Description Battery powered systems are a major area of cyber physical system innovation. This paper develops a kinetic battery model with bounded capacity in the context of piecewise constant yet random charging and discharging. The resulting model enables a faithful time-dependent evaluation of the risk of a mission failure due to battery depletion. This is exemplified in a power dependability study of a nano satellite mission currently in orbit.
