Rapid development in electric mobility raise distance anxiety. Thus, high ca-pacity systems with high efficiency are offered as a solution. However, the ca-pacity of the system is limited by the available space in the vehicle. To outcome this problem, the parallel distributed battery system is presented especially for heavy-duty vehicles like buses and trucks. Having a parallel distributed structure brings the necessity of providing a safety strategy not only for the single pack but also for the whole system. Every single pack has al-ready its fault protection system. Whenever an electrical fault occurs in the pack, it is cleared by either a contactor or a fuse. Thus, the pack becomes out of order, therefore, the vehicle cannot continue its operation and must be trailered. By utilizing a parallel dis-tributed battery system, vehicle continuity can be provided even after an electri-cal fault with a selective shut-off strategy. The presented strategy in this paper, not only provides vehicle continuity but also ensures additional safety on the system.
