Definitions

  • This invention solves the standardization problems in battery replacement systems for the large-scale power supply of mobile technology, especially electric vehicles of different power classes.
  • Battery replacement systems for electrically powered handsets are well known, cordless screwdrivers, cell phones and laptops are usually supplied with a reusable and replaceable electric battery. The performance of these devices is small enough that the removable batteries can be easily handled manually. This is different for larger power devices.
  • the drive battery is not as in e.g. To change a cordless screwdriver with a few simple steps, because this is too big and too heavy. It is therefore common to leave the battery of an electric vehicle in all operating conditions, even during charging in the vehicle.
  • the performance requirements of a modern electric vehicle make it necessary, in addition to charging at private and public charging stations, to think about practicable battery replacement systems.
  • Battery replacement systems for electric vehicles are known from the prior art. DE 10 2007 032 210, DE 196 21 668 and US 59 98 963 describe devices in which the battery on the underside of a vehicle to be assembled and disassembled.
  • a disadvantage of the prior art is the fact that the battery must be replaced as a contiguous block. As a result, a special replaceable battery has to be provided for virtually every vehicle class. However, each type of replaceable battery must then also be stored in sufficient quantity by the change station, which results in an increased and costly storage requirement. The large inventories increase the amount of batteries not in use, which results in the fact that generally more batteries are manufactured than would be the case for a more efficient system. All in all Although the known battery replacement systems are fairly able to solve the mobile energy problem, they generate too great a cost and an excessive standardization effort.
  • the drive battery of an electric vehicle no longer exists as a block hanging together but from a plurality of so-called energy cells.
  • the term energy cell generally describes a mechanical body which is equipped with or consists of electrical energy storage elements.
  • the power cell if provided for storing electrical energy, also includes electrical contacts by means of which it can be charged and discharged.
  • the mechanical formation of the energy cells is preferably standardized, and repeats uniformly in large numbers.
  • the size and thus the energy content of a battery is determined by the number of energy cells that make up the battery.
  • a battery can be changed in terms of size and power in fine steps and adapted to the respective technical requirements.
  • the energy cells are received to form a battery in a container which is in the mobile technology or intended for this.
  • the energy cells in the container When the energy cells in the container are discharged, they can be replaced by charged energy cells.
  • the energy cells are movable in at least one spatial dimension. This means that the energy cells are fixed in the container during the normal operation of the mobile technology and are connected to the mobile technology energy system.
  • the energy cells must be mobile.
  • the mechanical fixing of the energy cells as provided for the electrical contacting of the energy cell operable devices which mechanically fix the energy cells in the container of the mobile technology as needed or mechanically free and which connect the energy cells electrically as needed with the on-board technology and solve. It is also possibly provided one and the same device for both tasks, namely to use mechanical setting or release and electrical connection and release.
  • the mechanical setting of the energy cells occurs, for example, through the boundary walls of the container itself, wherein for the mechanical release of the energy cells, e.g. a flap in the container is opened, or a wall of the same is removed (see first embodiment), or by mechanical components which are introduced by an operable device in the container or in the container in their position are changed (see second embodiment).
  • the electrical connection and disconnection of the energy cells with the on-board technology takes place, for example, individually or in groups on one or more movable components mounted electrical contacts, wherein the movable components for connecting or disconnecting the electrical connections brought by an actuatable device to the electrical contacts of the energy cells or be removed from these again.
  • movable components for connecting or disconnecting the electrical connections brought by an actuatable device to the electrical contacts of the energy cells or be removed from these again.
