Problems solved by technology

In other words, it is mainly through the timer, and the charger is automatically disconnected after the time is up. The disadvantage is that the charging time cannot be automatically determined according to the battery capacity. If the battery capacity is large, the battery cannot be fully charged. question

Embodiment Construction

[0012] As shown in Figure 1-2, the present invention includes an input terminal, a rectifier, a transformer and an output terminal, the input terminal, the rectifier, the transformer and the output terminal are connected in sequence, and a power-off device is provided between the input terminal and the rectifier device. A detection module is provided on the output end, and the power-off device is connected with the detection module.

[0013] The detection module includes a controller, a current transformer and a signal transmitter, the current transformer is connected to the signal transmitter, and the power-off device and the signal transmitter are respectively connected to the controller.

[0014] The current transformer continuously detects the current value of the output terminal, and transmits it to the controller through the signal transmitter. Whether it is full or not, the power will be cut off when the time comes, and it also solves the problem of overcharging or ins...

Abstract

The invention provides an automatic power-off charger, and relates to a charging device, particularly an automatic power-off charger. The automatic power-off charger can automatically judge the charging time to conduct the power-off action according to the capacity of a battery. An input end, a rectifier, a transformer and an output end are connected in sequence. A power-off device is arranged between the input end and the rectifier. The output end is provided with a detection module. The power-off device is connected with the detection module. The detection module comprises a controller, a current transformer and a signal transmitter. The current transformer and the signal transmitter are connected together. The power-off device and the signal transmitter are connected with the controller respectively. The controller adopts a programmable logic controller. The power-off device comprises a contactor. The automatic power-off charger is safe and stable, and the service life of the automatic power-off charger is prolonged. The problem in the prior art that based on the timing function of a timer, the power-off action cannot be conducted according to the capacity of the battery can be solved.

Description

technical field [0001] The invention relates to a charging device, in particular to an automatic power-off charger. Background technique [0002] With the development of society, there are more and more devices that need to be charged, such as electric vehicles and mobile phones. The existing chargers generally need to be plugged and unplugged manually. Once the battery is overcharged, it will damage the battery and waste power, or cause the battery to overheat. lead to safety incidents. [0003] The State Intellectual Property Office published an invention patent application on 2014-02-19 (application number: 201210292034.3 name: an automatic power-off device for a charger) disclosing an automatic power-off device for a charger, specifically disclosing a controller, a transformer , a switch and a charging device, the transformer is connected to an external AC power supply, the other end of the transformer is connected to the switch, the input end of the controller is conne...
