Embodiment Construction

[0019] Illustrative examples of the invention will now be described with reference to the drawings, wherein like reference numerals refer to like elements. The examples described below are intended to help those skilled in the art to fully understand the present invention, and are intended to be illustrative rather than limiting. The diagrams of elements, components, modules, devices and equipment bodies in the figure are not drawn to scale, but only schematically show the relative relationship among these components, components, modules, devices and equipment bodies.

[0020] In the following example, an electric vehicle is used as a vehicle to illustrate the power distribution method and system for electric vehicles according to the present invention, but this is not intended to limit the power distribution method and system according to the example of the present invention to only electric vehicles. In automobiles, other vehicles powered by batteries can also adopt the powe...

Abstract

The invention provides a power allocation method and system for an electric transportation means. The power allocation method includes: a) acquiring an estimation parameter from a battery management system of the transportation means; b) estimating the available discharge power of a battery according to the acquired estimation parameter; c) determining the power to be allocated for each of a plurality of demand parts on the basis of the available discharge power and the power demands of the plurality of electric demand parts of the transportation means; and d) outputting the allocated power tothe electric demand parts, and converting the output power into a torque to be outputted in a case that the power needs to be converted into the torque. A power allocation system is also provided.

Description

technical field [0001] The present invention relates to battery management of electric vehicles, and more particularly, to battery management and battery power distribution technology of electric vehicles. Background technique [0002] Electric vehicles effectively solve the problems of energy and environmental sustainability. The battery is the main energy storage system of electric vehicles, and its cost is also the main component of the cost of electric vehicles. At the same time, the development of batteries restricts the development of electric vehicles. [0003] More specifically, the main reason for the high battery cost is that current vehicle batteries have a short lifespan, and overcharging and overdischarging are the main factors affecting battery life. Contents of the invention [0004] In view of this, the present invention provides a power allocation method for an electric vehicle, which includes: a) obtaining parameters for estimation from a battery managem...