  • such a device will produce electrical contact with several energy cells simultaneously.
  • These electrical connections are made and solved by e.g. a component that is equipped with a plurality of electrical contacts for a plurality of cells is mechanically brought to this or removed.
  • the arrangement of the electrical contacts of said component is preferably based on the anticipated arrangement of the energy cells in the container.
  • devices for mechanically setting the energy cells can also be provided in this way. It is important that the above-mentioned devices are operable, meaning that they have the ability to generate and also release the mechanical and / or electrical connections to the energy cells by means of manual or automatic actuation.
  • loose amount here describes a number of energy cells that are handled together, wherein the individual energy cells of this quantity can change their relative position to one another with at least one degree of freedom, ie it is provided that, for example, the energy cells do not mechanically bond to one another and in principle, as long as this is not limited by the handling devices, can move freely against each other, much like the molecules of a liquid, but the energy cells may or may not touch each other, but mutual contact of the cells may be necessary
  • the energy cells are mechanically movably connected so that the amount of energy cells can be handled like a moving chain, which can be manually or mechanically set in motion by pulling or pushing ,
  • the container which receives the energy cells, there is at least one closable opening through which the energy cells are applied or discharged.
  • Such an opening may be smaller in cross-sectional area than the smallest area of a container wall.
  • the densest packing which is preferably brought about by the constriction of the space in the container.
  • alternative facilities such as certain shapes in the container (bulges and elevations) in which the energy cells arrive automatically or with mechanical help, are also provided.
  • the energy cells a have one-dimensional freedom of movement, these will arrange themselves in the mobile technology in a row.
  • the energy cells have a two-dimensional freedom of movement, they will arrange themselves in a way that is similar to a 2-dimensional crystal lattice.
  • the arrangement of the cells in the container is predictable according to their predetermined freedom of movement, so that devices for the generation of electrical connections to the energy cells can be provided at the corresponding locations in the mobile device or in the container. It is one of the above-mentioned actuatable devices.
  • the energy cells are mechanically fixed, and created the electrical contacts between on-board technology and energy cells. Then the mobile technology is ready for use again.
  • partitions of variable size which may optionally be filled individually and independently. This should also be done, for example, with sliding walls. But can also take place with alternative methods, such as with devices for individual demand-dependent fixing of individual energy cells or energy cell groups.
  • partitioning may include, for example, a space for a quantity of energy cells remaining in the vehicle and being charged at private and public charging stations, and a second space being filled with rented energy cells as needed by the energy supplier, for example when there are longer journeys .
  • Another advantage is that mechanically it is much easier to machine a larger number of smaller cells than a single contiguous block. Also can be regulated on the number of energy cells, the degree of filling of the container, so that the user of the mobile technology is not forced to be traveling with a always the same size battery. So he can adjust the battery size of his vehicle to his current range requirements and thus saves weight and energy.
  • the opening in the body of the device in question may turn out much smaller than was previously possible. This is an advantage in the design of bodies.
  • the exploitation of the gravitational acceleration for the replacement process has the additional advantage that neither in the electric vehicle nor in the replacement devices consuming drives for handling the energy cells must be provided, because the supply of potential energy in the high energy cells can be done centrally and automatically at the loading devices of the exchange stations.
  • the invention has advantages, because this can e.g. Advertise electric vehicles with long ranges, without having to deliver the correspondingly large and expensive battery immediately, because the small battery can be added on demand at a public exchange station. In this way, the purchase price for an electric vehicle is significantly reduced without having to forego a possible long range.

