BAE Systems Controls has been selected by Lockheed Martin to develop the power management system for the Lockheed Martin Unmanned Ground Combat Vehicle, or UGCV.
The power management system incorporates BAE Systems’ HybriDrive, a hybrid-electric drive subsystem.
The HybriDrive will consist of 10 modular integrated motor controllers to manage the vehicle’s motor drives, a modular battery management system to provide fault-tolerant energy storage, a redundant permanent-magnet generator driven by a modified COTS diesel engine and a low-voltage bus power system for vehicle accessory and mission systems.
According to BAE Systems, the HybriDrive will provide the UGCV prototype with benefits including increased operating range compared to conventional diesel power, enabling the vehicle to operate 14-day missions on a single tank of fuel and abundant on-board power to conduct surveillance missions.
The HybriDrive will also allow the UGCV to be operated in a ‘silent drive’ mode for limited periods solely under electric power, with the engine off, to reduce the vehicle’s noise and heat signature.
Measuring approximately 6 feet long, 30 inches wide, and 18 inches tall, the UCGV will ride on six motor-driven wheels, each mounted on a 360-degree articulating arm to handle rugged terrain in a variety of reconnaissance, surveillance, and targeting missions.
The diesel-driven generator will provide electric power to the wheel and arm motors and will charge the energy storage system.
