Field device of automation technology

A charging system for a field device of automation technology, comprising:

• a housing;
• the charging system electronics arranged in the housing;
• a transmitting unit with a transmitting coil for transmitting energy wirelessly inductively;
• and
• an energy supply unit arranged in the housing for energy supply of the charging system electronics and for providing energy to be transmitted wirelessly inductively via the transmitting coil;
• wherein the transmitting unit and the transmitting coil are adapted to transmit energy wirelessly inductively as defined in a Qi standard 1.2.4 or a standard derived therefrom.

A system of automation technology, comprising:

• at least one field device, including:
• a field device housing;
• a field device electronics arranged in the field device housing;
• a first rechargeable battery arranged in the field device housing for energy supply of the field device electronics;
• and a receiving unit with a receiving coil for receiving wirelessly inductively transmitted energy, wherein the receiving unit is connected with the rechargeable battery, so that received, wirelessly inductively transmitted energy is storable, and is stored, in the rechargeable battery;
• wherein the field device electronics is adapted in such a manner that energy supply occurs exclusively or at least partially from the first rechargeable battery and wherein the receiving unit and the receiving coil are adapted to receive wirelessly inductively transmitted energy as defined in a Qi standard 1.2.4 or a standard derived therefrom and to store such in the first rechargeable battery;
• and
• at least one charging system, including:
• a housing;
• the charging system electronics arranged in the housing;
• a transmitting unit with a transmitting coil for transmitting energy wirelessly inductively;
• and an energy supply unit arranged in the housing for energy supply of the charging system electronics and for providing energy to be transmitted wirelessly inductively via the transmitting coil;
• wherein the transmitting unit and the transmitting coil are adapted to transmit energy wirelessly inductively as defined in a Qi standard 1.2.4 or a standard derived therefrom;
• wherein the charging system has a first coupling section and the field device has a second coupling section, wherein the transmitting coil is arranged in the first coupling section of the charging system and the receiving coil in the second coupling section of the field device, wherein a surface contour of the first coupling section is matched to a surface contour of the second coupling section, so that the charging system can be placed on the field device housing and in a placed on state energy transmittable is, and is transmitted, wirelessly inductively.
