Electric vehicle control method and electric vehicle control device

Abstract

The invention discloses an electric vehicle controlling method. The electric vehicle controlling method is applicable to an electric vehicle controlling system. The electric vehicle controlling systemcomprises a power battery and a buffering battery. The controlling method comprises the steps of determining a current working mode of the power battery; when the current working mode of the power battery is an energy supplying mode, judging whether or not the buffering battery is in a full-electricity state, if not, controlling the power battery to charge the buffering battery in an optimal discharging mode, and on the condition that electric energy is stored in the buffering battery, controlling the buffering battery to provide electric energy for the outside; when the current working modeof the power battery is an energy-storage mode, judging whether the buffering battery is connected with an external power source or not, if yes, charging the buffering battery through the external power source, and on the condition that the electric energy is stored in the buffering battery, controlling the buffering battery to charge the power battery in an optimal charging mode. The invention further discloses an electric vehicle controlling device.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to an electric automobile control method and an electric automobile control device. Background technique [0002] In modern society, electrical equipment mainly obtains electrical energy from the country's main power grid. In the actual application process, the utilization efficiency of the current power grid is not high, which is mainly reflected in two aspects, one is the cost of power generation, and the other is the operating cost of regulating the voltage and frequency of the power grid. Due to the temporality and regionality of power consumption, when the power consumption demand exceeds the power generation capacity of the base-load power plant, the peak-shaving power plant will be put into operation because the grid itself does not have enough power storage. And when grid demand is low, electricity consumption falls below the output of baseload power plants, and any electr...
