When the charging and battery swapping vehicle travels to the designated discharge station, the operator connects the discharge gun equipped on the charging and battery swapping vehicle to the charging interface of the new energy vehicle 71, and starts the discharge process. This process obtains the stored electrical energy from the power battery box in the form of constant power DC electricity through the discharge module of the discharge machine, and transmits it to the new energy vehicle, thereby completing the discharge process.

[0049] Furthermore, in the case of mains power usage, an inverter is used to output the power stored in the power battery box in constant power DC form.

[0050] Using the above-mentioned mobile charging and swapping vehicle's battery swapping method: The charging and swapping vehicle travels to the designated battery swapping station. The operator follows the instructions and restrictions of the parking guidance system 92 within the battery swapping station 9 to ensure that the charging and swapping vehicle is parked in the correct battery swapping area, and starts the battery swapping procedure. The battery box positioning system 92 within the battery swapping station locates the power battery box to be replaced and performs the unlocking action of the power battery box. The battery swapping robot 93 within the battery swapping station drives the gripping tool to grab the power battery box 94 and replace it with a fully charged power battery box 95 from the battery swapping station, which is then installed on the charging and swapping vehicle, thus completing the battery swapping process.

[0051] It is worth noting that the discharger in the above embodiment is a DC to DC discharger.
