Description

Technical Field

[0001] This utility model relates to the field of new energy commercial vehicle technology, specifically to an electric van truck. Background Technology

[0002] Vans play a vital role in urban logistics, frequently used to transport valuable, fragile, or insured goods. The driving range of electric vans is a key performance indicator for urban logistics vehicles. In recent years, to improve range, electric trucks have undergone significant optimization efforts, including improving energy consumption, increasing battery capacity, and enhancing energy recovery.

[0003] However, due to limitations in battery pack energy density and vehicle structure, most pure electric vans currently cannot match the driving range of similar gasoline vehicles (on a full tank of gas). Furthermore, in scenarios where the battery is low and no charging station is readily available, there are potential driving hazards. Additionally, excessive battery depletion significantly impacts battery health and severely affects battery lifespan. Utility Model Content

[0004] This application provides an electric van truck to at least solve the technical problems existing in the related art.

[0005] An electric van truck is provided, comprising: a cargo box and solar panels fixed to the outside of the cargo box.

[0006] As an optional implementation, there are multiple solar panels, which are fixed to different sides of the carriage.

[0007] As an optional implementation, the solar panels are provided on the top surface and both sides of the carriage, and the solar panels are arranged parallel to the top surface or sides of the carriage.

[0008] As an optional implementation, it also includes: a backup battery pack, housed within a fairing at the top of the cab.

[0009] As an optional implementation, the backup battery pack is connected to the solar panel, and both the backup battery pack and the solar panel are connected to the vehicle control system.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0023] like Figure 1 As shown, this application embodiment provides an electric van truck, including: a cargo box 2 and a solar panel 1 fixed to the outside of the cargo box 2.

[0024] Solar panels 1 are installed on the surface of the truck body 2 to supplement the electrical energy and increase the vehicle's driving range. Solar energy is a renewable energy source that ensures the electric truck always has a power supply, protecting the battery pack and related electrical components from damage due to power shortages.

[0025] As an optional implementation, there are multiple solar panels 1, which are fixed to different sides of the carriage 2.

[0026] Specifically, solar photovoltaic panels can be installed on the top and sides of carriage 2. Based on the standard size of carriage 2, the top area is about 8㎡ and the left and right side areas are about 8㎡. According to the existing polycrystalline solar panel 1 (size 1.636×0.992×0.35, output power 265w) on the market, a maximum of 5 panels can be placed, two on the top surface and two on one side. Since the other side is where the carriage 2 door is located, one panel is placed on the other side, with a total output power of 1.325kw.

[0027] As an optional implementation, the solar panels 1 are provided on the top surface and both sides of the carriage 2, and the solar panels 1 are arranged parallel to the top surface or sides of the carriage 2.

[0028] As an optional implementation, it also includes: a backup battery pack 3, which is disposed inside the fairing 4 at the top of the cab.

[0029] A spare battery pack 3 can be added inside the fairing 4 above the cab roof and fixed to the battery pack mounting bracket 5. The battery pack mounting bracket 5 is fixed to the top of the cab, and the battery capacity can be set to 20 kWh or more.

[0030] As an optional implementation, the backup battery pack 3 is connected to the solar panel 1, and the backup battery pack 3 and the solar panel 1 are respectively connected to the vehicle control system.

[0031] As an optional implementation, the backup battery pack 3 is configured to discharge when the main battery pack charge is lower than a preset value.

[0032] The backup battery pack 3 can be set to start discharging when the main battery pack is about to run out of power, for example, when it is below 5%, 10%, or 15%, and the maximum vehicle speed is limited to no more than 60 km / h, which can increase the driving range by at least 50 km / h. At the same time, if the backup battery pack's power is lower than a preset value, for example, below 5%, 10%, or 15%, the backup battery pack will stop discharging.

[0033] As an optional implementation, the solar panel 1 is configured to charge the backup battery.

[0034] As an optional implementation, the charging method of the backup battery pack 3 also includes charging when the vehicle is connected to the charging pile.

[0035] The backup battery pack 3 can be charged in three modes: During the day, when there is sufficient sunlight, it can be charged via solar panel 1. It can also be charged via a charging station. Alternatively, during energy recovery operations on long downhill sections, it can assist the main battery pack in recovering energy; when the main battery pack is fully charged, the recovered energy can be used to charge the backup battery pack 3.

[0036] As an optional implementation, the solar panel 1 is configured to charge the main battery pack.

[0037] As an optional implementation, it also includes: a battery pack mounting bracket 5 fixed to the top of the cab, and the spare battery pack 3 fixed to the battery pack mounting bracket 5.
