Abstract

The invention discloses a control method for discharging an electric vehicle. The control method comprises the steps of prejudging whether connecting state of the load and the electric vehicle satisfydischarging conditions or not; on the condition that the discharging conditions are satisfied, sending a discharging requesting instruction to a terminal to receive the discharging instruction of theterminal; detecting the power of the load, and according to the power of the load, calculating discharging parameters; sending the discharging parameters to a power battery pack to control the powerbattery pack to provide electric energy for the load. According to electric energy conditions actually needed by the load, the discharging parameters are set so that different loads can be subjected to power transmission, and the utilization rate of the electric energy of the electric vehicle is increased. The invention further discloses a control device for discharging the electric vehicle and awhole vehicle controller, and both the control device for discharging the electric vehicle and the whole vehicle controller have the advantages.

Description

technical field [0001] The invention relates to the field of electric power control, in particular to a control method, device and vehicle controller for electric vehicle discharge. Background technique [0002] With the vigorous development of the new energy automobile industry in recent years, the development and popularization of electric vehicles has important practical significance for alleviating the energy crisis and urban environmental pollution. Electric vehicles generally have a power battery, which is used to meet their own power consumption requirements such as driving the electric vehicle and running the air conditioner. The existing technology can also discharge the electric energy stored in the power battery to realize electric energy sharing between vehicles. The specific process is to send a discharge preparation command after receiving the trigger signal, and then detect whether the circuit meets the discharge conditions, and perform a discharge operation ...
