Problems solved by technology
[0004] (1) When not charging, the charging port needs to be closed to achieve more security strategies and reduce static power consumption, and the operation is complicated;
[0005] (2) Before the charger is connected, no discharge circuit is allowed, otherwise the signal will be triggered through the discharge circuit, and the detection purpose will not be achieved
[0006] (3) The cost is increased, the control logic of the discharge circuit is limited, and the static power consumption is increased. It is impossible to judge the voltage of the charger and the battery. Even if the voltage of the charger is lower than that of the battery, the charging signal will be triggered

The invention discloses a detection method and a detection circuit for charger charging. The detection method comprises the following steps: configuring a charging detection circuit between a charger and a battery; judging whether the output voltage of the charger is greater than the storage voltage of the battery, if yes, allowing charging, and if not, forbidding charging; and monitoring the voltage state of the charger and the voltage state of the battery in a charging process, if the voltage of the charger is greater than the voltage of the battery, continuing charging, and if not, stopping charging. According to the detection method and the detection circuit for charger charging disclosed by the invention, the level input of a charged MCU is controlled through the turning-on and turning-off of a triode, so that the charging state of the charger for the battery is controlled, and a protection unit can be used for guaranteeing the safety of the charger and the safety of the battery in abnormal conditions; the detection circuit is reliable, safe, concise and low in power consumption; and a scientific method and a circuit system are supplied for charging detection of the battery.
Description
technical field [0001] The invention relates to the technical field of charging circuits, in particular to a charger charging detection method and a detection circuit. Background technique [0002] In recent years, rechargeable batteries have been widely used in mobile phones, notebook computers, portable power supplies, electric vehicles, electric tools and other fields, which have played an important role in improving people's environmental protection and energy saving levels, and also provided great benefits for people's efficient and fast life. Conveniently, in the prior art, the charger detection circuit consists of the following two parts: a charger detection trigger circuit, and a charging indication signal, which is a charging method of charging first and then detecting. [0003] There are at least the following problems in the prior art: [0004] (1) When not charging, the charging port needs to be closed to achieve more security strategies and reduce static power ...
