[0003] The disadvantage of such vehicles is that they have only a small range compared to vehicles with internal combustion engines and also cannot be quickly charged
Not only is this situation not very pleasant for the electric vehicle user, but it can also lead to an emergency situation or, if the user is already in an emergency situation, further aggravate the emergency situation

Embodiment Construction

[0030] exist figure 1 An electric vehicle 10 is shown in , which has an electric motor 12 and at least one energy storage unit 14 for storing electrical energy. A control system 16 controls the electric motor 12 and is coupled with the energy storage unit 14 . The accelerator lever is coupled to the control system 16 so that the control system 16 converts the signal of the accelerator lever into an energy outflow of the energy storage unit 14 .

[0031] In normal driving operation, however, the control system 16 prevents a further outflow of energy as soon as a certain predetermined residual capacity of the energy storage unit 14 is reached, for example 10%, that is to say until the energy storage unit 14 is completely emptied.

[0032] An energy transmission device 18 to be operated by the driver is coupled to the control system 16 .

[0033] There is one method by which the residual capacity of the energy storage unit 14 can be released. To this end, the use of the remain...

Abstract

The invention relates to a method for increasing the range of an electric vehicle (10), in particular an electric scooter, having an electric motor (12), at least one storage cell (14), and a controller (16) for the electric motor (12), comprising the following steps: a) initiation of the activation of a remaining capacity of the storage cell (14) by the operator, wherein the use of the remaining capacity is blocked by the controller (16) during normal driving operation, and b) unlocking the remaining capacity. The invention further relates to an electric vehicle (10), in particular an electric scooter, which can be operated according to the corresponding method.

Description

technical field [0001] The invention relates to an electric vehicle and a method for extending the range of the electric vehicle. Background technique [0002] Electric vehicles are known, in particular electric scooters, with electric motors supplied with energy from an energy storage unit, which are appreciated for their low emissions of harmful substances and noise. [0003] The disadvantage of such vehicles is that they have only a small range compared to vehicles with an internal combustion engine and also cannot be quickly charged. There is no home level (Rückfallebene) similar to that of a spare fuel tank in a vehicle with an internal combustion engine. [0004] Therefore, when the battery capacity is exhausted, the electric vehicle is forced to stop running. Not only is this situation not very pleasant for the electric vehicle user, but it can also lead to an emergency situation or, if the user is already in an emergency situation, further aggravate the emergency s...
