Description

The invention relates to an arrangement comprising a measuring socket, a battery connected thereto and a terminal, wherein the measuring socket has a radio module for communication with a terminal having a receiving module, wherein the measuring socket comprises a relay switching the charging process.

Furthermore, the invention relates to a method for charging a rechargeable battery with such an arrangement.

The state of the art is US 2009/0195349 A1 a system and a method for monitoring the energy consumption of home applications is disclosed. For this purpose, measuring devices are arranged in the individual sockets, in multiple sockets or in the individual consumers, which directly determine the energy consumption of the connected consumers or of the consumer and transmit it to a centrally arranged base unit. Based on these measured data from the consumers, the energy consumption can be displayed.

Measuring sockets that allow both energy and power measurement via an energy and/or power measuring device have also recently become known: www.jung-group.com/de-DE/JUNG-HOME-SCHUKO-Steckdose-Energy-Safety-alpinweiss/BT-LS-1521 -SE-WW and www.merten.de/produkt/meg2380-0319-connected-schuko-steckdose-16a-system-m-thermoplast-brillant-polarweiss-glaenzend.html#tabspecifications Such sockets also advantageously allow connected consumers to be switched and the recorded energy and/or power measurements to be sent to a central evaluation unit, so that an evaluation and visualization of the energy and/or power data is possible.

The problem with the measuring socket described above is that charging a battery is not as precise and/or convenient as the user has to stop the charging process themselves - unless they accept that the battery will be fully charged. However, this is not usually desired in order to preserve the battery's service life, so the battery is ideally only charged to 85% or 90%. In addition, depending on the application, if the battery is not used for a long time, it may also be useful to aim for a target battery charge level of around 50% in order to avoid deep discharging the battery, especially if the battery is not used for a long time with a battery charge level of less than 10%. Furthermore, for certain applications it may be desired that a certain amount of energy is charged into a battery, for example in an electric car or an e-bike, if the energy is purchased instead of generated from a solar system.

Based on this discussed prior art, the invention is based on the object of proposing an arrangement comprising a measuring socket, a rechargeable battery connected to it and a terminal device, which makes it possible in a convenient and precise manner to charge a rechargeable battery with a defined amount of energy and/or to charge it from a starting battery charge state to a target battery charge state.

This object is achieved by an arrangement comprising a measuring socket, a rechargeable battery connected to it and a terminal, wherein the measuring socket has a radio module for communication with a terminal having a receiving module, wherein the measuring socket comprises a relay that switches the charging process, characterized in that the terminal has an input interface for entering a starting battery charge level and a target battery charge level and/or an amount of energy, that the socket or the terminal has a memory in which at least one rechargeable battery is stored with regard to its charging curve and/or the energy content, wherein the measuring socket identifies the rechargeable battery connected to it by means of a measuring and control device and switches the charging process on and off using the relay.

The core idea of the invention is that the arrangement according to the invention for charging a battery, due to the ability to store a charging curve and/or an energy content of the battery in a memory, is able to identify the battery connected to it using a measuring and control device of the measuring socket and to switch the charging process on and off using the relay. The starting battery charge level and the target battery charge level and/or the amount of energy to be charged are entered by the user via an input interface of the terminal device. This ensures that the target battery charge level and/or the amount of energy to be charged are reached or charged precisely and conveniently. It is particularly advantageous that the battery connected to the socket is automatically identified due to the recognition of the connected battery by comparing the charging curve with charging curves already stored in the memory. ulator without, for example, the total energy content of the battery having to be specified for each charging process. In this respect, the inconvenient regular input/selection of the connected battery (or the input of further parameters relating to energy content) can be dispensed with. This intelligently exploits the technical infrastructure that is already present in a known measuring socket that also has a relay for switching in order to optimize the charging process of a battery in terms of its precision and convenience.

For this purpose, the measuring socket of the arrangement according to the invention has, in addition to a relay that switches the charging process, a radio module for communication with a terminal device having a receiving module, in particular a mobile terminal device.

According to the invention, the measuring socket itself or the terminal device comprises a memory in which at least one accumulator is stored with regard to its charging curve and/or energy content. Such storage takes place by connecting a battery, preferably with an initial charge level of less than 20%, in particular 0%, to the measuring socket once and starting the charging process and carrying it out to 100%. The measuring device records the charging process, in particular with regard to the current and/or voltage curve. The charging curve and/or the energy content of the accumulator thus determined are then stored. In contrast to a selection or input that would otherwise have to be made, this storage takes place once, so that the convenience for the user is particularly high.

The user can enter the starting battery charge level by either using a completely discharged battery, i.e. with a starting battery charge level of 0%, or by reading the battery level, for example, via a display on the device that is powered by the battery. Such a display can be, for example, the battery charge level display on an electric car, a mobile device or a notebook. The value determined in this way is then entered into the input interface.

A target battery charge level is entered without having to read out the current charge level. The desired target battery charge level, for example 90%, is simply entered into the input interface of the end device.

The arrangement according to the invention is thus sufficiently initialized to carry out the charging process comfortably and precisely. It goes without saying that the charging process is automatically aborted by switching the relay when the desired target battery charge level and/or the desired amount of energy is reached.

According to a preferred embodiment of the invention, the measuring socket sends a message regarding the current charging status to the terminal device via the radio module. This conveniently informs the user of the arrangement according to the invention about the charging progress.

According to a particularly preferred embodiment of the invention, the measuring socket sends a message to the terminal device via the radio module regarding the completed charging status. This has the positive aspect for the user that he is automatically informed when the desired charging process has been completed, so that the connected device powered by the battery can be used without any noticeable loss of time.

According to a particularly preferred embodiment of the arrangement according to the invention, the terminal has a visual and/or acoustic display for showing the charging status.

According to a particularly preferred development of the arrangement according to the invention, the entered target battery charge level can be stored on the terminal as a suggested value for further charging processes. This further improves convenience for the user because the target battery charge level, for example a value of 90%, is stored and can be called up as a suggested value.
