[0033] Referring to Figures 1 to 3 , an RV chassis assembly 100 provided in an embodiment of the present application includes a chassis 12 and an energy storage device 14. The chassis 12 is provided with a plurality of storage compartments 16 , each of which is provided with an electrical connection mechanism 22 . The energy storage device 14 includes a control device 18 and at least one battery device 20 . Each battery device 20 is housed in a corresponding storage compartment 16 , and the battery device 20 is connected to the electrical connection mechanism 22 . The control device 18 communicates with the battery device 20 via the electrical connection mechanism 22 .

[0034] In the above-mentioned RV chassis assembly 100, the battery device 20 can be arranged in the storage compartment 16 of the chassis 12. The battery device 20 is communicated with the control device 18. The battery device 20 does not need to occupy the indoor living space of the RV 200, ensuring that the indoor living space of the RV 200 is sufficient.

[0035] Specifically, the RV chassis assembly 100 can be applied to self-propelled RVs, trailer RVs, and the like. The multiple storage compartments 16 can be two storage compartments 16 or more than two storage compartments 16. In Figure 2, the number of storage compartments 16 is five, and the five storage compartments 16 are arranged in the front-to-back direction. In one embodiment, the control device 18 is accommodated in one of the storage compartments 16, and the four battery devices 20 are respectively accommodated in the four storage compartments 16. Optionally, the chassis 12 can be made of stainless steel or aluminum alloy. It can be understood that in other embodiments, the control device 18 can be arranged in the indoor space or other locations of the RV 200.

[0036] The output voltage of a single battery device 20 includes, but is not limited to, 12V, 24V, 48V, etc. When the battery device 20 is housed in the storage compartment 16, multiple battery devices 20 can be connected in parallel, and the total system voltage is low voltage. For example, the voltage and capacity of a single battery device 20 is 48V800Ah. When the chassis 12 has one battery device 20 and one control device 18, the system voltage and capacity are 48V800Ah. When the chassis 12 has two battery devices 20 and one control device 18, the system voltage and capacity are 48V1600Ah. When the chassis 12 has three battery devices 20 and one control device 18, the system voltage and capacity are 48V2400Ah. When the chassis 12 has four battery devices 20 and one control device 18, the system voltage and capacity are 48V3200Ah. It will be understood that multiple battery devices 20 are not limited to being connected in parallel, but can also be connected in series, or in series-parallel.

[0037] It should be noted that the present application does not specifically limit the number and chemical system of the battery devices 20. The number of storage compartments 16 provided in the chassis 12 is not less than the total number of battery devices 20 + control devices 18. In Figure 2, the chassis 12 is provided with five storage compartments 16, and the total number of battery devices 20 + control devices 18 is five. The RV chassis assembly 100 of the present application can be an expandable chassis 12. Specifically, when the chassis 12 is provided with a battery device 20 and a control device 18, it can be operated to support the daily electricity consumption of the RV 200. Subsequently, the idle storage compartments 16 can be used to accommodate more battery devices 20. The battery device 20 is communicated with the control device 18 through the electrical connection mechanism 22, in order to expand the capacity of the battery system.

[0038] When the battery device 20 and the control device 18 are both accommodated in the accommodating compartment 16, the control device 18 can be communicatively connected to the battery device 20 through the electrical connection mechanism 22. Optionally, the control device 18 includes a control box and an integrated charging and inverter machine, which can realize charging and external discharging of the battery device 20. In one embodiment, the control device 18 can be a functional collection having functions such as an on-board inverter, a DCDC transformer, an MPPT (Maximum Power Point Tracking) controller, a HUB network assembly, and a convergence control box. It is understandable that the present application does not specifically limit the functions of the control device 18.

[0039] In one embodiment, the RV chassis assembly 100 is applied to a self-propelled RV, which may be a new energy RV 200. The control device 18 may control the battery device 20 to charge the power battery of the self-propelled RV, thereby increasing the cruising range of the self-propelled RV.

[0040] In one embodiment, the RV chassis assembly 100 is applied to a trailer RV, and the tractor of the trailer RV can be a new energy vehicle. When the trailer RV is connected to the tractor, the control device 18 can control the battery device 20 to charge the power battery of the tractor, thereby increasing the cruising range of the tractor.

[0041] In one embodiment, the control device 18 can control an external power source to charge the battery device 20. The external power source includes but is not limited to mains electricity and a solar panel 50. The solar panel 50 can be installed in the RV 200.

[0042] In some embodiments, the battery device 20 is detachably accommodated in the accommodation compartment 16 .

[0043] This facilitates assembly and disassembly of the battery device 20 and the control device 18 .

[0044] Specifically, when the battery device 20 requires maintenance or replacement, the battery device 20 can be removed from the chassis 12 and the maintained or replaced battery device 20 can be reinstalled into the storage compartment 16. Optionally, the control device 18 can be removably accommodated in the storage compartment 16. When the control device 18 requires maintenance or replacement, the control device 18 can be removed from the chassis 12 and the maintained or replaced control device 18 can be reinstalled into the storage compartment 16.

[0045] In one embodiment, the total number of battery devices 20 + control devices 18 initially loaded onto the chassis 12 may be less than the number of storage compartments 16. When the number of battery devices 20 is increased as needed later, new battery devices 20 may be loaded into idle storage compartments 16. The newly loaded battery devices 20 communicate with the control device 18 via the electrical connection mechanism 22, so that they can be installed and used immediately.

[0046] In one embodiment, the total number of battery devices 20 + control devices 18 initially installed on the chassis 12 may be less than or equal to the number of storage compartments 16. When the number of battery devices 20 is reduced as needed in the later stage, the battery devices 20 may be removed from the storage compartments 16 to reduce the weight of the RV chassis assembly 100, thereby reducing the weight of the RV 200 and improving the cruising range of the RV 200 or the tractor.

[0047] In the embodiment shown in FIG. 3 , the battery device 20 and the control device 18 can be detachably connected to the electrical connection mechanism 22 by plugging, so that the battery device 20 and the control device 18 can be detachably accommodated in the accommodation compartment 16 .

After the battery device 20 and the control device 18 are installed, the battery device 20 can establish communication with the control device 18 through the electrical connection mechanism 22. After the communication between the battery device 20 and the control device 18 is established, the control device 18 can control the battery device 20 to power the RV 200.

[0052] In one embodiment, the first connector 24 may include a plug, and the second connector 26 and the third connector 28 may include a socket.

If solar power is added during the day, the battery can be used for even longer, greatly reducing the charging frequency, supporting medium- and long-term travel and allowing you to focus on enjoying life.

[0087] 4. If the tractor is a new energy vehicle (such as a pure electric vehicle), the electricity stored in the trailer can also be output to the tractor to increase the driving range.
