Electric vehicle locked-rotor heat management system and method

According to the locked-rotor heat management system and method for the electric automobile, a function table database is used as a reference, signal collection is obtained through multiple paths, collection and processing of automobile tire air pressure, wheel temperature, driving motor temperature, motor controller temperature, ramp angle, motor three-phase current, high-voltage direct-current bus voltage and the like are achieved, PACK is structurally recombined, and the stability of the system is improved. An independent water tank is formed in the PACK, cooling circulation control can be achieved through software control, and temperature rise is reduced and torque is protected from being reduced by controlling and increasing the flow of a cooling system, changing a water channel circulation path and controlling air conditioner refrigeration and carrier frequency control. And table look-up control torque output is realized on static and dynamic torques and ramp and load functions through road spectrum acq
