Furthermore, the invention relates to a system with several of the aforementioned mobile containers, wherein a main control unit is provided, and to a system with several mobile containers, wherein each mobile container has its own control unit. Storage systems are known in the prior art in which batteries are inserted before being charged. US Patent 6,094,028 A, for example, discloses such a device. A disadvantage of this system is its complex design and its inflexibility for some applications. Further battery charging systems are known from US 6 498 457 B1, DE 10 2009 034 371 A1, DE 93 05 524 U1 and EP 2 088 012 A2. DE 20 2008 007 663 U1 also discloses a battery testing system. It is therefore an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to provide a device that offers a flexible way to store batteries that are at least partially discharged in a safe space and to recharge them on site. The foregoing problem is solved by a mobile container according to all features of the independent claim and by a system with all features of the associated independent claim. Further features and details of the invention will become apparent from the respective dependent claims, the description, and the drawings. Features and details described in connection with the claims of the invention naturally also apply in connection with the mobile container and the system according to the invention, and vice versa, so that the disclosure of the individual aspects of the invention is always, or can always be, mutually interdependent. The problem is solved in particular by a mobile container for charging, and especially storing, at least one battery. The battery can also be designed as an electrochemical energy storage device. The container has an enclosure that defines a cargo space and has a lockable loading hatch. A battery charging station is located in the cargo space, which includes a receptacle for an energy converter and a battery receptacle into which a battery can be inserted via the loading hatch. The energy converter can also be configured as a charger. The battery charging station ensures that both the energy converter and the battery are reliably positioned within the charging compartment. The charging compartment can be closed, for example, via a locking mechanism, so that when the container is closed, it is reliably protected from environmental influences such as moisture, dust, etc. The battery is a rechargeable battery or energy storage device, in particular an accumulator, which can be removed from the container by the user after a defined charging cycle. Preferably, the battery thus comprises an electrochemical energy storage device. The container according to the invention is a mobile container that can be individually positioned in different locations, in particular inside and / or outside a building, depending on the requirements.Advantageously, a frame can be provided that integrates the battery charging station with a mount for the energy converter and the batteries themselves. The frame can be made of metal, for example, and its dimensions can be individually adjusted to suit the geometry of the batteries to be charged and / or the energy converter. The frame can be attached to the inside of the enclosure, for instance, which improves the stability of the individual components. The invention also relates to a system comprising a mobile container according to the invention, wherein a main control unit is provided which communicates with at least one transmitting and / or receiving unit of each container or with a control unit of each container. An advantage of this system is that all containers can communicate with each other. The system according to the invention receives information, for example, the number of batteries present in the container. Furthermore, it is conceivable that the state of charge of each individual battery is also transmitted to the system. The main control unit can be positioned independently of the container, for example, in an external central unit, which could also be a data cloud. Alternatively, a mobile container can also serve as the central unit.It can also be useful for each mobile container to have its own control unit, with the individual control units communicating with each other via the transmitting and / or receiving units. Advantageously, the invention provides that the ventilation system is positioned and designed in the cargo space in such a way as to achieve cross-ventilation of the cargo space. The ventilation system is dimensioned appropriately for the battery charging concept used. This effectively ensures that the hydrogen level in the cargo space remains within the normal range. Any escaping gases, for example from the battery, can be effectively extracted by the ventilation system. Cross-ventilation has proven to be particularly effective in extracting harmful gases from the cargo space. According to the invention, the container has an elongated extension running along its base, with the cross-ventilation occurring essentially along the elongated extension of the container, particularly the cargo space. According to the invention, a ventilation system is provided to extract gases generated during the battery charging process from the cargo space. In particular, the ventilation system can have an exhaust air section and a supply air section, with at least the exhaust air section having a fan for active extraction. This also allows for cross-ventilation of the cargo space. It is particularly effective if the supply air section is positioned near the bottom of the container and the exhaust air section is located near the roof. Effective cross-ventilation can be achieved if the supply air section and