BAE Systems has received a contract to develop an onboard vehicle power management system for a US High Mobility Multipurpose Wheeled Vehicle (HMMWV) that will be evaluated by the US Marine Corps in the summer.

The system will more than triple the HMMWV’s electric power output to 30kW and provide exportable power to support facilities such as command centres and field hospitals. The contract award is part of the Marine Corps’ Onboard Vehicle Power programme, funded by the 2009 American Recovery and Reinvestment Act.

The system generates and manages power used on the vehicle and exported from it, eliminating the need for towed generators.

It also manages other electric systems such as water pumps, engine fans, power-steering pumps and air conditioning. Electrifying these traditionally belt-driven systems improves mobility by providing more horsepower to drive the vehicle, improving fuel economy and extending engine life.

BAE Systems’ onboard power management system is currently used on the US military’s Paladin Integrated Management vehicle.

The Marine Corps is evaluating systems from two suppliers and plans to award a contract for five to 10 additional systems later this year.
