Abstract

See full text

A temperature estimation device includes: an initial value estimation unit that estimates an initial temperature value of an estimation target component at the start of operation of a power converter electrically connected to a power storage device; a variation estimation unit that estimates a temperature variation of the estimation target component based on the value of an electric current supplied from the power converter by the operation of the power converter; and a temperature estimation unit that calculates an estimated temperature of the estimation target component based on the initial temperature value and the temperature variation. The initial value estimation unit estimates the initial temperature value based on time elapsed between the previous issuance of a temperature estimation stop instruction for the estimation target component and the current issuance of a temperature estimation start instruction for the estimation target component.