the exhaust air section are located as far apart as possible within the enclosure. For example, the exhaust air section can be positioned diagonally to the supply air section within the enclosure. It is advantageous that, within the scope of the invention, a power supply system is arranged within the cargo space, which can be electrically connected to the energy converter. The power supply system offers high flexibility and cost-effectiveness, as it is easily accessible for other components within the enclosure, or the aforementioned components can be easily electrically connected to the power supply system. For example, it can be advantageous to position mains sockets near the energy converter, with the power supply system having integrated electrical supply lines that are advantageously expandable in a modular fashion. A further advantage is that the ventilation system includes a monitoring unit to check the airflow. The exhaust airflow is also monitored. If the airflow falls below a certain threshold, the power supply system is shut off, thus stopping the batteries from charging. Furthermore, the monitoring unit may be equipped with a sensor that shuts off the power supply system if the airflow falls below a certain threshold. This sensor could, for example, be a differential pressure sensor. It is possible that a gas monitoring unit is installed in the cargo hold to detect the explosive potential of a gas-air mixture within the cargo space, and specifically to de-energize the power supply system when a gas-air mixture limit is reached. In addition to the monitoring unit, the gas monitoring unit can be integrated into the container to monitor the gas-air mixture within the cargo hold. If a defined gas-air mixture limit is reached, the power supply system is de-energized for safety reasons, just as with the monitoring unit. This means that the battery charging process is interrupted. For example, the gas monitoring unit can measure the explosive limits of the gas-air mixture and, for instance, perform a defined action when the upper and / or lower explosive limit (UEL or LEL) is reached. Advantageously, the invention may provide that the enclosure has an alarm device to emit a visual and / or acoustic signal, in particular that the alarm device is in signal communication with the gas monitoring unit and / or the monitoring unit of the ventilation system. Advantageously, the user receives visual and / or acoustic feedback if irregularities occur during the battery charging process inside the container. The alarm device may additionally or alternatively also emit a signal that is receivable by an electronic unit and recognized as an alarm signal. A further advantage is that the battery holder has a support surface for the battery, which allows the battery to be moved translationally within the holder, in particular that the support surface has movably mounted transport elements. Advantageously, the support surface according to the invention offers the possibility of conveniently and quickly moving the battery into or out of the battery holder. Since batteries have a high weight in some applications, the support surface according to the invention is particularly advantageous for the translational movement of the battery. In one possible embodiment of the invention, several transport elements are arranged parallel to each other, which enable easy movement of the battery on the support surface or in the battery charging station. The transport element may be cylindrical. For example, the transport elements could be rollers onto which one or more batteries can be positioned. Translational movement of the battery on the support surface is conceivable in various directions. The ventilation system is advantageously in continuous operation. This increases the safety of the container. It is possible that the cargo space is equipped with an air conditioning unit, specifically designed to allow the temperature of the cargo space to be set between 5°C and 30°C. Advantageously, the air conditioning unit is designed to allow temperatures between 10°C and 25°C. This temperature control allows for the protection of electrical components located inside the container, particularly batteries and energy converters. Furthermore, the air conditioning unit can be designed to also allow for the adjustment of relative humidity within the enclosure, specifically achieving a humidity level of up to 95% at approximately 20°C to 25°C. Adjusting the relative humidity can also promote or slow down the aging process of electrical components within the enclosure, such as energy converters or batteries. Advantageously, the invention provides that a collection device is arranged below the battery holder to collect any medium that may leak from the battery and / or charger, in particular that the collection device is made of plastic. The collection device may have a cavity, in particular be designed as a tray. The battery holder has through-openings so that any medium that may leak from the battery, such as acid, can immediately enter the collection device. It can be advantageous if the invention includes a locking element for opening and closing the loading opening, particularly if the locking element is a sliding door, a roller door, or a hinged door. When the locking element is in the open position, free access to the battery(ies) in the cargo space is possible. Loading and unloading the container can be carried out, for example, using a motorized vehicle with a lifting device, such as a forklift-type vehicle and associated lifting gear. Alternatively, loading and unloading can be performed using special swapping devices in a translational motion. The large loading opening allows easy