With the acceleration of the construction of smart cities, smart parks, and smart mines, low-speed unmanned vehicles, as the fastest carrier for the implementation of L4-level autonomous driving, have seen a continuous expansion of their product categories and have formed large-scale fleets of various types. The industry standard T/SSITS 2006-2024 clearly states that low-speed unmanned vehicles specifically refer to electrically-driven unmanned vehicles with a speed of 30 km/h or less, operating in closed or semi-closed scenarios. The mainstream categories are divided into four core types:

1. Low-speed unmanned cleaning vehicles: small sweeping vehicles, medium-duty sweeping and cleaning vehicles, and disinfection and cleaning unmanned vehicles, used for cleaning in parks, municipal walkways, and factory road surfaces, where there is long-term exposure to rain and dust accumulation;

2. Unmanned logistics delivery vehicles: community delivery vehicles, factory material transfer vehicles, and supermarket retail unmanned vehicles, with frequent round trips and multi-vehicle cluster operations;

3. Security inspection unmanned vehicles: park security vehicles, photovoltaic power station vehicles, oil and gas plant vehicles, and factory patrol vehicles, operating 24/7 in outdoor environments;

4. Park connection sightseeing vehicles: small passenger shuttle vehicles for scenic spots, industrial parks, and airports, operating at high intensity during peak hours;

In addition, port low-speed transfer vehicles, photovoltaic cleaning unmanned vehicles, and low-speed livestock inspection vehicles also belong to the low-speed unmanned vehicle niche market.

According to the 2026 low-speed unmanned driving industry research, the total number of various low-speed unmanned vehicles in China exceeds 120,000 units, but over 80% of the fleets still use traditional metal plug contact charging. The charging process has become the core bottleneck restricting 7×24-hour unmanned operation. WIRELESSPT relies on a 180W-6000W full-power industrial wireless charging matrix, matching the voltage and power requirements of all types of low-speed unmanned vehicles. Relying on the official waterproof and explosion-proof specification books for standardized hardware, it solves the common outdoor charging pain points of multiple vehicle models in one step, and has been implemented in over 300 parks, cleaning, and industrial and mining customers.

1. Common charging pain points for all-category low-speed unmanned vehicles

1. Rapid interface wear-out in outdoor conditions

Unmanned vehicles for cleaning, inspection, and delivery are often parked outdoors for long periods. Rain, sand, dust, and corrosive fog continuously erode the metal plugs, causing oxidation and short circuits within 3 to 6 months; during rainy seasons, water accumulation in the interfaces极易 leads to leakage， presenting significant safety hazards. The annual expenditure on plug spare parts for each vehicle fleet exceeds 10，000 yuan.

2. Strict parking accuracy requirements， causing breaks in unmanned operation

Traditional charging requires precise alignment within ±3mm. The low chassis of low-speed vehicles， uneven ground， and debris on the road can easily cause positioning deviations. Autonomous parking often fails to complete charging， necessitating manual intervention to reset， completely disrupting the closed-loop unmanned operation.

3. Unable to achieve fragmented charging， resulting in low equipment utilization

Contact charging requires centralized visits to charging rooms for long-term static charging. Unmanned vehicles with depleted batteries during the journey can only stop and return， reducing the effective daily operation time of each vehicle by over 30%.

4. Poor compatibility for multiple vehicle models in the same area

When multiple low-speed unmanned vehicles such as cleaning， delivery， and inspection are deployed simultaneously in the park， the battery specifications (24V/48V/72V) are not uniform. Traditional charging stations cannot be universally used， and multiple sets of charging equipment need to be set up， resulting in large site occupation and cumbersome maintenance.

IV. Industry Development Trends and WIRELESSPT's Layout

At present, smart cities and digital transformation of industrial parks are accelerating across various regions. The deployment of multiple models of low-speed unmanned vehicles has become the norm. Unified, maintenance-free, and fully automatic wireless charging has become a basic requirement for infrastructure. WIRELESSPT, with its complete product line covering 180W to 6000W, can provide a one-stop solution for all low-speed unmanned vehicle categories including cleaning, delivery, inspection, and connection, addressing three core challenges: compatibility of charging for multiple vehicle models in mixed scenarios, durability in outdoor harsh environments, and full autonomous charging for unmanned vehicles.

Unlike single-power charging products on the market, WIRELESSPT has optimized a large-offset fault-tolerant design for low-speed unmanned vehicle chassis, ground unevenness, and mixed vehicle models scenarios. It does not require the installation of high-precision positioning modules, significantly reducing the overall vehicle modification cost. The annual production of 20,000 automated production lines can be delivered in batches.

In the future, WIRELESSPT will continue to improve the full-scenario energy solution for low-speed unmanned vehicles, helping parks, municipal services, and industrial and mining sectors achieve truly 7×24-hour zero-human operation for various low-speed unmanned vehicles, and promoting the commercialization and large-scale implementation of low-speed unmanned driving.
