Abstract

The invention provides a voltage stabilization control method and device of a battery voltage and electronic equipment. The method comprises the steps: obtaining the current voltage of a power battery, calculating the difference between the current voltage of the power battery and a preset reference voltage, and controlling the accelerator angle of a range extender based on the difference so that the working voltage of the power battery is stabilized within the preset range of the preset reference voltage. The accelerator angle can be adjusted through the current voltage of the power battery, and then the output power of the range extender is adjusted so that the working voltage of the power battery is stabilized near the preset reference voltage, the voltage stability of the power battery is ensured, and the service life of the power battery is prolonged.

Description

technical field [0001] The present invention relates to the field of power battery charge and discharge, and more specifically, relates to a power battery voltage stabilization control method, device and electronic equipment. Background technique [0002] The power battery installed on the electric vehicle can provide the power source for the vehicle, and the operating state of the power battery affects the working state of the vehicle and leads to insufficient mileage. In order to overcome the first two problems, a range extender is added to the electric vehicle. The range extender can not only directly provide the power source for the vehicle, but also charge the battery to extend the mileage of the vehicle. At present, the range extender is basically a constant power output, which will easily cause overcharging and overdischarging of the power battery during the charging and discharging process of the power battery, which will seriously affect the life of the power batter...
