US Patent 11603739 Electric, battery-powered wireline systems

A wireline system includes an operations cabin with a plurality of electrical devices, and a winch that includes an electric winch motor operable to drive a drum to manipulate a wireline cable. A first engine and a first electric generator are each arranged within the operations cabin and generate electrical power, a second electric generator driven by a second engine via a power takeoff to generate electrical power, and an umbilical extends from the operations cabin to an external energy source to provide electrical power. A battery pack is arranged within the operations cabin and includes rechargeable batteries communicably coupled to the electric generators and the umbilical, wherein the battery pack solely provides electrical power to the electric winch motor and the electrical devices, and wherein the electric generators and the external energy source provide electrical power to recharge the rechargeable batteries.
