Problems solved by technology

However, in the prior art, only the connection state of the power battery system of a pure electric vehicle and the correlation between the connection state and the driving speed or charge level of the vehicle are usually studied, and the driving work of the hybrid vehicle is not involved. This is not conducive to the optimization of the working performance of the power battery system of hybrid vehicles under different driving conditions.

Abstract

The invention relates to a method for controlling a power battery system (100) for a hybrid vehicle, in particular a plug-in hybrid vehicle. Thepower battery system hasat least two battery subsystems (11, 12). The control method comprises at least the following steps: detecting a driving speed and a driving mode of the hybrid vehicle; adjusting the series-parallel connection state between the at least two battery subsystems (11, 12) as a function of the travel speed and the travel mode. The invention also relates to a corresponding computer program product and a corresponding power battery system. The polarization effect of the single cell can be weakened, and the heat increase of the single cell can be reduced.

Description

technical field [0001] The invention relates to a control method for a power battery system of a hybrid vehicle, especially a plug-in hybrid vehicle. Furthermore, the invention relates to a corresponding computer program product and a corresponding drive battery system for a hybrid vehicle. Background technique [0002] In recent years, with the increasingly prominent energy problems and environmental pollution, people are increasingly choosing new energy vehicles as travel tools. Among them, hybrid vehicles with two sets of drive systems, the engine and the electric motor, have both good power performance and responsiveness of the engine. Kuaihe motor has the advantages of no pollution and low noise, thereby achieving an optimal balance of speed performance and energy efficiency. [0003] The power battery is the core component of a hybrid vehicle, and its working performance affects the charging time, cruising range and power performance of the vehicle to a certain extent...
