Xue Gaofei, Director of the Software Department at the Product R&D Center of Wanbang Digital Energy Co., Ltd., shared insights on the ECC energy router independently developed by StarCharge.
The ECC is the central nervous system of energy products and the core pipe device in the cloud-pipe-terminal architecture that connects the levels above and below — born to solve the problem of isolated energy grids.
Its security hardening and defense-in-depth technologies have obtained dual certification in China and the EU, and as of October 2023 the ECC had run more than 20,000 hours of fault-free testing.
Openness and integration are the philosophy of Wanbang Digital Energy. Guided by the principles of sharing, flexibility, and speed, Wanbang Digital Energy leverages the ECC to deliver industry features such as open interfaces, free configuration, and one-click cloud onboarding, devoting its full strength to developing the intelligent microgrid platform.
The ECC is the 'golden key' to managing watts with bits. Our product currently supports more than 100 combinatorial strategies built from 9 individual control functions. Powered by advanced algorithms and hardware platforms, it achieves device response within 300 ms and system response within 1 second, and, under the philosophy of software-defined hardware, achieves full-scenario coverage of intelligent microgrid control.
04 Cai Xianyi: Applications of Automatic Charging in Heavy-Duty Truck Energy Replenishment
The new energy transition of heavy-duty trucks faces the challenge of balancing efficient operations with rapid energy replenishment, while the operational experience during rapid replenishment is also drawing growing attention. Dr. Cai Xianyi, Chief Engineer of the Product Innovation Center at Wanbang Digital Energy Co., Ltd., proposed applying automatic charging and battery swapping to heavy-duty truck energy replenishment, creating the ultimate recharging tool for heavy-duty trucks.
Heavy-duty truck battery-swapping stations equipped with StarCharge's automatic battery-swapping system complete a full swap in under 5 minutes — as fast as refueling — and have effectively improved operational efficiency across multiple scenarios.
The high-protection automatic side-charging equipment for rail vehicles can work in harsh, high-pollution environments such as steel plants and mines, achieving unmanned operation. Meanwhile, the charging connection terminals can be used in parallel, with a single terminal delivering a maximum current of up to 400A.
The high-precision automatic charging robotic arm for passenger vehicles features a 6-degree-of-freedom cooperative system and carries high-precision cameras that accurately identify the coordinates and angles of charging ports on all kinds of vehicles. The robotic arm thus enables a fully automatic charging mode. In addition, the system offers the fastest connector insertion speed — as little as 37 seconds from start to insertion — greatly reducing the share of time spent charging.
