ResGreen Launches Wireless Charging for Mobile Robot Fleets


August 10, 2022

ResGreen Group International, which develops next-generation mobile robots and software, has announced it is now offering wireless battery charging for its fleet of automatic guided vehicles (AGVs) and autonomous mobile robots (AMRs). The wireless charging capability allows vehicles to power up efficiently without requiring building modifications, such as cutting into a floor to install dedicated electrical lines.

ResGreen added that one wireless station can charge several vehicles with different batteries that require unique voltages and charge rates.

“Wireless charging is a game-changer for mobile robots in the material handling industry and will make an immediate impact on customers looking for ultimate flexibility and reliability,” said Parsh Patel, CEO of ResGreen. “The wireless charging stations are integrated with our BotWay software to provide robust remote monitoring, precise power management and detailed analytics for our customers.”

ResGreen said each wireless battery charging system includes a transmitter circuit and an onboard charger circuit. Similar to how smartphones recharge wirelessly, the transmitter circuit converts power from an electrical socket into wireless power, and sends it to a ResGreen PullBuddy AGV or LilBuddy AMR. The onboard charger, which is attached to the mobile robot, converts the wireless power to the correct DC voltage for that particular vehicle.

The company added that traditional opportunity chargers often require automated vehicles to connect directly to contacting plates, which can become ineffective without proper maintenance because of debris and dust covering the surfaces, as well as normal wear and tear. For the wireless charging task, the mobile robot needs to be within three inches of the transmitter circuit, and does not require physical contact, ResGreen said.

The wireless charging stations are also integrated with the company’s BotWay software system, which provides real-time monitoring and control features. Metrics about charging rates, battery life, battery temperature and more are available through the software.
