COMBATT: Li-Ion Vehicle Batteries for The Longest Silent Watch Missions
Modern combat vehicles operate numerous onboard electronic systems that require extensive continuous electric power. Manned and unmanned turrets, missile launchers, radars and active protection systems, jammers, C3 systems, situational awareness, air conditioning, and other power consumers became integral parts of todays armored vehicles. This high energy demand applies not only when vehicle is on the move or during its short stops, but also during stationary missions often called “silent-watch”.
Supplying the vehicle with sufficient energy and high power rates during silent-watch is especially important in asymmetric and urban warfare, at static positions, when vehicles face a wide range of threats, keeping their acoustic and thermal signature low and saving fuel for later maneuvering.
Epsilor’s COMBATT line of Li-Ion vehicle batteries provides the highest energy density in the market, in two electro-chemistry technologies: Li-Ion NCA and Li-Ion LFP. Compliant with the US ARMY MIL-PRF-32525B safety and functional requirements, this line of batteries has been tested and selected by numerous leading defense vehicle manufacturers and users on 4 continents.
Independent BMS and Improved Safety
COMBATT 6T batteries are equipped with a smart internal BMS that enables vehicle users to smoothly integrate the battery into new and legacy vehicles with no special adjustments.
When installed onboard modern vehicles, COMBATT batteries activate various smart operating modes, that enable vehicle computers to closely monitor and control the battery optimizing its safety, durability, energy saving and life-cycle. Compliant with MIL-PRF-32565B of the US ARMY, the battery enables each user to activate these modes through a global standard interface. Alternatively, a user friendly CANBus communication protocol may be used to communicate with the battery.
In legacy vehicles, the BMS isolates the battery from vehicle computers protecting it from electrical anomalies, high voltage and high current surges, over heating and short circuit, providing it with a robust electronic safety envelope, as well as with a self charging management capability.
All Weather – All Environment Operation
Epsilor’s Li-Ion vehicle batteries support a wide range of operational temperatures, from -40°C (supported by rapid internal heating) and up to +71°, enabled by Epsilor’s smart high performance BMS.
In addition, Epsilor’s vehicle products are designed to perform and to survive harsh environments of tracked and wheeled military vehicles, ensuring long maintenance free operational life.
Long Operational Life Cycle and Reduced Life Cycle Cost
Designed to meet demanding operational use patterns, COMBATT Li-Ion batteries meet over 3,000 deep discharge cycles in the Li-Ion LFP configuration, and over 1,000 deep discharge cycles in the Li-Ion NCA configuration.
Epsilor’s field tests performed with the Israeli Defense Forces, as well as with other customers show that in a 5 year operational scenario, COMBATT batteries’ total cost of ownership will reach a break-even point with high quality lead-acid batteries, while storing 4 times more energy onboard.