access to all batteries within the container. A further advantage is that the battery charging station has a base element on which the energy converter can be positioned, with the base element being arranged above the battery receptacle. The base element can, for example, be attached to a rear or side wall. In one possible embodiment, the base element is located approximately at mid-height within the charging compartment, thus ensuring a safe distance to the batteries positioned below. Furthermore, the energy supply system may include a rail element, in particular a conductor rail, wherein the rail element serves to supply the energy converter with electricity, and in particular, the base element is arranged between the rail element and the battery housing. The rail element may be extended according to the dimensions and geometry of the container, and electrical supply lines and sockets, in particular for individually connecting the energy converters, may be provided within the rail element. The cargo space may include a water refill station. The enclosure may have a mounting element onto which the water refill station can be positioned or attached. The water refill station can serve as a reservoir for the batteries. If a battery has insufficient water, it can be refilled manually or automatically via the water refill station. A detection unit located within the cargo space can monitor the battery's water level. The water refill station can be connected to a mains water supply to produce and store demineralized water for battery refills. Furthermore, it is advantageous if, within the scope of the invention, the battery charging station includes a safety element to protect a rear wall of the enclosure. The safety element can be arranged, for example, on a side wall, on the floor, or on the rear wall of the enclosure. Advantageously, the safety element is made of a metallic material. When the battery is inserted into the charging compartment and pushed into the battery holder and moved, the safety element prevents the battery from colliding with the rear wall or any of the walls of the enclosure. It is conceivable that the safety element is arranged at a distance from one of the walls of the enclosure. Within the scope of the invention, it is conceivable that a fire extinguishing device is provided within the cargo space, in particular that the extinguishing device is designed as a sprinkler system. It is conceivable that the extinguishing device is triggered in the event of extreme heat development within the cargo space. Additionally, the alarm can trigger a corresponding signal, in particular visual or audible. The extinguishing device is advantageously arranged on the ceiling of the enclosure. Advantageously, activation of the extinguishing device immediately disconnects the power supply system of all electrical components within the container, in particular the battery charging process. Furthermore, the invention may include a renewable energy system connected to the energy supply system and / or the energy converter, in particular, the renewable energy system being located on the roof of the enclosure. Advantageously, the integration of the renewable energy system can effectively support battery charging. The renewable energy system can also support the energy supply system. Excess energy generated by the renewable energy system can, of course, be fed back into the public grid. The renewable energy system could, for example, consist of photovoltaic cells. Furthermore, within the scope of the invention, it is conceivable that a display element is provided which indicates whether a battery is occupied or not and / or indicates the battery's state of charge. The display element can be a screen capable of showing all relevant information. Alternatively, the display element can be a color element capable of emitting different colors to indicate the occupancy status of the battery charging slot or the battery's state of charge, particularly before, during, or after charging. Alternatively, the display element can be located either inside the cargo space or outside the cargo space on the enclosure. The display element can be mounted externally on the roof or on the sides of the enclosure. It can also be positioned inside the cargo space, for example, on the floor, the frame, or the walls of the enclosure. Advantageously, a control unit can be provided that communicates with the power supply system and / or the ventilation system and / or the monitoring unit and / or the display element and / or the alarm device and / or the gas monitoring unit and / or the air conditioning unit and / or the fire extinguishing device and / or the renewable energy system. The control unit can be mounted on the wall of the enclosure or integrated into the energy converter. Within the scope of the invention, it may be provided that a transmitting and / or receiving unit is arranged on the enclosure, which is in signal communication, in particular, with the control unit and / or the power supply system and / or the ventilation system and / or the monitoring unit and / or the display element and / or the alarm device and / or the gas monitoring unit and / or the air conditioning unit and / or the extinguishing device and / or the renewable energy system. The transmitting and / or receiving unit may be integrated within a wall of the enclosure. It is also conceivable that the transmitting and / or receiving unit is positioned on the roof of the container. Furthermore, a large number of battery charging points are provided within the cargo space. This makes it possible to charge several batteries simultaneously in the container. Advantageously, each battery is electrically connected