Problems solved by technology

[0003] However, at present, a simple energy management strategy is used to distribute energy to the energy-consuming components of the vehicle, that is, when the supply capacity is insufficient, some high-voltage accessories are directly turned off. This simple energy management strategy can increase the driving speed of the vehicle. Mileage, but it will directly affect customer comfort and reduce customer satisfaction

Embodiment Construction

[0078] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0079] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0080] figure 1 It is a flowchart of a pure electric vehicle energy management method according to an embodiment of the present invention.

[0081] Such as figure 1 As shown, the pure electric vehicle energy management method of the embodiment of the present invention includes the following steps:

[0082]Step S1: Determine the energy supply mode of the vehicle system.

[0083] Step S2: If the energy required by the vehicle system is only provided by the power battery, that is, the power battery alone supplies the energy consumption of the vehicle system, the energy consumption of the energy-consuming components of the vehicle is ranked in order from high to low according to the prior...

Abstract

The invention provides an energy management method and system of pure electric vehicles. The method comprises following steps: determining energy supply mode of a vehicle system; if the energy of the vehicle system is only provided by power batteries, then energy is distributed on energy consuming components of the vehicle according to a first energy consumption priority sequence; if the energy of the vehicle system is provided by power batteries and motors, then energy is distributed on energy consuming components of the vehicle according to a second energy consumption priority sequence; if the energy of the vehicle system is only provided by motors, then energy is distributed on energy consuming components of the vehicle according to a third energy consumption priority sequence; if the vehicle is under the mode of slow charging, then the maximum charging power of a charging machine is controlled as a first preset power and the consumption power of air-conditioners is controlled as a second preset power; if the vehicle is under the mode of quick charging, then the maximum charging power of the charging machine is controlled as a third preset power. By means of the method and system of the invention, energy can be saved, driving range of the vehicle is increased and the vehicle comfort is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to an energy management method and system for pure electric vehicles. Background technique [0002] Pure electric vehicles use power batteries as the entire power source. Better power and longer cruising range are the main indicators to measure the performance of electric vehicles. However, they are limited by the current development of power battery technology, including cost, weight, Capacity and other issues, the rational use of energy has become a key research direction of pure electric vehicle technology, using limited energy to meet the greatest needs of customers. Pure electric vehicles use the power battery as energy to drive the power system assembly to drive the vehicle forward. At the same time, the power battery and low-voltage battery jointly supply other electrical components on the vehicle to meet the safety of the vehicle and the comfort of customers. The energy ...
