Abstract
A drive system includes a first electrical network configured to convert time-varying power to direct current (DC) power; a second electrical network configured to convert DC power to time-varying power; an energy storage apparatus electrically connected to the first electrical network and the second electrical network; an estimation circuit including: an isolation switch configured to isolate the energy storage apparatus from the second electrical network, a discharge control switch, and an electrical sensor configured to measure electrical data related to the energy storage apparatus; and a control system configured to estimate a remaining life of the energy storage apparatus based on data measured by the sensor while the capacitive network is isolated.
