The hybridization and electrification of military vehicles coupled with the desire to reduce fuel consumption has led to the need for an increase in power distribution controls including electronic circuit breakers (ECBs).The Department of Defense’s approach to tactical systems development and acquisition has aligned to a Modular Open Systems Approach (MOSA) strategy. Currently, no established form-factor standards exist to apply to power distribution to conform to MOSA. Intellisense proposed and chairs the VITA 85.108 Power Distribution and Controls Study Group to establish a common standard for ECB solutions to further commonality of the components, increase competition, and mitigate proprietary solutions. This paper describes the progress and activities to develop this standard.
