Lease type charging device and system and charging method

Abstract

The invention is applicable to the technical field of charging and discloses a lease type charging device. The lease type charging device comprises a charging controller connected with a charging power takeoff end and a connector connected with the charging output end in signal connection with the charging controller, wherein the charging controller comprises a microprocessor, a control key connected with the control end of the microprocessor and a switch circuit connected with the output end of the microprocessor to control charging output, the switch circuit controls charging between the power takeoff end and the connector through signal control of the microprocessor, solid-state passwords consisting of multiple groups of passwords are set for the microprocessor, the control end of the microprocessor outputs a control signal for controlling breakover of the switch circuit when an input password is matched with any one group of passwords among the solid-state passwords, and the connector and the charging power takeoff end form a charging circuit. Due to the fact that the charging device can be controlled to work by obtaining the passwords, by-time or timed charging is achieved, charging is avoided when a user needs to carry or purchase a charger, and purchasing cost or carrying inconvenience of the user is reduced.

Description

technical field [0001] The invention relates to the technical field of charging portable equipment, in particular to a rental charging device, system and charging method. Background technique [0002] Existing mobile terminals, such as mobile phones or digital products, usually need to be charged by the mains, such as wall chargers, car chargers or USB cables, which requires users to take them with them at any time when they are in use, so that they can be charged when the device is out of power. Charging, because the charger usually has a wire harness and a charging head, when people usually go out, it is easy to forget to carry it. It is easy to happen that the mobile terminal cannot be charged when it is out of power. Because there is a rental mobile power supply, although the rental mobile power supply can solve the problem of instant charging. However, in order to avoid power loss when renting a mobile power supply, deposits need to be provided, which increases the co...