to its associated energy converter. According to the invention, the batteries are located on the battery tray and are spaced a defined distance apart. An additional aspect of the invention is a system comprising several mobile containers of the type according to the invention. This system includes a main control unit that communicates with at least one transmitting and / or receiving unit of each container or with the control unit of each container. Thus, the system of multiple containers according to the invention offers the same advantages as those described in detail for the single container according to the invention. Furthermore, access control may be provided, allowing only authorized personnel to enter the container. The container may have a locking system that controls and / or regulates access to the battery charging stations. This locking system may include a lock cylinder and / or a keypad and / or RFID, thereby enabling or preventing access. Further advantages, features, and details of the invention will become apparent from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description can each be essential to the invention individually or in any combination. The figures show: Fig. 1 a schematic representation of a mobile container according to the invention, Fig. 2 another representation of a container according to the invention, Fig. 3 another embodiment of a battery mount for a mobile container, Fig. 4 another schematic representation of a mobile container with a renewable energy system, and Fig. 5 a schematic view of a system according to the invention with several mobile containers. In the following figures, identical reference numerals are used for the same technical features even for different embodiments. The preceding explanation of the embodiments describes the present invention solely by way of examples. Naturally, individual features of the embodiments can be freely combined with one another, provided this is technically feasible, without departing from the scope of the present invention. Figures 1 and 2 show mobile containers 1, each with an enclosure 3, which defines a cargo space 4. The cargo space 4 has a lockable loading opening 5 via a locking element 7. Within the cargo space 4 is a battery charging station 10, comprising a receptacle 11 and a battery receptacle 13. An energy converter 12 can be positioned in the receptacle 11, and a battery 2, which is a rechargeable battery, is located in the battery receptacle 13. The battery 2 can be inserted into or removed from the container 1 via the loading opening 5. The battery 2 rests on a support surface 14 of the receptacle 11. The support surface 14 allows the battery 2 to be moved translationally within the battery receptacle 13, the direction of movement being indicated by the arrow in Figure 1.The support surface 14 can, for example, be formed by movable transport elements 15, which are shown in simplified form in Fig. 3. The transport elements 15 are, for example, rollers, in particular cylindrical ones, which enables reliable movement of the individual batteries 2 within the battery charging station 10. The battery holder 13 can also be equipped with ball bearings. Furthermore, the mobile container 1 has a ventilation system 20, which is shown in Fig. 2. During the charging process of the batteries 2, any gases that may be produced, for example, escaping from the batteries 2, are extracted from the cargo space 4. For example, it is conceivable that the ventilation system 20 is permanently in operation for safety reasons. For example, it is conceivable that the ventilation system 20 has an exhaust air section 21 and an intake air section 23, thereby achieving reliable cross-ventilation of the cargo space 4. Cross-ventilation ensures the satisfactory removal of any gases that may be produced within the cargo space 4. For example, the exhaust air area 21 can be equipped with a fan 22 for active extraction, as shown in Fig. 2. Positioning another fan in the supply air area 23 is also conceivable. As shown in Figures 1 and 2, the mobile container 1 has a power supply system 30 within the cargo space 4, enabling a reliable power supply for all electronic devices and equipment in or on the container 1. The power supply system 30 is designed with a rail system 31 that runs transversely along the longitudinal extent of the mobile container 1, with the rail element 31 positioned near the power converters 12. The power converters 12 are electrically connected to the rail element 31. The power supply system 30 can also include sockets for the electrical connection of the power converters 12. The ventilation system 20 has a monitoring unit 24 that checks the airflow in the ventilation system 20. If the monitoring unit 24 detects that the airflow has fallen below a limit value, the power supply system 30 is switched off for safety reasons; in particular, the batteries 2 are no longer charged. A corresponding alarm signal can be emitted via an alarm device 35, which can be visual and / or audible, for example. It is conceivable that a gas monitoring unit 40 is placed in the cargo compartment 4 to detect an explosion of the gas-air mixture within the cargo compartment 4. If the gas-air mixture reaches a limit value, the power supply system 30 is also switched off, in particular, charging of the batteries via the energy converters is stopped. Here too, it is conceivable that the alarm device 35 emits a corresponding alarm signal, for example, visual and / or audible. The service life of the individual electronic devices within container 1 can be improved by maintaining a certain temperature within the cargo space 4 during loading operations. For this purpose, an air conditioning unit 