Application: Electric working machine (Patent ID: US20230322124A1)
The patent filed by Kubota Corp describes an electric working machine that includes battery packs, a working device driven by electric power from the battery packs, battery monitors to monitor battery states, and a controller to manage charging and discharging. The controller selects a battery pack for discharging based on monitoring results in discharging mode and for charging based on monitoring results in charging mode.
The claims of the patent detail the specific functions of the electric working machine, such as selecting the battery pack with the highest remaining power level for discharging, switching to another pack when power decreases, selecting the pack with the lowest power level for charging, and switching when the charged pack reaches a certain threshold. The machine also monitors for abnormalities in the battery packs, determines charging or discharging mode based on external power supply connection, and includes switches for mode changeover and starting the machine based on battery pack monitoring results.
