摘要：
A traction battery arrangement includes a string of cells and bus bars, a coil wrapped around one of the bus bars, and a controller. The controller drives AC current over a swept range of frequencies into the one of the bus bars via the coil, and receives voltage data from at least one of the cells that results from the AC current.
