Abstract

The invention belongs to the field of electrical equipment, and particularly relates to a temperature protection method and device of an electrombile and a motor controller of the electrombile. According to the temperature protection method and device of the motor controller, the temperature in the motor controller can be detected in real time, temperature signals can be timely converted into electrical signals to be input into an MCU, the MCU conducts analysis and judgment to obtain the current working temperature of the motor controller, the current value of a driving motor is changed based on the mapping relation between the current working temperature and the preset reference temperature value, accordingly, the heating quantity of internal components is controlled, then the temperature of the motor controller is stabilized, and the motor controller and the motor cannot be damaged by the over high temperature.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a temperature protection method and device for an electric vehicle and a motor controller thereof. Background technique [0002] At present, electric vehicles on the market do not use the temperature protection function. When driving for a long time in high temperature weather or under extremely heavy loads such as climbing, it is likely to cause damage to the power device in the motor controller due to excessive temperature or the electrolytic capacitor may be damaged due to temperature. If it is too high, it will burst, and the failure rate of the motor and controller will increase exponentially due to the high temperature. If the temperature of the key components of the controller or the motor can be detected in real time, and corresponding control strategies are adopted according to the temperature change, it is an effective way to improve the quality of the moto...