  • the handcart 23 is removed and the vehicle 25 can resume its operation.
  • the energy to move around the cells consists essentially of the level of energy that is mechanically supplied to the cells in the charging station. Because the discharged cells are removed in the exchange station from the trolley 23 and lifted mechanically for loading on a plane which is at least slightly higher than the upper level 19 of the trolley 23, so then all other movements of the cells for loading the trolley 23 and those of the replacement process can be handled without additional drive technology.

  • a large container 30 for energy cells is available between the front axle 28 and the rear axle 29 of a vehicle 25, but a rear entrance 22 in this container 30 is narrowed, for example, by the subframe 31 in the rear.

  • Fig. 8 shows how the two poles are arranged concentrically to each other, so that the cell can be accommodated in the container at any angle of its axis of rotation, while still ensuring a secure electrical contact to the electrical system.
  • the cells 15 are preferably not handled individually when changing, but moved as a quantity. In this case, the cells 15 contact each other on their cylindrical surfaces and push each other in a predetermined by the boundary surfaces of the exchange devices direction.

  • the container 30 between the axles is wider than the entry port 22, although it is so wide and high that at least one cell 15 fits through it.
  • the container 30 is designed in its shape and dimensions so that, narrowing it, the cells 15 in it automatically enter into a uniformly repeating arrangement.
  • the narrowing of the container 30 occurs, for example, mechanically with the aid of one or more slides 33, 34.
  • two slides 33, 34 which are displaceable along the x-axis are provided in the vehicle, of which one, namely the slide 34, which holds the owner cells 14 separates from the loan cells 15, is additionally foldable, if necessary, to release the owner cells 14, if, as in this example, only one, namely the rear opening, is available.
  • the displacement of the sliders 33, 34 regulates the size of the container 30, or the size of its partitions.
  • the replacement process is essentially the same as in the first example, except that here the cells 15 are mechanically pushed by means of the slides 33, 34, 35 or that rolling devices in the sliding planes of the container, the Exchange devices or the cells themselves actively participate in or facilitate the transport of the cells 15.
  • the vehicle 25 is parked and the landing gear in the height (Z-axis) locked.
  • the electrical connections of the cells to the on-board technology have to be released and the cells must be mechanically released.
  • the release of the electrical contacts is done with the aid of an actuatable device, which is described in more detail by way of example below with reference to FIGS. 8 to 10.
  • the cylindrical power cells (see FIG. 13) slide on their lower cylinder end surfaces 32.
  • the upper cylinder end surface is provided with two electrical contacts 12/13 (see FIG. 8). Since the cylindrical cells during the exchange process can rotate freely about its own axis 1 1, it is not determined in which angle of rotation they are electrically contacted in the container 6 and mechanically fixed.
  • Fig. 8 shows a cell 15 in plan view with two contacts 12/13, wherein a contact 12 is designed as a circle, and another is arranged as a ring 13 to the first. Had the cell 15 more contacts, these would also be performed as a ring.

If the opening 22 is closed, the cells are trapped by the narrowness of the room and can not move. When the opening is opened, the cells may shift and exit the container. But there are, as already mentioned above, other solutions provided.
  • a trolley 23 equipped with loaded cells 15 is suitably placed on the vehicle 25 if the vehicle has not already been parked on an automatic exchange device.
  • This handcart has two levels, as in the first example, where the discharged cells are picked up from one level and the charged cells are delivered to the vehicle in front of the other.
  • the sliders 33, 34 in the vehicle move toward the rear opening 22 and push the discharged cells 15 out of the vehicle 25.
  • the discharged cells 15 are picked up by the trolley 23 or by the automatic exchange device.
  • the lateral guide members 36 are adapted to the trolley 23 or the automatic changing device to the width of the rear opening 22 of the vehicle 25, possibly also the height of the plane of the trolley, which contains the charged cells, adjusted accordingly.
  • the slides 33, 34 in the vehicle drive back towards the front axle.
  • the loaded cells 15 are now pressed by the trolley 23 and the automatic exchange device in the vehicle 25. Then, the rear opening 22 of the vehicle 25 is closed. Possibly. another slide, not shown, behind the rear opening 22 moves into the container 30 and pushes the cells 15 further into the interior of the container 30. The container 30 narrows and the cells 15 are automatically located in the predetermined closest packing. This also corresponds to a mechanical fixing of the cells. By removing this slide, the cells are released again. The electrical contacts to the cells 14 u. 1 are produced in the vehicle 25 by the actuatable device and the vehicle is now ready for use again.
  • a corresponding displacement of the slide in the container 30 ensures a weight-favorable distribution of the battery mass in the vehicle.
  • the cells are optimized in shape.
  • the shape of the cells may, for example, be spherical or be like a 3-dimensionally symmetrical crystal, so that the cells automatically enter the densest package while narrowing the space.
  • Electrical contacts may now also take place between the cells to direct the energy to the limits of the container, where this is then taken up by further contacts and forwarded to the on-board technology.
  • the cells can move in three dimensions in the designated limited spaces. The movement of the cells is triggered by the change of the rooms or the spatial form or by movements on the space boundary surfaces.
