In August 2021, the university signed an agreement with the Macao Water Supply Company Ltd. Based on this agreement, UM will provide wireless charging services for autonomous boats in local reservoirs, which will reduce labour costs by eliminating the manual operation of replacing batteries and using plug-in wired charging for the boats. This technology can also be applied to smart warehouses, where a dynamic wireless charging system can be installed on the ground to power warehouse robots around the clock, thus reducing the cost of manpower. Moreover, as the Macao Special Administrative Region government has been active in popularising electric vehicles, this technology can help to solve a dilemma facing the charging of these motorbikes — the diversity of charger types for different makes or models, as well as the high cost and safety hazards of the existing battery replacement cabinets in car parks. Formed by UM postgraduates from Macao, the research team for this project has founded a local company named Smarmac Technology Company Limited, which is specialised in designing and developing wireless charging systems and power electronics systems. The team hopes to commercialise this technology and apply it in different scenarios in Macao and other parts of the Greater Bay Area to contribute to the moderate economic diversification of Macao. There are currently around 320,000 warehouses in mainland China, but less than 20,000 of them are considered smart warehouses. Lam Chi Seng, head of the research team for the project, who is also an associate professor at the SKL-AMSV and the IME, says that the market potential for this technology is huge, adding that the dynamic wireless charging technology developed by his team can meet the needs of the smart warehouse market. ‘The greatest strength of our system is its high charging efficiency of up to 94 per cent, which is better than similar wireless charging products on the market. Even with a 20 per cent misalignment from the charging position, the high charging efficiency is still guaranteed.’ says Prof Lam. Macao has been striving to build a world-class smart city in recent years, with the goal of providing more high-quality services for its residents through smart basic infrastructures. Smart transport is one of the initiatives. The first step towards this development is to fully automate electric vehicle charging. ‘We can develop wireless charging receiver coil and circuit transmission pads for different makes or models of electric vehicles to achieve the most efficient wireless charging. When electric vehicles pass through the road paved with a wireless charging transmitter coil, they can be charged immediately.’ says Prof Lam. The construction of a smart city is not completed without implementing efficient, convenient, and user-friendly power supplies. Prof Lam hopes that the wireless transmitter coils will be installed in front of traffic lights or zebra crossings to enable wireless charging services for electric vehicles whenever they pass by, so that they can travel further. 掃二維碼 觀看訪談片段 Scan the QR code to watch the interview 林智聲教授 Prof Lam Chi Seng 動態無線充電系統充電效率高達94% The dynamic wireless charging system reaches a charging efficiency of up to 94 per cent
