Two new vehicular power management systems
Revision, known for advanced integrated soldier systems (ballistic head protection and wearable power management solutions, showcase the company’s latest vehicular power management systems on booth #320. Two platform power solutions will be on display: the Nerv Centr SWatPack modular lithium-ion power cells that make up Revision’s SILENT WATCH Battery Pack (SWBP) and the Nerv Centr SWitchPack, an advanced lithium-ion 6T vehicle battery.
“Revision has been developing these solutions, focusing our efforts to design, engineer, test and certify them with the ultimate goal of reducing sound, weight, and thermal signature while boosting lifespan,” said Revision CEO Jonathan Blanshay. “These innovative vehicle power solutions are built in response to those actively seeking more reliable energy performance, longer runtimes, and superior signature concealment. In developing these energy solutions, and working with leading OEMs, we’ve put some of today’s highest-priority power shortfalls in the crosshairs.”
Revision’s SWBP is a modular lithium-ion power platform composed of up to 10 independent 28V, 160Ah modules (SWatPacks), plus a power manager (SMS). Revision can develop customised enclosures to house more or fewer SWatPacks, as needed, as well as to accommodate different attachment methods. Individual SWatPacks are made from seven high-end lithium polymer cells (rather than hundreds of smaller cells, typical of most current systems); fewer connection points means less potential for failure, thus greater reliability and lower lifetime maintenance costs. Each SWatPack can last up to 6,500 cycles (approximately 10 years), and multiple redundant safety measures have been incorporated. SWBP systems and individual SWatPack cells are available now for global forces.
Revision’s lithium-ion 6T (SWitchPack) engine starter battery—designed to be MIL-PRF-32565 compliant—mounts in vehicle crew compartments. In accordance with US military standards, the SWitchPack battery is designed to meet Type 1 safety standards, but to provide near-Type 3 capacity. SWitchPacks are made from 14 high-end lithium polymer cells, similarly reducing connection points and boosting reliability.
Revision has conducted comprehensive preliminary testing and validation of the li-ion 6T SwitchPack, and is currently engaged in Qualified Products List (QPL) qualification.
SWitchPack batteries are expected to be in production and available by mid-2019.
Across all these products, one of the chief features is signature concealment, reducing thermal and heat signatures when idle for sustained covert ground operations. This emphasis on stealth and remote operability offers a scaled-up take on Revision’s dismounted power management solutions.
Revision Military won a $20 million, multi-year contract in 2015 through General Dynamics Land Systems Canada to provide Energy Storage Systems to retrofit RECCE 6.0 LAV vehicles that will silently power on-board sensor suites. The Revision system, built around its NERV CENTR SWatPack scalable battery system, is capable of operating in a wide range of hot and cold temperatures and climatic conditions beyond the objective eight-hours of Silent Watch powering time. The Revision battery system provides more silent watch time than 30 standard 6T format AGM batteries at less than half the weight.
This fully customised, ballistic-protected solution optimizes energy storage with a plug-and-play modular solution that can be serviced in the field.
