A control device for power supply time of timers comprises an alternative current (AC) power source input module, a direct current (DC) power source supply module, an AC power source output module electrically connected to a load end, a relay, a central control module, a relay driver circuit, a day/night detecting module, a power supply time backward display light set, a power supply time forward display light set, a power supply time backward selection control button and a power supply time forward selection control button. Herein, by pressing the power supply time backward selection control button or the power supply time forward selection control button, one of the power supply time backward display lights or the power supply time forward display lights can be turned on such that the central control module can, based on the sunset time of the previous day as well as the configured power supply backward setting time or power supply forward setting time, postpone or advance the power supply time for the load end in the next day, and then record the sunset time of the next day so as to control the power supply time for the load end in the further next day.

A charging device includes: a plurality of main relays forming a connection between an electric vehicle (EV)-side connector and an outlet-side connector; a relay welding sensing unit connected to the plurality of relays to sense the presence or absence of welding of the plurality of relays; a welding monitoring relay opening and closing between the relay welding sensing unit side node and a main relay side node; and a control unit controlling the open and close of the welding monitoring relay.

An overload protection switch with reverse restart switching structure, particularly to one that has a molded-case circuit breaker which adding a lampshade parallel stagnation position for overload indication, and when resetting, needs to press back to the RESET for reconfirmation; due to the stagnation position and reverse restart structure, it can avoid repeating the reset action, preventing the reduction of the life of the overload protection switch and repeated exposure or the misjudgment and then resetting of electrical products that have been overloaded and tripped and then overload again then results in causing dangerous; also, the lampshade can be completely tripped even when the lampshade is suppressed, and prevent the danger of repeated tripping during overload.

A switching device includes at least one main contactor, a control power supply and an actuator configured to cause the main contactor to change from an open to a closed state against a force generated by the spring. The contactor has a blade and at least one terminal, the blade being configured to assume a position in contact with the terminal and a position not in contact with the terminal. The switching device includes a detection system configured to determine the contact or non-contact blade position of the main contactor, to generate at least one second signal as a function of the determined blade position of the main contactor and to transmit the second signal to the control power supply. The control power supply is configured to generate a control signal configured to keep the main contactor in the closed state upon reception of the second signal.

A circuit for a circuit interrupter is provided. The circuit may in include a first SCR configured to receive a first trigger signal at a gate of the first SCR, a second SCR configured to receive a second trigger signal at a gate of the second SCR, and a third SCR configured to receive a third trigger signal at a gate of the third SCR. A cathode of the first SCR may be connected to an anode of the third SCR. A cathode of the second SCR and a cathode of the third SCR may be connected to a ground. Methods of operating a circuit interrupter and a circuit are also provided.

A battery system includes: a battery management system comprising a DC/DC converter and a system basis chip; a microcontroller connected to the system basis chip to receive power from the system basis chip; and a relay driver configured to control a relay. The DC/DC converter receives power from a power source, and the system basis chip receives an output voltage from the DC/DC converter. The relay driver is connected to a node between the system basis chip and the DC/DC converter to receive the output voltage from the DC/DC converter. The microcontroller is electrically connected to the relay driver and is configured to: before switching the relay, control the DC/DC converter to increase the output voltage from a first voltage to a higher second voltage; and control the relay driver to switch the relay while the DC/DC converter outputs the second voltage.
