Case study: Wireless battery charger
As robotic fleets reshape logistic, delivery and inspection industries the demand for more efficient and flexible charging solutions is increasing. At the same time more autonomy requires the elimination of human intervention. Targeted at aerial, mobile, marine and industrial robots this customer, WiBotic, wanted to develop a wireless charging station that avoided unreliable mechanical connectors and intelligently adjusted its output to meet the needs of different robots’ onboard batteries. The key goals were:
An external AC supply provided the nominal 48V power to the charging station. The voltage varied due to losses in the long cable, which a PRM buck-boost module then regulated. The output voltage and current of the PRM could be varied to match the wide range of battery types of the visiting robots. Key benefits were:
A PRM buck-boost module regulated the widely varying input voltages, providing a precisely regulated output, adjustable over a wide range to suit each robot’s battery requirement. To analyze this power chain go to the Vicor Whiteboard online tool.
