DESCRIPTION

Automotive batteries for electric vehicles.

Object of the invention

In the system proposed the batteries will be attached to the electric vehicles, and will be easily separable, allowing the replacement of them, simply and quickly, so that the autonomy of the vehicles does not have technical limits in practice, with special application to public transport buses.

Background of the invention

In all cars and electric traction buses the automotive batteries are not changed until they have ended their useful life cycle and can no longer be recharged efficiently, an event that occurs after several years of operation.

In addition, it is intended that the autonomy of such vehicles be as large as possible and the weight of the batteries as small as possible and in this regard there are many projects for the development of new more efficient batteries, some with millionaire budget allocations.

Most experts predict that when the batteries reach autonomy levels close to one thousand kilometers, the explosion-engine cars have the days counted, because the electric traction is not polluting, and the cost per unit of distance traveled is almost one tenth of the conventional cost.

For this purpose, almost all of the automotive car and bus batteries used are called "lithium ion", batteries that provide greater autonomy to vehicles and have a moderate weight. In return, these types of batteries reach high prices in the market due to the high cost of their components and the complexity of their manufacture.

In order to reduce the center of gravity of the vehicles, the batteries are located at the bottom of the vehicles and well protected, to avoid deterioration due to the influence of external agents. Consequently the replacement of batteries, which is only done at the end of its useful life, is very laborious to perform.

With the current system, fully electric cars carry out their function until the batteries have discharged almost all of their charge. If you want to continue the service, the driver, in the case of public transport buses, has to change buses or wait for the bus batteries to be recharged, work that requires, in any case, a considerable time, which requires , to provide a good service to have a very large bus fleet.

Such circumstances make it difficult, or prevent the adoption of the electric public transport system due to the large investment required. Consequently, the adoption of the electric system in public transport is currently merely testimonial at European and world level.

Description of the invention

In the system that we propose the batteries will be attached to the vehicles and will be easily separable, allowing the replacement of them, simply and quickly.

The replacement of the batteries can be done manually, when the elements that make up the batteries are separated and the weight of each element does not exceed twenty kilos or automatically or semi-automatically when they are joined, because of their greater weight.

When the system is not manual, it can be carried out by means of hook, magnetic or vacuum cup cranes, or by means of conveyor belts, which will allow the continuity of the service without changing buses, simply changing the batteries quickly and easily.

The capacity of the batteries can be accommodated at the distances of the periodic routes that are made in public transport and consequently the batteries can be of moderate capacity, equipped with few elements, made with cheaper materials and consequently very low cost and of very reduced weight.

The current state of the art allows very moderate times for recharging the batteries and consequently only one additional battery per vehicle will be required. A battery will be in the utilization phase housed in the vehicle, and the additional one will be recharged in the place destined for replacement.

Description of the drawings

1) Box carrying the batteries.

2) Compartment of the electric traction vehicle for housing the batteries.

3) Electric traction vehicle.

4) Plug for recharging the batteries.

5) External terminals.

6) Connection of the external terminals with the electric system of the vehicle.

7) Hitch arch.

8) Flat part of the carrier box, partly metallic to enable its manipulation with vacuum suction cups or magnetic cranes.

9) Conveyor belt to facilitate the replacement of the batteries.

Preferred realization of the invention

The automotive battery, of moderate capacity and low cost, will be housed, in the event that their elements are attached, for their protection and easy handling, in a box (1), preferably of plastic material, in order to avoid weight, which in turn, in a compartment, preferably plastic, attached (2) in vehicles (3),

preferably in its rear and lower part or located in the lower rear part thereof.

The battery terminals will be connected to a plug (4) located in the said box, 5 to facilitate recharging, and to external terminals (5) so that when the battery carrier box is housed in the compartment attached outside the vehicle , said external terminals of the battery carrier box are connected to the electrical system of said vehicle (6).

10 The carrying case of the batteries, to facilitate its extraction, will be equipped with a small bow (7) in its upper part to be able to be hooked by the crane hook or hoist.

Additionally, the carrier box in its upper part (8) will be flat and, if necessary, in metal part, to facilitate its removal from the vehicle's container by means of vacuum cups or to be extracted by electro-magnetic cranes.

For its greater simplicity we accompany drawings of the preferred realization by means of a conveyor belt (9), for its best location in relation to the vehicle, to effect the change, they will be equipped with wheels.
