The invention discloses an electric valve and a thermal management system. A pressure sensing unit is included, the pressure sensing unit is connected with a valve seat, the pressure sensing unit can sense the pressure characteristic of a working medium in a detection flow channel and form a piezoelectric signal, an electric control part comprises an electric control board, and the piezoelectric signal forms an electric signal corresponding to the pressure through a conditioning circuit. The electric signal is used as a part for generating a signal for controlling the driving part, and the cost of the electric valve is reduced.
