Following the completion of the YUEDAO saltwater power generation project, the team initiated a new R&D initiative codenamed “RoboLite”—a next-generation energy terminal. Our goal was not to develop yet another portable power station, but to address a systemic redundancy in lightweight outdoor scenarios: users are often forced to carry separate lighting tools, energy storage units, and dry-cell battery chargers. This physical stacking consumes valuable space and introduces unnecessary efficiency losses through multiple energy conversions.
RoboLite is defined as an all-in-one modular energy terminal (DC 5–30V | 150W/Module | 300W MAX). Its core logic lies in decoupling electronic devices from their dedicated power modules/batteries, achieving objectives of lightweight design, extended lifespan, and environmental sustainability. Below are the key technological breakthroughs achieved during development:
1. Topology Design: Wide-Range Voltage Regulation in a Compact Form Factor
Pain Point: Traditional portable power supplies are limited by fixed-voltage outputs (e.g., 12V/10A), making them ill-suited for the discrete voltage requirements of field networking (Starlink Mini, soft routers), professional photography (15V cameras, 24V cinema lights), projectors (19V), and car refrigerators (12V/24V). Even when carrying high-capacity power stations, users must still lug bulky OEM AC-DC adapters.
Solution: RoboLite abandons the conventional “power supply + external voltage regulator module” approach. It integrates a proprietary Buck-Boost topology, delivering stable, continuously variable output from 5V to 30V within a form factor comparable to a standard power bank. This design eliminates intermediate conversion losses and failure points, significantly enhancing system reliability.
2. Structural Innovation: Magnetic Contacts and Parallel Expansion Mechanism
Pain Point: Conventional screw fasteners or mechanical latches hinder rapid assembly and add bulk. Furthermore, maintaining low contact resistance under high-current transmission (10A+), preventing arcing from vibration, and mitigating electromagnetic interference (EMI) from strong magnets pose substantial engineering challenges.
Solution: We adopted a Magnetic Snap-Fit design. Through precision structural optimization and multi-layer EMI shielding, we successfully minimized contact resistance and effectively suppressed vibration-induced arcing. This architecture supports arbitrary module stacking and parallel connection, completely resolving inter-module interference and enabling true “plug-and-play” scalability.
3. Thermal Coupling Management: Resolving Heat Conflicts Between Lighting and Power Systems
Pain Point: High-brightness spotlight modes and high-load DC-DC conversion circuits both generate significant heat. Simultaneous full-power operation creates thermal superposition, causing junction temperatures to spike rapidly and trigger abrupt shutdowns via overtemperature protection.
Solution: We developed a precise thermodynamic model at the firmware level, introducing an intelligent thermal-balance control algorithm. The system continuously monitors core temperatures and dynamically allocates power between discharge and lighting functions. This ensures stable operation under extreme conditions without risking damage from overheating—effectively eliminating unexpected power loss.
4. Integrated Energy Management: Cross-Module Hybrid Parallel Operation
Pain Point: Conventional power banks cannot charge one another or achieve seamless capacity/power expansion.
Solution: We designed a dedicated multi-channel energy management module to centrally coordinate each module’s Battery Management System (BMS). RoboLite supports not only inter-module charging but also seamless hybrid parallel operation with external sources such as the YUEDAO Portable Generator and solar panels. Users can enjoy expanded capacity and sustained high-power output without managing complex charging logic.
Scenario Definition & Market Insights
Our research indicates that over 95% of outdoor scenarios do not require kilowatt-scale power stations. Rather than mere capacity accumulation, wide voltage compatibility and physical flexibility are the keys to enhancing user experience.
RoboLite employs a “distributed carry, aggregated use” strategy:
- Lightweight: A single user carries only one ~150Wh module, drastically reducing load.
- Flexibility: In demanding situations, modules carried by multiple people can be instantly combined to scale up power and capacity.
- Cost-Effectiveness: Lowers initial purchase cost and avoids paying for redundant capacity.
RoboLite is more than a reimagining of portable power—it redefines the very logic of outdoor energy usage.
