Description

The present invention relates to a device for managing the electric motorization means of an electric assistance vehicle. The invention also relates to an electric assistance vehicle equipped with such a management device. The invention relates to the field of the manufacture of electric assistance vehicles, more particularly the field of manufacturing management devices, which are intended to equip such an electric assistance vehicle, and which are designed to ensure the management of the means of electric motorization that includes such an electric assistance vehicle. Already known, such electric assistance vehicles that can take the form of a cycle, a motorcycle, a scooter or the like.

In particular, electric assistance vehicles are known which take the form of a cycle, more particularly a bicycle, especially an all-terrain bike usually called mountain bike.

Such an electric-assisted vehicle reinforces, on the one hand, means for storing electrical energy, on the other hand, electric motorization means powered by electrical energy by these storage means and, secondly, means for managing these electric motorization means.

In fact, these management means are designed to manage these means of electric motorization, so that the electric assistance vehicle complies with the legislation in force. In particular, these management means are designed so that, when the vehicle is electrically assisted in a public space, the electric drive means have a maximum power lower than a determined value (typically 250 Watts) and / or the electric-assisted vehicle has a maximum speed below a determined speed (typically 25km / h).

In fact, such management means may comprise an electronic controller, embarked by the electric assistance vehicle, and designed to manage the power of the electrical drive means, more particularly the power of the electrical power supply supplied to these means of electric motorization by means of storage of electrical energy. These management means may also include sensors (internal to the engine or to the wheel and / or mounted on this wheel) for raising the speed and manage the electric motor means according to this speed.

It should be noted that the legislation in force concerns the use of electric vehicles only in public areas.

Outside of such a public space, the power and the speed are however also limited because of the presence of the aforementioned means of management. Such a limitation is not necessarily desirable, especially when it comes to crossing roads or paths with high altitude, especially mountain bike.

The desire or need for higher power has led manufacturers to offer higher power batteries. However, by equipping with such a battery an electric vehicle, the latter is no longer in compliance with the legislation and is no longer approved for use in a public area.

Alternatively or additionally, to increase the power, it is also possible to replace the electronic controller. By making such a replacement, the electric-assisted vehicle becomes, again, non-compliant with the legislation and is no longer approved for use in a public space.
