Problems solved by technology
During the charging process of the battery, due to the impedance of the charging circuit, there will be heat generation, which will cause a burden to the operation of the charging circuit; The insulation performance of the charging circuit is reduced
Although corresponding protection measures are installed in the charging circuit of the battery, most of them adopt the method of cutting off the circuit in exchange for circuit protection, which greatly reduces the charging efficiency, so there is still room for improvement

The invention discloses a charging system which helps solve a problem that a charging loop circuit is prone to overcurrent phenomena and shortened service life due to long-term operation. A technicalsolution of the charging system is that if a controller detects that the charging port is connected to an external power source and is used for charging a storage battery, the controller sequentiallyturns on input loop circuits; the controller controls each output loop circuit to be consistent with a corresponding input loop circuit in terms of on-off state. In the charging system disclosed in the present invention, the charging circuit of the storage battery consists of a plurality of channels; when the charging port is connected with the external power source, the storage battery can be charged through the charging loop circuit. During charging processes, one channel is always kept in an on state to ensure that the storage battery can be charged normally, and therefore charging efficiency can be prevented from being affected; the controller is used for switching the channels in the charging loop circuit at regular intervals, and therefore the plurality of channels are turned on in turn to prevent a single channel from running for a long period of time, the charging loop circuit can be prevented from overcurrent or even short circuit phenomena, and the service life of the charging loop circuit can be prolonged.
Description
technical field [0001] The invention relates to a charging system. Background technique [0002] At present, with the popularization of electronic products, people pay more and more attention to the charging safety of electronic products. Electronic products are usually provided with a storage battery to provide a corresponding battery life of the product. When the battery is exhausted, it needs to be charged in time. During the charging process of the battery, due to the impedance of the charging circuit, there will be heat generation, which will cause a burden to the operation of the charging circuit; As a result, the insulation performance of the charging circuit is reduced. Although corresponding protection measures are installed in the charging circuit of the battery, most of them adopt the method of cutting off the circuit in exchange for circuit protection, which greatly reduces the charging efficiency, so there is still room for improvement.
