Method and device for controlling electric balance of vehicle-mounted inverter and vehicle

Abstract

The embodiment of the invention provides a method and device for controlling electric balance of a vehicle-mounted inverter and a vehicle. The method comprises the steps that the residual electric quantity value of a vehicle-mounted storage battery and the power of a load connected with the vehicle-mounted inverter are detected in real time; determining whether a power supply balance mode needs to be triggered according to the residual electric quantity value and / or the power of the load; and under the condition that it is determined that the power supply balance mode needs to be triggered, the engine is controlled to operate according to the target idle speed so as to charge the vehicle-mounted storage battery. According to the method, the device and the vehicle provided by the embodiment of the invention, the engine is controlled to generate power at the corresponding idle speed according to the residual electric quantity of the vehicle-mounted storage battery and the load power of the electric appliance, so that the balance between power utilization and power supply of the vehicle-mounted inverter is realized, the energy waste is avoided, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of vehicles, and in particular, to a method for controlling the electrical balance of a vehicle-mounted inverter, a device for controlling the electrical balance of the vehicle-mounted inverter, and a vehicle. Background technique [0002] Current vehicles are generally equipped with on-board batteries to provide power for electrical appliances connected inside or outside the vehicle. The inverter is a converter that converts the DC power of the battery into a constant frequency and constant voltage or a frequency-modulated and voltage-regulated AC power. For fuel vehicles, in order to meet the power demand of various electrical appliances connected to the on-board inverter, the on-board inverter needs to first convert the DC power provided by the on-board battery, but when the remaining power of the battery is insufficient, it cannot be used. Appliances provide ample energy. [0003] The on-boar...

Problems solved by technology

For fuel vehicles, in order to meet the electricity demand of various electrical appliances connected to the on-board inverter, the on-board inverter needs to convert the DC power provided by the on-board battery first, but it cannot be used when the remaining power of the battery is insufficient. Appliances provide sufficient energy

[0003] The on-board batteries of fuel vehicles are used to supply power to electrical appliances. In different power consumption scenarios, there will inevitably be differences in the power supply conditions of the batteries on both sides of the on-board inverter and the power consumption of electrical appliances, which makes the energy storage status of the on-board batteries may not be accurate. Adapt to the demand for power supply in the current power consumption scenario
