Discharging method and system for hybrid vehicle

Abstract

The invention discloses a discharging method and system for a hybrid vehicle. The hybrid vehicle comprises a power battery, a two-way vehicular charger, a motor and an engine. The method comprises the following steps of: after receiving an external discharging request, detecting the own state of the power battery, and judging whether the own state satisfies a pre-set discharging condition or not; if so, controlling the two-way vehicular charger to convert direct current provided by the power battery into alternating current, and discharge to external equipment; and if not, controlling the engine to drive the motor to output direct current, so that charging to the power battery and discharging to the external equipment are carried out. Thereby, the hybrid vehicle can be continuously discharged externally; particularly, the hybrid vehicle also can be externally discharged when residual electricity is less; continuous electricity demands of users can be satisfied; and furthermore, high-power and high-efficiency discharging requirements can be satisfied through the power battery and the two-way vehicular charger.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method for discharging a hybrid electric vehicle and a discharge system for a hybrid electric vehicle. Background technique [0002] Vehicles in the related art can only be discharged through the socket inside the vehicle when discharging to the outside, and cannot be continuously discharged, thus failing to meet the continuous use needs of users. In addition, in the related art, the discharge power and discharge efficiency during external discharge are relatively small, only about 150W, which can only meet the use of small electrical equipment. Therefore, there is a need for improvement in related technologies. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a method for discharging a hybrid electric vehicle, whi...
