Problems solved by technology
[0002] The existing various battery charging technologies are generally divided into two parts: wired charging and wireless charging. For wired charging, there must be actual physical wire connections and ports, which are very important for various protections of ports and applications in certain fields. It is very inconvenient. For wireless charging, it overcomes the shackles of wired, but in the charging management area, many solutions still use dedicated battery management chips to manage the charging of different battery systems. For battery-operated products, it is undoubtedly a large cost consumption
In addition, for some wired or wireless products without dedicated chip management, there are some problems such as repeated charging to reduce the battery life, or the battery cannot be fully charged and saturated.

The invention discloses a battery induction charging device and system and a control method. The battery induction charging system includes a charging emission module and a battery induction charging device. The battery induction charging device includes a battery, an induction coil, a charging circuit, a switching circuit, and a controller. The induction coil induces a radio electromagnetic wave energy signal emitted by the charging emission module. The radio electromagnetic wave energy signal is converted into a charging signal of the battery through the charging circuit. The detection end of the controller detects the battery voltage after receiving the charging signal. When the battery voltage is low, the charging control end of the controller sends a switch-on signal to the switching circuit to charge the battery. When the charging is completed, the controller enters a dormant state. Only when an energy consumption detection end detects an external energy consumption event, the controller is awakened to a working state to charge the battery. Thus, the system is prevented from charging the battery repeatedly. The charging efficiency of the battery is improved. Resources are saved. The service life of the battery is prolonged.
Description
technical field [0001] The invention relates to the technical field of charging, in particular to a battery inductive charging device and its system and control method. Background technique [0002] The existing various battery charging technologies are generally divided into two parts: wired charging and wireless charging. For wired charging, there must be actual physical wire connections and ports, which are very important for various protections of ports and applications in certain fields. It is very inconvenient. For wireless charging, it overcomes the shackles of wired, but in the charging management area, many solutions still use dedicated battery management chips to manage the charging of different battery systems. In terms of battery-powered products, it is undoubtedly a large cost consumption. In addition, for some wired or wireless products without dedicated chip management, there are some problems such as repeated charging to reduce the battery life, or the batte...
