Problems solved by technology

[0005] Since the range extender is usually only used at maximum power, the base model is inefficient (as opposed to the most efficient case), it does not take into account the optimum time for the range extender to be used (only SOC is considered), and the battery pack is will end with a residual charge (partly generated by the range extender) that could have been used during the discharge process
Inherently, the aforementioned unused power generated by the range extender will be more expensive than plugged-in power from the grid

Embodiment Construction

[0062] figure 1 A range-extended electric vehicle 100 is schematically shown in . The vehicle includes means for activating a range extender 104 within an electric vehicle 100 in the form of a controller 102 connected to and in communication with the range extender 104 and a battery 106, which typically In the form of a battery pack. The range extender 104 is a secondary power source connected to a generator, such as a diesel internal combustion engine or a hydrogen fuel cell. The range extender is connected to the battery so that the battery is recharged by means of a generator (the generator circuit necessary here has been omitted from the drawing for clarity). The range extender 104 (via a generator) can also directly power the electric motor 108 , which is only done in certain circumstances described in more detail below.

[0063] The operation of internal combustion engines produces a variety of emissions, including undesired emissions that may be harmful to the envir...

Abstract

A method for controlling a range extender of an electric vehicle includes dynamically using actual measured or modeled pollution levels to set a target state-of-charge level for the electric vehicle range extender at a particular location.

Description

technical field [0001] The present invention relates to a device and a method for controlling a range extender of an electric vehicle and to an associated computer program. Background technique [0002] Electric vehicles come in various forms, namely pure electric vehicles (where the power source is only the battery), parallel hybrid vehicles (where the internal combustion engine or battery drive the wheels), or where a secondary power source (range extender) recharges the on-board battery Series hybrid vehicles. The present invention is primarily concerned with the latter. [0003] exist image 3 A known scheme for operating a vehicle with a range-extending function (called the "base model") is shown in . Using this scheme, the vehicle operates as an electric vehicle only until a predetermined charge level is reached, at which point the range extender is turned on, and will continue to be kept on until an upper state-of-charge (SOC) level is reached. [0004] In this bas...
