Charger and unmanned aerial vehicle system

Abstract

Embodiments of the present invention provide a charger (100) and an unmanned aerial vehicle system, comprising: a power input interface (101), a power output interface (102), a control circuit (103),and a charging switch (104). The power input interface (101) is used to access a power source. The power output interface (102) is electrically connected to a battery (200). The charging switch (104)is connected in series between the power input interface (101) and the power output interface (102). The control circuit (103) is electrically connected to the charging switch (104) and can control the charging switch (104) to be turned on and off. The control circuit (103) is capable of collecting information of the battery (200), the information of the battery (200) comprising information of a plurality of cells comprised in the battery (200). When the battery (200) can no longer accept further charge, the control circuit (103) can control the charging switch (104) to be turned off so as tostop the charger (100) from continuing to charge the battery (200). The charger (100) presented in the embodiments of the invention provides greater safety for charging the battery (200).

Description

technical field [0001] Embodiments of the present invention relate to the technical field of batteries, and in particular to a charger and an unmanned aerial vehicle system. Background technique [0002] In order to improve the performance of a single battery, the power source used in many devices that need power is a battery. Wherein, the battery may include a plurality of electric cells. [0003] There may be unusable batteries in the battery, or there may be two batteries with a large voltage difference between the batteries. In these cases, if the existing charger is used to continue charging the battery, safety accidents may occur. For example, the battery fire. However, the existing chargers can only simply provide a current and voltage to charge the battery, and cannot independently control the opening and closing of the battery charging, so the safety of charging is relatively low. Contents of the invention [0004] An embodiment of the present invention provide...
