Abstract

See full text

A device, battery and method for spark detection based on transient currents is provided. The battery includes: a cell; an interface; a first protection circuit and a second protection circuit. The first protection circuit comprises a first switch between the cell and the interface. The second protection circuit comprises a second switch between the cell and the interface. The first protection circuit is configured to: measure a load current on the cell; and open the first switch according to a first delay time based on the measurement of the load current. The second protection circuit is configured to: measure a transient current on the cell above the load current; and open the second switch according to a second delay time, lower than the first delay time, based on the measurement of the transient current.
