Embodiment Construction

[0041]It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0042] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0043] The remaining battery power threshold set in the vehicle to switch from power consumption mode to power maintenance mode is an important parameter for mode switching. If the threshold of remaining battery power is set relatively high, the vehicle will not be able to use the battery energy to drive the vehicle well. Because in this case, the use time of the power retention mode is relatively long, the engine working time is relatively long, the fuel consumption increases, and the emission performance deteriorates. If the remaining battery power threshold is set relatively low, the power performance in power retention mode will be deteriorated. Therefore, when the user needs ...

Abstract

The present invention relates to the technical field of vehicles, and provides a battery energy management method and device for hybrid vehicles. The method includes: obtaining the historical cut-off remaining power value and the historical maximum power demand for the vehicle cycle; according to the historical cut-off The remaining power value predicts the next cut-off remaining power value; predicts the lower limit value of the remaining power threshold for switching from the power consumption mode to the power maintenance mode according to the historical maximum power demand; predicts the cut-off remaining power of the next time The larger of the power value and the lower limit value of the remaining power threshold is determined as the remaining power threshold for switching from the power consumption mode to the power maintenance mode next time; and the determined next time from the power consumption mode The remaining power threshold for switching to the power maintenance mode is sent to the hybrid vehicle. It makes the management of battery energy of hybrid vehicles more suitable for user needs.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a battery energy management method and device for hybrid vehicles. Background technique [0002] There are multiple power sources in a hybrid vehicle, so it involves how to better coordinate the working states of the multiple power sources. [0003] At present, there are two management modes for the battery energy in the battery energy management strategy of the hybrid vehicle, which are respectively: a power consumption mode and a power maintenance mode. When the remaining battery power is high, the power consumption mode is adopted. In the power consumption mode, the electric energy in the battery is consumed as much as possible to reduce vehicle emissions and improve fuel economy. When the remaining battery power drops to a threshold, the vehicle starts to execute the power maintenance mode to control the remaining battery power within a certain range. [0004] In the relat...
