Description

"Earth-Powered Public Transit Vehicle with Optimized Architecture"

The present invention relates to a terrestrial public transport electric vehicle, of bus or tram-bus type, having an optimized architecture.

The field of the invention is the field of terrestrial public transport vehicles, of bus, bus or tram-bus type, provided with rechargeable electrical energy storage modules for supplying at least one electric motor of said electric vehicle.

State of the art

To reduce pollution in urban areas, the use of electric vehicles is booming, encouraged both by the awareness of users but also by administrative incentives to buy and use electric vehicles.

The development of terrestrial public transport electric vehicles raises the question of the positioning of the electrical energy storage modules intended to supply the electric motor of the vehicle as well as all the functional components involved in the operation of the electric vehicle, and in particular in the traction chain of the vehicle.

Currently, in the electric buses, the electrical energy storage modules and the functional units are arranged in a scattered manner in or on the bus. For example, the storage modules are, most often, arranged on the roof of the bus and the electrical components in different locations scattered in the bus.

Such an architecture is complex for the manufacture of the vehicle. In addition, access to electrical / electronic devices is made difficult by such an architecture, because of the scattered locations comprising these organs, which complicates the maintenance tasks of these organs. In addition, when the organs communicating together are distant from each other other, it increases the length of connectors / cables that connect them, and therefore the weight and cost of the vehicle.

An object of the present invention is to overcome these disadvantages. Another object of the invention is to propose a terrestrial electric public transport vehicle having a less complex architecture.

Another object of the invention is to propose a terrestrial public transport electric vehicle having an architecture facilitating access to the organs of said vehicle.

Finally, it is also an object of the invention to provide a terrestrial electric public transport vehicle in which the connection cost of the various electrical components is reduced.

Presentation of the invention

The invention makes it possible to achieve at least one of these aims by a terrestrial public transport electric vehicle comprising at least one electric motor for moving said vehicle and at least one rechargeable electric power storage module for supplying said minus an electric motor, characterized in that said vehicle comprises:

a housing, said rear, provided at the rear of said vehicle, preferably accessible from a rear face of said vehicle, for accommodating at least one rechargeable electric energy storage module; and

- At least one compartment, provided at the periphery of said rear housing, for accommodating at least one functional member.

Thus, the vehicle according to the invention proposes to have one or more functional members in one or more compartments arranged at the periphery of a rear housing in which rechargeable energy storage modules are arranged. Therefore, the organ or bodies are more easily accessible, for example to perform maintenance operations. Furthermore, the vehicle according to the invention makes it possible to have several functional units, and in particular electrical / electronic functional units, at the same zone in which there are also energy storage modules, so that the functional members and the electrical energy storage modules are arranged close to one another. Thus, the architecture of the vehicle according to the invention is simplified and the length of the electrical connectors used in the vehicle according to the invention is reduced. Therefore, the cost and space associated with these electrical connectors, as well as the time and labor for their installation are also diminished.

Advantageously, at least one compartment can be accessible from a rear face, in a longitudinal direction perpendicular to said rear face.

In particular, at least one compartment can be accessible from a rear face, in the direction of access to the rear housing.

Such a feature provides access to said compartment from a similar or identical area also allowing access to the rear housing, which is simpler for the operator.

Alternatively or additionally, at least one compartment may be accessible from a lateral face, in a transverse direction perpendicular to said lateral face.

In particular, at least one compartment may be accessible in a direction different from the direction of access to the rear housing.

Such a feature allows several operators to simultaneously intervene in said compartment and the rear housing, without interference, which allows greater flexibility during maintenance operations.

Advantageously, at least one compartment can be provided with an independent hood:

a cover of the rear housing accommodating at least one storage module, and / or - a cover of at least one other compartment.

Thus, when an intervention is necessary on the organ housed in this compartment, it is not necessary to discover the other organs or the storage modules of electrical energy, which reduces the risk of accidental damage to these other organs or modules for storing electrical energy.

In addition, such an architecture makes it possible to use hoods of smaller dimensions, which allows easier handling of the covers and the possibility of intervention in a confined environment.

Alternatively or additionally, at least one compartment may comprise a common cover with:

the rear housing accommodating at least one storage module, and / or

- at least one other compartment.

Thus, the architecture of the bus is simplified. In addition, the operator has faster access to multiple bodies by opening a single cover.

Such a second lower compartment may comprise at least one member, in particular an inverter, which is connected both to at least one electrical / electronic management member located in the first lateral compartment, and to at least one cooling member. located in the second side compartment. Having:

the electrical / electronic management members in a first lateral compartment provided on a first lateral side of the rear housing;

the cooling members in a second lateral compartment provided on a second lateral side of the rear housing, opposite to the first lateral side;

allows to isolate the cooling organs of the electrical / electronic management organs, while optimizing the connections of these organs with other vehicle components such as inverters, electric motors, etc.

Thus, the invention makes it possible to provide a more secure arrangement of the various members while optimizing the connection cost of these members as well as the length of the connectors used.

According to a particular arrangement, but in no way limiting, the first lower compartment is disposed between the rear housing and the at least one second lower compartment.

The vehicle according to the invention may advantageously comprise at least one firewall, or fire retardant, disposed between at least one, in particular each compartment and the rear housing. According to an exemplary embodiment, the rear housing may comprise four rechargeable electrical energy storage modules.

In an advantageous version, the rear housing and compartments may be arranged in a frame module forming the rear wall of the frame of said vehicle. Such a rear frame module may be independent of the rest of the vehicle frame, and may be assembled with the rest of the vehicle frame, by screwing, welding or bolting, etc.

Alternatively, the rear housing can be arranged in the vehicle frame, particularly in the rear wall.

Advantageously, at least one, in particular each, storage module disposed in the rear housing can be accessible in a direction perpendicular to the rear face of said vehicle.

Such access makes it possible to facilitate the maintenance operations of said storage modules and makes it possible to use simple and existing tools, such as a pallet truck or forklift, to dispose a storage module in the rear housing or to remove a storage module out of the storage compartment. rear housing. In a particularly preferred version of the vehicle according to the invention, the rear housing may comprise at least one rack, in particular several racks aligned in a vertical direction, and adapted to each accommodate a storage module.