60 can be arranged within the cargo space 4. As shown in Fig. 2, the air conditioning unit 60 is attached to the roof 9 of the enclosure 3. The air conditioning unit 60 can also interact with a heater 61, which, as shown in Fig. 2, can be located within the side walls and / or rear walls of the enclosure 3. For safety purposes, a fire extinguishing device 70 is positioned on the roof 9 inside the cargo space 4. Below the battery holder 13 is a collection device 6 to catch any medium that may leak from the battery 2 and / or the energy converter 12. The closing element 7 according to Fig. 1 can be, for example, a sliding door, a roller door, or a hinged door. The energy converters 12 are located on a base element 16, which is positioned above the battery holder 13. In Fig. 2, a water refill station 50 is also positioned in the cargo space 4. If a battery 2 has insufficient water, it can be refilled manually or automatically via the water refill station 50. Figure 1 schematically shows a safety element 17 located in the battery charging compartment 10. The safety element 17 serves as protection for the wall of the housing 3, in particular for the rear wall 8. Figure 2 further shows several indicator elements 32, which can, for example, indicate whether a battery 2 is occupied or not in the battery charging slot 10, or visualize the state of charge of the battery 2. For example, if a battery 2 is fully charged, the indicator element 33 can emit a green light or a symbol. If a battery 2 is only partially charged, the indicator element 33 emits, for example, a red color or another symbol. An occupancy or vacancy of the battery charging slot 10 can be indicated, for example, by other colors or symbols. Of course, the indicator element 33 can be a display, which allows the occupancy and / or vacancy of the battery slot, as well as the state of charge of the battery 2, to be visualized in a different way. Each battery charging slot 10 has its own indicator element 33. The indicator element 33 is located within the charging compartment 4 on the roof 9 of the housing 3.Of course, the display element 33 can also be arranged in different positions within the respective battery charging station 10, for example on the power supply system 30, rail element 31, control unit 34, or on the base element 16. Alternatively and / or additionally, the display element 33 can also be arranged outside the charging compartment 4 on the housing 3, as shown schematically in Fig. 4. Likewise, only one display element 33 can be provided for all battery charging positions 10. Fig. 4 shows another embodiment in which a renewable energy system 80 is provided, arranged on the roof 9 of the enclosure 3. The roof 9 can have a lean-to roof 90 that projects to the right beyond the dimensions of the mobile container 1, meaning that the lean-to roof 90 can have a projection of, for example, 1 m to 2 m. The lean-to roof 90 serves as protection against rain and / or snow and advantageously extends over the entire width of the container 1. This lean-to roof 90 also helps to reduce the heating of the cargo space 4 by solar radiation. The renewable energy system 80 is advantageously connected to the energy supply system 30 and can thus provide energy for charging the batteries 2. Figure 2 shows a control unit 34, which is arranged on the housing 3 outside the container 1. The control unit 34 is electrically connected to the power supply system 30. Advantageously, a signal connection also exists to the ventilation system 20 and / or the monitoring unit 24 and / or the display element 33 and / or the alarm device 35 and / or the gas monitoring unit 40 and / or the air conditioning unit 60 and / or the extinguishing device 70 and / or the renewable energy system 80. In addition, the control unit 34 can be in signal communication with a transmitter and / or receiver unit 110, as shown in Figures 1, 2, and 5. As shown in Fig. 5, the invention relates to a system 100, which can be configured with several containers 1, all of which are in signal communication via the respective transmitting and / or receiving unit 110. All data can be exchanged between them, such as the state of charge of the individual batteries 2 or the utilization of the battery charging stations 10. For example, it is conceivable that a main controller 36 is integrated into the system 100, which collects this information from the individual mobile containers 1, forwards it, and in particular transmits it to third parties, such as a data cloud. In a practical embodiment, the user can obtain information about the current state of charge and the current utilization of all containers 1. The user can receive information from the system 100 according to the invention indicating in which container 1 the user can obtain and remove their appropriate charged battery 1.Or into which container 1 he can place his discharged battery 1. Figure 1 also shows a light 32, which is attached inside the container 1 to the roof 9 of the enclosure 3. The light 32 can be switched on or off via a push button, or alternatively, operated automatically via a timer. The light 32 can also be switched on or off automatically, for example, by a motion detector. To allow the container 1 to be moved easily and without effort, support elements 18, in particular feet, are provided on its underside, so that the container 1 can be moved, for example, using a forklift. The forklift can drive its support arms under the bottom wall 19 of the enclosure 3 and thus lift and move the mobile container 1. Lifting elements, in particular eyelets, can be provided on the roof 9 so that the container 1 can be moved into position using a crane and the associated lifting lugs or chains.
