Abstract

The invention provides a power control method and device and an electric drive vehicle. The power control method is applied to the electric drive vehicle and includes the steps that an available powerparameter sent by a battery management system of the vehicle is received; a basic need power parameter of an air conditioner of the vehicle is determined; the air conditioner is controlled accordingto the basic need power parameter; a first surplus power parameter is determined according to the available power parameter and the basic need power parameter; a dynamic power parameter required by amotor of the vehicle is determined; and the motor is controlled according to the first surplus power parameter and the dynamic power parameter. By the adoption of the power control method, on the basis that the basic temperature need of a driver is met, the dynamic need of the vehicle can be met to the maximum degree, and in other words, the comfort of the driver and the dynamic property of the vehicle are considered.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a power control method and device and an electric drive vehicle. Background technique [0002] During the driving process, the power consumed by the high-voltage components (mainly the motor and the air conditioner) on the electric drive vehicle comes from the battery pack; the power consumption of the motor is due to the driver's demand for the power of the vehicle, and the accelerator pedal is expected to accelerate the vehicle. ; The power consumption of the air conditioner is due to the driver's demand for the comfort of the vehicle. By rotating the cooling / heating knob, it reflects the driver's desire for cooling / heating in the car; During special working conditions such as acceleration or heavy load climbing, how to control the output of the available power of the battery pack between the air conditioner and the motor is one of the issues that must be considered for electric drive v...
