Abstract

The invention relates to an energy control system and an energy control method for an electric vehicle. The energy control system comprises an accelerator pedal device, a motor, a battery status detection device and an energy management controller. The accelerator pedal device provides accelerator signals according to positions of an accelerator pedal, electricity provided by a battery serves as a power source of the motor, the battery status detection device provides charge information of the power battery and indicates second status information of power battery status abnormal levels, and the energy management controller judges current charge region where the power battery is positioned according to charge information and sets an operating mode of the motor according to the current charge region where the power battery is positioned, the second status information and the accelerator signals. Information of various statuses of the power battery and the accelerator signals are factors to be considered for operation control of the motor, faults are classified and graded to serve as references for operation control of the motor, and thereby operational reliability and safety and endurance of the electric vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to an energy control system and an energy control method of the electric vehicle. Background technique [0002] Electric vehicles mainly include pure electric vehicles, fuel cell vehicles, and hybrid vehicles. Pure electric vehicles use energy-storage power batteries as the only energy source, and use electric motors to drive vehicles, with characteristics such as zero emissions and low noise. But at this stage, the energy storage power battery as an energy source has low specific energy and specific power, which affects the battery life of pure electric vehicles. The discharge power of the battery will extend the driving range of the vehicle to a certain extent. [0003] Currently, many electric vehicle motors run at full power throughout the vehicle's entire operation. In this case, because the motor operation mode does not match the battery and the vehicle ope...
