With the deepening of smart city construction, low-speed unmanned cleaning vehicles are moving from concept to the streets and alleys, becoming the tireless "silent cleaners" in urban management. They operate autonomously at night or when there is a sparse traffic flow, significantly improving cleaning efficiency and urban image. However, for these outdoor autonomous mobile robots to truly achieve "unmanned" operation, the last-mile challenge precisely lies in "energy autonomy" - the traditional charging method requires manual insertion and removal, which not only goes against the original intention of "unmanned" operation, but also faces many practical difficulties such as complex outdoor environment, easily damaged interfaces, and difficult management and scheduling. The "vitality" of unmanned cleaning vehicles urgently needs a more intelligent and resilient energy supply method.

Yuzheng Space Time focuses on outdoor complex working conditions and has launched a comprehensive solution for wireless charging of low-speed unmanned cleaning vehicles with all-weather, high intelligence, and no intervention. It is committed to becoming the "automatic energy supply station" for unmanned cleaning systems:

1. All-weather reliable power supply: Cleaning vehicles need to cope with extreme weather conditions such as rain, snow, high temperature, high humidity, and sandstorms. The wireless charging station and vehicle receiver of Yuzheng Space Time adopt integrated module design, achieving IP67 protection level, and passing rigorous environmental durability tests, ensuring long-term stable operation in outdoor environments ranging from -40°C to 60°C, truly achieving "uninterrupted" operation, and guaranteeing the continuity of urban cleaning operations.

2. High degree of freedom and convenient charging: For the possible positioning errors of cleaning vehicles when parking and positioning themselves, our system provides the industry-leading charging position freedom (supporting large offsets in the horizontal and vertical directions). The vehicle does not need centimeter-level precise positioning to start charging reliably, greatly reducing the positioning accuracy pressure and scheduling complexity of the autonomous driving system, and increasing the success rate of each charging task.

3. Efficient fast charging and intelligent scheduling: Equipped with Yuzheng Space Time's high-power wireless charging technology (such as 3kW/6kW solutions), cleaning vehicles can quickly replenish a large amount of energy during short breaks (such as dumping garbage, mid-task pauses). Combined with the cloud intelligent scheduling platform, the system can comprehensively monitor the fleet's power, task planning, and charging station status, dynamically assign vehicles to the optimal charging points for "fragmented" charging, achieving the optimal balance between fleet operations and energy replenishment, and maximizing the daily operation time of each vehicle.

4. Safety and long-term maintenance: Contactless charging completely eliminates the risk of leakage due to moisture and dirt in the outdoor environment and the spark hazards caused by manual insertion and removal. The non-physical wear charging method also significantly reduces maintenance costs caused by oxidation and damage to the charging interface, allowing unmanned cleaning fleets to maintain a relatively low total cost of ownership (TCO) over the long term.

This solution has been verified in multiple benchmark scenarios. For example, in a certain technology park in Shenzhen, several unmanned cleaning vehicles deployed with Yuzheng Space Time's wireless charging system achieved fully autonomous "operation-charging" cycles. After completing the cleaning of the area, the vehicles automatically returned to the designated station for charging, and after being fully charged, continued to perform tasks. The park achieved 365 days x 24 hours of cleaning coverage for the first time. In areas with high requirements for image and efficiency such as the Beijing Winter Olympics and Shanghai Pudong International Airport, similar unmanned cleaning wireless charging solutions have also been successfully applied, reducing the reliance on human resources, improving response speed, and avoiding visual interference from charging facilities to the public environment, earning high recognition from the management authorities.

Unmanned cleaning vehicles are the "nerve endings" of smart city management, and their wireless charging system is the "capillary network" that maintains the vitality of these urban "cleaners". Yuzheng Space Time is using its industrial-grade wireless charging technology that has been refined over ten years to inject lasting vitality that is not constrained by the environment and does not require human supervision into these urban "cleaners". We believe that when every sanitation vehicle can effortlessly obtain energy just as if it had an "instinct", a cleaner, smarter and more low-carbon urban future will eventually arrive as expected.
