Abstract

An over-temperature protection method (600) and apparatus (700), a device (800) and a storage medium for a solid-state circuit breaker. The method (600) includes: determining (610) a time constant indicative of an association between a temperature rise amount and an operating time of a solid-state circuit breaker operating at a predetermined operating current; determining (620) a first temperature rise amount based on a temperature rise amount detected before the solid-state circuit breaker is turned off, a duration for which the solid-state circuit breaker is turned off, and the time constant; determining (630) a second temperature rise amount based on the first temperature rise amount, the time constant, and an operating current detected after the solid-state circuit breaker is turned on; and controlling (640) a turn-on state of the solid-state circuit breaker based on a comparison between the second temperature rise amount and a predetermined threshold.
